How Much Does 23 Tons of Decomposed Granite Cover?
How much does 23 tons of decomposed granite cover depends on how deep you spread it. At about 1.35 tons per cubic yard, 23 tons is roughly 17.0 cubic yards. Spread 3 inches deep, that covers about 1,840 square feet. Go thinner and it covers more; go deeper and it covers less.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 23 ÷ 1.35 = 17.0 yd³.
- Cubic yards to cubic feet: × 27 = 460 cu ft.
- Divide by depth in feet: at 3 inches (0.250 ft), 460 ÷ 0.250 = 1,840 sq ft.
Coverage of 23 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 2,760 | 307 |
| 3 in | 1,840 | 204 |
| 4 in | 1,380 | 153 |
About decomposed granite
Decomposed granite (DG) is weathered granite broken into small particles and fines. It packs into a firm, natural-looking path surface, and stabilized versions include a binder. Weight runs about 1.25 to 1.45 tons per cubic yard, so treat the table as a planning range rather than an exact figure.
What 23 tons looks like on site
23 tons will usually take two or more truck loads, though legal limits vary by truck and state. Spread from the pile with a loader, skid steer or wheelbarrow, then rake to depth before compacting if the material calls for it.
- Check depth as you go. Stakes marked at the target depth help keep the spread even.
- Expect some loss. Compaction and uneven ground use more than the flat-math figure. Keep about 10 percent in reserve.
- Ask about moisture. Wet material weighs more, so a ton of it covers less.
To run your own numbers, use the volume and tonnage calculator.
Good and poor uses for decomposed granite
Best suited to:
- Garden paths and patios with a natural look
- Around trees and in xeriscape designs
- Stabilized DG for accessible paths
Less suited to:
- 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 4 inches takes about 3.3 tons.
- Weight used here: about 1.35 tons per cubic yard.
Common estimating mistakes
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- 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.
