there are no “weight restrictions” on any of Universal's theme-park attractions; instead, it comes down to how your unique body dimensions fit inside each ride's restraint system. Two people may weigh the same, but one will fit and the other will not.

Harry Potter and the Forbidden Journey, located inside Hogwarts Castle at Universal Studios, is notorious for having a restrictive restraint system that may not be comfortable or accessible for all body types. The ride uses an over-the-shoulder harness that must "click" a certain number of times to be considered safe. Generally, guests with a waistline of 40 inches or more, or those with very broad shoulders or large chests, may find it difficult to secure the harness. In 2026, Universal continues to provide test seats at the entrance of the attraction, allowing guests to check the fit privately before entering the queue. Unlike some newer rides like Hagrid’s Magical Creatures Motorbike Adventure, which has a more accommodating sidecar option, Forbidden Journey is a "one-size" seating configuration. If the test seat indicates a "red light," the ride operators cannot allow you to board for safety reasons. It is highly recommended to try the test seat first to avoid a long wait in the beautifully themed queue only to be turned away at the final boarding platform.
