What is the formula for building stairs?

The vertical distance between the floors to be linked by the staircase is the principal determinant of the riser and tread dimensions. You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14).

What is a comfortable stair rise?

With a riser height of 7 1/2 inches, tread width (run) should be at least 9 inches. Ten inches is a more comfortable run; when you multiply 7 1/2 inches by 10 inches, you get 75 — within the conventional ratio of 72 to 75 inches.
