Mulch Bag Calculator
Estimate cubic yards of mulch and convert the volume into two-cubic-foot bags for garden beds, borders, tree rings, and landscaping.
Quick reference: One cubic yard equals 27 cubic feet, or 13.5 bags that each hold 2 cubic feet. Round up to 14 bags before adding overage.

Mulch Planning Tips
- Measure the bed after edging so the area reflects the actual space to cover.
- Use 2 inches for a light refresh and 3 inches for a new layer.
- Keep mulch away from direct contact with tree trunks and building siding.
- Compare bagged and bulk pricing after accounting for delivery.
