Stair Stringer

Stair Stringer is a Chrome extension that calculates the essential stringer measurements you need to build a staircase. It computes risers and run, stringer length, stair angle, step height, tread depth, and the total number of steps for a given run. You can easily adjust parameters and switch between Imperial and Metric units.

Results can be emailed or texted, making it simple to share specs with contractors or teammates. A practical tool for builders, carpenters, and DIY enthusiasts planning stair projects.
