How to Calculate Gravel Quantity
Gravel is sold by weight, but you plan a project by volume — so the math has to bridge both. Measure the length, width, and depth of the area in feet to get cubic feet, divide by 27 to convert to cubic yards, then multiply by the material's density (tons per cubic yard) to land on the tonnage a supplier will actually quote you.
Key Formulas
Volume (ft³) = Length × Width × Depth(ft) [depth ÷ 12 for inches] Volume (yd³) = Volume (ft³) ÷ 27 Weight (tons) = Volume (yd³) × Density (tons/yd³) Weight (lbs) = Weight (tons) × 2,000 Common densities (tons per cubic yard): Pea gravel: 1.3-1.4 t/yd³ · Crushed stone: 1.4-1.5 t/yd³ · Crushed limestone: 1.5-1.6 t/yd³ Bank gravel: 1.3-1.4 t/yd³ · Sand: 1.4-1.7 t/yd³ · Concrete gravel: 1.5-1.6 t/yd³ 1 yd³ ≈ 1.5 tons (general estimate for most gravel)
