Our Mission

At StairCalc Pro, we believe that layout calculations shouldn't be a source of frustration. Founded by carpenters for builders, our mission is to eliminate math errors in construction layout and empower contractors and DIYers alike with professional tools.

Our Story

StairCalc Pro was born on a jobsite when a simple math error on a set of deck stairs resulted in wasted material and hours of rebuilding. We realized that while calculators existed, none provided real-time visual feedback of the actual cuts and proper adjustments like the bottom step drop.

Today, StairCalc Pro is a trusted online resource for carpenters, home builders, and weekend DIY enthusiasts worldwide. We continuously refine our layout formulas to adhere strictly to the International Residential Building Code guidelines.

Our Core Values

Precision

In carpentry, fractions of an inch matter. We target exact measurements down to 1/16th of an inch.

Simplicity

We translate complex mathematical geometry into straightforward visual layouts and framing square guides.

Safety First

All stair calculations automatically validate against local IRC structural standards to ensure safe, stable designs.
