Stairs — Given Only Floor-to-Floor Rise
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.
