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 length of the stair-
well opening.
