How Much Does 11 Tons of Decomposed Granite Cover?
How much does 11 tons of decomposed granite cover depends on how deep you spread it. At about 1.35 tons per cubic yard, 11 tons is roughly 8.1 cubic yards. Spread 3 inches deep, that covers about 880 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 11 ÷ 1.35 = 8.1 yd³.
- Cubic yards to cubic feet: × 27 = 220 cu ft.
- Divide by depth in feet: at 3 inches (0.250 ft), 220 ÷ 0.250 = 880 sq ft.
Coverage of 11 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 1,320 | 147 |
| 3 in | 880 | 98 |
| 4 in | 660 | 73 |
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. 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 11 tons looks like on site
11 tons is about one tandem-axle truck load, 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.
Where decomposed granite fits
Works well for:
- 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 8x16 area at 3 inches takes about 1.6 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.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
