Stairs — Given Rise Only
You’re building a stairway with a total rise
of 9 Feet 11 Inches. Using the default riser
Height of 7-1/2 Inches and tread Width of
10 Inches, find the stair values:

To calculate stairs given run (Length) only: If
you have a value stored in Height, it will
be used in the stair calculation. You will
need to clear the value by entering zero
into Height (e.g.
0 h).
