How to Calculate Gravel Needed
Formula
Cubic Yards = (Length × Width × Depth in feet) / 27
Tons = Cubic Yards × 1.4
Gravel weighs approximately 2,800 lbs (1.4 tons) per cubic yard. This can vary from 1.3 to 1.5 tons depending on the type and moisture content.
Example Calculation
A driveway 30 ft long, 10 ft wide, with 3 inches of gravel.
- 01Depth in feet: 3 / 12 = 0.25 ft
- 02Volume = 30 × 10 × 0.25 = 75 cu ft
- 03Cubic yards = 75 / 27 = 2.78 cu yd
- 04Tons = 2.78 × 1.4 = 3.89 tons
