Enter your bed size and mulch depth to get the cubic yards and the exact number of 2 cu ft bags you need — no more guessing at the garden center.
2–3 in for beds, 3–4 in to suppress weeds.
Mulch needed
0.93 cu yd
or 13 bags (2 cu ft each)
1 cu yd = 27 cu ft = 13.5 bags of 2 cu ft mulch. Counts round up so you never come up short. Order ~10% extra for settling and uneven beds.
Mulch is sold by volume, not area, so you need three numbers: the length and width of the bed (or its total square footage) and how deep you want the mulch. The math is straightforward:

Bagged mulch is easy to haul in a car and simple to price, but it gets expensive fast on big jobs. Because a cubic yard is 13.5 bags of 2 cubic foot mulch, anything past roughly 8 to 10 bags is usually cheaper delivered in bulk. For a pro crew mulching several properties a week, bulk almost always wins on both price and time. Pricing the job itself?

Depth drives everything. Two to three inches suits most beds, while three to four inches better suppresses weeds and holds moisture. Because coverage is 324 divided by the depth in inches, one cubic yard covers about 162 sq ft at 2 inches, 108 sq ft at 3 inches, and 81 sq ft at 4 inches. Order about 10% extra for settling and uneven ground. If you are building a mulching or landscaping service, see how to start a lawn care business and how to start a landscaping business.
A cubic yard equals 27 cubic feet, so a yard of mulch is 13.5 bags of the standard 2 cubic foot size. If your bags are 3 cubic feet, a yard is 9 bags. Once you pass roughly 8 to 10 bags of 2 cubic foot mulch, ordering bulk by the yard usually costs less than buying bags.
Pallets vary by supplier, but a full pallet of 2 cubic foot bagged mulch typically holds 60 to 70 bags, which is about 120 to 140 cubic feet, or roughly 4.5 to 5 cubic yards. Always confirm the bag size and count with your supplier, since 3 cubic foot bags ship fewer per pallet.
One cubic yard is 27 cubic feet, so coverage depends on depth. At 3 inches deep a yard covers about 108 square feet, at 2 inches about 162 square feet, and at 4 inches about 81 square feet. The rule is 324 divided by the depth in inches equals the square feet one yard will cover.
Two to three inches is right for most landscape beds, and three to four inches helps suppress weeds and hold moisture. Avoid piling mulch against trunks and stems. Fresh top-ups over existing mulch usually only need one to two inches to refresh color and depth.
