How Much Does 10 Tons of Decomposed Granite Cover?
How much does 10 tons of decomposed granite cover depends on how deep you spread it. At about 1.35 tons per cubic yard, 10 tons is roughly 7.4 cubic yards. Spread 3 inches deep, that covers about 800 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 10 ÷ 1.35 = 7.4 yd³.
- Cubic yards to cubic feet: × 27 = 200 cu ft.
- Divide by depth in feet: at 3 inches (0.250 ft), 200 ÷ 0.250 = 800 sq ft.
Coverage of 10 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 1,200 | 133 |
| 3 in | 800 | 89 |
| 4 in | 600 | 67 |
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.
Putting 10 tons to use
For delivery, 10 tons is in the range of one full tandem load. Ask the supplier how they will split it. 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.
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 14x28 area at 3 inches takes about 4.9 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
