In 2026, Disney Parks (both Walt Disney World and Disneyland Resort) use minimum height requirements for safety rather than a "maximum" height limit for most attractions. For example, high-intensity rides like TRON Lightcycle / Run and Rock 'n' Roller Coaster require guests to be at least 48 inches (122 cm) tall. The most common cutoff for "thrill" rides is 40 inches (102 cm), which includes attractions like Big Thunder Mountain and Rise of the Resistance. However, there are rare maximum height limits on certain children's play areas and slides; for instance, at Disney's Typhoon Lagoon, some kiddie slides like the "Bay Slides" have a maximum height limit of 60 inches (152 cm). Additionally, very tall guests (over 6'6") may find certain rides like Space Mountain or the Seven Dwarfs Mine Train physically uncomfortable due to tight legroom. Disney uses a "Rider Swap" program for families with children who do not meet the height minimums, ensuring everyone gets to enjoy the attractions they are tall enough to ride.
