[[caption-width-right:306:Yet exactly ''how'' young is a mystery to everybody!]]

Some characters are subject to a strange fluctuating sense of maturity depending on plot necessity, mostly because animated characters can have [[ArtisticAge abstract designs and lack obvious visual cues]]. We're only left with the personality of the character, which tends to suggest their age. DawsonCasting, leading to a blurring of the line between adults-playing-adults and adults-playing-teenagers, is responsible for several live-action examples.
A TV character may be implied to be some sort of ''adult'' compared to other characters who are clearly "kids", or vice versa, but this is largely an illusion in case the writers still want them in plots a younger audience can more easily relate to. The only nominally-aged character is usually the lead, and this is only useful to make his same-aged audience feel better, since he will probably [[NotAllowedToGrowUp not be allowed to get older]].

Occasionally, characters are given specific ages along with more obscure and extensive biographies, but are ultimately ruled by audience appeal, CastSpeciation, and personalities that fit into the mean age of the audience. Information that runs counter to that turns into the ImprobableAge issue, and may be tweaked in other places.

[[folder: Anime and Manga ]]

* Mireille of ''Manga/DotHackLegendOfTheTwilight'', who can be very knowledgeable at times, sometimes lord it over others, and sometimes just be cute and vulnerable. [[spoiler: She actually turns out to be the four-year-old daughter of an [[IdenticalGrandson identical character]] from the first game, using her mother's file, and one of the other girls in Shugo's {{harem}} is her home tutor, explaining some of it.]]
* ''Franchise/LupinIII'': The characters are certainly adults, but beyond that it's anyone's guess. The fact that they have been having adventures since TheSixties can be ignored since the series runs on ComicbookTime. However, Lupin himself is canonically the [[IdenticalGrandson grandson]] of Literature/ArseneLupin, who first appeared over a century ago, already an adult. At this point, the timeline would make a lot more sense if it were called Lupin the Fourth or even Lupin the Fifth.
* ''LightNovel/{{Baccano}}'' makes it rather difficult to determine Ennis's physical ''or'' chronological age, as her origin is [[ArtificialHuman somewhat]] [[OurHomunculiAreDifferent complicated]] and not too many details are given on her timeline in either the anime or LightNovels beyond three tidbits: she was around before the commercialization of radio (with the given [[HistoricalFiction setting]], means she can be anywhere from eight to two hundred and nineteen), she's physically the same age as her "mother" was when she unwillingly "donated" some of her cells (nothing is given about this girl/woman other than that she was female, so that gets us nowhere), and that she identifies Firo on sight as "around the same age as her, or a little younger" (which, given that Firo's an eighteen-year-old [[OlderThanTheyLook regularly mistaken to be as young as fourteen or fifteen]], also gets us nowhere).
* Played with in ''[[JungleWaItsumoHaleNochiGuu Haré+Guu]]''. When attending [[{{Eagleland}} The City's]] school, Haré immediately notices all the kids are separated by grades. His own school is a literal [[TwoTeacherSchool one-teacher]] and his homeroom consists of ''every'' non-adult in the series, including teenagers. [[note]]Which incidentally is TruthInTelevision for extremely low population density areas; a single teacher is able to give individualized assignments for each student based on their age, when there's only a handful of them to begin with.[[/note]]
* ''{{Kobato}}''. She certainly ''acts'' a lot younger than a teenager, but from her design and the way other characters treat her she seems to be at least twelve and probably not old enough to be in high school.
* Applied to Luna the cat in ''Series/PrettyGuardianSailorMoon'', who despite sounding identical to the version in ''Anime/SailorMoon'' (who was a VagueAge full grown cat until she briefly became a [[HumanAliens human(oid)]]), was given the body of a very young girl as a occasional human form. She was described by mangaka Creator/NaokoTakeuchi as being a year younger than the lead character and became a teenaged girl when human, but also has been alive since the Silver Millennium.
** Likewise Usagi's younger brother's age can fluctuate from between two and four years younger than her depending on whether you're watching TheNineties anime, the live-action series, or reading [[Manga/SailorMoon the manga]].
* Sunrise has been rather opaque about the ages of the heroes in ''TigerAndBunny''. So far, they've only given out two and a half: Barnaby's 24, Kaede's 9, and Kotetsu's kinda sorta probably somewhere between 33 and 39. [[ShrugOfGod Maybe]].
* Coby of ''OnePiece'' appears to be child much younger than Luffy (who is 17 at the beginning of the story), but enlists in the marines as soon as he's saved [[spoiler: and then apparently goes through puberty and has a growth spurt by the next time we see him.]]
** Shakky is an even better example. She mentions that she was chased by Garp and stopped pirating 40 years ago, which would probably make her more than 60 (at least not a day under 55). But she looks like she is in her late twenties or early thirties, and the characters have questioned her age several times. So she could be anywhere from 60 to more than 100 since it would be unrealistic for an older woman to look like a 30-year-old no matter what.
* Satoko and Rika from ''HigurashiNoNakuKoroNi''. They're noticeably younger than the protagonists but how much younger is never quite stated. Satoko seems to have entered puberty but Rika hasn't yet. The closest we get to an age confirmation is in the original sound novels, and even then all we know is that Satoko is anywhere from 9 to 13 years old.
* Amae Koromo from ''Manga/{{Saki}}''. Though she appears very child-like, she is a second-year student as opposed to the majority of Kiyosumi High's players like Saki, Nodoka, and Yuuki who are first-years, and it's been hinted that she's older than Nodoka.
* Satsuki Hyoudou from ''Manga/MaidSama''. Despite looking like a teenager, she is actually 30 years old.
* Mikuru Asahina from ''LightNovel/HaruhiSuzumiya''. Although she looks like a {{moe}} teenager, when Kyon asked her how old she really is after she revealed her true origin and purpose, she merely responded, "That's classified."
* Levi (and a few others) from ''Manga/AttackOnTitan''. Levi is noticeably smaller than many character, including the 15 year old protagonists, and looks younger than a few of the trainees, but in reality he has to be anywhere from three to ten years older than them. WordOfGod says he's "[[OlderThanTheyLook surprisingly old]]", though no exact age has been given.
* ''Manga/{{InuYasha}}'': Kikyo is accepted to be in her mid-to-late teens, but her exact age is uncertain. The ''[=InuYasha=] Profiles'' book states that she was eighteen when she originally died, whereas [[WordOfGod Rumiko Takahashi]] said she was "around seventeen" when it happened.
** Likewise, the exact ages of all {{youkai}} and [[HalfHumanHybrid hanyou]] characters is left deliberately ambiguous.
* In ''Manga/FairyTail'', Natsu's age hasn't been revealed even though most other members have a known age. Because he couldn't pass through Freed's barrier in the Battle of Fairy Tail, he is either 80+ years old (which seems a bit weird since he obviously has aged as he looked like a kid 6 years ago and a teenager now) or a stone statue (which makes even less sense). In terms of personality and appearance, he is probably supposed to be seen as being Lucy's age (17 years), as he looks a bit younger and acts more immature than 18-year-old Gray.
* This was the case for most of the 00 cyborgs in ''Manga/{{Cyborg009}}'', as Ishinomori never gave them established ages- with the exception of 009, who was 18 and 001 who was of (vague) infant age. The anime adaptations settle on 007 being the oldest (except for the '60s incarnations which made him a 9-year old KidAppealCharacter) and in his '40s, 006 being a little younger than that, 005 and 004 either being in their late '20s or early '30s, 008 being in his early '20s, and 002 being in his early '20s or being 18 like 009. 003 either winds up younger than 009 in the earlier anime adaptations, being 16 or 17, or she's older in the '01 incarnation (physically 19, but chronologically ''much''' older due to being cryogenically frozen in the '60s).
* None of the ''Manga/GunslingerGirl'' cyborgs have a given age. Henrietta seems to be between eleven and thirteen while Triela is a little older. To make it more confusing they seem to be [[NotAllowedToGrowUp stunted]] at the age they were Conditioned at and possibly years have passed between their backstory and the final chapter, so that leaves it vague what their biological ages are.
* ''Kaitou Joker'' seems to be a world of characters with amibigious ages.
* ''LightNovel/HighSchoolDxD'' is rife with this, thanks to reincarnated devils having their aging slow down dramatically from the moment they're reborn. Rias is a high school senior, but as a pure-blooded devil it's plausible she's pushing quadruple digits. Akeno looks exactly the same age, but is significantly younger. Issei, Asia and Xenovia are exactly the age they look thanks to having been recently reincarnated, but Kiba is heavily implied to be decades older despite being in the same school year. And all three of them are stated to be much younger thank Koneko, a tiny underclassman who could well be over a century old, and Gaspar, whose {{Dhampir}} nature only further muddies the waters.
* While she's clearly older than Tsutomu, the age of the title character of ''Anime/BirdyTheMighty'' was never stated in the OVA or ''Decode''. In the OVA series, Tsutomu chastises Birdy for drinking alcohol due to a combination of the possibilty of getting drunk while on duty and her being underaged, which given the legal drinking age in Japan is 20, suggests Birdy in the OVA series is at the oldest 19. However, in ''Decode'', Birdy's age is easier to determine as we get flashbacks to her when she was 10, a friend of hers while she was that age says he hasn't seen her since she seen her for 14 years, and Tsutomu only reprimanding her for getting drunk suggests at the youngest, she's 24 there.
* ''Anime/{{Pokemon}}'':
** Unlike the games the protagonists are given clear ages of ten years old however the Pokemon themselves are a mystery. Meowth is apparently an adult but everyone else is up in the air. Do Pokemon age when they evolve? If a baby Pokemon never evolves are they always considered a child? Is Donphan a ManChild or a [[HugeSchoolgirl large child]]? Bulbasaur and the others are largely assumed to be 'child Pokemon' but an early joke had them drunk and their species can breed. Whether Pikachu is an adult Pokemon or the equivalent of Ash's age has been debated.
** Most characters besides the protagonists have no age. Brock is fifteen according to supplementary material but unless their age is given in the games it's unlikely anyone's age is given in the anime.
** Jessie and James. The only certainty is they're older than any of Ash's tagalongs. Jessie once said she was seventeen but that's probably her trying to seem younger than she is, and flashbacks imply she finished high school. The Japanese version has implied they're twenty-five once.


