{{Hammerspace}} is a convenient place for characters to carry around mallets, anvils, fridges, or [[CrazyPrepared whatever else they need to advance the plot]] in a very small space. But what do you use to store a whole person?

This trope occurs when whole characters manage to hide themselves away into incredibly small spaces. It could be inside a shoe, or a suitcase, a jewelry box, in a friend's pocket, or [[BehindAStick behind a telephone pole]].

Where ever the hideaway is, it must be an area so small that even if the character were to scrunch up and get squeezed into the space, it would still be too small for them, making Hammerspace the only plausible explanation for how they could possibly fit.

When characters use Hammerspace to disappear behind narrow poles, they are BehindAStick. If a character turns out to be living inside a Hammerspace Hideaway, then it is probably a ClownCarBase instead. If we can see inside the Hammerspace Hideaway, then it will likely be BiggerOnTheInside. Compare PartyInMyPocket. See BehindTheBlack for similar situations resulting from the RuleOfPerception.

* In ''Anime/GirlsUndPanzer'', Rabbit Team takes it UpToEleven by hidding a ''M3 Lee medium tank'' behind a streetsign's post (from the rival team: [[RuleOfFunny the viewer can see them plainly]]).
* In ''Manga/MahouSenseiNegima'', Kaede's Artefact is a cloak (essentially a flat piece of tattered cloth) that can hide several people inside... it does have a fully furnished house in there after all.
* In ''Manga/OnePiece'', due to eating the Castle-Castle fruit, Capone Bege has the ability to miniaturize things to fit within his body (the inside of which is an actual castle).
* In ''Anime/KiddyGrade'', Armbrust's Black Box has extradimensional capabilities and can change shape to allow larger things in and out; several times, this has included people.

[[folder: Comic Books]]
* ComicBook/ScottPilgrim can fit inside Ramona's shoulder purse, because it [[BagOfHolding contains a gate to Hyperspace]].
* Snoopy's doghouse in ''ComicStrip/{{Peanuts}}'':
** Although he always sleeps on top of it, it's clearly much bigger inside than its appearance would suggest, containing a pool table, television, and according to one strip, a sizable book collection. (He even had a Van Gogh in there until his doghouse was destroyed in a fire, but he quickly replaced it with an Andrew Wyeth. Just how he got them was never explained.)[[note]]According to the official Wiki, a full list of Snoopy's belongings kept in the doghouse include A TV antenna, a color TV set, a birdhouse, a recreation room, an air-conditioning unit with extra door, space for seven children, a guest room, a pipe and deerstalker hat, a basement, a den, a closet with a faulty latch, a clock radio, an electrical outlet, carpeting, the Van Gogh painting, (replaced by the Andrew Wyeth), a pool table, a stairway, boxes of empty soda bottles, more closets, flooring, counter tops, a library with fluorescent lights, a ceiling mural painted by Linus, a ping pong table, a potted philodendron, a basketball hoop and net, a shower, silver candlesticks, a grandfather clock, a cedar closet, books, LP records, a pair of pinking shears, ceramic tiles, a stairway, a set of dominoes, a photo album of every supper dish that Snoopy has owned, a postage meter, a servant's entrance, a teakettle, a picture of Tiny Tim, a stereo, a stained-glass window, a carpeted front hall, a bottle of cologne, a waffle iron, a supply of TV dinners, electric socks, a formal suit for a turn-about dance, a whirlpool bath, a downstairs refrigerator, a CB radio, an automatic door, a fishing pole, a hat for wearing whilst fishing, wading boots and bunk beds.[[/note]]
** The interior of the doghouse was seen in the (likely non-canon) animated special ''It's Magic Charlie Brown'', where visible rooms included one with exercise equipment, sports equipment, lockers, awards and trophies; and a lab with a bunsen burner, flasks and distillation equipment.
* Superman has his Fortress of Solitude, In the Aliens vs Predator vs Batman and Superman crossover his fortress is the size of a 5m diameter ball on the outside that houses another universe he can build up on the inside giving him pretty much infinite space.

