Calculate how many square feet a given amount of cubic yards will cover at different depths. Perfect for planning mulch, gravel, and topsoil coverage.
| Cubic Yards | 2 inch depth | 3 inch depth | 4 inch depth | 6 inch depth |
|---|---|---|---|---|
| 1 cu yd | 162 sq ft | 108 sq ft | 81 sq ft | 54 sq ft |
| 2 cu yd | 324 sq ft | 216 sq ft | 162 sq ft | 108 sq ft |
| 3 cu yd | 486 sq ft | 324 sq ft | 243 sq ft | 162 sq ft |
| 5 cu yd | 810 sq ft | 540 sq ft | 405 sq ft | 270 sq ft |
| 10 cu yd | 1,620 sq ft | 1,080 sq ft | 810 sq ft | 540 sq ft |
It depends on depth. At 3 inches deep, 1 cubic yard covers 108 square feet. At 4 inches deep, it covers 81 square feet. The formula is: (27 cu ft x 12) / depth in inches.
For weed control and moisture retention, 2-4 inches is ideal. Use 2 inches for fine mulch, 3-4 inches for coarse mulch. Do not pile mulch against tree trunks or plant stems.
It varies: Mulch weighs about 400-800 lbs/yd, Topsoil 2,000-2,700 lbs/yd, Gravel 2,400-3,000 lbs/yd, Concrete about 4,000 lbs/yd.
Yes, add 5-10% extra for irregular surfaces, spillage, and compaction. Its better to have a little extra than to run short.
Break your area into rectangles and triangles. Measure length x width for each section, then add them together. Use our Square Footage Calculator for help.
2-3 inches provides good weed suppression and moisture retention while using less material. Going thicker than 4 inches can prevent water from reaching plant roots.
