How Much Rubber Mulch Do You Need?
To find how much rubber mulch you need, multiply your area by the depth for cubic feet, then divide by the coverage of one bag. Rubber mulch bags vary by brand, so check the bag, but a common figure is about 0.8 cubic feet per bag. A 10 by 10 foot area at 3 inches deep is 25 cubic feet, around 31 bags at that coverage. The calculator lets you set the bag size for accuracy.
How Deep Should Rubber Mulch Be?
Rubber mulch is usually applied 2 to 3 inches deep for landscaping, and deeper, often 3 to 6 inches, under playground equipment for fall protection. Because rubber mulch does not break down, you rarely need to top it up, so the initial depth is what matters. Set the depth in the calculator to match your use, since playground depth needs much more material than a decorative bed.
