Indoor vs Outdoor Pickleball Balls: The Actual Difference
Quick answer: Outdoor balls have around 40 small holes, harder plastic and more weight so wind does not push them around. Indoor balls have around 26 larger holes, softer plastic and a lighter feel with less bounce. Using the wrong one is not illegal — it just plays badly.
Most people discover this the day their outdoor ball turns their indoor game into a pinball machine. Here is the difference, plainly.
Side by side
| Outdoor | Indoor | |
|---|---|---|
| Holes | ~40, smaller | ~26, larger |
| Plastic | Harder, denser | Softer, more flexible |
| Weight | Slightly heavier | Slightly lighter |
| Bounce | Livelier, faster off the paddle | Softer, slower |
| Noise | Louder “pop” | Noticeably quieter |
| Wears out by | Cracking (especially in cold) | Going soft / out of round |
Why the design differs
Outdoor balls fight wind. More mass and smaller holes mean less deflection on a breezy court, and harder plastic survives rough asphalt — at the cost of cracking when it gets cold. Indoor balls play on smooth gym floors with no wind, so they can be softer and lighter, which produces longer rallies and a much quieter game. That noise difference matters more than you would think: it is the single biggest complaint neighbours have about backyard courts.
Which do you actually need?
- Playing outside on asphalt or a tennis conversion? Outdoor. This is most casual players.
- Playing in a gym or community centre? Indoor.
- Both? Own both. They are $10–15 for a multipack — the cheapest gear decision in the sport.
If you are buying your first setup, get a set that already includes balls so you can play on day one — Lymexa's Court Set ($59) includes two, and our starter-set comparison covers the wider field.
When to retire a ball
Outdoor balls crack — once they do, replace them; a cracked ball flies unpredictably and can be a hazard. Indoor balls rarely crack but go soft and out of round, which you will feel as a dead, unpredictable bounce. Either way, a ball that has visibly changed shape is done.
Frequently asked questions
Can you use outdoor pickleballs indoors?
You can, but they bounce faster, play harder and are considerably louder in an enclosed gym. Rallies get shorter and the game feels less controlled.
How many holes does a pickleball have?
Outdoor balls typically have around 40 smaller holes; indoor balls have around 26 larger ones. The hole pattern is the fastest way to tell them apart.
How long do pickleballs last?
It depends entirely on surface and play frequency. Outdoor balls on rough asphalt may crack within a few sessions, especially in cold weather; indoor balls last longer but eventually soften and lose their round shape.
