* Genderflipped in ''Series/BuffyTheVampireSlayer'', where by the Season 6 episode [[Recap/BuffyTheVampireSlayerS6E17NormalAgain "Normal Again"]], Buffy notices that her younger sister Dawn has become taller than she is. When she was introduced in Season 5, Dawn was shorter. In this case, Buffy takes it as another sign of her Sunnydale "delusion" coming apart.

* ''Series/InterviewWithTheVampire2022'': Louis is the eldest of the de Pointe du Lac siblings, but his younger brother Paul is slightly taller than him. The follwing exchange is from "[[Recap/InterviewWithTheVampire2022S1E1InThroesOfIncreasingWonder In Throes of Increasing Wonder...]]".

** While Kara is chronologically older than Alex, she is physically the younger sister and looks even younger because Kryptonians age more slowly than humans. That said, she is over an inch taller than Alex, as Creator/MelissaBenoist is a StatuesqueStunner.

*** It's less noticeable given that Bran's legs are paralyzed so he doesn't stand, but Creator/IsaacHempsteadWright, who plays Bran Stark, is ''much'' taller than Creator/MaisieWilliams, who plays his older sister Arya. In fact, by Season 6, he grows up considerably (his actor is now 5'11) and is now the tallest of his siblings. In an interview for Season 6, Creator/RichardMadden (Robb's actor) says he feels bad for Kristian Nairn (Hodor's actor) for having to carry Isaac Hempstead-Wright (Bran's actor) around because he is so big now.

* ''Series/GameOfThrones'':
** HBO's Ser Loras Tyrell is several inches taller than his sister Margaery, and book readers (and probably most viewers) naturally assumed that he is the older sibling. However, WordOfGod has established that Margaery is the eldest Tyrell child on the show.
** Dickon Tarly, as played by Freddie Stroma, is dramatically taller than his older brother Samwell, played by John Bradley. Taken even further in Season 7, when 6'5 Tom Hopper was recast and who is not only taller but way bulkier than Stroma. This makes sense in-story, as the reason Sam is their father's [[TheUnfavorite Unfavorite]] is that he's much less athletic than Dickon, which is why [[AbusiveParents Randyll Tarly]] forced Sam to join the Night's Watch in the first place, so Dickon would be his heir.

** Lyanna's notably taller than her older brother Ned back when they were kids. Many actually thought she was the older sibling in this version because of that, but she calls Ned "big brother" in the next flashback.
** Euron is both taller and bulkier than Balon.

* Casey in ''Series/{{Atypical}}'', is younger than Sam but takes on a protective role. Because his autism can make things difficult, she is often helping him navigate dating, schooling and socialising.

* ''Series/LastManStanding'' at first had all three daughters at about the same height, with [[DawsonCasting Kristin and Mandy both played by adult actors]]. Kristin [[TheOtherDarrin was recast]] in the second season with a slightly taller actress, while Eve eventually grew taller than Mandy and was pointed out when Mandy tried making a short joke. Mandy [[TheOtherDarrin was then recast]] in the seventh season with a very tall actress, towering over both sisters and playfully ignoring the fact she was supposed to be shorter than the other two.

* Genderflipped in ''Series/BuffyTheVampireSlayer'', where by the Season 6 episode [[Recap/BuffyTheVampireSlayerS6E17NormalAgain "Normal Again"]], Buffy notices that her younger sister Dawn has become taller than she is. When she was introduced in Season 5, Dawn was shorter.

* ''Series/{{Supernatural}}'': Sam Winchester is very tall (6'4"), while his [[KnightTemplarBigBrother notoriously protective]] [[BigBrotherInstinct big brother]] Dean is several inches shorter (around 6'0"). Sam teases him about it on occasion, even though 6'0'' is reasonably tall by normal standards.

* ''Series/YoungSheldon'': Discussed in the episode "The Wild And Woolly World Of Nonlinear Dynamics", when Sheldon points out that Missy (they're twins, but Sheldon was born first) is now taller than he is. Subverted in their adult years, as Sheldon is taller than Missy in ''Series/TheBigBangTheory'' and their older brother Georgie is the tallest in both shows.

** While Kara is chronologically older than Alex, she is physically the younger sister and looks even younger because Kryptonians age more slowly than humans. That said, she is still over an inch taller than Alex, as Creator/MelissaBenoist is a StatuesqueStunner.
** Kara is 13 years older than her baby cousin Kal-El and was sent to protect him, but because she was suspended in the Phantom Zone, where TimeStandsStill, she hadn't aged when she came out of it 24 years later. By the time Kara crash landed on Earth, Kal-El had become [[Franchise/{{Superman}} an experienced, adult superhero]] who didn't need her help anymore.
