    • This includes the thickness of the finished flooring on both levels.
  2. Total Run:
    • This is the horizontal distance covered by the staircase.
    • It’s measured from the face of the first riser to the face of the last riser.
    • If there’s a landing, measure each stair run separately and add them together.

Determining Riser Height and Tread Depth

  1. Estimate the Number of Risers:
    • Divide the total rise by a comfortable riser height (usually between 7 and 7 ¾ inches).
    • Round the result up to the nearest whole number to get the number of risers.
  2. Calculate Exact Riser Height:
    • Divide the total rise by the number of risers.
    • Ensure all risers in a flight have the same height (variation should not exceed 3/8 inch) to avoid tripping hazards.
  3. Calculate Tread Depth:
    • Use the “rise + run = 17-18 inches” rule of thumb for comfortable stairs.
    • Subtract the riser height from 17 or 18 to determine the tread depth.
    • The tread depth typically includes the nosing (the overhanging lip of the tread), which is usually about 1 inch.

Laying Out the Stringer

  1. Choose Stringer Material:
    • Select a suitable material for your stringers, such as 2×12 lumber for most residential applications.
  2. Mark the Rise and Run:
