Convert volume in cubic feet to coverage area in square feet at a given depth. Find out how much area your material will cover.
If depth is in inches, divide by 12 first to convert to feet.
27 cubic feet (1 yard) at 3 inches deep:
27 / (3/12) = 27 / 0.25
= 108 square feet
| Depth | 1 Cubic Yard Covers | 1 Cubic Foot Covers |
|---|---|---|
| 1 inch | 324 sq ft | 12 sq ft |
| 2 inches | 162 sq ft | 6 sq ft |
| 3 inches | 108 sq ft | 4 sq ft |
| 4 inches | 81 sq ft | 3 sq ft |
| 6 inches | 54 sq ft | 2 sq ft |
| 12 inches | 27 sq ft | 1 sq ft |
Not directly, because they measure different things (volume vs area). You need to specify the depth to convert between them.
Common depths: Mulch 2-4 inches, Gravel 2-6 inches, Topsoil 2-4 inches, Concrete 4-6 inches. Check your project requirements.
A 2 cubic foot bag covers 12 sq ft at 2 inches, 8 sq ft at 3 inches, or 6 sq ft at 4 inches deep.
First calculate how much volume you have, then use this calculator with your desired depth to find how much area it covers. Adjust depth if needed to cover your area.
Yes, materials like mulch and topsoil can settle 10-20%. Spread slightly thicker initially, or plan to top off after settling.
1 cubic yard = 27 cubic feet. At 3 inch depth: 1 cu yd covers 108 sq ft, so 1 cu ft covers 4 sq ft (108/27).
