Pea gravel calculator
Estimate pea gravel for patios, paths and play areas. Returns yards, tons, bags and cost.
Short answer: cu yd = (L × W × depth/12) ÷ 27. Tons = cu yd × 1.35. Bag ≈ 0.5 cu ft. 12 × 10 ft × 2" = 20 cu ft ≈ 0.74 cu yd ≈ 1 ton = 40 bags. Enter your measurements above and the pea gravel calculator returns the quantity, unit conversions and an estimated cost instantly, in imperial or metric — no sign-up needed.
