7 Cubic Yards of Road Base in Tons
7 cubic yards of road base in tons works out to about 10.5 tons using a planning weight of 1.5 tons per yard. Real loads land between roughly 9.8 and 11.5 tons depending on stone size, fines and moisture. That is about 21,000 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 7 × 1.5 = 10.5 tons.
- Low end: 7 × 1.4 = 9.8 tons.
- High end: 7 × 1.65 = 11.5 tons.
Quarries can tell you the weight per yard for their own product; use it if you have it.

About road base
Road base is meant to be compacted at close to the right moisture. Dry base rock does not lock up well; a light spray of water before rolling helps.
Hauling 7 yards
Plan the delivery around 10.5 tons: one tandem 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 road base 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 road base
Best suited to:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Poor fit for:
- Drainage layers
- Decorative surfaces
- Surfaces that will stay uncompacted
Quick reference numbers
- Per inch over 100 sq ft: about 0.46 tons of road base (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.6 tons.
- Another size for comparison: a 15x30 area at 2 inches takes about 4.2 tons.
- Weight used here: about 1.5 tons per cubic yard.
Common estimating mistakes
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- 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.
