The Gravel Calculator estimates the volume and weight of gravel, crushed stone or sand needed for a driveway, path or bed.
Gravel needed: 2.78 cubic yards
| Cubic yards | 2.78 |
| Cubic feet | 75 |
| Cubic meters | 2.12 |
| Weight | 3.89 tons |
Gravel needed: 0.73 cubic yards
| Cubic yards | 0.73 |
| Cubic feet | 19.63 |
| Cubic meters | 0.56 |
| Weight | 1.02 tons |
Volume = length × width × depth; divide cubic feet by 27 for cubic yards. Gravel is often sold by the ton, so multiply cubic yards by the density: typical gravel weighs about 1.4 tons per cubic yard.
Worked example (defaults): 20 × 15 ft at 3 inches is 75 cubic feet = 2.78 cubic yards ≈ 3.9 tons.
Garden paths: 2–3 inches. Driveways: 4–6 inches of base plus 2–3 inches of top gravel. Drainage and French drains: deeper, with landscape fabric to keep soil out.
Crushed stone with angular edges locks together for driveways. Pea gravel is smooth and comfortable for paths and play areas. River rock is decorative. Sand is used for leveling and under pavers.
How much does a ton of gravel cover? About 80–100 sq ft at 2 inches.
Should I add extra? Yes, 5–10% for compaction and spillage.
Do I need edging? It helps keep gravel in place.
