Gravel Calculator
Estimate gravel volume and approximate weight for a rectangular area.
How to Use the Gravel Calculator
Enter the project length, width and gravel depth to estimate material volume and approximate weight.
Practical Example
A 6 m by 3 m area with a 5 cm gravel depth needs about 0.90 m³ before allowing for compaction or settlement.
Factors That Affect the Result
Gravel density, stone size, moisture, compaction, uneven ground and delivery units can change the amount you should order.
Frequently Asked Questions
Does gravel type matter?
Yes. Different aggregates have different densities.
Should I add extra material?
A small allowance can help cover compaction and uneven surfaces.
Can I use this for driveways?
Yes, if you enter the driveway dimensions and planned depth.

Gravel Quantity Planning
Enter the project area and desired gravel depth to estimate the required volume and approximate weight. Gravel density varies by stone size, moisture and compaction, so supplier weights may differ from a theoretical estimate. Driveways and bases often need compaction and may require more material in low spots. Add a modest allowance and round up to the delivery or bag size offered by your supplier before ordering.