* There is that addition to the good ship Gay in the Creator/RobertAHeinlein novel ''Literature/TheNumberOfTheBeast''.
* [[spoiler: The real Mad-Eye Moody]] in ''Literature/HarryPotter and the Goblet of Fire'' is stored in one of these.
* Chiron's SuperWheelChair in ''Literature/PercyJacksonAndTheOlympians'', where he hides his [[OurCentaursAreDifferent horse legs]].
* Not the most extreme example, but in the first book of ''Literature/TheMysteriousBenedictSociety'' trilogy, Reynie, Kate, Sticky, and Constance are forced to squeeze into a very small crate to hide from Mr. Curtain. The illustration does not at all look comfy.
* The ''Literature/{{Fablehaven}}'' series has the transdimensional backpack with a storage room inside.
* The wizards of Unseen University in the ''Discworld'' have been trying to study and define Hammer space.Only they don't call it that; they deal with the Cabinet of Curiosities and have frequently witnessed the impossible and potentially limitless space represented by the Luggage. In both cases, Professor Ponder Stibbons is the man tasked with findibg a scientific, or at least a plausibly pseudoscientific, reason why.

[[folder: Live Action Television]]
* ''Series/WizardsOfWaverlyPlace'': Alex invoked this to sneak Harper onto the [[Series/TheSuiteLifeOfZackAndCody S.S. Tipton]] by hiding her away in her suitcase. Justified in that the suitcase is [[AWizardDidIt magic]].
* There was once an episode of ''Series/{{Scrubs}}'' where Turk sneaked JD around in his backpack.
* One common gag in ''Series/ShakeItUp'' involves cute kid Flynn stowing away in his sister [=CeCe=]'s suitcase, even when it's filled to capacity.
** In the ''Series/GoodLuckCharlie'' crossover episode, Flynn, along with Rocky, CeCe, and Deuce, all stowed away in Teddy's luggage. Rocky and CeCe hid in her suitcase, Flynn hid in her carry-on, and Deuce hid in her ''purse''. Yeah, ''her purse''.
* ''Series/{{Danger 5}}'' reveals Stalin's moustache is one of these. [[http://www.youtube.com/watch?v=-e7z9X1YfGU Seen here]]. The gag is later repeated with the DodgyToupee of the President of the World.
* Oscar's trash can on ''Series/SesameStreet'' is clearly BiggerOnTheInside; various episodes show it contains a garden, swimming pool, ice-rink, bowling alley, a piano, Oscar's pet elephant, and of course, lots of trash. Despite this, the trash can still be picked up and carried, usually by his friend Bruno the Trashman.

[[folder:Tabletop Games]]
* Several types of TabletopGame/{{Exalted}} have access to Charms that allow them to store objects Elsewhere. Lunars, however, can actually learn Charms that allow them to create tiny little dens in Elsewhere, safe places they can escape to on a moment's notice.
* ''TabletopGame/DungeonsAndDragons'' examples:
** The Rope Trick spell in several editions of allows the caster and several friends to, well, climb up a rope and "vanish" into a small extradimensional space at the top that nonetheless will hold several people and potentially even allow them to pull up the rope after them as well, making for a quite safe retreat primarily limited by the spell's duration. It's even fairly low-level.
** Other examples include Leomund's Tiny Hut, which creates a dwelling the size of a tent that an adventuring party can sleep in (providing heat and protection from the elements) and the most powerful version, Mordenkainen's Magnificent Mansion, which is an entire house created in an extradimensional space, usually used by wizards to conduct experiments in private. It includes Unseen Servants to help him, and also creates food. The downside is, the food isn't real, and anyone who lives on it while inside becomes incredibly hungry upon leaving, and has to eat immediately afterwards. (At least one module centered upon a wizard who was well-known for being a BigEater because he secretly used this spell very frequently.)
** A famous example is the [[ArtifactOfDoom notorious artifact]] Baba Yaga's Hut. It appears as a small, thatched hut with large legs resembling those of a giant chicken, and is usually dancing when found (indeed, whether it can be better described as a "magical item" or a "magical creature" is debatable). If a wizard of considerable skill convinces it to obey and enters it, it proves ''far'' bigger on the inside, being a rather large palace, with lavishly furnished bedchambers, banquet halls, an alchemy lab, a complete library, and even an observatory. One peculiar thing about the place is that while many of the interior rooms have windows, all of them offer the same view, that from the two windows on the front of the Hut that can be seen from outside. (One source suggests that the Hut has a hidden brain within it somewhere, and destroying it is the only way to destroy the Hut; likely, this is something that only Baba Yaga herself, it's true owner, knows the location of. ''All'' sources hint that the Hut likely has secrets known only to her, and the GameMaster is not recommended to introduce the Hut into a campaign unless he is also willing to introduce her as a villain. The Hut is her home, and sooner or later, she will come to get it back.)

