Stair Calculator

The Monograph stair calculator is used to determine the number of steps required for a given run of stairs. Additionally the calculator can solve for stair rise and run, stair angle, stringer length, step height, and tread depth

The stringers are the strucural boards that run on either side of a staircase and are cut in a saw tooth pattern. The steps (treads) are attached to these stringers to create a rigid structure for a full stair construction.
The horizontal boards that you step on are called treads. The treads or "steps" rest on top of the stringers and complete a stair assembly.
Risers are optional but are often part of the stair structure. The risers are the vertical elements that cover the opening in the stairs and provide a bit more stability.
