What is the standard tread depth for stairs?

Can Stair Tread Depth Impact Safety? Brief Summary Yes, stair tread depth directly impacts safety. A tread that’s too shallow increases the risk of missteps and falls, particularly when descending. Conversely, an excessively deep tread can disrupt natural gait and lead to fatigue. Building codes set minimum tread depths to mitigate these risks, with OSHA […]
