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 common questions we often hear from our customers. In fact, pickleball balls come in two distinct types, and choosing the wrong ball can significantly impact play to the point where it feels completely off.
As Yoshi Coach, who has playtested over 100 paddles, I will thoroughly explain everything you need to know about choosing pickleball balls, from the differences between outdoor and indoor balls to how to identify USAP-approved balls and select 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 smaller than a tennis ball) and weigh between 22-26g (about 1/3 the weight of a tennis ball). The primary 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 distinguishing outdoor from indoor balls.
| Item | Outdoor | Indoor |
|---|---|---|
| Number of Holes | 40 | 26 |
| Weight | Slightly heavier (approx. 26g) | Slightly lighter (approx. 22-24g) |
| Hardness | Harder | Slightly softer |
| Primary Playing Environment | Outdoor courts (with wind) | Indoor courts (no wind) |
| Color | Neon green, yellow, orange are common | White and yellow are mixed |
💡 Yoshi Coach's Tip
Some people start with 100-yen store plastic balls thinking "any will do," but honestly, 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. Your improvement speed will visibly change.
Characteristics of Outdoor Balls
Outdoor balls are designed to minimize the impact of wind.
Design Features
- More holes (40): Distribute air resistance, making the trajectory less likely to be significantly affected by wind.
- Heavier weight (approx. 26g): Less likely to be pushed by wind, falls stably on the court.
- Harder: Consistent bounce on hard outdoor courts. Also more durable.
Playing Feel
Outdoor balls offer a sensation of the ball firmly gripping the paddle face. When you hit a drive or a third-shot drive, you feel a satisfying "thwack" as the power is transferred. The big advantage is being able to aim for your desired spot even on windy days.
When to Use
- Outdoor park courts, tennis court conversions
- Tournament qualifiers and main draws (often outdoors)
- All play on windy days
Representative Models
- Franklin X-40: USAP approved, official ball of the PPA Tour. The standard for outdoor professional tournaments.
- 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 classic model with a long history. Also used in the US Open / USAP National Championships.
- Engage Neon Tour Ball 2.0 (Available in our store): USAP approved, 40-hole. Features enhanced visibility with neon green and a newly developed polymer material for stable flight and durability in both hot and cold conditions. Also characterized by low vibration and quiet design. Available from our store, an authorized Engage Japan dealer → View Product Page
Characteristics of Indoor Balls
Indoor balls are designed for delicate control in environments without wind.
Design Features
- Fewer holes (26): Less air resistance, flies straighter.
- Lighter weight (approx. 22-24g): Allows for finer touch.
- Slightly softer: Consistent bounce on indoor gym floors and wooden courts.
Playing Feel
Indoor balls have a sensation of the ball "floating" softly. Compared to outdoor balls, they are milder, making it easier to achieve precision with dinks and drop shots. However, when used outdoors, they are significantly affected by wind and become unplayable.
When to Use
- Indoor gyms, sports centers
- Home garages, community centers
- Outdoor courts on non-windy days (can be used as an alternative to outdoor balls)
Representative Models
- Onix Fuse Indoor: USAP approved, standard ball frequently used in indoor tournaments.
- Jugs Indoor: Indoor-specific, 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 subject to USA Pickleball (USAP) approval standards. If you are playing in a match or an official practice session, always choose an approved ball.
Checkpoints for Approved Balls
- "USA Pickleball Approved" marking on the ball itself or its packaging.
- The model number can be found on the official list (USAP Approved Ball List).
- Diameter, weight, coefficient of restitution, and hardness are within official specifications.
Risks of Using Non-Approved Balls
- Unstable flight: Unexpected behavior due to non-standard hole placement or weight balance.
- Low durability: May crack after 1-2 matches.
- Cannot be used in matches: Not permitted in tournaments that specify approved balls.
💡 Yoshi Coach's Tip
In Japan, some people buy cheap balls from 100-yen stores or Amazon "just because they're cheap." While they might be okay for light practice, if you're at the stage where you want to improve your spin and drop shot accuracy, you must switch to approved balls. Even if you make the same movements, the ball's behavior will be different, preventing you from acquiring the correct technique.
Ball Purchase Checklist
Here are 4 points to check when buying balls.
1. Outdoor or Indoor?
It's crucial to match the ball to your playing environment. If you play outdoors frequently, choose outdoor balls; if indoor gyms are your primary venue, go for indoor balls. If you "play both," I recommend stocking up mainly on outdoor balls (outdoor balls can be used indoors, but indoor balls are not suitable for outdoor play due to significant wind drift).
2. USAP Approved?
Essential if you're participating in matches, tournaments, or official practice sessions. Check the model number on the official list.
3. Color Visibility
For outdoor play, yellow or orange are easier to distinguish against the background. Indoors, white or fluorescent colors are easier to see under artificial lighting. Be careful with black balls on cloudy days, as they can be hard to spot.
4. Purchase by the Dozen
Pickleball balls are consumables. It's more cost-effective to buy them in packs of 6 or 12 than individually. Intermediate players and above typically stock about two dozen balls.
Ball Lifespan and Replacement Timing
Pickleball balls are hollow plastic structures, so they gradually deteriorate with use.
Estimated Lifespan
| Usage Frequency | 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 for Replacement
- Cracked or split: Replace immediately. A cracked ball will have unpredictable flight.
- Loss of spherical shape: An oval ball will have unexpected bounces.
- Hole edges are worn and jagged: Affects paddle grip, causing spin sensation to deviate.
- Noticeable change in sound: If it changes from a "pop" to a "thud," it's reached its lifespan.
💡 Yoshi Coach's Tip
You often don't notice the moment a ball cracks. If you feel like it's not flying right during a rally, check the ball's shape. Continuing to play with a cracked ball will mess up your own swing mechanics. It's best to switch to a new ball the moment you think "something's off."
Differences from Tennis Balls and Table Tennis Balls
I'll also address the question, "How are pickleball balls different compared to 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, good spin |
| Table Tennis Ball | Approx. 40mm | Approx. 2.7g | Smooth plastic | Light, good spin |
| Badminton Shuttlecock | — | Approx. 5g | Feathers or plastic | Significantly slows down in 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. Therefore, if you swing with the same feeling as tennis, the ball might not fly as far as expected or its trajectory might be unstable. Controlling a "light ball with less rebound" is the first step in pickleball.
Summary
- Pickleball balls come in two types: outdoor (40 holes, heavier) and indoor (26 holes, lighter).
- Outdoor balls have more holes, are heavier, and harder, designed to be wind-resistant, enhancing drives.
- Indoor balls have fewer holes, are lighter, and softer, enabling delicate touch.
- USAP-approved balls are mandatory for matches and official practice sessions. Check the official list for verification.
- Representative models: Outdoor include Franklin X-40 / Onix Fuse Outdoor / Engage Neon Tour Ball 2.0 (available in our store); Indoor include Onix Fuse Indoor / Gamma Photon.
- Balls are consumables. Intermediate players and above should stock about two dozen and replace them immediately if they feel deformed or worn.
- Compared to tennis balls, pickleball balls are lighter and larger, so hitting them with a tennis mindset often results in over-hitting.
If you want to enjoy pickleball for a long time, choosing the right ball is just as important as choosing a paddle. Select the optimal approved ball based on your playing environment and goals.
