12 Cubic Yards of Gravel in Tons
12 cubic yards of gravel in tons works out to about 16.8 tons using a planning weight of 1.4 tons per yard. Real loads land between roughly 15.6 and 18.0 tons depending on stone size, fines and moisture. That is about 33,600 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 12 × 1.4 = 16.8 tons.

- High end: 12 × 1.5 = 18.0 tons.
The scale ticket on delivery day is the final word on weight.

About gravel
Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage.
Hauling 12 yards
Plan the delivery around 16.8 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 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.
Good and poor uses for gravel
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
Poor fit for:
- 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 12x24 area at 3 inches takes about 3.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- 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.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