[[folder: Comic Books ]]

* ''{{Asterix}}'': Asterix himself is described as being "older than he looks." Between the art style used for all the characters, and the features of Asterix himself, he looks somewhere between 20 and 60. What that actually makes him is anyone's guess. Lampshaded in ''The Cauldron'', where he's working for a wrestling promoter who actually describes him in his 'roll-up' pitch as being 'of indeterminate age'. (One short story strip of dubious canoninity (due to being outside of an official volume and containing some inconsistencies with other stories) states Asterix and Obelix are 35 "when their adventures begin".)
* WesternAnimation/DonaldDuck's nephews, Huey, Dewey, and Louie in Carl Barks' comics. In one story they are in kindergarten; in another they are shown driving a car! (The "kindergarten" they are attending is a rather unusual one, however; in the background of the first panel, there appears to be an [[EEqualsMCHammer integral equation written on the blackboard]].)
** Also Donald Duck himself. It's obvious that he is not really young or old, but it's not clear (and it [[DependingOnTheWriter depends on the writer]]) if he's still somewhat young like in his late twenties or he is middle-aged.
* Franklin Richards, the child of ''ComicBook/FantasticFour'' members Mr. Fantastic and the Invisible Woman, is somewhere between four and ten. Whether his [[RealityWarper reality warp]] power cause the age vagueness or if the age vagueness ''causes'' the reality warping is up for debate.
** It has also been suggested that he is the source of [[ComicBookTime whatever effect it is]] that has kept the Fantastic Four's [[SuperHeroOrigin maiden flight]] [[SlidingTimescale "about ten years ago" for the last thirty years or so]].
* ''ComicBook/GastonLagaffe'': Lagaffe is old enough to smoke and have a car, a job, and his own place, but young enough to constantly play around at work and bawl his eyes out over very little.
* ''ComicBook/SpirouAndFantasio'': Spirou spent the 1950s stuck in a limbo where he looked like a teenager (being [[OneHeadTaller one head shorter]] than his adult friend Fantasio), but drove a car and had his own apartment. He finally became unambiguously adult shortly before or after Creator/AndreFranquin left the series.
* JimmyOlsen, {{Superman}}'s Pal, would go back and forth between being old enough to drive, have a pilot's license and drink, and still being in high school, touching on every stage of life in between at least once.
** Lampshaded in one issue where a [[ActuallyADoombot childhood-obsessed, adult hating]] [[DependingOnTheWriter version]] of the Toyman tells his [[MultipleChoicePast story]] to Jimmy Olsen alone because he doesn't trust anyone over the age of eighteen. Jimmy kicks him over and shouts that he's ''Twenty-Three'' years old exactly.
* ''ComicBook/{{Tintin}}'': It's never made exactly clear how old Tintin is. He is obviously young, but has no problems going round the world and getting into adventures without any mention of parents or the like. We do know that he works as a reporter, but we don't even see him actually performing this job. He does live together with Captain Haddock in his castle, along with Professor Calculus. In response to this, Herge was actually asked to create a character with a family, mum, dad, little sister, pet, etc. in order to have a more "realistic" series of adventures. The result was ''ComicStrip/JoZetteAndJocko'', a fun, but less successful series. As Herge pointed out, it was much harder to keep track of all those characters. At least good old Tintin was unencumbered. Not everyone gets to be an orphan.
* ''ScottPilgrim'' [[LampshadedTrope lampshaded]] this all the time with Ramona Flowers. While every other character would have their age blatantly stated every time they were introduced (especially [[MemeticMutation Knives Chau, Age 17]]), Ramona's introduction was always followed by "Age Unknown." At one point, Scott ''lampshades the lampshading'' when Ramona gets mad at him for not knowing how old she is. He defends himself with, "But your age is unknown!"
* Granted, TheSmurfs are defined as 100 years old, but what makes them an example of the trope is the fact that it's unclear which human age equals that; most of them have specific jobs inside the village, yet they frequently play ball and act immature. Maybe one thing or the other may be the consequence of living in a small village led by their father (Papa Smurf is no mere name -- he raised the 98 Smurfs). They were more clearly defined as adults when three of them were age-reversed to Smurflings, which made the adult Smurfs behave somewhat more mature and proved that [[TropesAreNotBad we were better with the vague age]].
** This gets even more complicated with the appearance of Gutsy Smurf with his [[HotbloodedSideburns sideburns]] in the [[Film/TheSmurfs live-action movie]], since most of his fellow Smurfs don't have facial hair.
* Unlike other versions of the series, ''SonicTheComic'' never stated the age of anyone. Their ages were either left ambiguous or never stated at all. The series goes by its own canon, so we can't assume that most characters fit the game age either. Tails is stuck somewhere between eight years of age and fourteen, while Amy never really did seem to be as young as she was in ''SonicCD'' (which was eight). Sonic and Knuckles can visit bars so they're probably adults.
* Comicbook/DoctorStrange started out somewhere in his fifties, though the standard depiction is of a man somewhere in his mid-forties. Even so, the only real indication of his greater age are some lines on his face and the {{Skunk Stripe}}s of greying hair at his temples.
* The pygmies in ''ComicBook/PocketGod'' may appear to be small children given their size, but most of them don't act like it. They don't even know their own ages or how long they've been around; probably as a side effect of their ResurrectiveImmortality.
* Thanks to her HealingFactor being forcibly activated at the age of ''seven'', ComicBook/{{X 23}}'s age becomes much less clear. She ''looks'' about 17, but because her aging process is slowed by her mutation, [[OlderThanTheyLook she can easily be years older than this]]. However a closer look at the dates given in her various solo appearances does confirm an age of 17 by the time she joins the X-books proper: She escaped the Facility at 13, was 14-15 while staying with her cousin and aunt (which can be verified because Megan was still in high school, and is known to be a couple years older than Laura), and 15-16 during ''NYX''.
* Kitty Pryde is the original example of this in ComicBook/XMen comics. Introduced the TagalongKid of the team, she slowly appeared to age up. This came to a head when Creator/WarrenEllis took the reigns of ''ComicBook/{{Excalibur}}'' and decided he wanted Kitty to be in a relationship with the very much adult Peter Wisdom. This sent the Marvel Offices into a panic because in their minds, Kitty was still a "teenager". Eventually, they found middle ground and decided to [[MayDecemberRomance portray the romance]] as being like "[[Franchise/StarWars Leia and Han Solo]]." Since then, writers have been extremely vague with exactly how old Kitty actually is, especially considering there's been other characters who were introduced as teenagers after Kitty up rapidly aged up to be the same age as her or even older.

