18 Cubic Yards of Decomposed Granite in Tons
18 cubic yards of decomposed granite in tons works out to about 24.3 tons using a planning weight of 1.35 tons per yard. Real loads land between roughly 22.5 and 26.1 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 × 1.25 = 22.5 tons.
- High end: 18 × 1.45 = 26.1 tons.
If your supplier quotes a different weight per yard, multiply by theirs.

About decomposed granite
DG should be laid in thin lifts, wetted and compacted. Loose DG at a deep depth stays soft and tracks onto shoes.
Hauling 18 yards
At about 24.3 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 decomposed granite 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 decomposed granite
Best suited to:
- Garden paths and patios with a natural look
- Around trees and in xeriscape designs
- Stabilized DG for accessible paths
Think twice for:
- Steep grades without a stabilizer
- Areas right outside doors, since fines track in
- Driveways with heavy turning traffic
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of decomposed granite (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 15x30 area at 3 inches takes about 5.6 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- 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.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
