Use this free gravel calculator to plan a home-improvement or DIY project from the measurements and product information you already have.
HomeCalc shows the formula behind the result and keeps product-dependent assumptions editable where possible, so the calculator can match the material, package or supplier you actually plan to use.
Enter length, width and depth. HomeCalc calculates volume and multiplies cubic yards by your chosen tons-per-yard density.

Gravel Calculator: Cubic Yards, Volume & Tons
Estimate gravel volume and approximate weight for driveways, paths and landscaping projects.
Estimated result
Calculate gravel volume first, then estimate weight
Gravel quantity starts with the volume of the layer you are building. HomeCalc uses length, width and depth to calculate cubic feet and cubic yards, then applies an editable tons-per-yard value to provide an approximate weight.
cubic yards × tons per cubic yard = estimated tons
What to check before using the result
- Measure compacted or finished layer depth, not the height of a loose pile.
- Different gravel types and moisture levels can have different bulk densities.
- Driveway bases may use more than one material layer, so calculate each layer separately.
- Supplier loads are sold in practical increments; confirm minimum delivery and truck capacity.
Cubic yards measure volume while tons measure weight. The conversion depends on material density, which changes with stone type, grading and moisture. Use the supplier's density or tons-per-yard figure when available.
