While most attractions and rides are available to Guests of all heights, some experiences at Walt Disney World theme parks and water parks do have minimum height requirements—and a few have maximum height requirements. View a list of attractions that are available to Guests of any height.

Disney theme park attractions are primarily governed by height requirements rather than age for safety reasons. While some play areas or specific experiences might have age guidelines, the mechanical constraints of ride restraints (such as lap bars or over-the-shoulder harnesses) require a minimum height to ensure every guest is securely held. At Walt Disney World and Disneyland, height limits range from 32 inches (81 cm) for milder rides like Autopia or Alien Swirling Saucers to 48 inches (122 cm) for high-intensity coasters like Rock 'n' Roller Coaster or Incredicoaster. Many attractions, such as Pirates of the Caribbean and it's a small world, have no height requirement and are open to all ages. For families with children who do not meet the height requirement, Disney offers a "Rider Switch" (Rider Swap) program, allowing one adult to wait with the child while the rest of the group rides, then "switch" so the waiting adult can ride without standing in the full line again.
