How Many Square Feet Does a Yard of Concrete Cover?
Part of Concrete & Masonry
Quick answer
A cubic yard covers 81 ft² at 4 inches thick, 65 ft² at 5 inches, and 54 ft² at 6 inches. Coverage = 324 ÷ thickness in inches.
Because a cubic yard is a fixed volume (27 ft³), the area it covers depends on how thick you pour. Spread it thinner and it covers more area.
| Thickness | Coverage per yard |
|---|---|
| 3 in | 108 ft² |
| 4 in | 81 ft² |
| 5 in | 65 ft² |
| 6 in | 54 ft² |
Shortcut: coverage in ft² = 324 ÷ thickness in inches.
