What is the typical stair step rise height?

Explanation:
Risers of stairs are set to balance effort and safety with a reasonable number of steps. Seven inches provides a comfortable amount of vertical travel per step for most people, so you don’t have to lift too high with each step while keeping the total number of steps manageable. If the rise were smaller, say six inches, you’d have more steps to climb, which can increase time and fatigue. If the rise were larger, like eight or nine inches, each step requires more knee and hip flexion and raises the risk of missteps, especially for older adults or those with mobility limitations. That middle ground—about seven inches per step—is why this rise height is typical.
