Gravel volume and approximate weight
This table uses geometry plus an example density of 1.4 tons per cubic yard. Aggregate density and moisture vary, so supplier conversion factors should override the example.

Gravel should be estimated in volume first. Weight is then volume × material density. Because crushed stone types and moisture levels vary, tonnage is less universal than cubic-yard volume.
Reference table
| Area | Depth | Cubic yards | Approx. tons at 1.4 t/yd³ |
|---|---|---|---|
| 100 sq ft | 2 in | 0.62 yd³ | 0.86 tons |
| 100 sq ft | 3 in | 0.93 yd³ | 1.30 tons |
| 100 sq ft | 4 in | 1.23 yd³ | 1.73 tons |
| 250 sq ft | 2 in | 1.54 yd³ | 2.16 tons |
| 250 sq ft | 3 in | 2.31 yd³ | 3.24 tons |
| 250 sq ft | 4 in | 3.09 yd³ | 4.32 tons |
| 500 sq ft | 2 in | 3.09 yd³ | 4.32 tons |
| 500 sq ft | 3 in | 4.63 yd³ | 6.48 tons |
| 500 sq ft | 4 in | 6.17 yd³ | 8.64 tons |
| 1,000 sq ft | 2 in | 6.17 yd³ | 8.64 tons |
| 1,000 sq ft | 3 in | 9.26 yd³ | 12.96 tons |
| 1,000 sq ft | 4 in | 12.35 yd³ | 17.28 tons |
Assumptions used
- Example density: 1.4 tons per cubic yard
- Uniform depth
- Supplier density should replace the example for purchasing
Why your result may differ
Tonnage depends on the exact aggregate density, moisture and compaction. Use the cubic-yard column for geometry, then obtain density and delivery rounding from the supplier.
Methodology
Each row converts area and depth to cubic yards, then multiplies by the disclosed example density of 1.4 tons per cubic yard.
