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 and feet. Next, enter the length and width followed by the depth. 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 this equates to.

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

"Just a note to say that my order arrived this afternoon - all safe and sound. Delivery driver was very pleasant and helpful. I now have a lovely garden path and the Black basalt looks wonderful especially as it turns from black to grey as it dries out. Thank you so much for your excellent customer service, would definitely recommend you to anyone looking for gravel or decorative garden chippings. Kind regards Alicia"
