Calculate how much area mulch covers based on cubic yards or bags, with adjustable depth for garden beds and landscaping.
Enter cubic yards and depth to see how many square feet mulch covers.
Divide cubic feet by depth in feet to get square feet of coverage. One cubic yard of mulch covers 162 square feet at 2 inches deep.
At 2 inches deep, 1 cubic yard covers 162 square feet. At 3 inches, it covers 108 square feet. At 4 inches, 81 square feet. Deeper application means less coverage area.
A standard 2 cubic foot bag of mulch covers 12 square feet at 2 inches deep. You need about 13.5 bags to equal one cubic yard of bulk mulch.
Measure your beds and use the calculator to determine coverage. Compare bulk pricing vs bagged pricing. Bulk is almost always cheaper for areas over 200 square feet.
At 2 inches deep, 1 cubic yard of mulch covers about 162 square feet. At 3 inches, about 108 square feet.
