Calculate how much gravel, crushed stone, or aggregate you need for driveways, pathways, drainage, and landscaping. Get results in cubic yards, tons, and estimated cost. Supports 6 material types with accurate weight conversions.
Laying a 10×40 foot gravel driveway at 4 inches deep with crushed stone? You need approximately 4.9 cubic yards, which weighs about 6.7 tons. At typical bulk prices of $40–$60 per ton delivered, that's roughly $267–$400 in materials. Most landscape supply yards offer bulk delivery by the truckload — for jobs over 2–3 tons, bulk is almost always cheaper than buying bags.
| Depth | Area Covered per Cubic Yard |
|---|---|
| 2 inches | 162 sq ft |
| 3 inches | 108 sq ft |
| 4 inches | 81 sq ft |
| 6 inches | 54 sq ft |
| 12 inches | 27 sq ft |
| Driveway Size | Cubic Yards | Tons |
|---|---|---|
| Single car, 10×20 ft (4" deep) | 2.5 | 3.3 |
| Single car, 10×40 ft (4" deep) | 4.9 | 6.7 |
| Double wide, 16×40 ft (4" deep) | 7.9 | 10.7 |
| Large, 20×50 ft (4" deep) | 12.3 | 16.7 |
A single-car driveway (10×40 feet at 4 inches deep) needs about 4.9 cubic yards or 6.7 tons of crushed stone. A double-wide driveway (16×40 feet) needs roughly 7.9 cubic yards or 10.7 tons. Always add 10–15% extra for spreading and settling.
Between 2,400 and 2,700 pounds depending on the type. Crushed stone averages 2,700 lbs per cubic yard (1.35 tons). Pea gravel and limestone are lighter at about 2,500 lbs per cubic yard (1.25 tons).
4 inches minimum for light passenger vehicles. Use 6–8 inches for heavy traffic or soft soil. The best driveways use a 4-inch compacted base of larger crushed stone topped with 2 inches of finer gravel.
Both. Most bulk suppliers quote by the ton because that's how their trucks weigh it. Bagged gravel at hardware stores is sold by the bag (usually 0.5 cubic feet per bag). For any serious project, buy bulk by the ton.
Bulk crushed stone typically runs $40–$60 per ton delivered, depending on material type and your distance from the quarry. Pea gravel and river rock are often $50–$75 per ton. Delivery fees vary — some suppliers include delivery, others charge $50–$100 per load.
A standard single-axle dump truck carries about 10–14 tons. A tandem (double-axle) carries 15–20 tons. For a typical single-car driveway at 6.7 tons, one load usually covers it.

💡 Order 10–15% extra for compaction — a 6" base loses about 1" of depth when compacted.
