Gravel Quantity Calculator

Estimate compacted volume, material tons, an order range and truckloads from driveway dimensions.

Planning use only. Results depend on your measurements, local material properties and site conditions. They are not engineering approval or a contractor quote.
Enter your measurements, then calculate.

Method and assumptions

yards = length × width × (depth ÷ 12) ÷ 27. Estimated tons are cubic yards multiplied by the editable density. Order tons add the adjustment percentage; the displayed range is ±5% around that planning quantity. Truckloads round up by your entered truck capacity. No single density is universal.

Example and limitations

Use measured dimensions and replace defaults with supplier or local information. Density, material names, truck payloads, prices and requirements vary. Round ordering quantities only after confirming how the supplier sells and delivers material.

Methods follow basic volume arithmetic and general unpaved-road principles. Review FHWA maintenance resources, local road-authority requirements and manufacturer data. See our sources methodology, drainage guide and printable project brief.
