The mulch calculator makes it easy to answer a basic question when it's time for the final touch on your landscaping job - "How much mulch do I need?" Use our mulch calculator to get the answer and save yourself from having to make another trip to the garden center!
The total amount of mulch you will need is the surface area multiplied by the thickness of the layer of mulch. This way we get the volume that needs to be filled with mulch. This is the same idea at work in the concrete calculator.
Bag sizes vary according to the type of mulch but the industry standard is two cubic feet. One cubic yard is twenty-seven cubic feet so fourteen standard bags are needed for each cubic yard.
