About Sawhorse Labs

Sawhorse Labs is a set of free calculators for the "how much do I buy" part of home and yard projects.

How it's made

This site is built and maintained with the help of AI, with a person overseeing it. Every formula lives in one shared, automatically tested module. Material yields and coverage rates come from manufacturer data sheets and university extension guides, linked on each page, and the tests check the results against the examples those sources publish.

Products differ, and real jobs have uneven ground and spills. Treat the results as a careful estimate, check the label on what you buy, and follow local building codes for anything structural.
