Gravel Calculator
Calculate gravel volume and estimated weight for driveways, landscaping, foundations, drainage, and construction projects.
Gravel Calculation Formula
Gravel volume is calculated by multiplying the project length, width, and depth using the same unit of measurement.
Volume = Length × Width × Depth
After calculating the volume, the approximate gravel weight is estimated using an average gravel density to help with ordering materials.
How To Use This Gravel Calculator
1. Select your preferred measurement unit.
2. Enter the project length.
3. Enter the project width.
4. Enter the gravel depth.
5. Click Calculate Gravel to estimate the required volume and weight.
Example Calculation
Suppose your project area is 20 ft long, 10 ft wide, and 4 ft deep.
Volume = 20 × 10 × 4
Gravel Volume = 800 ft³
Estimated Weight ≈ 40 tons
Why Use This Gravel Calculator?
This calculator helps homeowners, contractors, landscapers, and builders estimate gravel quantity quickly before purchasing materials.
Accurate estimates reduce material waste, save money, and improve planning for driveways, walkways, drainage systems, foundations, and landscaping projects.
