ABOUT THIS TOOL

When to use a gravel calculator

Estimate material needs for paths, gardens and driveways.

All assumptions are visible and adjustable. Check rates and underlying data against original sources before making a decision.

HOW IT WORKS

The calculation

Cubic yards = length (ft) × width (ft) × depth (in) ÷ 12 ÷ 27. Estimated US tons = cubic yards × bulk density.

ASSUMPTIONS

Know the limitations

Density depends on gravel type and moisture. This calculator estimates uncompacted volume; account for compaction and waste separately.

Results are estimates derived from your inputs.
