Frequently Asked Questions
How many bags of mulch equal a cubic yard?
Most bagged mulch comes in 2 cubic foot bags. Since there are 27 cubic feet in a cubic yard, you'll need about 13.5 bags to equal one cubic yard. We recommend buying 14 bags to ensure you have enough.
Should I order exactly what the calculator shows?
We recommend ordering 10% more than calculated to account for compaction, settling, and measurement variations. This extra material ensures you won't run short during your project.
What if my area has an irregular shape?
Break irregular areas into multiple rectangles or triangles, calculate each separately, and add them together. Our calculator supports multiple areas for this purpose.
