Bag counts are always rounded up
13.5 bags isn't a thing you can buy. Bag counts in the table round up to the next whole bag. The mulch bag calculator does this automatically — you'll see both the exact bag count and the rounded-up figure.
USDA Forest Service field data on shredded hardwood landscape mulches suggests an installed-volume settling rate of 15–25% within the first growing season, which is why most landscape practitioners add a 10% buffer on top of the bag or yard count derived directly from area × depth math.
When to switch from bags to bulk
Once you need more than 3 cubic yards (about 41 bags of 2 cu ft), bulk delivery wins on price by 30–50% even after the delivery fee. Below 3 yards, bagged is usually faster and cheaper. Right at 1–2 yards is a judgment call based on your truck and store proximity.

Frequently asked questions
How many 2 cu ft bags equal 1 cubic yard?+
13.5 bags. One cubic yard contains 27 cubic feet, and 27 ÷ 2 = 13.5. Round up to 14 since stores don't sell partial bags.
How many 3 cu ft bags equal 1 cubic yard?+
9 bags exactly. 27 ÷ 3 = 9. Three-cubic-foot bags make the math cleaner, which is one reason landscapers prefer them.
What about partial yards — like 0.5 cu yd?+
0.5 cu yd = 13.5 cu ft = 7 bags of 2 cu ft or 5 bags of 3 cu ft (rounded up). The mulch calculator handles fractional yards automatically.
