3 Cubic Yards of Crushed Stone in Tons
3 cubic yards of crushed stone in tons works out to about 4.2 tons using a planning weight of 1.4 tons per yard. Real loads land between roughly 4.1 and 4.5 tons depending on stone size, fines and moisture. That is about 8,400 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 3 × 1.4 = 4.2 tons.
- Low end: 3 × 1.35 = 4.1 tons.
- High end: 3 × 1.5 = 4.5 tons.
Quarries can tell you the weight per yard for their own product; use it if you have it.

About crushed stone
Crushed stone has fractured faces, so the pieces interlock when compacted. That is why it holds a driveway or pad shape better than round stone of the same size.
Hauling 3 yards
Plan the delivery around 4.2 tons: one small truck 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 crushed 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 crushed stone fits
Best suited to:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Think twice for:
- Barefoot areas, since angular stone is rough
- Play areas
- Places that need a smooth rolling surface for wheels
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 8x16 area at 2 inches takes about 1.1 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
