Gravel Calculator
Gravel tonnage and volume for a drive or path, from area and depth.
What is Gravel?
Gravel is sold by the ton or by the yard, and the two connect through density: weight = volume × density. A cubic yard of loose dry gravel weighs about 1.35 short tons (100 lb/ft³); compacted, more. The depth that matters is the *finished* surface — loose gravel compacts down, so 10–15% extra is ordered to land at the spec depth.
How it works
Area × (depth ÷ 12) gives cubic feet, which divide by 27 into cubic yards and multiply by the density into pounds, then by 2,000 into short tons. The density is editable with common presets, and leaving it blank gives volume only for when the supplier prices by the yard.
