What is the recommended workplace step height?

• A. 6-8 in
• B. 7-9 in
• C. 8-10 in
• D. 9-11 in

Answer: (B)

In workplace design, steps should have a rise that is easy to step over and consistent, helping people move safely without overworking the joints. A step height of about seven to nine inches is the standard sweet spot. It reflects common stair design and keeps knee and hip flexion at a comfortable level, reducing fatigue and the risk of trips or loss of balance during ascent or descent. Heights higher than this—like eight to ten or nine to eleven inches—require more effort and greater knee and hip bend, which can increase the chance of missteps, especially for taller or older workers or anyone with mobility limitations. A lower range, such as six to eight inches, is workable but not as aligned with typical design standards and can mean more total steps to cover the same distance, adding fatigue over a workday. So, seven to nine inches best balances safety, comfort, and practicality.
