| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 2 in | 4.94 | 6.7 | 7.3 |
| 3 in | 7.41 | 10.0 | 11.0 |
| 4 in | 9.88 | 13.3 | 14.7 |
Working it out
- 800 sq ft × (3 ÷ 12) ft = 200.0 cubic feet.
- ÷ 27 = 7.41 cubic yards.
- × 1.35 tons per yard = 10.0 tons.
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. Most suppliers will quote 1.25 to 1.45 tons per yard for this material.
Before the truck comes
- 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
Works well for:
- 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 15x30 area at 2 inches takes about 3.8 tons.
- Weight used here: about 1.35 tons per cubic yard.
Common estimating mistakes
- 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.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
