* The poster for ''Film/GoodBoys'' has the characters beneath a "You must be this tall to see this movie" sign, with an [[UsefulNotes/RestrictedRating R rating]] above it.

** The ''WesternAnimation/WhatsNewScoobyDoo'' episode "Roller Ghoster Ride" features a RunningGag that involves a young boy being told that he is too short to go on certain rides (such as the Sky-Diving Simulator, the Slingshot, and the Rocket Coaster). In the end, after the villain of the episode is caught, he asks the gang why he wasn't considered a suspect (despite having a decent motive to do it); Velma explains that it was because he was too small to actually fit in the costume. In the end, the boy gets to ride with Shaggy and Scooby on the food-based ride that was built for the amusement park.

In contrast, it may also be used as an excuse for a child or young teenager who is legitimately scared of said ride. Of course, the plot requires that said child actually be tall enough to ride, in which case [[BraveTheRidePlot elaborate, wacky hijinks are played in order to avoid the ride, before finally admitting his/her fear, going on anyway, and generally enjoying him/herself]]. This variant is almost always played for laughs.

However, due to pesky safety regulations, equipment and seats made to accommodate adults, not to mention pesky liability issues and lawsuit-happy parents, park regulations dictate that younger children can't ride the most intense, exciting and popular rides. In RealLife, these safety concerns are perfectly valid and are there to protect children - safety harnesses that fit an adult may be too large to properly restrain a child. In fiction, this is rarely if ever pointed out. Though rarely mentioned, the inverse of this is also true of RealLife: child-scale rides are often too small to be safe (or at least comfortable) for adults (and some adult-scale rides are too small for adults of exceptional size).

** In "The Wreck of the Mauna Loa", when Mr. Krabs believes [=SpongeBob=] and Patrick have stumbled upon what he thinks is the titular sunken ship, but is actually an amusement park ride based on it. One boy can't go on the ride due to not being tall enough, but Mr. Krabs pushes the sign down until it's shorter than the boy.
** At the end of "Say 'Awww!'", after Plankton's latest invention, Q.T.-Pi, is converted into a ride at Glove World, Plankton is dismayed when he is turned away for being too short to ride despite being the one who built the robot in the first place.
