About this calculator
Gravel volume is area times depth — and because gravel is sold by weight as often as by volume, the tonnage matters: typical crushed stone runs about 1.4 tons per cubic yard. A 10 × 10 ft area at 4 inches deep needs about 1.23 cubic yards, roughly 1.7 tons.
Depth depends on the job: 2–3 inches for a decorative topping over landscape fabric, 4 inches for paths, and driveways are best built in two or three compacted layers totalling 8–12 inches, with larger base stone below and finer gravel on top — calculate each layer separately.
Densities vary by material: pea gravel is a little lighter (~1.35 tons/yd³), crushed granite heavier (~1.5). Suppliers quote their own figures; the 1.4 default is a sound middle estimate for ordering.