[[folder:Eastern Animation]]
* In ''Animation/QumiQumi'', Juga, Yusi, and Shumadan are obviously young, though their personalities can range from being eight-year old children to eighteen-year old teens in various episodes.

[[folder:Fan Works]]
* Most of the main cast of ''FanFic/TheBunker'', In some episodes the gang is shown driving, In some episodes ACF appears in, she looks like a Powerpuff Girl.
* The Agents in ''FanFic/AkatsukiKittenPhoenixCorporationOverhaul'' are implied to be somewhere between mature teenagers and in their twenties. This is muddled by the fact that they don't live in a linear timeline, and some of them simply look older in a relative manner to the others. For instance, Agent Diamond is less than five feet tall (despite her impressive bosom), and is a bit of a PsychopathicManchild, while her boyfriend, Agent Chimera, is six foot three and generally quite mature. All but one of the Agents are stated to have been born within two years of each other.
* Averted in the ''Fanfic/EmpathTheLuckiestSmurf'' series, as Empath and his fellow Smurfs are depicted as being in their early adult stage around 150 years of age, with Homnibus commenting on how young Empath looks for his age.
* In Webcomic/KillLaKillAU, there's this with Ragyo and Soichiro, which would be hard to figure out, as they (then) have three kids who were eleven, nine, and eight and both Ragyo and Soichiro's parents are shown to have grey hair when we first see them, along with being married for at least seven years prior to their divorce, thus at the most they would probably be in their thirties at the least, if not forties at the most. In that vein, we also have Rei, the drunk secretary, although, apparently, she is old enough to drink and can be seen doing so.
* From the [[Fanfic/Gensokyo20XX Gensokyo 20XX series]], there's this with the kids but more explicitly with Yume Ni, An, Maribel, Renko, and an age-regressed Reimu. What is known so far is Yume Ni and An are fairly close in age, with Yu being at least a toddler at the time of An's birth and Reimu being at least in her formative years age-regression wise, with Maribel and Renko being a little unable to say their names correctly, as well speaking more on the level Reimu spoke at. The best estimate for the kids in general would be that their ages are vague, although Reimu and Chen would be older than they are chronologically, as biologically the former's a child, where as chronologically, she would at least in her twenties, and Chen is a youkai definition of a child, as far as that goes.
* We have this with a Anime/KillLaKill fic, titled ''[[https://www.fanfiction.net/s/11037352/1/%E9%A3%9B%E9%B3%A5-Asuka Asuka]]'', particularly, when the titular (who are implied to be either Ryuuko or Satsuki, never made clear which) "Asuka" [[spoiler: dies of her illness]], however, she is described as being "so young" when she was diagnosed and presumably didn't make it to her teens, according to her sister's narration.
-->'''Narrator''': [[spoiler: She would have been eighteen]]

[[folder:Films -- Animated]]
* Mirage from ''WesternAnimation/TheIncredibles''.
* Jack Skellington from ''WesternAnimation/TheNightmareBeforeChristmas''. In personality and voice, he comes across as being in his late twenties or early thirties, but he's an undead skeleton man, so this has no connection whatsoever to how long he's been around, and aside from being adult-sized it's impossible to gauge his age from his looks. He's probably older than thirtyish, though it wouldn't be impossible for him to be younger.
* The video game characters in ''Disney/WreckItRalph''. While all game characters are technically immortal unless they die along with their game or outside of it, Ralph looks to be in his 30s while Felix and Calhoun appear more in their late 20s. Meanwhile, Vanellope and all her racing rivals are supposed to be 9 - 10 years old.
** The games they come from (and by extension, the characters themselves) have different ages. Ralph and Felix have been around for 30 years. Vanellope's game has been around for at least 15 years and Calhoun's game was only installed a week before the events of the movie, making her the youngest character chronologically.

[[folder:Films -- Live-Action]]
* ''Film/IndianaJonesAndTheLastCrusade''. Alison Doody was 22 when the movie was filmed, and while Dr. Elsa Schneider has no onscreen age, she has to be at least thirty.
* Dorothy in ''Film/TheWizardOfOz'' is supposedly meant to be under ten years old, but Creator/JudyGarland couldn't pass for a little kid even with SuppressedMammaries. Most people who watch the movie think Dorothy's meant to be between twelve and fifteen.
* ''Film/ETTheExtraTerrestrial''. According to the novelization of the film he's over 10 million years old. Other sources put him at about 800 years old, and he's shown to be a child in the [[ExpandedUniverse book E.T: The Book of the Green Planet.]]
* Apparently done deliberately in casting Malcolm [=McDowell=] as Alex in ''Film/AClockworkOrange''. The character is revealed to be [[spoiler:fifteen]] in the book, while [=McDowell=] appears to be somewhere in the rage of late teens to early twenties.


* In ''Literature/ABrothersPrice'', the ages of the younger princesses are left vague, we know only that they are not "of age" and still play with toy soldiers, which due to them being RoyalsWhoActuallyDoSomething is not as good a hint on their actual age as it could be - they could deliberately continue to play war with their younger sisters in order to learn about strategy and line of command. There also are some older noblewomen mentioned in the backstory, who are "ancient", but we do not learn their actual age, they could simply have aged badly.
* Vardaman from William Faulkner's ''Literature/AsILayDying'' has no set age, and it is often debated as to whether he is young or just retarded (or both).
* In ''ASeriesOfUnfortunateEvents'', Sunny is [[WiseBeyondTheirYears exceptionally clever for a baby]], and her physical development occurs in a deliberately uneven, contradictory way; for example, even after [[spoiler:she learns to walk]], she is small enough to sleep in a casserole dish. Her exact age is never stated, and flashbacks to "before Sunny" carefully avoid giving the other siblings' ages at the time, forestalling calculation. Averted in book thirteen, which stated Sunny was about three, which would mean she would be about six months at the most in book one, meaning about two and a half years have passed since.
* Everyone in ''TheMoomins'', though some are more vague than others, and especially Snufkin.
* Ascanius, Aeneas's son in the ''Aeneid'', is at varying points in the poem young enough to curl up on Dido's lap at dinner (or at least, no one thinks it's weird when Cupid impersonates him to do so), and old enough to fight in the war. He appears to be somewhere between four and fourteen, never specified.
* Creator/DianaWynneJones deliberately kept the ages of her child-characters vague unless there was a plot reason not to, to broaden their appeal to child readers. At a certain stage it can be off-putting to find out that the hero of the book you're reading is younger than you are (if you're eleven, nine seems pretty young). In ''{{Hexwood}}'', some characters' VagueAge is a plot point in itself.
* This was done in ''Literature/{{Animorphs}}'' to make the characters more relatable to a wider audience (in universe done to protect their identities). This was changed in the last book when it was revealed that they were aged 13 in the first book and 16 in the last.
* In the BookOfGenesis, the story of Isaac's near-sacrifice has him speaking to his father Abraham the way a young child would, asking him, on the way up the mountain, where the sheep was for their burnt offering, and Abraham replying evasively, "God will see to the sheep for his burnt offering, my son," as though to shield him from the horrible truth until the last moment. However, based on the internal chronology of the book, Isaac would've been thirty-seven years old at the time. Thus, the Jewish sages of late antiquity [[ExploitedTrope exploited]] this ambiguity, portraying Isaac as old enough to give informed consent to his own sacrifice.
* Chichi deliberately invokes this in ''Literature/AkataWitch''. She refuses to tell anyone how old she is, except when she's teasing an older man. After she gets him excited, she tells him she's twelve (or whatever age she feels like being), laughs at his horror, and runs off.
* Ozma's age in ''Literature/TheWonderfulWizardOfOz'' is never concrete. Some illustrations have her as an adult, some as a child. Typically she's depicted as being Dorothy's age though.
* In the ''Literature/RainbowMagic'' series, it's never stated how old Rachel and Kirsty are supposed to be. They could be anywhere from very young to middle school aged.
* Professor Cole in ''Literature/{{Murderess}}'', who can transform into a teenage boy and back.
* Literature/{{Coraline}} is hard to pin down. Illustrations make her seem anywhere from 11 to 14 and she's stated several times to be small for her age so she could easily be a teen. Mentally she can be similar to a middle schooler but at other times seems more like an 8 year old. The [[WesternAnimation/{{Coraline}} film]] gices her an age of 11.

