30 Cubic Yards of #57 Stone in Tons
30 cubic yards of #57 stone in tons works out to about 40.5 tons using a planning weight of 1.35 tons per yard. Real loads land between roughly 39.0 and 43.5 tons depending on stone size, fines and moisture. That is about 81,000 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 30 × 1.35 = 40.5 tons.
- Low end: 30 × 1.3 = 39.0 tons.
- High end: 30 × 1.45 = 43.5 tons.
If your supplier quotes a different weight per yard, multiply by theirs.

About #57 stone
#57 stone is a clean crushed stone in roughly the 1/2 to 1 inch range with very few fines. It drains fast, which suits drainage layers and the top of a gravel drive, but it does not pack into a hard crust by itself.
Hauling 30 yards
Plan the delivery around 40.5 tons: two or more trucks in most areas. 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.
When to choose #57 stone
Works well for:
- French drains and drainage layers
- The top course of a gravel driveway
- Under sheds where water needs to drain away
Poor fit for:
- 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 8x16 area at 4 inches takes about 2.1 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.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
