What is Gravel Calculator?

A gravel calculator estimates the amount of gravel needed for a driveway, path, or garden bed based on area and depth.

It converts the volume into weight (tons) so you can order the right quantity.

How does the Gravel Calculator work?

Volume = Length × Width × Depth | Weight = Volume × Density

The calculator multiplies the area by the depth to get the volume.

It then converts to tons using gravel's typical density (about 1.4-1.7 tonnes per cubic metre).

How to use the Gravel Calculator?

  1. Enter the length, width, and desired depth.
  2. Select the gravel type.
  3. The calculator shows the volume and weight needed.
