How many inches should there be between a handrail and an adjacent wall?

• A. 1/4 inch
• B. 1/2 inch
• C. 1 1/2 inches
• D. 2 inches

Answer: (C)

Having enough space between the handrail and the wall is about ensuring a secure, comfortable grip. The clearance must be enough so your fingers can wrap around the rail without being pressed into the wall, which helps you grip firmly and safely as you move along the stairs. The code sets the minimum distance at 1 1/2 inches from the wall to the handrail surface. This gap provides room for a natural grasp on typical round handrails and keeps the grip free from snagging or crowding the wall. Clearances smaller than this (like a quarter or half inch) wouldn’t allow a proper grip, while a larger gap (such as two inches) is acceptable but exceeds the minimum requirement.
