You’re building a stairway with a total rise of 9 Feet 11 Inches. Your
desired riser height is 7-1/2 Inches and desired tread width is 
10 Inches. The desired headroom is 6 Feet 8 Inches and floor thick-
ness 10 Inches*. Find all stair values, then calculate the run.

*Headroom and floor thickness are required to calculate the length of the stairwell
opening.

1. Enter known Rise:

6. Find riser height, number of risers, riser underage/overage, tread
width, number of treads, tread overage/underage, length of stairwell
opening, stringer length and angle of incline. As a final step, calcu-
late the run.
