How this calculator works
Calculate gravel volume for driveways, paths and base layers, then convert volume to an approximate weight using an adjustable density.
Cubic yards = length × width × depth in feet ÷ 27. Tons = cubic yards × material density.
Example
A 30 × 10 ft area at 4 inches deep is roughly 3.7 cubic yards before compaction or overage.
How to get a better estimate
- Stone density varies by type and moisture.
- Compaction can increase the delivered quantity needed.
- Your supplier can give the best tons-per-yard value for the exact aggregate.
What the result means
The result is a planning estimate. Dimensions, coverage, density, packaging and installation conditions vary by product and project. For purchasing, compare the result with the exact product label or supplier specification. For structural, electrical, code-regulated or safety-critical work, use an appropriately qualified professional.
