Terms of Use

The widget is free for any website, commercial or personal. We only ask that the attribution link back to GravelCalc.com remains visible and unmodified — it is how we keep the tool free. You may adjust the iframe width and height to fit your layout. The calculator is served from our domain, so density figures and formulas stay up to date automatically with no maintenance on your side. Questions or feature requests? Get in touch.

Prefer to Link Instead?

If an embed doesn't fit your layout, you're welcome to link directly to the gravel calculator, the driveway calculator, or cite figures from our gravel coverage chart with attribution.
