40 Cubic Yards of Decomposed Granite in Tons
40 cubic yards of decomposed granite in tons works out to about 54.0 tons using a planning weight of 1.35 tons per yard. Real loads land between roughly 50.0 and 58.0 tons depending on stone size, fines and moisture. That is about 108,000 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 40 × 1.35 = 54.0 tons.
- Low end: 40 × 1.25 = 50.0 tons.
- High end: 40 × 1.45 = 58.0 tons.
The scale ticket on delivery day is the final word on weight.

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 40 yards
At about 54.0 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 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.
Where decomposed granite fits
Good uses:
- Garden paths and patios with a natural look
- Around trees and in xeriscape designs
- Stabilized DG for accessible paths
Poor fit 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 10x20 area at 2 inches takes about 1.7 tons.
- Weight used here: about 1.35 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.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.

Either works; just convert with the supplier’s own weight per yard so the two quotes compare fairly.
