This line marks the horizontal top of your stringer. Three perfect matches are what you want to achieve. The long end of the square body should be on the run measurement.

Take this dimension and divide it by the riser height. Local store prices may vary from those displayed. You could go with the 15, and 4 stringers if you knew a piano was being moved up them. With these dimensions, cut a template with the riser height and the tread depth minus one inch as 2 legs of a right triangle.
Then, secure the treads to the steps of the stringers, which is what you'll actually be stepping on when you use the stairs. .
