Rubber Mulch Calculator

A playground needs 6 inches of rubber mulch for a 6-foot fall height, which is about 40 bags (0.8 cu ft each) per 100 square feet.

Rubber mulch is bought bagged far more often than in bulk. Playground depth is set by fall height, not looks — 6 inches is the common minimum under equipment.

Rubber mulch questions people actually ask

How deep should rubber mulch be for a playground?
Six inches for a fall height up to 6 feet, and 9 inches for taller equipment. Decorative beds only need 2 to 3 inches.
How many bags of rubber mulch per square foot?
At 6 inches deep, a 0.8 cubic foot bag covers about 1.6 square feet, so plan on roughly 40 bags per 100 square feet.
Does rubber mulch need landscape fabric?
Yes. Fabric keeps the rubber from mixing into the soil, which makes it far easier to top up or remove years later.
