Calculate exactly how much mulch you need for your garden or landscaping project in cubic yards, cubic feet, and bags.
Enter your garden bed dimensions
Pro Tip: We recommend buying 10% extra mulch to account for settling and uneven areas. Always apply mulch 2–4 inches deep and keep it away from tree trunks and plant stems.
Measure the length and width (or diameter) of your garden bed in feet.
Choose your desired mulch depth. 2–3 inches is standard for most gardens.
Formula: (Area × Depth ÷ 12) ÷ 27 gives you cubic yards.
