How to Use the Gravel Calculator
This calculator estimates the weight of gravel 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 gravel in inches (converted automatically to feet).
- Enter Density (lbs/ft³) – The material density (default is 100 lbs/ft³; adjust if needed).
- Click "Calculate" – The result shows the total weight in tons, along with the volume and weight breakdown.
Note: All measurements use imperial units (feet, inches, pounds). Ensure consistency for accurate results.

Frequently Asked Questions
Measure the length and width of the area in feet, and the desired depth in inches. Multiply these to get the volume in cubic feet, then multiply by the gravel density (typically 100 lbs/ft³) and divide by 2000 to get tons.
Common gravel density ranges from 90 to 120 lbs per cubic foot. For general purposes, 100 lbs/ft³ is often used.
This calculator uses feet for length/width and inches for depth. Ensure your measurements are in these units for accurate results.
