How to Use the Calculator   Please enter the length and width of the area you wish to put the gravel. This is measured in metres (m). Then enter the depth of gravel you wish to have using the slider. This is in centimetres (cm). The amount of gravel required will be displayed in the form of number of bags required. For irregular shaped areas - please break the area up into measurable sections as shown.   Please Note: All of our gravel is transported in large bulk bags and delivered by experienced hauliers in a rigid vehicle where the goods are lowered from the rear of the vehicle on a tail lift. The goods are then manoeuvred from the rear of the lorry to as close to your property as possible on a pump truck or pallet trolley. This calculator is offered as a guide only. Please call 01524 812476 if you need any further assistance or are unsure in any way.

If you are looking to undertake a project where decorative gravels will be used and are unsure how much you will need then use our gravel calculator. Simply enter the dimensions of your area and our calculator will do the rest. We recommend at least a 5-15cm depth for most gravel (unless stipulated otherwise on the individual product) to allow for good coverage. Enter the length and width in meters (Example 2.3m wide x 3.6m length) and use the depth slider to select the perfect depth for your product of choice. 

FAQs: How Much Decorative Gravel Do I Need for Driveways and Gardens?

1. How do I calculate how much gravel I need for my driveway?

To calculate how much gravel you'll need for your driveway, you can use the gravel calculator above. Simply enter the length, width, and depth of the area to get an accurate estimate in tonnes or cubic metres. For most driveways, a depth of 50mm to 100mm is recommended for adequate coverage with decorative aggregates.

2. What is the best way to work out how much garden gravel I need?

Use our gravel calculator above by inputting the size of your garden area and your preferred gravel depth. For light foot traffic or decorative purposes, a depth of 30mm to 50mm is usually enough. This helps you determine how much stone you will need without over-ordering.

3. How much gravel will I need for a standard driveway?

For a typical single car driveway (approximately 10m x 4m), you’ll need around 2 to 4 tonnes of decorative aggregates, depending on your chosen depth. Always use a gravel calculator to fine-tune your estimate based on the specific size of your driveway.

4. How much stone will I need for my garden project?

If you're planning a garden makeover using garden stones or garden gravel, you can calculate your needs by measuring the area in square metres and selecting the desired depth. A depth of 40mm is ideal for ground cover, and a gravel calculator can convert that into the exact weight or volume needed.

5. Can I use decorative aggregates for both driveways and gardens?

Yes, decorative aggregates such as Trent pea gravel, slate chippings, and crushed stone are suitable for both driveways and garden areas. Just ensure you're using the correct size and depth—larger stones are better for driveways, while finer garden gravel works well in borders and paths.

6. How deep should gravel be for a driveway or garden path?

For driveways, a minimum depth of 50mm to 100mm is recommended to withstand vehicle weight. For garden paths or flowerbeds, 30mm to 50mm of garden gravel or garden stones is usually sufficient. Using a gravel calculator will help you plan accurately.

7. Where can I find a reliable gravel calculator online?

Our gravel calculator above is the best way to estimate how much gravel you will need to ensure you have enough to complete your project without over-ordering. Simply enter your area dimensions and preferred depth to see how much gravel you will need for your driveway or garden project.
