How Much Decomposed Granite for 200 Square Feet?
How much decomposed granite for 200 square feet depends on depth. At 3 inches you need about 1.85 cubic yards, roughly 2.5 tons at 1.35 tons per yard. At 2 inches the order drops to 1.7 tons.

| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 2 in | 1.23 | 1.7 | 1.8 |
| 3 in | 1.85 | 2.5 | 2.8 |
| 4 in | 2.47 | 3.3 | 3.7 |
Working it out
- 200 sq ft × (3 ÷ 12) ft = 50.0 cubic feet.
- ÷ 27 = 1.85 cubic yards.
- × 1.35 tons per yard = 2.5 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. Typical weight: 1.25 to 1.45 tons per cubic yard.
Getting the order right
- 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.
Good and poor uses for decomposed granite
Works well for:
- 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 8x16 area at 2 inches takes about 1.1 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.
- 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.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
