What is the acceptable range for handrail diameter?

• A. 1/2 to 2 inches
• B. 1/4 to 1 inch
• C. 1 to 3 inches
• D. 3/4 to 1 1/2 inches

Answer: (A)

Handrail diameter should be sized so most people can grasp it comfortably and securely during use. The range from 1/2 inch to 2 inches provides a balance that works for different hand sizes and glove use, helping ensure a stable grip on stairs or ramps. If the rail is too small (less than 1/2 inch), it can be difficult to hold firmly and may slip. If it’s too large (more than about 2 inches), you may not be able to wrap your fingers fully around the rail, reducing grip stability. The other options either risk being too narrow or too wide for most users, making secure grasping harder.
