Gravel Calculator is a free collection of simple tools designed to help homeowners, DIYers, and contractors estimate gravel quantities for common projects.
How it works
- No account is required to use any calculator.
- Core calculations run locally in your browser — no network calls are needed once the page has loaded.
- Saved projects are stored on your own device in browser storage, not on a server.
- Calculations use transparent density assumptions, documented in how our gravel calculations work.
- Actual supplier quantities, densities, and increments may vary from these estimates.
What this site is not
These tools provide estimates for planning and ordering. They are not engineering or construction-design advice, and they do not replace guidance from your supplier, contractor, or local requirements.
