13.5 mulch bags equal one cubic yard
A cubic yard of mulch covers 27 cubic feet. Since most mulch bags hold 2 cubic feet, you need 13.5 bags to make one cubic yard. For 3-cubic-foot bags, you'd need 9 bags per yard.
Mulch bag quantities per cubic yard
| Bag Size | Bags per Cubic Yard | Total Coverage (2" depth) |
|---|---|---|
| 2 cubic feet | 13.5 bags | 162 sq ft |
| 2.5 cubic feet | 10.8 bags | 162 sq ft |
| 3 cubic feet | 9 bags | 162 sq ft |
Calculating mulch needs
- Measure area: Length × Width = Square footage
- Determine depth: 2-3 inches typical for mulch
- Calculate volume: Square footage × Depth (in feet)
- Convert to yards: Divide cubic feet by 27
Cost comparison by bag size
- 2-cubic-foot bags: Most common, easier to handle
- 2.5-cubic-foot bags: Better value per cubic foot
- 3-cubic-foot bags: Fewer bags to transport, cost-effective