[[folder: Live Action TV ]]
* ''Series/ThirtyRock'': Kenneth appears a bit too old to be in the age bracket likely to work as a network intern, but there's also quite a bit of evidence that he might actually be [[OlderThanTheyLook older than he appears]]. No definitive answer has ever been given. Seriously, just check out the OlderThanTheyLook section on the series' main page. If he's to be believed, Kenneth has been working for NBC since '''''[[spoiler:1936]]'''''.
* ''WesternAnimation/BluesClues'': How old are the live action cast supposed to be? Apparently Steve is an adult, maybe a [[DawsonCasting late teenager]], but what about his brother?
* ''Series/{{Community}}'': Abed is somewhere in his twenties, but where is anyone's guess.
* ''Series/{{Merlin}}'': Has never given any definitive ages for its cast, though WordOfGod has it that of the four leads, Morgana is the oldest, followed by Arthur, with Merlin and Guinevere clocking in as late teenagers when the show begins. When taking into account the [[TimeSkip Time Skips]] that occur between seasons, nearly ten years have passed in-show, meaning that the cast (all in their mid-twenties when filming began) went from DawsonCasting to PlayingGertrude.
* ''Series/TheBigBangTheory'': Most of the characters are in their twenties, nobody knows where. Subverted with Howard, who is said to be 26.
* ''TheMuppets'': Most of them, since they tend to have abstract appearances anyway. For ''Series/SesameStreet'' characters, this is done for psychological appeal; the regulars are supposed to emulate different stages of childhood development, and each character's 'official' age is just a reflection of that.
* ''Series/{{Revolution}}'': The characters have not been given ages for the most part. However, Danny Matheson is supposedly 19 years. This is reasonably close the character's actor Creator/GrahamRogers's age, which is 17 years old. Captain Riley is apparently the youngest captain the Monroe Republic has. The actor playing the character Creator/OmidAbtahi is 34 years old.
** Danny Matherson said he was 18, if you take in the fact Neville whom barley know Danny said he was possibly 19, it meant be better to believe Danny.
* ''{{Smallville}}'':
** Lex Luthor has the ability to somehow blend in with high school students.
** Clark himself probably helped. The character of Clark Kent was 15 at the start of the series or close to it, judging by his grade in school, [[DawsonCasting but his actor was 25 at the time]].
* ''TheSuiteLifeOfZackAndCody'':
** In the first season, Zack and Cody are presumably the same age as their actors: 12 or 13, while Maddie and London are in their late teens. However, in later seasons (and in the spinoff), they are clearly older teens, while Maddie and London are the same age: In the spinoff the twins and London go to school together.
** When Zack and Cody graduate in the spinoff, their actors are about 18/19 years old. [[AsianAirhead London]] graduates at the same time, despite originally being a few grades ahead of them, because she kept flunking grades.
* ''Series/TheVampireDiaries'': All of the Originals ages are unknown. Rebekah and Kol are teenagers, where in their teens they fall is anyone's guess and Klaus, Elijah, and Finn are total mystery. It's also unknown at what age Katherine was turned.
* In the seasons of ''Series/PowerRangers'' where the characters are not high school students, the Rangers' ages tend to be left vague at best. They are often provided in promotional materials (for some characters), though even these are notoriously unreliable: Bridge, the only character in ''Series/PowerRangersSPD'' with a definitive age, was listed as 17 on the Jetix website but is explicitly 21 in the show proper.
* ''Series/{{FarScape}}'', for much of its run, which is odd considering how often the show mentions time passing. In the first episode, D'Argo's age is given as 30 cycles (young for a Luxan, which means he married very young - a plot point). Everyone else's age stays mostly vague. Chiana is often stated to be "a kid" compared to the others, and acts as though she's in her late teens/early twenties. John's age can eventually be inferred as about 30 when he joins Moya, since he's old enough to drive in 1986 and was presumably born in 1969 or 1970.
* In ''Series/TrueBlood'', only the vampire characters ever have exact/approximate ages given, usually for dramatic effect like Russell being over 3,000 years old or Jessica being 16 when turned in Season 1. The humans' ages are kept vague, not helped by the show's rather fluid sense of time. Lampshaded by Nicole's mother when she objects to her relationship with Sam:
-->"You are 23 years old! And may I ask how old ''you'' are, silver fox?!" (This becomes her "nickname" for him.)


* ''VideoGame/MapleStory'' allows your character to marry ([[BribingYourWayToVictory For NX, of course]],) even if they look like they're not even close to maturity. Some of the quest givers give off the impression of being young (i.e. a student attending a magic school), but appear to be just as tall as your character and don't have a clear age either. In one quest line, you begin by playing hide and seek with children. A few levels later, you're fighting in a revolution.

* In ''ComicStrip/LittleNemo'', Flip's age is perennial a mystery, referred to at different points as a child and 23, and the same height as Nemo with a receding hairline and cigar.

* Musicals in general tend to have a case of this. Unless it is plot relevant, a character's age will probably be vague enough to allow actors spanning a decade to play them. Possibly more.
* Theatre/{{Hamlet}}. He's a university student, he was passed over as heir when his father died, and the play is more or less his ComingOfAgeStory, all of which would seem to put him in his late teens. But the scene with the gravediggers gives his age as thirty (or thereabouts). The historical explanation is that Hamlet was probably originally intended to be a teenager but that Shakespeare changed his age so his [[ProductionPosse usual star]] Richard Burbage could play the role.

