Estimate gravel volume and editable density-based tonnage for paths, beds, driveways, and drainage.
Use this calculator when you need gravel for a path, driveway area, or another measured section and want to see both volume and estimated weight. The density field stays editable because the same volume can weigh different amounts.
Area multiplied by depth gives volume. Cubic yards multiplied by the entered tons-per-yard density gives estimated tons.
At 600 sq ft and 4 inches, the volume is 200 cu ft, or 7.41 yd³. At the typical 1.4 tons per cubic yard estimate, that is about 10.37 tons.
Ask whether the supplier's tonnage is loose, delivered, or based on a particular moisture condition. Confirm truck access and plan any base material separately.
Rock size, moisture, density, bag fill, delivery terms, and the material blend can vary. Use the supplier's density and package information when you have it.
This tool does not design driveway base depth, compaction, drainage, or load capacity. Tonnage can change with the material and its condition.
Volume tells you how much space the gravel fills. Density is used to turn that volume into an estimated weight.
Ask the supplier for the density used for the material you plan to buy. Replace the starting value with that information when available.
It can help with early material planning, but it does not choose base depth, drainage, compaction, or load requirements.
Short, practical help for the next step in this project.
