At a glance
The Conversion
One cubic yard contains 27 cubic feet. Since the most common bagged mulch size is 2 cubic feet, one cubic yard equals 13.5 bags — so in practice you buy 14 bags to match a yard. With 3-cubic-foot bags, one yard is exactly 9 bags.

Bag-to-Yard Conversion Table
| Cubic Yards | Cubic Feet | 2 cu ft Bags | 3 cu ft Bags |
|---|---|---|---|
| 0.5 yd³ | 13.5 ft³ | 7 | 5 |
| 1 yd³ | 27 ft³ | 14 | 9 |
| 2 yd³ | 54 ft³ | 27 | 18 |
| 3 yd³ | 81 ft³ | 41 | 27 |
Bag counts are rounded up, since you cannot buy a partial bag.
When Bags Stop Making Sense
At around $4 per 2-cubic-foot bag, a cubic yard of bagged mulch costs about $54. Bulk mulch typically runs $30–$50 per cubic yard, so the crossover is immediate on price — but bulk suppliers usually require minimum orders of 2–3 yards plus a delivery fee. Under about 2 cubic yards, bags win on convenience; above that, bulk wins on cost.
Working Backward from Your Bed
Enter your bed's length, width, and depth in the calculator above to get both the cubic-yard figure and the exact bag count. For example, a 10 × 5 ft bed at 3 inches deep needs 12.5 cubic feet — just under half a yard, or 7 bags. Add 5–10% to your final number to allow for settling over the season.
Frequently Asked Questions
How many 2 cubic foot bags make a yard of mulch?
13.5 bags exactly, since a cubic yard is 27 cubic feet. Round up to 14 bags when buying to make sure you have full coverage.
How much does a cubic yard of mulch weigh?
A cubic yard of typical shredded hardwood mulch weighs roughly 400 to 800 pounds depending on moisture content — about 0.2 to 0.4 tons per yard.
Is it cheaper to buy mulch by the bag or by the yard?
Per unit of volume, bulk by the yard is almost always cheaper. Bags only make sense for small jobs under about 2 cubic yards, where delivery minimums and fees would erase the savings.
