Coverage by depth
Area (sq ft) = cubic feet ÷ (depth in inches ÷ 12). One cubic yard is 27 cubic feet.
| Depth | 1 ton covers (sq ft) | 1 cu yd covers (sq ft) | 1 ton covers (m²) |
|---|---|---|---|
| 1 in | 207 | 324 | 19.3 |
| 2 in | 104 | 162 | 9.6 |
| 3 in | 69 | 108 | 6.4 |
| 4 in | 52 | 81 | 4.8 |
| 6 in | 35 | 54 | 3.2 |
| 8 in | 26 | 40 | 2.4 |
| 12 in | 17 | 27 | 1.6 |
Ton figures use 1.56 tons per cubic yard of stone dust.
Plan for settling
Stone dust is usually a thin leveling or bedding layer; use the depth on your plan. Loose material settles once it is walked on or compacted, so order a little more than the bare volume. Rochester Concrete Products' install guide adds 10% for compaction and uneven ground.