[[folder: Video Games ]]
* It says something that Link's age alone in ''Franchise/TheLegendOfZelda'' has spanned a large FlameWar among fans:
** Early in his series, Link's age was indeterminate, and his sprite had too little detail to tell. In-manual art drew him like Peter Pan with more hair, making it more unclear how old he actually was. The exception is in ''VideoGame/ZeldaIITheAdventureOfLink'', where he is explicitly 16 years old. Most of the later console games give him a more explicit age, but the handheld games are still vague. It wasn't until much later when Link in ''VideoGame/TheLegendOfZeldaI'' was confirmed to be 12 years old from the same source that stated that ''Ocarina of Time'' Link was 9 years old as a child. Link in ''VideoGame/TheLegendOfZeldaALinkToThePast'' may be implied to be a kid, not only by the AV Famicom commercial (which oddly promotes the cartridge port of ''VideoGame/TheLegendOfZeldaI''), but also by the GBA port of the game, where he is given young N64 Link's voice.
** In ''VideoGame/TheLegendOfZeldaTheWindWaker'' Link's age is never mentioned in the game itself, but while [[AllThereInTheManual the official strategy guide]] pins him at twelve, the game itself states that Link starts his quest at the same age that Link from ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' (9 as a child, 16 as an adult). The games that follow ''The Wind Waker'', namely ''VideoGame/TheLegendOfZeldaPhantomHourglass'' and ''VideoGame/TheLegendOfZeldaSpiritTracks'', both made Link look rather young because of his chibi model.
** His age isn't stated, but is generally assumed to be a between 9 and 16 in ''VideoGame/TheLegendOfZeldaMajorasMask'', as he is younger than the 16-year-old model but it is stated to have been a while since the events of ''Ocarina of Time'', at the end of which he stayed 9.
** ''VideoGame/TheLegendOfZeldaTwilightPrincess'' supplemental material confirms his age there as 17. He's the same age in ''VideoGame/TheLegendOfZeldaSkywardSword'', though Miyamoto had suggested during development that he would be even older.
** Zelda herself is an oddity. Her age is never given but she rarely, if ever, seems too different in age than Link. Twilight Princess Zelda is a source of common debate: Is she older than the roughly 16 year old Link or is it simply her stoic and mature personality that gives the impression?
* ''Franchise/SuperMarioBros'':
** Princess Peach. In the games (especially in her 3D appearances) she has a decidedly mature physique and is even taller than Luigi; however, in the comics she acts more like a tomboyish tween, and her relationship with Mario seems to be one of childish infatuation. Also, in ''VideoGame/PaperMarioTheThousandYearDoor'', the Shadow Queen refers to her as a "child" (though the Shadow Queen is a 1000 year old demon and could be using "child" metaphorically). We do get one age confirmation on the DVD extras of the ''[[SuperMarioBrosSuperShow Super Mario Bros. 3]]'' cartoon where she is supposed to be 17 years old. But the cartoon isn't really canon, so the question still remains.
** This also applies to Mario, Luigi and Bowser. In [[VideoGame/MarioAndLuigiPartnersInTime Mario & Luigi: Partners in Time]], we see the three, plus Peach, as infants; yet in their adult years, Peach hasn't lost her youthful look. The Mario brothers are implied to still be in their twenties, and they're just a bit older than her.
*** Mario was confirmed 26 in his Japanese trophy description for ''VideoGame/SuperSmashBrosMelee''. Luigi is his twin brother (but born after him) so he is also 26. Peach and Bowser still remain a mystery, but since Peach couldn't even walk as an infant in ''Partners in Time'' and Bowser could talk as an infant, which the baby Mario Bros. can and can't do, respectively, Peach is implied to be a year or so younger (around 25) and Bowser a year or so older (around 27).
** Yoshi. The official voice was introduced in Yoshi's Story for a group of Yoshi infants, yet in later games, the same voice is used for its grown form. In ''VideoGame/PaperMarioTheThousandYearDoor'', it gets even weirder as the Yoshi there apparently hatches out of the egg with vague knowledge of the world ("Is that one of those 'kiss' things? I've go to get me one of those!") and no name, but talks like a teenage punk and generally acts like an adult.
*** He looked a lot older in his first appearance in ''VideoGame/SuperMarioWorld'', but changed to the Yoshi we see today by ''VideoGame/YoshisIsland''.
*** Yoshi's (the main one's) infant form also appeared as a cameo in the ending of ''Yoshi's Island DS'', making it even ''more'' confusing.
** Kamek. He's presumably pretty old given how he was an adult back in the ''VideoGame/YoshisIsland'' series (and is still around now), but how old? Who knows, he hasn't even changed design in the 20 odd year time skip. Only thing that ever changed for him was the colour of his robe and wizard hat (and by one shade of a blue at that).
** Rosalina. She looks to be in her 20's or ''maybe'' early thirties, but visits the Mushroom Kingdom ''every 100 years''. She is implied to be immortal, but that doesn't explain why she physically appears younger in the optional flashback story.
* The questionable art skills of Zun, ''VideoGame/{{Touhou}}'''s creator have made the intended age of most characters unfathomable from their official portraits. Since WordOfGod stays extremely vague on the subject, this has left the fandom free rein on their age. Even more than the others, [[{{Catgirl}} Orin]] and [[CuteWitch Patchouli]] (who wears baggy clothes) have fallen victims to this trope, alternating between cute girls and fully grown women, DependingOnTheArtist. Even limiting it to the humans, whose ages presumably matter more, it's extremely unclear how old Marisa and Reimu are supposed to be, with the range often being given as things like 10-20. And even if we knew their precise age at one point, it's unclear if they're aging or not. If each change of the seasons indicates a year passing in-story, they'd be somewhere in their 20s by now. Which isn't entirely implausible, but it's just hard to tell.
* Amareus of ''YggdraUnion'' is one of only a handful of characters in the game whose age is not explicitly stated somewhere or other. Instead, the official website gives us a ballpark-estimate quote: She's "2? years old".
* Flora in ''Franchise/ProfessorLayton''. The only clue given for Flora's age is that the events of the first game happened after she was "out of childhood," but she's still young enough to require a guardian; most players estimate her to be between fourteen and seventeen.
* Many in ''Franchise/{{Pokemon}}'', especially the protagonists.
** The only protagonists with a confirmed age is [[VideoGame/PokemonRedAndBlue Red]], who's eleven. [[DistaffCounterpart Leaf]] and [[TheRival Blue]] are presumed to be eleven too. [[VideoGame/PokemonColosseum Wes]] is stated to be around seventeen - eighteen, and a spinoff girl is said to be just a bit older than him.
** The ''VideoGame/PokemonBlackAndWhite'' protagonists are stated to be older than previous heroes of the main series, but it's unknown by how many years.
** Many people assume the player characters are around 10 thanks in part to the anime making Ash 10, but again, the only characters in the games with outright stated ages are a year older than that. Also, Michael is identified as "an unknown teen" in Gale Of Darkness, so he could be at least 13, yet he looks about the same as the characters from the main games (not to mention he's about a head shorter).
** The ''VideoGame/PokemonXAndY'' protags muddy these waters even further; thanks to the VirtualPaperDoll feature of the games, their clothing and hairstyles can make them ''look'' older or younger. On one extreme, "cute" outfits can make them look like the ten-year-olds everyone associates with Ash and Misty (Serena even getting some Misty-like outfit options), while on the other end of the scale, outfits from Snowbelle or Lumiose can make them look like early college students. Even more confusing is that your character has to bend down to talk to young children, but not ''all'' children. The very best we get is that a character who is roughly the protagonists' height is identified as being sixteen. And said character is OlderThanTheyLook and the protagonist is implied to be older than them.
** ''VideoGame/PokemonOmegaRubyAndAlphaSapphire'' averts this with many characters, as the news you see on the Pokenav confirms ages for several characters (for example Wally is 10 and Professor Birch is 35). The protagonists age is still mysteriously absent despite the news discussing them quite often.
* Terra, Aqua and Ven of ''VideoGame/KingdomHeartsBirthBySleep'' are never given official ages, unlike Sora, Riku and Kairi. Though if you take some things into consideration, such as Ventus being physically identical to Roxas (Nobody of fifteen year old Sora) and WordOfGod telling us that [[spoiler: Xemnas is about thirty]], it's not that much of a stretch to assume that Ven is about fifteen and Terra is about nineteen. All we get for Aqua is that she's younger than Terra and older than Ven.
* Maxwell from VideoGame/{{Scribblenauts}} is never given an age, though Scribblenauts Unlimited establishes he's still a kid.
* Your fellow villagers in ''VideoGame/AnimalCrossing'' are... mystifying, to say the least. They live on their own, so they're adults, right? But some of them mention still having allowance, and some of their birthday messages imply they're not yet adults. But there are no parents anywhere (and, in fact, the kangaroo villagers ''have children of their own''). The "Grumpy" villagers act older than the others, with some of their dialogue implying they're probably in their early 30's (they mention not knowing what's popular with kids, but aren't implied to be too much older than the others), but with the rest of the clan, it's anybody's guess. The protagonists are equally vague. You look like a child but are implied to be an adult. The newest game has changed from SuperDeformed to a more lanky style, with mixed results. ''Series/SuperSmashBros 4'' makes it even vaguer as they refer to Villager as a "young man". He doesn't have a voice so you can't tell his tone either.
* Made a plot point in ''VideoGame/GoldenSun: The Lost Age''. After visiting his homeland, where [[ReallySevenHundredYearsOld people age extremely slowly]], the characters start asking Piers about his age. Piers refuses to answer, and gets upset when the others start pressing the issue. He worries on-screen that [[JustifiedTrope knowing his age would change how his new friends see him]] (and it's also possible he's just embarrassed about it). Fans consequently tend to assume he's [[OlderThanTheyLook significantly older]] [[IntergenerationalFriendship than the rest of the cast]], possibly bar [[CoolOldGuy Kraden]].
* Nobody knows how old the villainous Doctor Eggman from ''Franchise/SonicTheHedgehog'' is supposed to be. The only clue about his age is that he was alive when Professor Gerald Robotnik perished 50 years ago, implying he must be at least that old.
* Characters from ''VideoGame/ParappaTheRapper''. For an example, Parappa himself is old enough to drive a car and join the military but not old enough to work.
* Kirby was described in the [[AllInTheManual Manual]] of Kirby's Dreamland to be a "little boy" but gave no age, and his age in games since then hasn't really been touched upon.
* Some of the characters in the ''VideoGame/WarioWare'' series fall into this. Ashley's the most obvious example (her 'official' age is supposedly around 15 according to the US website, but might be different in Japan), and her design is so vague that it's kind of hard to tell what age the character is outside of 'looks fairly young'. Same deal with 18 Volt, who looks like anything between a high school student and adult, who's somehow still in elementary school.
* ''VideoGame/DontStarve'': Willow. [[PsychopathicManchild Psychopathic Womanchild]], or EnfantTerrible? The art style makes it hard to tell how old she is, though WordOfGod says that she's the same age as Wilson, who's at least old enough to grow a beard.
* The cast of ''VideoGame/HarvestMoon'' games tend to be this.
** One of the few games where all of the characters have defined ages is the "[[VideoGame/HarvestMoonAWonderfulLife Forget-Me-Not Valley]]" series of games (''A[nother] Wonderful Life, DS [Cute]''), where [[AllThereInTheManual the manual]] gives the characters' ages. This can be especially confusing given that there are certain characters who state that they're older than the protagonist, [[MayDecemberRomance especially when they're romanced]], but who look exactly the same as everyone else due to [[PuniPlush the cutesy art style.]] A prime example is Muffy, who is in her early thirties but looks as sweet and cutesy as the other girls.
** Luna in ''Tree of Tranquility'' is so short she resembles the other children on the island, but is of marriageable age. This naturally caused a bit of {{Squick}}, so in ''Animal Parade,'' she got a height boost. She's still on the younger side, especially in [[ElegantGothicLolita the way she dresses]], but how ''much'' so still isn't clear.
** Calvin from ''Tree of Tranquility/Animal Parade'' is an especially confusing case. When romanced, he alludes to there being an age difference between him and the protagonist. However, his character profile explicitly refers to him as a ''young'' man. Either the protagonist is really, really young, or she's [[OlderThanTheyLook older than she looks.]]
** Soseki from ''A New Beginning'' is another odd case. He also alludes to being decently older than the protagonist. However, most of the other SilverFox bachelors in the series had AnimationAnatomyAging to indicate them being older--Soseki doesn't. This leads to the common fan theory that he's not that old at all, but he's ''extremely'' self-conscious about it. [[{{Hypochondria}} It wouldn't be out of character.]]
* In ''VideoGame/EndlessOcean: Blue World'', nobody's age is pinned down, but of note are Professor Sakurai, who is said by Oceana to be "too young" to have done all she's done; Oceana herself, who, at least in the NA version, has to be at least 15 since her father's accident is stated to have been 15 years ago, and is more likely to be 17 or so, as she was "very young" at the time rather than "not born" or "just a baby"; and the player character, who joins the diving service while taking a break from courses.
* Usually this isn't an issue with main characters in the ''Franchise/TalesSeries'', but Judas's age is a problem. [[spoiler: Leon was 16 when he died]], and Judas still looks young, but [[spoiler: considering he was revived at some undetermined point between the Eye of Atamoni incident and the present]] in ''VideoGame/TalesOfDestiny2'', and he's treated like the old guy of the group, he could be anywhere from 16 to 34.
* ''Franchise/SpyroTheDragon'' is a KidHero but how old he is is never specified. Considering the fact [[VideoGame/SpyroYearOfTheDragon dragon eggs only hatch once every twelve years]] he could be twelve however we don't know how dragons age.

