What you get
This stair stringer layout tool turns a finished rise and an available run (or a tread count) into a cut list and a dimensioned stringer you can mark with a framing square. Numbers copy to your notes. Marking steps stay readable on a phone. The 1:1 tiled PDF is the paid print template.
Need the square sequence in more detail? Read how to mark a board. Compare your rise and run to common IRC figures (hints only). Start from a worked calculator stair stringer layout diagram if you want a known height first.
