Gravel Calculator
Estimate gravel volume and tonnage for driveways, walkways, drainage beds and other aggregate projects.
Cubic yardsApprox. tonsDensity + cost
Enter the gravel area
Use the installed depth you are planning. The tonnage estimate uses an editable tons-per-cubic-yard density.
Optional cost
Gravel density varies by stone type, gradation, moisture and compaction. Use your supplier's conversion when available.
Weight is approximate
Crushed stone, river rock and other aggregates do not all weigh the same per cubic yard.
Driveways need a section
Base stone, surface stone and compacted lifts may require separate quantities and depths.
