5 Cubic Yards of River Rock in Tons
5 cubic yards of river rock in tons works out to about 6.8 tons using a planning weight of 1.35 tons per yard. Real loads land between roughly 6.2 and 7.2 tons depending on stone size, fines and moisture. That is about 13,500 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 5 × 1.35 = 6.8 tons.
- Low end: 5 × 1.25 = 6.2 tons.
- High end: 5 × 1.45 = 7.2 tons.
If your supplier quotes a different weight per yard, multiply by theirs.

About river rock
River rock is mostly decorative and for drainage beds. It is not meant to be driven on and tends to roll if used as a walking surface.
Hauling 5 yards
At about 6.8 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 river rock 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 river rock fits
Good uses:
- Dry creek beds and drainage swales
- Decorative borders and planting beds
- Around downspouts to stop splash erosion
Less suited to:
- Walking surfaces
- Driveways
- Bases under slabs or pavers
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of river rock (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 20x25 area at 3 inches takes about 6.3 tons.
- Weight used here: about 1.35 tons per cubic yard.
Common estimating mistakes
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
