How Much Does 7 Tons of Decomposed Granite Cover?
How much does 7 tons of decomposed granite cover depends on how deep you spread it. At about 1.35 tons per cubic yard, 7 tons is roughly 5.2 cubic yards. Spread 3 inches deep, that covers about 560 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 7 ÷ 1.35 = 5.2 yd³.
- Cubic yards to cubic feet: × 27 = 140 cu ft.
- Divide by depth in feet: at 3 inches (0.250 ft), 140 ÷ 0.250 = 560 sq ft.
Coverage of 7 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 840 | 93 |
| 3 in | 560 | 62 |
| 4 in | 420 | 47 |
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 7 tons looks like on site
For delivery, 7 tons usually fits on one smaller dump truck. 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.
Good and poor uses for decomposed granite
Good uses:
- 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 12x24 area at 3 inches takes about 3.6 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- 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.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
