Mulch Bag Calculator — frequently asked questions
How does this how many bags of mulch do I need calculator work?+
It calculates the bed area from the selected shape, multiplies by mulch depth in inches, converts that to cubic feet, then rounds up to whole bags. Pro can also add waste and compare 1.5, 2, and 3 cu ft bags.
How deep should mulch be?+
Most garden beds use about 2 to 3 inches of mulch. A 4-inch depth can help for new beds or weed suppression, but keep mulch away from stems, trunks, and siding.
Should I add extra mulch for waste or settling?+
A 5% to 10% buffer is common for uneven beds, settling, and measurement misses. Pro unlocks a waste percentage so the bag count and cost include that buffer.
Is my project data sent to a server?+
No. Bed dimensions, depth, waste, price, volume, and bag calculations happen entirely in your browser.
