How to calculate gravel for a driveway
To calculate driveway gravel, multiply the driveway length by its width and planned gravel depth. For imperial measurements, convert depth from inches to feet first. Then divide cubic feet by 27 to convert to cubic yards.
Driveway gravel formula
Length × Width × Depth = Cubic Feet
Cubic Feet ÷ 27 = Cubic Yards
Cubic Yards × Tons Per Cubic Yard = Estimated Tons
Common driveway depths
Example: 100-foot gravel driveway
For a driveway that is 100 feet long, 12 feet wide, and 6 inches deep, the volume is 600 cubic feet. Divide by 27 to get about 22.22 cubic yards before waste. At 1.4 tons per cubic yard, that is about 31.11 tons before waste.

Gravel driveway FAQ
How do I calculate gravel for a driveway?
Multiply driveway length by width by depth to get volume. Convert depth from inches to feet, divide cubic feet by 27 to get cubic yards, then multiply by tons per cubic yard.
How deep should gravel be for a driveway?
A light residential gravel driveway often uses 4 to 6 inches. Heavier-use driveways, poor soil, or truck traffic may need 6 to 12 inches or a layered base.
How many tons of gravel are in a cubic yard?
A common planning estimate is about 1.4 tons per cubic yard, but actual weight depends on gravel type, moisture, compaction, and supplier specs.
Should I add waste to a gravel driveway estimate?
Yes. A 5% to 10% waste allowance is useful for spreading, compaction, uneven ground, and material loss.
How many tons of gravel do I need for a driveway?
The tons of gravel needed for a driveway depend on driveway length, width, gravel depth, waste allowance, and gravel density. Multiply length by width by depth, convert to cubic yards, add waste, then multiply by tons per cubic yard.
How many truckloads of gravel do I need for a driveway?
Truckloads depend on total estimated tons and truck capacity. A small dump truck may carry about 5 tons, a standard dump truck about 10 tons, and a larger dump truck or tri-axle about 15 tons, but actual capacity varies by supplier and local weight limits.
How much does gravel driveway delivery cost?
Gravel driveway delivery cost depends on supplier distance, truck size, fuel charges, minimum order rules, dump location access, and local pricing. This calculator lets you enter a delivery fee so you can estimate material plus delivery total.
