4 Cubic Yards of #57 Stone in Tons
4 cubic yards of #57 stone in tons works out to about 5.4 tons using a planning weight of 1.35 tons per yard. Real loads land between roughly 5.2 and 5.8 tons depending on stone size, fines and moisture. That is about 10,800 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 4 × 1.35 = 5.4 tons.
- Low end: 4 × 1.3 = 5.2 tons.
- High end: 4 × 1.45 = 5.8 tons.
Quarries can tell you the weight per yard for their own product; use it if you have it.

About #57 stone
Since #57 is washed and open-graded, it moves a little underfoot. Many installers put it over a compacted base of a dense-graded stone rather than straight on soil.
Hauling 4 yards
At about 5.4 tons, this is a load most single-axle dump trucks can take. 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 #57 stone 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 #57 stone fits
Good uses:
- French drains and drainage layers
- The top course of a gravel driveway
- Under sheds where water needs to drain away
Less suited to:
- A standalone base, since it does not pack hard without fines
- Paver setting beds
- Walk paths meant for strollers or wheelchairs
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of #57 stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 10x20 area at 2 inches takes about 1.7 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
