How Many Bags of Mulch in a Cubic Yard? Calculation
Every spring homeowners face the annual landscaping decision. Should you order bulk mulch delivered by dump truck or buy plastic bags of mulch from your local home center? To compare pricing and volume, you need to know how many bags of mulch equal one cubic yard.
The short mathematical answer is 13.5 standard 2.0 cubic foot bags equal one cubic yard of mulch. Because stores do not sell half bags, you need to purchase 14 bags.

The Math Behind Mulch Volume Conversions
Three-dimensional volume math starts with cubic feet:
- 1 Cubic Yard = 27 Cubic Feet (3 ft x 3 ft x 3 ft = 27 cu ft)
Retail stores sell bagged mulch in several standard volume sizes. Divide 27 cubic feet by your bag size:
| Bag Size (Cu Ft) | Bag Size (Liters) | Exact Bags per Yard | Bags to Purchase |
|---|---|---|---|
| 1.5 cu ft Bag | 42.5 Liters | 27 / 1.5 = 18.0 Bags | 18 Bags |
| 2.0 cu ft Bag (Standard) | 56.6 Liters | 27 / 2.0 = 13.5 Bags | 14 Bags |
| 3.0 cu ft Bag (Large) | 85.0 Liters | 27 / 3.0 = 9.0 Bags | 9 Bags |
Bulk Mulch vs Bagged Mulch Cost Comparison
Choosing between bulk delivery and store bags usually comes down to project size and convenience:
- When Bagged Mulch Wins: For small landscaping projects requiring less than 2 cubic yards (under 27 bags). Bags fit easily in your car trunk and allow spot application around individual shrubs.
- When Bulk Mulch Wins: For large yard projects requiring 3 cubic yards or more (over 40 bags). Dump truck delivery saves significant manual labor opening individual bags.
