How do you measure for stairs?

Measure out that distance from the deck to find the exact landing point. From this point, you can measure the exact stair height and determine the stringer and skirt length. Measure the exact total rise (Photo 1). Divide the height (X) by your estimated number of risers to find the exact riser height.

How do you figure out stair treads?

Use a calculator to calculate the stair riser length or the number of steps you'll need. Divide the height from the first floor to the top of the second floor by a predetermined height of your choice for the riser. The typical height of a riser is 6 or 7 inches (15 to 17.5 cm).

How do you cut stair stringers?

If it does, lay out the stringer so that the crown on the completed stair will face upward.
  1. Lay out the first tread and the second riser.
  2. Lay out the second tread and the third riser.
  3. Mark the back of the top tread.
  4. Mark the plumb cut at the top of the stringer.
  5. Lay out the bottom riser.
  6. Adjust the first riser height.
