40 cubic yards of pea gravel in tons works out to about 56.0 tons using a planning weight of 1.4 tons per yard. Real loads land between roughly 52.0 and 60.0 tons depending on stone size, fines and moisture. That is about 112,000 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 40 × 1.4 = 56.0 tons.
- Low end: 40 × 1.3 = 52.0 tons.
- High end: 40 × 1.5 = 60.0 tons.
Quarries can tell you the weight per yard for their own product; use it if you have it.

About pea gravel
Pea gravel is small, rounded stone, usually around 3/8 inch. It is comfortable to walk on and drains well, but it shifts under car tires and needs a solid edge to stay put.
Hauling 40 yards
At about 56.0 tons, this is more than one typical truckload. 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 pea 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.
When to choose pea gravel
Good uses:
- Patios, walkways and dog runs
- Play areas with proper depth and edging
- Drainage around foundations when sized properly
Less suited to:
- Driveways and steep paths, where it rolls and ruts
- Under pavers as a base
- Areas without edging
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of pea gravel (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 15x30 area at 3 inches takes about 5.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- 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.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
