Coverage of one cubic yard at different depths
At 1 inch deep, one cubic yard covers 324 square feet. At 2 inches, 162 square feet; at 3 inches, 108; at 4 inches, 81; at 6 inches, 54; and at 12 inches, 27 square feet.
The values assume uniform thickness and disregard settling, waste and compaction.
How to use the coverage formula
Multiply your cubic yards by 324, then divide by desired depth in inches. Example: 2 cubic yards at 3 inches deep cover approximately 216 square feet.
Where coverage charts are helpful
Coverage is useful for planning mulch beds, topsoil dressing, gravel walks and other uniform layers. For a variable-depth installation, divide into sections or use an appropriate average depth supported by measurements.
Why actual material coverage may vary
Surface irregularities, compaction, settling and spreading technique affect real-world application. A delivery volume should not be confused with a guaranteed finished coverage area.
