With a variation of 3/8-inch or less. Open risers are allowed if they are 4 inches high or less.

To calculate the stair riser height, measure the height from one floor to the next. Divide that total by 7.75 inches. This is to see how many steps you will need.

According to the International Building Code that is used by most contractors, the vertical rise of a residential stair step should measure a maximum of seven more 3/4 inches.

A step’s minimum width of stair riser height is thirty six inches, and the minimum tread length is ten inches. The minimum headroom above the stairs is six feet eight inches to accommodate the height of walkers as they climb the stairs. Handrails must be placed between thirty four and thirty eight inches above a step’s nose, which is the place where the tread and the riser meet.
