Rubber Mulch Calculator - How Much Do I Need?
Rubber mulch is a long-lasting, low-maintenance solution for everything from playgrounds to garden beds. But before you start dumping bags into your yard, it’s important to know exactly how much you’ll need. Our Rubber Mulch Calculator helps you figure out the right amount in cubic feet, pounds, pallets, and total cost — based on the area and depth of your project.
When Should You Use Rubber Mulch?
Rubber mulch is a great choice when you need long-lasting, low-maintenance ground cover that won’t break down or blow away like wood mulch. It’s ideal for playgrounds, where it provides superior impact protection; for walkways and trails, where it creates a soft, non-slip surface; and for dog runs or animal areas, thanks to its fast drainage and odor resistance. It also works well in landscaping beds, offering a clean, weed-resistant look that holds up in harsh weather. Because it doesn’t decompose, rubber mulch is a smart, cost-effective option for high-traffic or commercial spaces that need durable, reliable coverage.

FAQs
Yes, rubber mulch can be used in garden beds and around trees. It helps suppress weeds and retain soil moisture without attracting pests, although it doesn't break down to add nutrients like organic mulch does.
Rubber mulch is generally considered safe for children and animals when installed correctly. It provides cushioning for play areas and won’t harbor bugs or mold. Always use mulch certified for playground use if safety is a concern.
