18 Cubic Yards of Sand in Tons
18 cubic yards of sand in tons works out to about 24.3 tons using a planning weight of 1.35 tons per yard. Real loads land between roughly 23.4 and 27.0 tons depending on stone size, fines and moisture. That is about 48,600 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 18 × 1.35 = 24.3 tons.
- Low end: 18 × 1.3 = 23.4 tons.
- High end: 18 × 1.5 = 27.0 tons.
Quarries can tell you the weight per yard for their own product; use it if you have it.

About sand
For paver bedding, concrete sand (coarse, washed) is the usual pick. Mason sand is finer and used in mortar and play areas.
Hauling 18 yards
Plan the delivery around 24.3 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 sand 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 sand
Best suited to:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Think twice for:
- Driveway bases, since sand shifts under load
- Steep areas exposed to runoff
- Thick layers under pavers, which settle unevenly
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of sand (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 12x24 area at 2 inches takes about 2.4 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
