What is the minimum outside door swing clearance required for wheelchairs?

• A. 18 inches
• B. 30 inches
• C. 26 inches
• D. 22 inches

Answer: (C)

When evaluating door design for wheelchair access, the key idea is that enough space is needed outside the door so the chair can approach, align, and pass through as the door swings open. A typical wheelchair is about 24 inches wide, and you need a bit of extra room to maneuver the user and avoid contact with the door or frame as it opens, so the minimum outside swing clearance is about 26 inches. This provides a safe margin for clearance without forcing the door to be wider than necessary. If the outside clearance were only 18 inches or 22 inches, the chair wouldn’t have enough room to fit and turn smoothly; 30 inches would meet and exceed the minimum, but it isn’t the smallest acceptable value.
