How Much Gravel Do I Need for a Driveway?
Multiply driveway length by width by depth in feet to get cubic feet, divide by 27 for cubic yards, then convert to tons using your supplier's density estimate.
Driveway gravel estimate steps
- Measure driveway length and width in feet.
- Choose the planned gravel depth in inches.
- Convert depth to feet by dividing by 12.
- Multiply length by width by depth to get cubic feet.
- Divide by 27 for cubic yards and convert to tons if needed.
Why supplier density matters
Different gravel types weigh different amounts. Moisture, stone size, and compaction affect tonnage, so use supplier data when ordering by weight.

Frequently asked questions
Is driveway gravel ordered by yard or ton?
It depends on the supplier. Many suppliers quote by ton, but cubic yards are useful for measuring volume.
Does compaction change the estimate?
Yes. Compacted base layers may need more material than a loose volume estimate suggests.
