Step 3 · Determine Actual Riser Height

Using the total rise and the rounded number of risers from the previous step, divide the total rise by the number of risers to calculate the precise height of each individual riser. For the example of a 100-inch total rise and 13 risers, the actual riser height would be 100 inches / 13 risers = approximately 7.69 inches per riser.
