Estimate how many tons of crushed stone your project needs. Each dimension has its own unit (in/ft/yd/m), and the material dropdown sets the density automatically.
| Area | Shape | Length | Width | Dia | Depth | Cu Yd |
|---|
Find each area's volume, divide by 27 for cubic yards, and multiply by the density (about 1.4 tons per cubic yard for crushed stone). Driveways and bases are commonly 4-6 inches deep. Use the unit toggles for inches, feet, yards or meters and the material dropdown to match your product.
Use the crushed stone calculator for base layers, drainage stone, road base and general aggregate work. It converts measured volume to cubic yards and tons using the density you choose.
Start with the calculator that matches how your material is sold: area, length, volume, count, weight or electrical load. Enter one work area at a time, use the unit selector beside each measurement, then review the order quantity and cost fields before comparing supplier quotes.
Most calculators can save the current estimate in your browser, reload named estimates, print a copy, switch to dark mode or create a shareable link. Those tools are intended for planning and communication; always confirm final quantities, coverage rates, density, code requirements and pricing with the supplier or contractor responsible for the work.
