See how much gravel you need — in cubic yards and tons — from the length, width, and depth of the area.
Gravel weighs roughly 1.4 tons per cubic yard, varying by type and moisture. Order about 10% extra for compaction and spread. Estimate only.
Gravel is sold by the cubic yard or the ton. Multiply length × width × depth (in feet) for cubic feet, divide by 27 for cubic yards, then multiply by about 1.4 to estimate tons.
Cubic yards = L × W × (depth ÷ 12) ÷ 27 · Tons ≈ cubic yards × 1.4
About 2–3 inches for a walking path, and 4–6 inches (often in layers) for a driveway that carries vehicles.
Suppliers sell both. Weight per yard varies by stone type and moisture, so confirm the conversion with your supplier for a precise order.
