Gravel Driveway Volume and Weight Calculator
Enter your driveway's length, width and depth to calculate how much gravel volume and weight you'll need to order.
Gravel Driveway Volume and Weight Calculator
Calculates the volume and weight of gravel needed for a driveway based on its dimensions and gravel density.
This calculator multiplies driveway length, width and gravel depth to get the required volume, then multiplies by gravel density to estimate the total weight — useful because gravel is usually sold and delivered by weight (tonnes) rather than volume. Density is left as an adjustable input since it varies by stone type and size, so check with your supplier for their specific product's density before finalizing an order, and add a small extra margin for compaction and spillage.
Example
- With the default values shown above, this calculator returns: Gravel Volume Needed ≈ 1.5 m³; Gravel Weight Needed ≈ 2.4 tonnes.
Frequently Asked Questions
Why does gravel density vary?
Density depends on the type and size of stone and how tightly it's compacted, so it's left adjustable — ask your supplier for the specific density of the gravel you're ordering for the most accurate weight.
Should I order extra gravel?
Yes, a small extra margin (around 10%) is common practice to account for compaction, uneven subgrade, and spillage during spreading.
