The Gravel Calculator helps you estimate how many tons or cubic yards of gravel you need. Simply fill in the fields above and click Calculate to get an instant result.
This calculator is part of Calculate Wiki’s Construction Calculators collection.
What You’ll Need
- Length (ft)
- Width (ft)
- Depth (in)
- Gravel Density (lb/ft³)
Formula Used
Volume (ft³) = Length × Width × (Depth in ÷ 12)
Weight (lb) = Volume × Density
Tons = Weight ÷ 2000
Example Calculation
Using example inputs — Length = 20 ft; Width = 10 ft; Depth = 4 in; Gravel Density = 105 lb/ft³ — the Gravel Calculator returns:
| Value | Result |
|---|---|
| Volume | 66.7 ft³ (2.47 yd³) |
| Estimated weight | 7,000 lbs |
| Tons needed | 3.5 tons |
3.5 tons of gravel. Volume: 2.47 cubic yards.
