Gravel Calculator

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

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

When you've worked out the quantity required, feel free to browse our huge range of decorative gravel.
