Risers Only — Custom Height
You’re building an access stairway
for a client who can’t handle conven-
tional-height risers. If the total rise is 3
feet 8-3/4 inches and your desired
riser height is approximately 5-1/2
inches, find the number of stair risers,
actual riser height, and any underage
or overage remaining.
