Calculate the amount of gravel needed for a driveway in tons and cubic yards.

Formula

Volume (cu yd) = L × W × D(ft) ÷ 27; Tons = cu yd × 1.4
  • Use 3/4 in crushed stone or #57 stone for best driveway performance.
  • New driveways: base layer 4 in + top layer 2 in recommended.
  • 1 ton of gravel ≈ 0.7 cubic yards.

50×12 ft driveway, 6 in deep

Inputs
  • Driveway Length: 50 ft
  • Driveway Width: 12 ft
  • Gravel Depth: 6 in

50×12×0.5 = 300 cu ft = 11.1 cu yd × 1.4 = 15.6 tons.
