What is the standard step height?

• A. 5 inches
• B. 9 inches
• C. 11 inches
• D. 7 inches

Answer: (D)

The standard step height is seven inches. This rise provides a balance between safety and efficiency for most people: it requires a moderate knee and ankle range of motion, keeps the foot well clear of the step below, and allows a steady, manageable cadence without overloading the joints. If the rise were much lower, like five inches, you’d accumulate more steps to climb the same height, which can be inefficient in daily tasks; if it were much higher, such as nine or eleven inches, the knee and hip effort increases significantly, making stairs harder to negotiate and raising the risk of trips or falls for many individuals. So seven inches is the typical, widely used height.
