Enter the bed size and press Calculate.
Enter the bed's length and width (feet or meters) and how deep you want the mulch in inches. The tool computes the volume in cubic feet and cubic yards, then converts that into a bag count assuming standard 2-cubic-foot bags, so you know exactly what to buy whether you shop bagged or bulk.
Three inches is the sweet spot for most beds: enough to suppress weeds and hold moisture without suffocating plant roots. Go thinner (2 inches) around shallow-rooted plants and thicker (4 inches) on paths. The calculator works with any depth you enter.
