Critics are blasting the new Super Nintendo attraction at Universal Studios Hollywood as “blatantly fatphobic” because the augmented reality dark ride has a size restriction that will leave many Americans with larger waistlines on the sidelines.

The new Mario Kart: Bowser’s Challenge ride debuting on Friday, Feb. 17 in Super Nintendo World at Universal Studios Hollywood warns riders with a waistline measuring 40 inches or more that they may not be allowed to ride.

The average American waist circumference measures 40.5 inches for men and 38.7 inches for women, according to the U.S. Centers for Disease Control and Prevention.

Universal Studios officials told Gizmodo the 40-inch waistline guideline is not absolute and that some larger visitors may still be able to ride Bowser’s Challenge depending on individual circumstances.
