How we calculate this
Gravel volume follows the same length × width × depth ÷ 27 formula as any bulk material. Since gravel is usually sold by weight, we convert cubic yards to tons using a material-specific density (roughly 2,400–3,000 lbs per cubic yard depending on the material).
Example
Measuring tips
For driveways and paths, 4–6 inches of base material is typical. For walkways and decorative gravel beds, 2–3 inches is usually enough.
Common mistakes
- Assuming all gravel types weigh the same — decomposed granite and crusher run have different densities.
- Not accounting for compaction, which can reduce depth after installation.
- Ordering by cubic yards when the supplier only sells by the ton, or vice versa.
Frequently asked questions
How much does a cubic yard of gravel weigh?
Roughly 2,400–3,000 lbs (1.2–1.5 tons) depending on the material — crushed stone and crusher run tend to be denser than pea gravel.
How deep should a gravel driveway base be?
Most driveways use a 4–6 inch compacted base layer, sometimes more for heavy vehicle traffic.
Can I use a different density than the preset?
Yes — enter your own density override if your supplier provides a specific figure for their material.
