The stair calculator calculates stair rise and run, stair angle, stringer length, step height, tread depth, and the number of steps required for a given run of stairs.

Use our rise over run calculator to find the slope of a line or to find the rise and run given two points on the line.

This stair calculator computes stair parameters such as rise, total run, angle, and stringer length based on the height, run, tread, and headroom requirements.

The Slope Calculator helps you calculate slope (grade or pitch) from rise and run measurements. Get results in multiple formats: percentage, angle in degrees, and ratio.
