Ever wondered why pickleball uses 2 different types of balls? Why is it even designed like that and not uniform like other sport balls? In which situation is it appropriate to use a certain type of ball?
The short answer is that indoor and outdoor pickleballs differ in hole count, hardness and weight, and each is built for a different kind of court. Let’s break it down.
Why Is a Pickleball Designed Like That?
We will first go over why the pickleball is designed like that.
The pickleball as we know it, is hollowed out with holes covering its surface, which both harmonize for function and allow for the sport of pickleball to be played. Firstly, its hollow core makes it much lighter so players don’t need extreme force or power to participate in the sport. That is not to say that power plays no function in the sport, but its importance is greatly diminished compared to sports like tennis, and technique plays a far greater role in pickleball.
In technique we see the ball’s second function. Its hole covered surface keeps the ball’s flight steady and predictable, allowing for greater control over the ball, which separates the pros from the rest who are able to use this greater range of control to make plays. These holes also serve an additional function of slowing down the ball mid air to allow pickleball to be played at a reasonable pace, since balls without holes travel faster.
The Two Types of Pickleballs
Although both balls are labeled indoor and outdoor pickleball respectively, some would say that the court matters more than the setting itself. Both really are designed for their respective spaces.
Outdoor Pickleballs
A gritty, rough surface like a tennis court calls for an outdoor pickleball, which has around 40 small holes. This makes them a bit heavier and more stable in windy environments. They are also made from harder plastic, so they last longer on rough surfaces, though they tend to sound louder and feel less forgiving off the paddle.
Indoor Pickleballs
Indoor pickleballs are lighter and have fewer holes, usually around 26 to 28, that are larger than outdoor pickleballs’. They are good for solid cement or hardwood courts. These smooth surfaces let the ball bounce and skid quickly, so the softer, lighter indoor ball helps keep the game slower and easier to control. They also make less noise, which is why many indoor facilities prefer them.
Indoor vs Outdoor Pickleball at a Glance
| Indoor | Outdoor | |
|---|---|---|
| Holes | Fewer, larger (around 26-28) | More, smaller (around 40) |
| Feel | Softer and lighter | Harder and heavier |
| Wind | Drifts easily | Holds its line |
| Sound | Quieter | Louder |
| Best for | Gyms, hardwood, smooth cement | Rough, gritty courts |
Can You Use an Outdoor Pickleball Indoors (and Vice Versa)?
Yes, you can, but expect the game to feel different. An outdoor ball indoors tends to play fast and hard to control, and it can be noisy in an echoey gym. An indoor ball outdoors can get pushed around by even a light breeze, and its softer shell can crack or wear out quickly on rough courts.
If you’re playing casually, mixing them is fine. For tournaments, check which ball is being used ahead of time, since organizers usually specify it.
How to Choose the Right Pickleball
Not sure which one to buy? Ask yourself these questions:
- Where do you play most often? This matters most. Gym or hardwood floor means indoor. Outdoor courts mean outdoor.
- Is it windy where you play? If so, the outdoor ball’s extra weight will help.
- Are you training for a tournament? Practice with the same type of ball the event will use. (Try the same brand if possible)
- Do you play near others who dislike noise? The quieter indoor ball is the friendlier choice.
If you want a ball approved for official play, look for ones on the USA Pickleball approved list.
So, pickleball may look simple, but the ball is carefully designed to make the game fun, fair, and playable for everyone. Choosing between indoor and outdoor comes down to the surface and the setting. Match your ball to your court and you’ll get a better bounce, better control, and a ball that lasts longer.
