Stair Calculations - Using Total Rise (Or "Floor-To-Floor" Height) - Victor C6000 Instruction Manual

STAIRS CALCULATIONS - USING TOTAL RISE (OR "FLOOR TO FLOOR" HEIGHT)
Example: You need to build a staircase where the measurement of the total rise is 11 Feet 10 Inches.
Assume you are using the industry standard measurements for stair riser height (7-1/2 Inches), stair
tread width (10 Inches), floor thickness (10 Inches), and a headroom height of 6 Feet 8 Inches.
Find the following values:
riser height
number of risers
riser underage/overage
Also, calculate the run required for the staircase.
