Convert area in square feet to volume in cubic yards for ordering bulk materials. Calculate how many yards of mulch, gravel, topsoil, or concrete you need.
| Depth | 1 Cubic Yard Covers | Yards Needed for 1000 sq ft |
|---|---|---|
| 1 inch | 324 sq ft | 3.09 cu yd |
| 2 inches | 162 sq ft | 6.17 cu yd |
| 3 inches | 108 sq ft | 9.26 cu yd |
| 4 inches | 81 sq ft | 12.35 cu yd |
| 6 inches | 54 sq ft | 18.52 cu yd |
| 12 inches (1 ft) | 27 sq ft | 37.04 cu yd |
Multiply square feet by depth (in feet), then divide by 27. Formula: (Area in sq ft x Depth in ft) / 27 = Cubic Yards. If depth is in inches, divide by 12 first.
At 3 inches deep, 1 cubic yard covers about 108 square feet. At 4 inches deep, it covers about 81 square feet. Coverage decreases as depth increases.
Yes, always round up and add 5-10% extra for settling, compaction, and irregularities in the ground surface. For decorative materials, add 10-15%.
Break irregular areas into smaller rectangles or triangles, calculate each separately, then add them together. For the total square footage, then enter it in this calculator.
Bulk is usually more economical for orders over 2-3 cubic yards. Bagged materials are convenient for small projects and easy handling but cost more per cubic yard.
Delivery ranges from $50-150 depending on distance and quantity. Many suppliers offer free delivery over a certain yardage (often 5+ yards).
