Volume and tonnage calculator →Decomposed granite for 2,500 sq ft by depth
| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 2 in | 15.43 | 20.8 | 22.9 |
| 3 in | 23.15 | 31.3 | 34.4 |
| 4 in | 30.86 | 41.7 | 45.8 |
Working it out
- 2,500 sq ft × (3 ÷ 12) ft = 625.0 cubic feet.
- ÷ 27 = 23.15 cubic yards.
- × 1.35 tons per yard = 31.3 tons.
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. Typical weight: 1.25 to 1.45 tons per cubic yard.
Ordering checklist
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. Bulk delivery is the practical choice here.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
When to choose decomposed granite
Good uses:
- 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 20x25 area at 4 inches takes about 8.3 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.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- 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.
