How to use this tool?
This calculator estimates the weight of aggregate (gravel, sand, etc.) needed for a rectangular area. All inputs must be positive numbers.
- Enter Length (ft) – The length of the area in feet.
- Enter Width (ft) – The width of the area in feet.
- Enter Depth (in) – The depth of the aggregate layer in inches.
- Enter Density (lbs/cu.ft) – The material's density (default 100 lbs/cu.ft). Adjust if you know the specific density of your aggregate.
- Click Calculate.
The result shows the total weight in tons. A formula breakdown is provided below the result for verification.
All inputs use imperial units (feet, inches, pounds per cubic foot). Depth must be in inches; it is automatically converted to feet.

Frequently Asked Questions
Enter the length and width of the area in feet, the depth in inches, and the density of the material in pounds per cubic foot. Click Calculate to see the total weight in tons.
Common densities: gravel (100-120 lbs/cu.ft), sand (100-130 lbs/cu.ft), crushed stone (100-120 lbs/cu.ft). Check your material's specific density.
Volume (cu.ft) = Length × Width × (Depth/12). Weight (lbs) = Volume × Density. Tons = Weight / 2000.
