The Complete Guide to Pickleball Balls | Coach Explains Differences Between Outdoor and Indoor Balls and How to Choose Approved Balls
"Are pickleball balls different from tennis balls?" "Should I buy indoor or outdoor balls?" These are some of the simple questions we often hear from our customers. In fact, pickleball balls come in two distinct types, and choosing the wrong ball can feel so off that it's hard to even play—this isn't unusual.
As someone who has playtested over 100 paddles, I (Coach Yoshi) will explain ball selection from the ground up, from the differences between outdoor and indoor balls to how to identify USAP-approved balls and how to choose among the standard models.
What Are Pickleball Balls Like?
Pickleball balls are completely different from tennis balls or badminton shuttlecocks; they are hollow plastic balls. They are about 74mm in diameter (slightly larger than a tennis ball) and weigh about 22–26g (less than half the weight of a tennis ball). The main materials are polyethylene and polypropylene, and they are characterized by round holes all over their surface.
These holes determine the unique feel, flight, and spin characteristics of pickleball. The difference in the number of holes is the biggest factor that separates outdoor balls from indoor balls.
| Item | Outdoor | Indoor |
|---|---|---|
| Number of holes | Around 40 | Around 26 |
| Hardness | Harder | Slightly softer |
| Main playing environment | Outdoor courts (with wind) | Indoor courts (no wind) |
| Color | Mostly neon green, yellow, and orange | A mix of white and yellow |
💡 Coach Yoshi's Tip
Some people start with plastic balls from a 100-yen store, thinking "any ball will do for now," but to be honest, USAP-approved balls and non-approved balls fly completely differently. For your first dozen (about 2 sets of 6 balls), I highly recommend choosing approved balls. You'll see a visible difference in how fast you improve.
Characteristics of Outdoor Balls
Outdoor balls are designed to minimize the effect of wind.
Design Features
- More holes (around 40): Distributes air resistance, so the trajectory is less likely to be thrown off by wind.
- Harder: Consistent bounce on outdoor hard courts. Also more durable.
Playing Feel
Outdoor balls give you the sensation of the ball firmly biting into the paddle face. When you hit a drive or a third-shot drive, you feel a solid "thwack" as the power is transferred. A big advantage is that it's easy to hit your target even on windy days.
When to Use Them
- Outdoor park courts and facilities that convert tennis courts
- Tournament qualifiers and main draws (mostly outdoors)
- Any play on windy days
Representative Models
- Franklin X-40: USAP approved. An outdoor ball used at USA Pickleball's National Championships, the US Open, and on the APP Tour. We carry it at our store, too → View the product page
- Onix Fuse Outdoor: USAP approved, highly rated for its balance of durability and feel (Note: The former "Pure 2 Outdoor" was removed from USAP approval in 2018).
- Dura Fast 40: USAP approved, a long-established classic. It was the official ball of the PPA Tour through 2023.
- Engage Neon Tour Ball 2.0: USAP approved, 40 holes. Its high-visibility neon green and newly developed polymer material deliver stable flight and durability in both hot and cold conditions. It also features a low-vibration, quiet design.
Characteristics of Indoor Balls
Indoor balls are designed for delicate control in environments without wind.
Design Features
- Fewer holes (around 26): Less air resistance, so it flies straighter.
- Slightly softer: Consistent bounce on indoor gym floors and wooden courts.
Playing Feel
Indoor balls have a sensation of the ball sitting softly on the paddle. They feel milder than outdoor balls, making it easier to be precise with dinks and drop shots. However, if you use them outdoors, the wind carries them far off their line, which makes it harder to put them where you're aiming.
When to Use Them
- Indoor gyms and sports centers
- Home garages and community centers
- Outdoor courts on days with no wind (can also be used in place of outdoor balls)
Representative Models
- Onix Fuse Indoor: USAP approved, the standard ball widely used at indoor tournaments.
- Jugs Indoor: Indoor-only, known for its soft feel.
- Gamma Photon Indoor: USAP approved, popular for its high-visibility color.
How to Identify USAP-Approved Balls
Pickleball balls are covered by USA Pickleball (USAP)'s approval program. If you're playing in a match or an official practice session, always choose an approved ball.
Checkpoints for Approved Balls
- The ball itself or its packaging is marked "USA Pickleball Approved"
- The model can be found on the official list (USAP Approved Ball List)
- Diameter, weight, bounce, compression (how much it squashes), and number of holes are within the official specifications (hardness is only recorded for reference and is not a pass/fail condition)
Risks of Using Non-Approved Balls
- Unstable flight: Non-standard hole placement or weight balance causes unexpected behavior.
- Low durability: May crack after just 1–2 matches.
- Not allowed in matches: Can't be used at tournaments that require approved balls.
