About YardMath

YardMath makes free calculators for the material questions that come up in yard and home projects: how many bags, how many yards, how deep. Every tool shows its formula and a worked example, so you can check the numbers yourself.

Results are estimates. Product yields vary by brand, and local building codes set requirements such as footing depth. Check the product label and your local building department before you start a project.
