A doorway width of 32 inches is commonly specified for accessibility in commercial interiors.

• A. True
• B. False
• C. Only for exterior doors
• D. Depends on local code

Answer: (A)

Providing a 32-inch clear doorway opening is a standard practice to ensure accessibility in commercial spaces. The key point is the clear width: when a door is open to about 90 degrees, there should be at least 32 inches of unobstructed width for a person using a wheelchair or other mobility devices to pass through comfortably. This measurement refers to the space available, not the door’s nominal width. In practice, doors are often specified wider (nominally 34–36 inches) so that, after accounting for the door thickness, hardware, and frame, the actual clear opening meets or exceeds 32 inches. Some local codes may require broader openings in certain situations, but 32 inches is the commonly referenced minimum for accessibility in commercial interiors.
