What it is

Gravel Calculator tells you how much gravel, aggregate or hardcore to order for a driveway, path or base: the volume, the weight in tonnes or tons, and the number of bulk bags.

Features

How it works

Volume is length × width × depth. Weight is the volume times the gravel's density, which you can set for your material, and bulk bags are the volume divided by the bag size, rounded up.

Honest limits

  • Densities vary by stone and moisture; your supplier's figure is best.

Questions

How much gravel do I need for a driveway?

Multiply length by width by depth for the volume, then by the gravel's density for the weight. Gravel Calculator does this and gives the number of bulk bags too.

How do I convert cubic metres of gravel to tonnes?

Multiply the volume by the gravel's density. Gravel Calculator uses a density you can change to match your supplier's figure.