I've covered the numbers behind the approved-ball specifications and how the pro tours' official balls have changed over the years in The Pickleball Ball Wars.
💡 Coach Yoshi's Tip
In Japan, some people buy cheap balls from 100-yen stores or Amazon "just because they're cheap." They're fine for light practice, but once you reach the stage where you want to improve your spin and drop shot accuracy, be sure to switch to approved balls. Even if you make the same movements, the ball behaves differently, so the technique won't stick.
Ball Buying Checklist
Here are 4 points to check when buying balls.
1. Outdoor or Indoor?
The golden rule is to match the ball to your playing environment. If you mostly play outdoors, choose outdoor balls; if indoor gyms are your main venue, go with indoor balls. If you "play both," I recommend keeping mainly outdoor balls in stock (outdoor balls can be used indoors, but indoor balls drift a lot in the wind, so they're not suited to outdoor play).
2. Is It USAP Approved?
A must if you're playing in matches, tournaments, or official practice sessions. Check the model on the official list.
3. Color Visibility
Outdoors, yellow or orange stands out against the background. Indoors, white or fluorescent colors are easier to see under the lights. Be careful with dark-colored balls on cloudy days, as they're easy to lose sight of.
4. Buy by the Dozen
Pickleball balls are consumables. Buying packs of 6 or 12 is better value than buying them one at a time. For intermediate players and above, keeping about two dozen in stock is standard.
Ball Lifespan and When to Replace
Pickleball balls have a hollow plastic structure, so they gradually wear out with use.
Estimated Lifespan
| Frequency of use | Estimated lifespan |
|---|---|
| Light practice (1–2 hours/week) | 1–2 months |
| Moderate (3–4 hours/week) | 2–4 weeks |
| Competitive (5+ hours/week) | 1–2 weeks |
Signs It's Time to Replace
- Cracked or split: Replace immediately. A cracked ball flies unpredictably.
- No longer perfectly round: An oval-shaped ball bounces unexpectedly.
- Hole edges are worn and jagged: The way the ball grips the paddle changes, throwing off your feel for spin.
- The sound has clearly changed: When the "pop" starts to sound more like a dull "thud," it's done.
💡 Coach Yoshi's Tip
You often don't notice the moment a ball cracks. If you feel like "hmm, it's not carrying" during a rally, check the ball's shape. If you keep playing with a cracked ball, it will even throw off your sense of your own form. It's best to switch to a new ball the moment you think "something's off."
How They Differ from Tennis Balls and Table Tennis Balls
I'll also answer the question, "How are pickleball balls different from tennis balls, badminton shuttlecocks, and table tennis balls?"
| Sport | Diameter | Weight | Surface | Bounce |
|---|---|---|---|---|
| Pickleball (outdoor) | Approx. 74mm | Approx. 26g | 40 holes, hard plastic | Bounces but slows down quickly |
| Tennis ball | Approx. 67mm | Approx. 58g | Felt | Bounces well, takes spin well |
| Table tennis ball | Approx. 40mm | Approx. 2.7g | Smooth plastic | Light, takes spin well |
| Badminton shuttlecock | — | Approx. 5g | Feathers or plastic | Slows down sharply in the wind |
Pickleball balls are less than half the weight of tennis balls (approx. 26g vs. approx. 58g), and they also have less rebound than tennis balls. That's why, if you swing all the way through like you would in tennis, the ball may not carry as far as you expect and floats up, or its trajectory becomes unstable. Learning to control a "light ball with less rebound" is the first step in pickleball.
Summary
- Pickleball balls come in two types: outdoor (around 40 holes, harder) and indoor (around 26 holes, softer).
- Outdoor balls have more, smaller holes and are harder, designed to resist wind and reward drives.
- Indoor balls have fewer, larger holes and are softer, rewarding delicate touch.
- USAP-approved balls are a must for matches and official practice sessions. You can check them on the official list.
- Representative models: outdoor—Franklin X-40 / Onix Fuse Outdoor / Engage Neon Tour Ball 2.0; indoor—Onix Fuse Indoor / Gamma Photon.
- Balls are consumables. Intermediate players and above should keep about two dozen in stock and replace them as soon as they feel deformed or worn.
- Compared to tennis balls, pickleball balls are lighter and larger, so hitting with a tennis mindset often sends the ball long.
If you want to enjoy pickleball for a long time, choosing the right ball is just as important as choosing a paddle. Choose the approved ball that best fits your playing environment and goals.
If you're wondering "Where can I buy approved balls?" or "I'm a beginner—what should I get first?", feel free to send a message to Pickleball Lab's official LINE account. Tell me where and how often you play, and I (Coach Yoshi) will help you choose the right balls.
