How much gravel a driveway takes
A gravel driveway is a long rectangle, so the volume is length x width x depth. A driveway 50 ft long and 12 ft wide with 4 inches of gravel is 200 cubic feet, or 7.41 cubic yards. With 10% extra that is 8.15 cubic yards, which is about 11.41 tons at 1.4 tons per cubic yard.
| Driveway | Depth | Cubic yards | Tons |
|---|---|---|---|
| 30 x 10 ft | 4 in | 4.07 | 5.70 |
| 50 x 12 ft | 4 in | 8.15 | 11.41 |
| 50 x 12 ft | 6 in | 12.22 | 17.11 |
| 100 x 12 ft | 4 in | 16.30 | 22.81 |
| 100 x 12 ft | 6 in | 24.44 | 34.22 |
| 200 x 12 ft | 4 in | 32.59 | 45.63 |
Things that change the amount
- Depth. Driveways are often built in layers, with larger stone below and finer stone on top. Enter each layer's depth separately and add the results.
- Width. Measure at the narrowest and widest points. Curves and turnarounds add area.
- Settling. New gravel compacts under traffic. Extra material at the start saves a second delivery.
- Delivery. Ask the supplier how large a truck they send and whether the price is per ton or per yard.
