A 100-foot driveway at 10 feet wide takes roughly 22 cubic yards of stone — about 12.5 yards of compacted base plus 9.5 yards of top coat. The area is 1,000 sq ft; from there it is the standard formula, run layer by layer.
The math
| Layer | Depth | Yards |
|---|---|---|
| Dense-graded base | 4" | 1,000 × 4 ÷ 324 = 12.3 → 12.5 |
| ¾" top stone | 3" | 1,000 × 3 ÷ 324 = 9.3 → 9.5 |
At 6 yards of stone per truck, that is four sequenced loads, each with its own delivery fee — and volume pricing applies on multi-truck orders. Dispatch can stage the loads so the base is spread and compacted before the top stone lands. Size your own drive with the material calculator, then shop driveway gravel.
