What is the minimum cross-section size required for non-circular handrails?

The minimum cross-section size for non-circular handrails is established to ensure proper grip and usability for individuals who need to use them for support. A handrail with a cross-section of 1 inch provides sufficient size to allow for a comfortable grasp, while also being easy to manipulate under various conditions.

Handrails must be designed not only for safety but also for accessibility. A diameter of 1 inch presents a balance between being robust enough to withstand force while remaining compact enough for individuals with smaller hands. Larger sizes, such as 1-1/2 inches, 1-3/4 inches, or 2-1/4 inches, could hinder use for individuals who may struggle to wrap their hands around thicker materials comfortably.

The standard emphasizes that non-circular handrails with a 1-inch cross-section will also accommodate the functional requirements set by building codes and accessibility standards, providing both support and safety for users.
