In commercial interiors, the minimum doorway opening width required to meet common accessibility guidelines is:

• A. 28 inches
• B. 30 inches
• C. 32 inches
• D. 34 inches

Answer: (C)

Doorway width for accessibility is about providing enough clear space for a wheelchair to pass through. The key idea is the clear width of the doorway when the door is open to 90 degrees, measured between the finished surfaces of the surrounding walls, not including hardware or trim. The minimum width specified by common accessibility guidelines is 32 inches. This ensures a standard wheelchair can negotiate the opening without obstruction. Narrower openings, such as 28 or 30 inches, do not meet the requirement. A width of 34 inches is allowed and exceeds the minimum, but the essential threshold to meet the guidelines is the 32-inch clear opening.
