How to Calculate How Much Mulch You Need

Here’s how simple it is:

Measure your space – Grab a tape measure and get the length and width (in any unit mentioned in the calculator) of the area you want to mulch.
Choose your desired depth – A typical mulch depth is:
- 2 inches for fine mulch
- 3 inches for medium mulch (most common)
- 4 inches for coarser mulch or to suppress weeds
Plug the numbers into our calculator above – you’ll instantly see how many cubic feet or cubic yards of mulch you need.

Why Using the Right Amount of Mulch Matters

Mulch isn’t just for looks—it helps your plants retain moisture, reduce weeds, and regulate soil temperature. But using too little won’t get the job done, and too much can suffocate your plants. That’s why it’s important to calculate mulch correctly before you start.