[[folder: Web Comics ]]

* The characters in ''Webcomic/WhatTheFu'' are only defined as somewhere in their twenties, mostly because [[UnreliableNarrator Zac]] can't be bothered with details.
* In ''Webcomic/CityOfReality'', none of the main characters have defined ages -- this is deliberate on the part of the author so as not to trip himself up with potential romantic subplots. The cartoonish art style doesn't help matters. However, it is possible to extrapolate from their statements about graduating high school and the assumptions people on other worlds make about their youth, and they got a visual (though again not textual) age-up between chapters 5 and 6.
* Cucumber and his sister Almond of ''Webcomic/CucumberQuest'' are, in the author's own words, "A young kid and a slightly younger kid." We do know that Cucumber isn't 9, because that's how old his father thinks he is.
* ''Webcomic/{{Sinfest}}'' is pretty weird with this. Word Of God is that Slick is somewhere between 14 and his early twenties, and the other characters rarely (if ever) get their ages touched upon. It's especially weird considering that most of the main male characters look considerably younger than the women (who all look somewhere from their late teens to twenties). It's not helped by the fact that just about every character lives on their own.
* ''Webcomic/TheDragonDoctors'' has this as a deliberate, in-universe social issue due to the fact that society has access to a functioning FountainOfYouth.
* The author of ''Webcomic/SchlockMercenary'' has confessed that he has no idea how old General Tagon is, guessing that he's somewhere between 18 and 40 years older than his 49 year-old son.

[[folder: Web Original ]]

* ''WebAnimation/HappyTreeFriends'': According to the creators, the Tree Friends are whatever age is necessary for the cartoon to work, aside from a handful of characters who are always portrayed as adults (though rarely competent).
* ''WebAnimation/HomestarRunner'' has only two or three confirmed "adult" regulars; the others can be, as the plot requires, young enough to be going to preschool or old enough to be drinking Cold Ones. Even the adult regulars aren't too old to play spaceman with tin foil outfits and cardboard spaceships. Don't even ask about Homsar.
** [[http://hrwiki.org/wiki/Ages_of_Characters This Page]] on [[TheWikiRule the wiki]] attempts to clear things up a bit. Emphasis on "a bit".
* The flash cartoon series ''WebAnimation/RetardedAnimalBabies'' has mocked this a few times. Despite the name "Babies" the character Bunny claims to have gone to high school and even had several wives (to which the character Puppy says, "Shit man, how old are you?").
* In ''DarwinsSoldiers'' this trope is made explicit by Ariol, Kain, Subject 19, Siren, Breathtaker and Stalker; all have their age listed in their profiles as "unknown".
* Most of the cast of GaiaOnline qualifies, especially since the website ''does'' acknowledge the passing of years and the characters do have birthdays. They just don't resemble their alleged ages. At all.
* The Trapezoid Kids are deliberately drawn so that they need their TertiarySexualCharacteristics, exaggerated gestures, outer body colors, and voices for anyone to even ''tell them apart'', much less know exactly how old they are. [[TheBlank They aren't even drawn with visible faces]].
* The bikes in ''When Bikes Argue'' could be literally any age. But [[ArtisticAge only Betsy is described specifically as a child]]. The other bikes are allegedly between 20 and 50, in keeping with who might be riding them.
* Spoofed in ''WebAnimation/BarbieLifeInTheDreamhouse'', where ''nobody'' knows what Barbie's age is, not even her closest friends.
-->'''Teresa:''' She ran for President once! You have to be ''at least'' thirty-five for that, so let's see... CarryTheOne... uh... What am I adding?

-->'''Barbie:''' Today, I'm officially [[spoiler: ''[[TheUnreveal (gets drawn out by the vacuum)]]'']]
* [[http://tokiandcowiki.wikidot.com/wiki:toki Toki]] and her twin sister [[http://tokiandcowiki.wikidot.com/wiki:doki Doki]] are older than they appear but how old they are is never stated, though, going by ''Doki's Chronicles'', they should be about either in their late eighties to early nineties, as the setting of one of the stories was in the nineteen twenties to thirties and their [[http://akaichounokoe.deviantart.com/art/What-Toki-normally-thinks-about-319433086 clothing]] from that point in time seems to suggest about that.
** There is also [[http://tokiandcowiki.wikidot.com/wiki:eglantine-rabbitwright Eglantine]] and presumably she is a toddler, as she is still in diapers and young enough to attend nursery school, though, if the passage of time is to go by, she should be four if not five and what is known is that she still a young child. Justified, in this case as no one has no clue as to how old Eglantine is because they don't know her birthday, thus they wouldn't know the year in which she was born in.
** [[http://tokiandcowiki.wikidot.com/wiki:brownie Brownie]]is stated to be "likely to be in early to mid twenties" though she was about twelve or thirteen when she met Toki, making that a tad more appropriate.
** [[http://tokiandcowiki.wikidot.com/wiki:magnolia-rabbitwright Magnolia]] is stated to be about 2-4
** There's [[http://akaichounokoe.deviantart.com/art/Killerbunnies-XI-and-XII-Kamu-and-Kanran-444451527 Killerbunnies XI and XII: Kamu and Kanran]] who has a condition that makes them look like babies but they don't seem to let them stop them in being damn near malicious and that both are old enough to smoke but their ages are never stated. In that vein, we have Jeanne and it hard to pinpoint how old she is or whether or not she is even a child or through some means or another just looks like one.
* Couette from ''Franchise/{{Noob}}''. She's [[TeensAreShort short]] and acts like a stereotypical teenage girl, but is also the DistaffCounterpart of the franchise ManChild undergoing DivergentCharacterEvolution. Her actress in the webseries is a short adult, but she also hints to still be going to class in some of her dialogue. The comic shows the other contestants at her beauty pageant to be much taller than her and that she lives in her own house, but has her drawn with the same standards as the ManChild in question, making look her like the youngest of all regular players.
* Cecil from WelcomeToNightVale, to go along with his [[TheVoice ambiguous appearance]] and [[AmbiguouslyHuman questionable status as a human]]. His childhood friend claimed to have been a teenager for decades at one point and when questioned [[spoiler: it is revealed that Cecil can't actually remember what year they graduated. And considering they both sound around the same age, that only raises more questions]]


