How Many Bags of Mulch Are in a Yard? (13.5, and When Bulk Wins)
One cubic yard of mulch equals 13.5 standard bags. A yard is 27 cubic feet and the standard bag holds 2, so the division is exact. Big-box stores also sell 3-cubic-foot bags (9 per yard) and small 1.5-cubic-foot bags (18 per yard). That one conversion decides the bagged-or-bulk question on every mulch run, so here’s the whole math.
Bags per yard, by bag size
| Bag size | Bags in one cubic yard | Common at |
|---|---|---|
| 1.5 cu ft | 18 | Discount stores, colored mulch |
| 2 cu ft | 13.5 | The standard almost everywhere |
| 3 cu ft | 9 | Pine bark, premium hardwood |
The break-even math
Say bagged mulch runs $4 a bag on sale and the bulk yard sells the same hardwood for $35 a yard plus $60 delivery. Bagged, a yard costs 13.5 x $4 = $54. One bulk yard costs $95 delivered, but the second yard costs $35. So: one yard, bags win. Two yards, it’s $108 in bags against $130 bulk, still close. Three yards and up, bulk wins and keeps winning. The crossover on typical prices sits right around 2 to 3 yards, lower if your store’s bags aren’t on sale.
Two non-price factors worth weighing: bags are clean, stackable, and spread over a weekend without a driveway pile; bulk is one big shovel-it-now event but far less plastic in the trash.
How much mulch the beds actually need
Coverage per yard: about 160 square feet at 2 inches deep, 108 at 3 inches. Established beds want a total depth of 2 to 3 inches; more suffocates roots and invites stem rot where mulch piles against plants. If there’s already an inch on the bed, you’re topping up an inch, not starting over, and the order drops by half.

A real yard, worked
Three beds: 30 x 4, 25 x 3, and 15 x 5, which is 270 square feet total. At 3 inches deep that’s 67.5 cubic feet, or 2.5 yards, which is 34 standard bags. On the math above, that’s the zone where bulk starts to win: about $148 in bags against $148 delivered bulk at our sample prices, a coin flip on cost, so pick on convenience. At 4 beds or a spring-and-fall schedule, bulk pulls ahead clearly.

Buying notes
- Weight check: a 2-cubic-foot bag of hardwood mulch weighs about 20 pounds dry and 30-plus wet. A yard of mulch runs 600 to 800 pounds, one of the few bulk products a half-ton pickup carries comfortably.
- Watch the bag size on sales. The loss-leader bags are often 1.5 cubic feet, which quietly moves the per-yard price.
- Bulk yards sell by the half yard. Order 2.5 if the math says 2.5; you’re not stuck rounding to whole yards.
- Keep mulch 2 to 3 inches off tree trunks and stems. The volcano look kills trees slowly.
How much does a yard of mulch cost?
Bulk hardwood mulch runs $30 to $60 a yard at most yards, with dyed black and brown at the top of that range and premium products above it:
| Mulch type | Per yard, bulk | Per 2 cu ft bag |
|---|---|---|
| Shredded hardwood | $30 – $45 | $3 – $4 |
| Dyed (black, brown, red) | $40 – $60 | $3.50 – $5 |
| Cedar | $45 – $70 | $5 – $7 |
| Pine bark nuggets | $40 – $60 | $5 – $6 (3 cu ft) |
| Playground certified | $45 – $65 | $6 – $7 |
Delivery adds $40 to $100 per trip, which is why the bagged-versus-bulk crossover sits around 2 to 3 yards rather than at one.
How many bags of mulch do I need?
Square feet times depth in inches, divided by 24, gives 2-cubic-foot bags directly (each bag covers 12 square feet at 2 inches). Common beds:
| Bed | At 2 in deep | At 3 in deep |
|---|---|---|
| 4 x 25 ft border (100 sq ft) | 9 bags | 13 bags |
| 10 x 20 ft bed (200 sq ft) | 17 bags | 25 bags |
| 500 sq ft of beds | 42 bags | 63 bags |
| 1,000 sq ft of beds | 84 bags / 6.2 yd | 125 bags / 9.3 yd |
Once the count crosses about 30 bags, you’re carting a literal ton of plastic-wrapped mulch; that’s the bulk line. The mulch calculator runs both units against your real bed sizes.
Quick answers
How many 3 cubic foot bags in a yard? Nine. The big bags shift the bagged math: at $5 a bag that’s $45 a yard, close enough to bulk that convenience can win on mid-size jobs.
How many bags of mulch on a pallet? Usually 45 to 70 of the 2-cubic-foot size depending on the store, which is 6.7 to 10 yards per pallet. Spring sales often price a full pallet below the same mulch in bulk.
How much does 2 yards of mulch cover? About 325 square feet at 2 inches deep, or 215 at 3 inches. Two yards is the classic front-yard refresh order.
When should I mulch? Late spring after soil warms, and optionally a thin fall top-up. Mulching cold spring soil slows the bed down; mulching in fall protects roots through freeze-thaw.
