A ton of gravel covers roughly 100–110 square feet at 2 inches deep, about 70 square feet at 3 inches, and around 50 square feet at a 4-inch driveway depth. The exact figure depends on the stone: lighter pea gravel spreads a little further than dense crusher run.
Coverage per ton by depth
| Depth | Pea gravel | 3/4" crushed stone | Crusher run |
|---|---|---|---|
| 2" | ~115 sq ft | ~110 sq ft | ~95 sq ft |
| 3" | ~77 sq ft | ~74 sq ft | ~63 sq ft |
| 4" | ~58 sq ft | ~55 sq ft | ~48 sq ft |
| 6" | ~38 sq ft | ~37 sq ft | ~32 sq ft |
The math behind the chart
Gravel weighs 1.4–1.7 tons per cubic yard depending on type, and a cubic yard covers 162 square feet at 2 inches. So one ton of 3/4" crushed stone (1.45 tons/yd³) is 1 ÷ 1.45 = 0.69 cubic yards, and 0.69 × 162 ≈ 112 square feet at 2 inches. Halve it for 4 inches, and so on.
Worked example: a gravel parking pad
Say you are resurfacing a 20 × 15 ft parking area with 3 inches of crushed stone. Area: 300 sq ft. From the chart, one ton covers ~74 sq ft at 3 inches, so 300 ÷ 74 ≈ 4.1 tons — order 4.5 tons with a compaction allowance. Most suppliers sell in half-ton increments, and delivery beats hauling: 4.5 tons is nine pickup-truck trips.
