Padel looks simple from the outside, but the ball is one of the most tightly regulated pieces of equipment in the sport. Every ball used in an official competition has to clear a defined technical standard, and the body that sets and enforces that standard is the International Padel Federation (FIP).
As of September 2026, Mint Sport's Cannonballz™ Premium Tournament Padel Balls are FIP approved. Here's what that approval actually involves, why it matters, and what it does and doesn't tell you about a ball.
What is the FIP, and why does it approve balls?
The International Padel Federation is the world governing body of padel. It began its ball approval program on April 1, 2017, with a simple goal: standardize the balls made by manufacturers around the world so that a ball behaves the same way whether you're playing in Madrid, Dubai or Miami.
The rule that follows from that is straightforward. Only FIP-approved balls may be used in FIP tournaments and in competitions on the official calendar, including FIP Championships, Premier Padel, the CUPRA FIP Tour and FIP Promises, plus other competitions the federation recognizes worldwide. If a ball isn't certified, it can't be on court at those events, however good it feels in the tube.
What a padel ball has to meet
FIP's rules define the standard ball by a handful of measurable properties. These are the numbers that matter:
| Property | FIP requirement (standard ball) |
|---|---|
| Weight | 56.0 to 59.4 grams |
| Diameter | 6.35 to 6.77 cm |
| Rebound | 135 to 145 cm when dropped from 2.54 m onto a hard surface |
| Forward deformation | 0.56 to 0.74 cm |
| Return deformation | 0.80 to 1.08 cm |
| Internal pressure | 4.6 to 5.2 kg per 2.54 cm² (as written in the rulebook) |
| Color | Any, as long as it contrasts clearly with the court surface |
Two details are worth understanding.
Rebound is the headline number. A ball dropped from 2.54 meters (100 inches) has to come back up between 135 and 145 cm. That narrow window is what gives padel its characteristic feel: lively enough to rally off the glass, but not so lively that points turn into wild bounces.
Deformation measures how the ball compresses under load and recovers. FIP also requires that deformation readings taken along three perpendicular axes don't differ by more than 0.08 cm. In plain terms, the ball has to be round and uniform in how it squashes, not lopsided.
The rulebook also describes the ball's construction: a hollow rubber core covered in a felt made from a combination of textile fibers such as cotton, wool and nylon, with a mostly smooth surface. Cannonballz™ padel balls pair natural rubber with high-flex felt that includes a 57% wool blend, and they come pressurized and ready to play from the tube.
How a ball earns approval
Approval isn't a paperwork exercise. A manufacturer has to submit real product to an FIP-accredited laboratory, and the process is built to catch inconsistency:
- A large sample is submitted. The manufacturer provides a box of 24 cans, which is 72 balls.
- The lab picks the balls, not the manufacturer. The laboratory randomly selects 24 balls from that sample.
- The balls are conditioned. They rest in a controlled atmosphere for at least 24 hours, with temperature, humidity and atmospheric pressure recorded in the test report.
- Each ball is measured individually. Every ball is marked and tracked, then tested for weight, size, rebound and deformation.
- Durability is tested too. The balls go through a test that simulates nine games of play, then are measured again. After that simulated wear, a ball can't have lost more than 0.4 grams, 4.0 cm of rebound, 0.08 cm of forward deformation or 0.10 cm of return deformation.
- FIP reviews the report. The lab sends results to the federation, and FIP decides whether the ball meets the rules before approval is granted.
Only three laboratories are accredited for this work: Labosport in Le Mans, France; RINA in Rome, Italy; and the Instituto de Biomecánica de Valencia (IBV) in Spain.
The durability step is the part many players overlook. A ball that bounces perfectly out of the can but goes flat after a few games would pass a basic check and still be a poor tournament ball. FIP's standard requires it to hold its character through simulated play.
What FIP approval does and doesn't mean
It helps to be precise here, because "approved" gets used loosely.
It does mean the ball met FIP's technical specification for padel, as verified by an accredited lab, and that the manufacturer can use the FIP Approved logo on packaging, websites and marketing for that model.
It doesn't mean approval is permanent. Certification runs on a two-year cycle and must be renewed. FIP also reserves the right to withdraw approval if the balls on the market stop matching the sample that was tested, or if they otherwise fall short of a reasonable quality standard. Approval is something a brand keeps earning.
It doesn't carry over to other sports or governing bodies. FIP states that its approval is based on the Rules of Padel and implies no other form of approval. That's a useful point of clarity for Mint Sport customers: Cannonballz™ padel balls are approved by FIP for padel, while the Cannonballz™ pickleball balls are a separate product line approved to USAPA standards for pickleball. Two sports, two rulebooks, two different balls.
Where Cannonballz™ padel balls fit
The Cannonballz™ Premium Tournament Padel Balls are built for competitive play and sold in tubes of four. Key points for players:
- FIP approved. Approved for tournament and competitive play, with approval confirmed on September 28, 2026.
- Natural rubber and high-flex felt with a 57% wool blend.
- Pressurized and ready to play straight out of the tube, with no pumping or warm-up needed.
- High-visibility felt that stays easy to track in different lighting.
- Stable flight and a predictable bounce that suit tournament players but stay easy to control for newer players.
If you run a club, league or tournament, an approved ball removes a common headache. Organizers at FIP-level events have to announce the ball brand and model in advance, and having an approved model on the list keeps you aligned with the rules those events follow. Even if you never play a sanctioned match, a ball built to the same standard as the pros' gives you a consistent baseline for practice.
How long should padel balls last?
The nine-game durability test is a lab simulation, not a promise about your own court time, since real wear depends on surface, temperature, how hard you hit and how often you play. As a practical guide, recreational players typically get around three to five games from a tube, while competitive players often change balls after just one or two games.
Whatever your level, replace the balls when they go soft, lose their pop or stop bouncing consistently. A tired ball is the quickest way to make good technique feel off.
Quick answers
Are Cannonballz™ padel balls FIP approved?
Yes. Cannonballz™ Premium Tournament Padel Balls were approved by the International Padel Federation on September 28, 2026.
What does "FIP approved" mean for a padel ball?
It means an accredited laboratory tested the ball and it meets FIP's standards for weight, size, rebound, deformation, pressure and durability, and that FIP has granted approval for use in its tournaments.
Can I use FIP-approved balls for recreational play?
Absolutely. You don't need an approved ball for casual games, but using one gives you the same consistent flight and bounce that tournament players rely on.
Are padel balls the same as tennis balls?
No. They look similar, but padel balls are slightly smaller and have a lower bounce than tennis balls, and they're tested against padel-specific specifications.
Are Cannonballz™ pickleball balls also FIP approved?
No, and they don't need to be. FIP governs padel. Cannonballz™ pickleball balls are USAPA approved for pickleball.
