Laying out a Stairway

The total vertical distance between finish floors in a residence is

15¹-8¹. Calculate the total number of risers in the stairway, the

height of each riser, the width of each tread and the total run of

the stairway (the horizontal distance).

2R + T = 25"

Show all calculations. Draw at a scale of 1/4" = 1'-0" a

longitudinal section through the total run of the stairway.
