Direct answer
Coverage depends entirely on depth. One cubic yard covers a broad area shallowly and a much smaller area deeply.
Use area and depth together
| Depth | Approximate coverage from 1 yd³ | Typical context |
|---|---|---|
| 1 inch | 324 sq ft | Thin amendment planning |
| 2 inches | 162 sq ft | Surface layer |
| 3 inches | 108 sq ft | Mulch planning |
| 6 inches | 54 sq ft | Shallow root-zone volume |
| 12 inches | 27 sq ft | Deep fill |
These are geometric conversions, not universal application recommendations. Use the depth appropriate to the project.