[[folder: Western Animation ]]

* The ''WesternAnimation/{{Histeria}}'' Kid Chorus is stated to be in middle school (even the clearly teenage Toast and Pepper), but their exact ages are never stated (except for Froggo, who's ten).
* According to WordOfGod, the ages of the main characters of ''WesternAnimation/JimmyTwoShoes'' are purposely left vague in order to allow a bigger range of stories. [[EnfantTerrible Heloise]] looks like a little girl, but holds down a job as Misery Inc's top inventor, and all three live without parental supervision. Beezy can still get grounded and gets an allowance, but is old enough to [[ArrangedMarriage get married]].
* Shego of ''WesternAnimation/KimPossible'' apparently has a degree in teaching but (when she's not committing crimes ForTheEvulz) acts like a teenager, lounging around the SupervillainLair reading fashion magazines. Her relationship with [[MadScientist Dr. Drakken]] (who is Kim's father's age) flipped between father-daughter and romantic, even though she had a one-episode romance with Senor Senior Junior, who is apparently young enough to crush on Kim and date her high-school rival [[AlphaBitch Bonnie]].
** In an episode when Shego was mind-altered to be nice, Kim referred to her as a "big sister", marking her clearly as a technical adult. Shego is probably in her mid-to-late 20s, for having a 27-year-old attracted to both a 22-year-old Junior (she acted like "the older woman" to Junior in that episode) and a 41-year-old Drakken would not be uncommon in real life, agewise. WordOfGod is that she was in her mid-20s by the end of the show, so basically between 24 and 26.
** The ages of Kim and Ron (and by extension, their fellow students) are also never really addressed beyond WordOfGod describing them as "high school age". Although given a few details throughout the series (moving to senior year, being able to drive, graduating etc.) it can be reasonably assumed that they start out in the series at 14/15, before ending up at 17/18 in the final season.
* MickeyMouse and friends. Even in some merchandise where they are shown as ''school students'', they still look the same.
* The eponymous {{WesternAnimation/SpongeBob SquarePants}}. [=SpongeBob=] acts like a kid and is even called one, but lives in his own house, has a job, and is old enough to go to "boating school." It is mentioned several times throughout the show that he is an adult.
*** Actually, it was stated on his driver's license in the episode "Sleepy Time" that he was born on July 14, 1986, which would place him currently at about 28.
* The title characters of ''WesternAnimation/PhineasAndFerb,'' as well as their same-age friends, were originally supposed to be nine years (as mentioned in the pilot), but when the creators saw how well various age groups responded to them they decided they were simply "less than fifteen" (their older sister's age). It's hard to get any clearer an example from how they act: Phineas is a CheerfulChild who's ObliviousToLove, while Ferb sounds like a teenager and has hints of being a CovertPervert.
** This also makes it hard to figure out if [[PrecociousCrush Ferb/Vanessa]] is just slightly improbable (two years isn't that big a deal!) or potentially [[{{Shotacon}} pedophilic]] (a sixteen-year-old can't date someone who's ''nine!'')
* In his earliest cartoons, Porky Pig fluctuated between being a child and a [[DepartmentofRedundancyDepartment fully-grown adult]], the later easier to relate to from his future mild-mannered personality compared to other ''WesternAnimation/LooneyTunes'' characters.
* The main characters of its successor, ''WesternAnimation/TinyToonAdventures'', go to Acme Looniversity, which is likely to be a high school (they have a prom, the kids go on spring break, but they still live at home and expected to obey their parents' rules). However Elmyra doesn't look or act like a teenager, and how old the toons actually are is never stated. Some fans assume they are 13, because an episode is called "13something", unaware that the title was a pun (referring to [[PunnyName the sitcom 30something.]])
* In ''WesternAnimation/TheRaccoons'', Bert acts like a child, but he also seemed to have graduated school and works as both a professional journalist and paperboy.
* Spike in ''WesternAnimation/TheTransformers'' - when he first appeared, he was working on an oil rig, but in a later episode, he mentioned he was too young for a driver's license. In the same episode, he ''begins a romance with a girl who is in college.''
* WordOfGod says that RubyGloom is in her early twenties, but you'd ''never'' guess that from just watching the show.
** Several official sources also state Ruby is ''five'', though she doesn't really seem that young to most.
* ''WesternAnimation/KaBlam'': Henry and June's ages are never stated in the show, but appearance wise, most likely nine to eleven, most fans put them at ten.
* The titular character of ''WesternAnimation/FlipTheFrog'' has a different age in different episodes. Sometimes he's portrayed as a kid, sometimes as an adult.
* The members of Dethklok on ''WesternAnimation/{{Metalocalypse}}'' are of a vague adult age. In the first season, Pickles is said to have run away from home 15 years ago at the age of 16, which makes him 31. However, he also played in a hair metal band in TheEighties. If he was, say, 19 in 1985, that makes him 40 when the series begins.
* Warner Brothers didn't want the writers to give Bruce Wayne an established age when he and Terry were celebrating his birth in the ''WesternAnimation/BatmanBeyond'' episode "Out of the Past". They said in the commentary that he would have been around mid to late eighties.
* Who knows how old any of the penguins in ''WesternAnimation/ThePenguinsOfMadagascar'' are? It's worth noting that apparently Private is younger than the rest (but interestingly had at least one earlier identity as the Mini Golf champion Mr. Tux). We're given a clue that Skipper and company weren't alive, or at least were not yet adults, in the 1960s as Skipper wants to go back in time and slap a hippie. It's also worth noting that Buck Rockgut had been down in the tunnel under the zoo for forty-seven years when the penguins found him, and that it's implied that he's much older than they are. That's around twice a normal penguin's natural lifespan.
* ''WesternAnimation/ScoobyDoo'': The Gang are this incarnate. They're old enough to travel on the road on a consistent basis but still young enough to be considered "Meddling Kids." This would seem to imply that they're in the early 20's. Some episodes of the original series seem to place them in high school.
** WordOfGod has Velma (the youngest) at fourteen in the original series and the oldest two being eighteen. In newer series they seem to have aged into their early twenties though, with some direct-to-VHS movies having them in their late 20s. However, in ''ScoobyDooMysteryInc'' they're all explicitly still in high school, and though Shaggy and Velma's exact ages aren't specified Daphne and Fred are both stated to be Seniors.
* Similarly, ''WesternAnimation/TheAmazingChanAndTheChanClan'' places the older kids in their teens and Flip in his preteens. Only the three youngest are given actual ages in canon.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** The main cast seem to show whatever level of maturity is required to make this episode's plot work. They all live independently and most work professionally, but also often act like teens (with things like slumber parties). Their interactions with explicitly pre-adolescent characters seems to vacillate between slightly older sibling to responsible adult figure. It's complicated even further by one minor who apparently has an explicit "teen as distinct from adult" stage. The only hard numbers that exist on ''any'' characters' ages are that Celestia, Luna, and Discord are well over a thousand years old, Sweetie Belle looked significantly younger during a flashback to when she was five years old, and Fluttershy is a year older than Pinkie. And then there's Spike...
