Gravel by project
How much gravel for a 5 x 3 m driveway?
A starting estimate for a 5 x 3 m area at 5 cm finished depth.
Estimated result
Pre-calculated from the example inputs below. Adjust them in the calculator for your own numbers.
- Volume
- 0.75 m3 (0.98 yd3)
- Weight
- 1.32 t (1.46 US tons)
- Bag count
- 66 x 20 kg bags
A 5 x 3 m driveway at 5 cm finished depth needs the volume, tonnes, and bag count shown below, using a typical decorative gravel density and a 10% waste allowance. Driveways often need a proper sub-base and a deeper top layer, so confirm the build-up for load-bearing areas.
Example inputs used
- Length: 5
- Width: 3
- Depth: 5
- Aggregate density: 1.6
- Bag size: 20
These are starting values for this example. Measure or confirm your own figures, then open them in the gravel calculator.
Assumptions and limits
- Uses a typical decorative gravel density of 1.6 t/m3.
- Includes a 10% waste and settling allowance.
- Driveways may need a sub-base and a deeper gravel layer than 5 cm.
This is an estimate. Site conditions, compaction, and aggregate type can change the final quantity.
