Why use a rubber mulch calculator
Rubber mulch is denser and applied deeper than organic bark — typically 4 to 6 inches for playground safety — so cubic yards and bag counts add up quickly. Use our mulch bag calculator for retail bag conversions.

Rubber Mulch FAQ
How much rubber mulch do I need for a playground?
Most playgrounds require 6 inches of rubber mulch for fall protection & cushioning. A 20 × 20 ft playground pad at 6 inches deep requires about 7.56 cubic yards of rubber mulch.
Does rubber mulch decompose?
No. Rubber mulch is made from recycled tires and lasts indefinitely without breaking down or absorbing moisture.
Is rubber mulch safe for landscape beds?
Rubber mulch is great for playgrounds, walkways, and non-edible landscaping beds. It suppresses weeds and retains color for years.
How many bags of rubber mulch equal a cubic yard?
A cubic yard is 27 cubic feet. With standard 2 cu ft bags, you need 14 bags per cubic yard. Our calculator converts area into both cubic yards and bag counts automatically.
