Gravel & Slate Calculator FAQs

How much gravel do I need for my driveway?
Calculating an accurate estimate of how much gravel or aggregate you need for a driveway is simple with our gravel calculator. All you need to know is the desired length and width of the driveway, along with what gravel depth you need. You can get an estimate right now using the calculator above.

How much gravel do I need for my garden?
To calculate how much gravel you require for your garden, you must know the approximate area you are working with, and the desired depth. For gardens, this can be trickier as the shape may not be a simple square. We recommend extending this to make it a square, as it is better to order too many aggregates than too few.

What depth of gravel do I need?
You would usually lay a 10mm aggregate at a depth of 30-40mm, but on a driveway this would need to be at least 50mm. A 20mm aggregate would need to be at least 40-50mm deep, and at least 50-60mm on driveways. A larger aggregate will settle and bond together better than smaller ones. The depth you will need to select for your gravel or slate will always depend on the aggregate size and what the surface will be used for.

Example gravel estimate
We estimate an area of 5 metres by 5 metres, with a depth of 40mm, would require approximately three bulk bags of aggregates, slate chippings or gravel.

What is the density of gravel?

The density of gravel varies depending on the type of gravel you select. Smaller pebbles and gravels have a lower density while larger ones have a higher density.

Can you use the gravel calculator for all aggregates?

Our gravel calculator can be used for most gravel and aggregates featured on our website.

Do you need assistance?
