How much gravel for a 4 x 4 m area?
A starting estimate for a 4 x 4 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
- 0.8 m3 (1.05 yd3)
- Weight
- 1.41 t (1.55 US tons)
- Bag count
- 71 x 20 kg bags
A 4 x 4 m area at 5 cm finished depth needs the volume, tonnes, and bag count shown below. For larger areas like this, compare small bags against a bulk bag or loose load for cost and handling.
Example inputs used
- Length: 4
- Width: 4
- 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.
- Compare bag delivery with bulk-bag or loose-load pricing for larger areas.
This is an estimate. Site conditions, compaction, and aggregate type can change the final quantity.