[[folder: Video Games]]
* In ''VideoGame/TheLegendOfZeldaMajorasMask'', the Deku Princess somehow gets put into one of Link's bottles, despite being normally almost as tall as Link himself. Though talking with her after taking her back home has her remark that it was uncomfortably cramped.
* In Episode 2 of ''VideoGame/KingsQuest2015'', Graham and one of the villagers run into a dragon and he hides them inside his [[BagOfHolding Cloak of Holding]]. When he tells his friend [[ARareSentence "Get in my cape!"]], Amaya and Bramble will both react as if it's the dumbest thing they've ever heard, but Chester Hobblepot loves the idea.

* In Webcomic/ThePrincessPlanet, Roger at one point disguises himself as a magical tiara. Normal sized, and complete with actually being put on.
* In Webcomic/{{xkcd}}, one of the many neat things about Black Hat Guy's hat is that [[http://xkcd.com/412/ he can fit himself entirely inside it]].

[[folder:Web Animation]]
* In the WebAnimation/HomestarRunner cartoons [[SpellMyNameWithAThe The Cheat]] lives in TheKingOfTown's grill, which apparently contains a full-sized house.

[[folder: Western Animation]]
* ''WesternAnimation/SpongeBobSquarePants'': One episode had Patrick's head come out of a hat box, which was itself in a television box.
* ''WesternAnimation/{{Animaniacs}}'': Dot had a special box in which she keeps a gigantic monster. The Warner brothers themselves can pop out of incredibly small places as well. The Water Tower counts too, as it seems to be the size of a shed, but has several rooms inside, including a bedroom, bathroom, and dining room, and in one episode, a decent-sized roller coaster.
* ''WesternAnimation/EdEddNEddy'': The Eds often end up in some very small places.
** Eddy once managed to stuff himself into a bucket.
** Edd managed to fit inside his sock hat.
* ''WesternAnimation/LooneyTunes'': WesternAnimation/BugsBunny is known for stuffing some of his foes into rather tight spaces. For example, in "[[WesternAnimation/BugsAndThugs Bugs and Thugs]]", Bugs stuffed two fully grown gangsters into a rather small oven...twice!
** Another gag is the folding box. put someone in it, fold it like cardboard, then fold it again... and again...
* ''WesternAnimation/TheFairlyOddParents'': "I will now hide inside my own pants. Presto!" Timmy succeeds... until Vicky yanks him out.
* [[WesternAnimation/FamilyGuy "Peter, get out of the fridge!"]]
* The closet doors from ''WesternAnimation/MonstersInc''.
* WesternAnimation/DannyPhantom uses this plenty. One wonders how [[ItMakesSenseInContext a soup can can hold an unlimited amount of ghosts.]] It's even lampshaded at one point:
--> '''Danny:''' How on earth did they cram [[RoguesGallery all of you]] into the Spectre Speeder?
--> '''Ember:''' You ever been stuck inside your stupid Thermos? Compared to that, it was the Taj Mahal in there!
* In ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'' Orko has been seen rolling himself up inside his own hat.
* ''WesternAnimation/{{Futurama}}'' has done this a couple times using Bender's chest cavity.
* On ''WesternAnimation/DarkwingDuck'', the alien superhero Comet Guy has a spacesphip that's small enough for him [[CoolHelmet to wear as a helmet]], and he can somehow fit himself and a passenger inside it.
* ''WesternAnimation/WeBareBears'': Spoofed in the episode "Chloe". The bears hide in their bearstack in a bush, but Grizzly is still visible.
-->'''Grizz''': Is there any room down there?

[[folder: Real Life]]
* One variation on a very old joke about a scientist, a mathematician, and an engineer ends with the mathematician inside a can of beans.
* Several people smuggled girlfriends/wives out of East Berlin in some impossibly tight spaces like a suitcase (or two), a photocopier and a hollowed-out car seat. Some of the more inventive contraptions are on display at the Berlin Wall Museum.
* Professional contortionists can bend their bodies in ways that seem impossible, and use that skill to fit in small, equally impossible-seeming, spaces.
* Anyone who's had a cat has probably found him or her hiding in some impossibly small place.
