How Many Dryer Balls to Use
You know that satisfying noise your dryer makes? That’s physics. The thumping sound is actually good news. It means your balls are hitting the fabric, which is what shortens drying time by up to 25%.
So, if you hear a gentle, rhythmic bam-bam-bam, don’t worry. That’s your load getting softer by the second. If it sounds like a rock concert, you probably have one too many balls in there. Dial it back to five.

What About Wool vs. Plastic?
Wool balls are the classics—they’re soft, natural, and great at absorbing a little moisture. Plastic balls with nubs are more aggressive and better for tough loads like jeans or heavy towels. The number rule applies to both.
But wool balls tend to hold their shape longer, so you might need just three or four to get the same effect as five plastic ones. Experiment a little! It’s the most low-stakes science experiment you’ll ever run.
