Decorative Aggregate Calculator

Not sure how much gravel or pebbles you need for your garden or driveway project? Use our calculator to give you a better idea!

We have created a guide to help you estimate the amount of gravel you may need for your project.

Follow the steps below (which can also be found here):

The first step is to calculate the area of the section you would like to cover with gravel. The area calculation = A x B (Where A & B are 2 sides of a square or rectangular area).

For example, if your driveway measures 4m wide (A) by 12m long (B) the total area you need to cover is 48 sqm. 

If you are looking to fill a driveway or path with gravel, we recommend the depth of the area should be 50mm thick as it will experience higher traffic. For covering planted areas, the depth only needs to be around 30mm thick.
