Gravel Calculator

This gravel calculator provides a rough guide to how much product you will require to cover a specific area (such as a driveway). The depth will depend on the size of the material and its intended use.

To calculate an area, first choose your units on the left hand side, the default is kilograms and metres but this can be changed to Tons and feet. Next, enter the length and width followed by the depth. The instant results on the left hand side will show you the total area, volume and weight required including how many 20kg bags this equates to.

When you've worked out the quantity required, feel free to see our huge range of Gravel & Chippings.
