Stair Stringer Calculator for Rise and Run
Stair stringer rise and run layout starts by choosing riser count from total rise, then recomputing actual riser height, tread count and total run.

Riser count
risers = ceil(total_rise / target_riser)
Actual riser
actual_riser = total_rise / risers
Stringer length
stringer_length = sqrt(total_rise^2 + total_run^2)
