Gravel Calculator
Enter the area's length, width, and depth, and pick the type of gravel. We compute the cubic yardage and tonnage so you know exactly how much to order.
Gravel type
Crushed stone · 1.5 t/yd³
6.67 tons
4.44 yd³ at 4 in deep
Add 5–10% to your order to cover settling and edge spillage.
Examples
Driveway 30 ft × 12 ft × 4 in
≈ 4.44 yd³ · 6.0 tons
Walkway 25 ft × 4 ft × 3 in
≈ 0.93 yd³ · 1.3 tons
Bed 8 ft × 8 ft × 2 in
≈ 0.40 yd³ · 0.5 tons
How it works
Volume is length × width × depth, with depth converted from inches to feet. We divide by 27 to get cubic yards, then multiply by the density of your gravel type to get tons.
Volume · L × W × (D ÷ 12) ÷ 27 = yd³
Density: pea gravel ≈ 1.35 t/yd³ · crushed stone ≈ 1.5 t/yd³ · river rock ≈ 1.4 t/yd³
Frequently asked questions
Most landscape and construction gravels weigh between 2,400 and 3,000 lb per cubic yard (1.2–1.5 tons). Pea gravel is on the lighter end; crushed stone tends toward the heavier end.
Driveways are typically 4–6 inches deep, walkways 2–3 inches, and decorative beds 2 inches. Always measure deeper if you're filling over a soft or muddy subgrade.
Suppliers sell in both — tons is the standard for trucked deliveries, cubic yards for bagged or scooped quantities. Our calculator gives you both so you can match the supplier's units.
It's a careful estimate. Real-world delivery loses a small percentage to compaction, settling, and overflow at edges. Add 5–10% to be safe on important jobs.
