On Dec 20, 2009. Julie from MS Asked “ what are the age and height requirements for most activities for the theme parks ?” Ride restrictions at Walt Disney World are based on height, not age. Most of the rides at Walt Disney World have no height requirement. However, for the safety of guests there are height requirements for some attractions. These height requirements vary widely; the requirement could be anywhere from 40 to 52 depending on the ride. You can find a complete list of height requirements on the WDW website.
