You can think of a “yard of mulch” as a volume: one cubic yard equals 27 cubic feet.

Most bagged mulch is sold in a few standard sizes, so the number of bags in a yard depends on bag size:

  • 1 cubic foot bags: about 27 bags per yard.
  • 1.5 cubic foot bags: about 18 bags per yard.
  • 2 cubic foot bags (most common): about 13.5–14 bags per yard (many guides round up to 14).
  • 3 cubic foot bags: 9 bags per yard.

In practical terms, if your mulch comes in 2 cubic foot bags, you’ll usually buy 14 bags to equal roughly one yard.
