Estimate gravel volume and tonnage
Use project dimensions, depth, density, and waste allowance to estimate gravel quantity in cubic meters, cubic yards, and tonnes.
Results
Total volume
2.07 m3
Cubic yards
2.71 yd3
Tonnes needed
3.32
Kilograms
3,318 kg
How to use it
- 01Enter the project length, width, and gravel depth.
- 02Use the density value that best matches the type of gravel or aggregate you plan to order.
- 03Add a waste percentage to account for compaction, uneven base, and site variability.
Result guide
- Volume is shown in cubic meters and cubic yards so supplier conversations are easier across regions.
- Tonnes needed convert the volume estimate into a more common delivery-ordering unit.
- Waste is applied before weight conversion so the tonnage reflects the planned order amount rather than the ideal geometric minimum.
About this calculator
Gravel estimates are useful for driveways, drainage, landscaping, and base layers because suppliers and contractors often discuss the same material in both volume and tonnage terms.
A useful gravel page should convert the geometric volume into weight using density, because ordering is frequently done by tonnes rather than only by cubic measure.
Frequently asked questions
Why does gravel density matter?
Because different aggregate types pack differently, so the same volume can correspond to different delivery weights.
Why show both cubic yards and cubic meters?
Because different suppliers and regions quote aggregate using different volume units, and comparing both reduces conversion mistakes.
Does this include compaction perfectly?
No. The waste allowance helps cover real-world variability, but actual compaction behavior still depends on the material and site conditions.
