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
Thickness 10 Inches*. Find all stair values, then calculate the Run.
*Note: Headroom and Floor Thickness are required to calculate the height of the stair-
well opening.

3. Find Riser height, number of Risers, Riser Overage/Underage,
Tread width, number of Treads, Tread Overage/Underage, length of
stairwell opening, Stringer length and Angle of Incline. As a final
