Disney World’s 40-Inch Cutoff Now Unlocks Headliners Across All Four Parks

Overview

• Big Thunder Mountain Railroad has reopened with a 40-inch height rule, cementing a shared access tier across the resort.
• The tier includes Rise of the Resistance, Tower of Terror, Star Tours, Mission: SPACE, Test Track, Soarin’, Tiana’s Bayou Adventure, and Big Thunder Mountain Railroad.
• Magic Kingdom now offers two thrill-style options at that height, with Big Thunder lining up with Tiana’s Bayou Adventure.
• Hitting the cutoff changes trip planning by boosting the value of Lightning Lane, Disney’s paid skip-the-line option, across multiple parks.
• The 38-inch group, led by Slinky Dog Dash and Seven Dwarfs Mine Train, often helps kids build confidence before moving up.