** The mane cast's age was given in one episode by showing Applejack as a baby at the Apple reunions (held every 100 months, with the reunion in the third season), leading to a large in-fandom argument about whether the ponies are 17 or 25. Their maturity level indicates the lower number, while their roles in society clearly requires the older, especially as that would require three of the main 6 to be business owners at 15.
** Popular fanon {{HandWave}}s include the possibility that ponies mature faster than humans, or that Equestria's year doesn't directly correspond to our own; heaven knows [[PaintingTheFrostOnWindows the rest of their natural laws don't]].
** EquestriaGirls generally seems to hint that the Mane 6 are 17, as this was Twilight's age when she went to the human world. However, many child characters were age lifted to be freshmen as well. To make it even more complicated, Sunset Shimmer (confirmed in the comics to be older than Twilight by a fair margin) seems to be the same age when they become human.
** The birth-iversary cake in "Pinkie Pride" seems to suggest that a) Rainbow Dash is 21, b) Rainbow Dash is 31 (if the candles go all the way around the tiers, or c) the decorator(s) just like(s) putting candles on a cake without regard for representing years by them.
** Spike, who is several years younger than the rest of the main cast but apparently ''older'' than the other children in the show. He lives with Twilight Sparkle and basically acts as her younger brother, but unlike the other younger characters he can be left on his own for long periods of time (even taking over another's duties), and, rather than going to school, has a job as Twilight's assistant. All the while still being considered a "baby" dragon.
** Throughout the series itself ''Franchise/MyLittlePony'' has fit this. Characters are explicitly referred to as adults and several of them even have children, however they're notoriously immature and love playing with toys. Then again they ''are'' horses.
** Ponies in general are hard to pin down in terms of age. The ones you might assume are all about the some age when in the present day may be either adults ''or'' foals in flashbacks. There are even characters who are adults in pre-Rainboom events such as the Summer Sun Celebration that inspired Twilight Sparkle to study magic, but fillies in post-Rainboom events such as the party that inspired Cheese Sandwich to become a party pony.
* Most of the time DonaldDuck is portrayed as an adult, however one short "Donald's Better Self" depicts him as a child.
* ''Franchise/AlvinAndTheChipmunks'' have cycled between being elementary school age kids, middle school kids, and high schoolers.
* BettyBoop appears to be an adult or young adult, but in "MinnieTheMoocher" we see her running away from home because her parents grounded her when she didn't eat her peas.
* How old Piglet in the Disney versions of ''Franchise/WinnieThePooh'' is never specified. His name and the fact Tigger often refers to him by childish nicknames should mean he's young, but his voice and mature personality make him seem the same age as the others.
* HBO Family sometime airs a show in the vein of ''WesternAnimation/DoraTheExplorer'' called ''El Perro Y El Gato''. The two protagonists seem like adults but in one episode the dog asks the cat what he wants to be when he grows up, and the dog says he wants to be a veterinarian.
* Gwizdo of ''WesternAnimation/DragonHunters''. In TheMovie (which was a prequel to the series) he's established as a homeless adult; in the series he lives in an inn and has apparently been staying there since the innkeeper's daughter Zoria (who is around 18 now) was a child, which would mean that he's quite old. Yet appearance-wise he barely looks over 20 and in "The Isle of Mist" [[spoiler: when he ends up in a FountainOfYouth for a few seconds he immediately reverts to a young child even though the monks before him had to bathe in it for several minutes just to revert to their thirties]].
* Jimbo, Dolph, and Kearney from ''WesternAnimation/TheSimpsons''. They are implied to be teenagers, but apparently attend Springfield Elementary. Kearney on the other hand, while he has a very screechy voice and acts like a teenage bully, he also has a ''son'' of his own, is divorced and according to Otto, they were in [[HeldBackInSchool 3rd grade together]].
** Kearney, oddly enough, was shown in an early episode trying to buy beer with a fake ID and assumed name. Later, he's shown to remember Watergate and is also able to openly go for a drink at Moe's. Of course, the first incident was before they decided that his advanced age and apparent multiple failures to complete the sixth grade were a RunningGag.
** Also, one episode shows that Jimbo is ''bald'' under his knit cap.
* ''WesternAnimation/BeverlyHillsTeens'':
** Chester [=McTech=] is younger than most of the cast, but by how much is never specified.
** Whilshire looks like a teenager like the rest of the cast, but he's almost never seen attending school with them and apparently has a full time job as a valet/chauffeur. This was most likely done to make his crush on the obviously teenage Bianca less {{squick}}y.
* It's hard to pin an age onto the ''StrawberryShortcake'' characters. They look like preteens both in their 2003 and 2007 designs, despite the fact Apple Dumplin' aged noticeably at least six years. It's made even more confusing by the fact the later episodes involve the characters getting jobs, moving out, and driving cars. The 2009 is equally bad, with the characters owning their own stores but looking no older than fifteen. Even prior to this, they lived in their homes, planned their own sleepovers, and otherwise generally managed their own lives and there were no parent characters shown.
** In "Baby Takes the Cake" from the 2003 series, Strawberry Shortcake [[BreakingTheFourthWall warns viewers]] to leave certain dangerous things related to cooking like using knives or handling a hot stove to an adult. Which would seem to be her way of suggesting that she is one.
* Ami and Yumi from "WesternAnimation/HiHiPuffyAmiYumi"', they are assumed to be adults like their real life counterparts but the art style makes them look like children and they act like teens.
* The ''WesternAnimation/{{Popeye}}'' character don't have their ages revealed, though "Goonland" and "Popeye, the Ace of Space" imply that Popeye himself is around 40, while "The Man on the Flying Trapeze" has Olive being called "a maid in her teens". Also in "Puttin' on the Act" (from 1940), it's shown that Popeye and Olive had an 1890s vaudeville act.
* ''WesternAnimation/TotalDrama'' has a mild example with [[DramaQueen Blaineley]], who's clearly supposed to be an adult, but winds up competing in the show with teenagers. She gets ShipTease with both adult [[ScaryBlackMan Chef]] and teenage [[BigFun Owen]], and admits to having a crush on [[InformedAttractiveness Justin]].
* In ''WesternAnimation/TheBeatles'' cartoon, the Fab Four themselves are in their moptop-era designs, meaning they're meant to be very young adults. However, a few episodes have them refer to themselves as teenagers, and yet another episode has them at a legal drinking age.
* It's never stated how old the human main characters of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' are supposed to be, and their school seems to combine elements of elementary school and junior high.
* The chalk drawing characters in ''WesternAnimation/ChalkZone'' are technically as old as when they were first drawn (for example, Snap turns two in "Lost in Chalk" because it marked two years since Rudy first drew him), but most of their physical/mental ages are still left vague. While Snap lives on his own and has been shown driving in a few episodes, he appears to be around eight to ten physically and mentally.
* The fairies in ''WesternAnimation/TheFairlyOddParents'' are immortal and have been alive for millions of years, however it's unsure how old most of the characters are in "human" terms, as well as physically and mentally. Also, Tootie's age seems to be a bit debated. In one tie-in book from 2004, she's stated to be eight (making her two years younger than Timmy). However in some material, she's stated to be ten.
* While most of the characters on ''WesternAnimation/{{Recess}}'' are given ages, what age Cornchip Girl is and what grade she's in was left ambiguous. In "One Stayed Clean" she's shown among the kindergarteners, though this may have been accidental as she was shown running away from them earlier. Most episodes suggest she's in between grades first and third, but has been confirmed not to be in the same grade as the main six. Most fans tend to place her around seven.
* On ''WesternAnimation/{{Maisy}}'' the characters, a cute female mouse and her friends, go where they want, do what they want, [[UniversalDriversLicense drive cars, fly planes]], take their own baths, etc. Really, there's nothing explicitly indicating that they aren't adults, other than their very childlike appearance, childlike babble speech and tendency to play with toys and stuffed animals (not that adults don't ever do that last one, of course.)

[[folder:Real Life]]
* If you're the type of person who doesn't ask people for their age, this is [[InvokedTrope bound]] to happen.
* Charo. She was born January 15 of either 1941 (what her birth certificate says), 1945 (what TheOtherWiki says) or 1951 (what she says).
* Both Music/{{BlueStahli}} and Music/{{Celldweller}}. Due to the fact that they never mention their age nor are their ages listed on any website.
** Klayton is, however, [[http://www.metal-archives.com/artists/Klayton/163527 rumored]] to be [[OlderThanTheyLook 50, of all ages]], but he has [[https://www.facebook.com/celldweller/posts/10151024436601672 denied]] said fact, but whether or not he's being honest is up to debate.
* [[Film/TheRoom Tommy Wiseau]] is famously secretive about his age. In 2010, he claimed to be 41, but other sources list his birth year as 1955, which would make him 58 or 59 as of 2014.
* The author Sydney, Lady Morgan was very vague about her age, maintaining that she was born in 1785 when it was probably 1781. Her death certificate (in 1859) gives her age as "about 80".
* UsefulNotes/IdiAmin's birth date is unknown, guessed at maybe 1923, 1925 or 1928.
