How many tons of gravel for a driveway?
Quick Answer
A standard single-lane gravel driveway (12 feet wide, 4 inches deep) requires approximately 1.5 tons of gravel per 10 linear feet, or 15 tons per 100 linear feet. For a 200-foot driveway, plan on 30 tons. Gravel weighs about 1.4 tons per cubic yard.
Quick Reference Table
| Driveway length (12 ft wide, 4" deep) | Tons of gravel needed |
|---|---|
| 50 feet | ~7.5 tons |
| 100 feet | ~15 tons |
| 150 feet | ~22 tons |
| 200 feet | ~30 tons |
| 300 feet | ~45 tons |
How to Calculate It Yourself
- 1
Measure driveway length × width in feet.
- 2
Multiply by depth in feet (4" = 0.333 ft): length × 12 × 0.333 = cubic feet.
- 3
Divide by 27 to get cubic yards.
- 4
Multiply cubic yards by 1.4 to get tons (crushed stone density).
- 5
Example: 200 ft × 12 ft × 0.333 = 800 cu ft ÷ 27 = 29.6 yd³ × 1.4 = 41 tons.
Pro Tip
Order gravel in layers: 6 inches of large base stone (2–3" crusher run), then 4 inches of 3/4" crushed stone on top. This two-layer system lasts decades vs. a single layer of uniform stone.
