This stair reference table shows the number of steps for a range of total rise (floor to floor) values, assuming an ideal riser height of 7 in. Every figure is computed with the same engine that powers our Stair Calculator, so the numbers are exact.

How to use this table
Find the row closest to your total rise (floor to floor) and read across to the number of steps. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Stair Calculator for a precise answer.
