Weight assumes ~1.5 tonnes per m³. Density varies by stone type — ask your supplier if unsure.
In-depth explanation
Estimate gravel volume and weight from area and depth. Weight uses a typical bulk density of about 1.5 tonnes per m³. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
Decorative paths are often ~40–50 mm; drive bases need more — check your project. Stone density and moisture vary. Suppliers can refine the tonnage for your product.
Calculate sub-base depth separately if your build needs one. Tweak the inputs above to compare options, then copy or note the result you need.
