How it works
Cubic yards = area × depth ÷ 324; tons ≈ cubic yards × 1.4Frequently Asked Questions
How much gravel do I need for a driveway?
Multiply area by depth: a 30 × 10 ft driveway at 4 inches deep needs about 3.7 cubic yards, or roughly 5.2 tons of crushed stone. Deeper bases for heavy vehicles need proportionally more.
How deep should a gravel driveway be?
4 inches for light use over firm ground; 6–8 inches (often in layers) for a proper base on soft ground or under regular vehicle traffic. Deeper resists rutting.
How many tons in a cubic yard of gravel?
About 1.4 tons for typical crushed stone, though it varies with stone type and moisture (1.3–1.5). This calculator uses 1.4 to convert volume to the weight suppliers sell by.
