About gravel
Because ’gravel’ covers so many products, the weight per yard moves with stone size and how much fine material is in the pile. Rounded stone with no fines rolls under tires; crushed stone with fines locks together.
Hauling 40 yards
At about 56.0 tons, this is more than one typical truckload. A pickup is a poor fit for anything past a fraction of a yard; see how much gravel a half-ton pickup can carry.
Before you order
- Confirm whether the yard prices gravel by the ton or by the yard.
- Add about 10 percent for compaction and uneven ground.
- Clear a firm spot for the truck to dump.
The volume and tonnage calculator converts any area and depth into yards and tons.
Where gravel fits
Best suited to:
- Rural driveways and lanes where low upfront cost matters
- Drainage areas and around downspouts
- Temporary access while a site is under construction
Less suited to:
- Steep slopes, where loose stone washes downhill
- Spots plowed often, since plows push gravel into the lawn
- Areas next to doors, because stone tracks inside
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 20x25 area at 2 inches takes about 4.3 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
