HomeCalc gives planning estimates only. Product labels, package sizes, coverage rates, supplier conversions, local code, and site conditions can change the final quantity you need.

Frequently asked questions

Why is gravel weight only approximate?

Different stone types, sizes, and moisture levels can change weight per volume.

Should I order by volume or weight?

That depends on the supplier. Use HomeCalc as a planning estimate and confirm with the supplier.

Can I use the map for gravel areas?

Yes. Trace the area on the map, then send it to the calculator.
