What is the commonly recommended height for a handrail attached to a wall on a stairway?

The commonly recommended height for a handrail attached to a wall on a stairway is 36 inches. This measurement aligns with safety codes and standards, such as those outlined by the International Building Code (IBC) and other guidelines for residential construction. The height is designed to provide an optimal grip for individuals using the stairs, ensuring that the handrail is accessible for people of varying heights. At 36 inches, the handrail effectively assists users in maintaining balance and support while navigating up and down the stairs, contributing to overall safety.

Other height options, while they may be permissible in certain scenarios or jurisdictions, do not conform to the widely accepted standard that promotes safety and accessibility in stairway design. Thus, the choice of 36 inches reflects the consensus among building professionals regarding the best practices for handrail installation.
