Open any padel racket spec sheet and you will find a thickness figure sitting quietly next to the weight and the balance. On almost every performance racket on the market, that number reads the same: 38 mm. Players still agonise over it, convinced that a fraction of a millimetre is the difference between a cannon and a marshmallow. It is not. Padel racket thickness is the most regulated, most identical, and frankly least useful number on the whole page, and once you understand why, you stop shopping by it and start shopping by the specs that actually move your game.
TL;DR
- 38 mm is a legal ceiling, not a feature: the FIP caps padel racket thickness at 38 mm, so brands compete up to the line, not past it.
- Almost every adult racket is 38 mm: the moulds are standardised, so the thickness column tells you very little between two performance palas.
- 36 mm exists, and it usually means "lighter": thinner frames are mostly junior and entry models, where the real change is weight, not the 2 mm.
- Power and forgiveness come from inside: core density (EVA), balance and shape decide how the racket plays, not the outer profile.
- Read four specs, skip thickness: weight, balance, core hardness and shape tell you everything the thickness number pretends to.
The one racket number nobody is allowed to change
Padel is a tightly regulated sport at the equipment level. The International Padel Federation (FIP) fixes the exact envelope a legal racket has to live inside, and thickness is part of that envelope.
Under the current FIP Rules of Padel, a racket cannot exceed 45.5 cm in total length (head plus handle), 26 cm in width, and 38 mm in thickness. During an official dimensional check, inspectors allow a small tolerance of about 2.5 percent, so a frame measuring a hair over 38 mm will still pass, but nothing is designed to sit meaningfully above the line. You can read the full envelope in the FIP Rules of Padel.
Here is the important consequence. When a legal maximum exists and it happens to be the most performance-friendly value, everyone builds right up to it. That is why "38 mm" is printed on nearly every pala you will ever hold. It is not a bragging point. It is the ceiling of the room, and the whole industry is standing on tiptoe touching it.
Why almost every padel racket is exactly 38 mm
If thickness were a genuine performance dial, you would expect a spread: 34 mm, 36 mm, 38 mm, each tuned for a different player. You do not see that spread, and the reason is manufacturing, not physics.
Padel rackets are built by curing carbon or fibreglass skins around an EVA foam core inside a mould. Those moulds are expensive tooling, and the industry standardised on the 38 mm cavity years ago because it is the legal maximum and it leaves room for a generous core. Retooling a factory to produce a 35 mm or 37 mm frame at scale is a large cost for a change most players would never feel. So brands simply do not do it. The thickness is inherited from the mould, and the mould is 38 mm.
There is one honest exception: 36 mm frames. You find them mostly in junior rackets and some beginner and women's models. But notice what really travels with that thinner profile. Those rackets are also lighter, usually in the 320 to 355 gram range instead of 360 to 375. The player feels the lower weight and the smaller swing, not the two millimetres of profile. Calling a 36 mm racket "thinner" is technically true and practically misleading. It is a lighter racket that happens to be thinner.
The wrong-X trap: what thickness actually changes
This is the trap. A shopper reads "38 mm" and assumes a thicker frame stores more energy and hits harder, the way a thicker diving board launches you higher. Padel does not work like that, because the 38 mm is not a solid slab. It is two thin structural skins with a block of foam between them, and that foam is where the racket's personality lives.
Independent teardowns and playtests keep landing on the same conclusion: how a racket feels comes from the density of the core and the balance point, not the outer thickness. A harder EVA core stores and returns energy fast, so it feels powerful on a clean central hit but punishes off-centre contact with a smaller sweet spot. A softer core spreads contact over more surface, enlarging the sweet spot and adding comfort at the cost of raw punch. That trade lives inside the 38 mm, not in the millimetres themselves.
So the thickness number is not lying to you. It is just answering a question you did not need to ask. The useful questions are underneath it.
| The spec you read | What you think it controls | What actually controls it |
|---|---|---|
| Thickness (38 mm) | Power and pop | Core density (EVA hardness) and shape |
| Thickness (38 mm) | Sweet spot size | Core hardness, shape and balance |
| Thickness (36 vs 38 mm) | Beginner vs advanced feel | Weight and swingweight (which move together with it) |
| Frame thickness | Comfort on the arm | Core softness, balance and grip size |
36 mm vs 38 mm: the real difference is weight, not the millimetres
Picture the two profiles side by side. The 38 mm frame gives the designer a slightly larger foam volume to work with, which can support a broad, stable sweet spot. The 36 mm frame is a touch shallower and, on the models where it appears, noticeably lighter and easier to swing. The temptation is to credit the millimetres. The honest read is that you are feeling the weight and the balance the brand paired with that profile.
At Ace One Padel, we have broken down every dimension of a pala for this blog, and thickness is the one where the marketing noise most outruns the physics. If you want a softer, more forgiving 38 mm racket, our TŸR line pairs a 3K carbon face with a soft EVA core for control and comfort. If you want the explosive end of the same 38 mm envelope, the Cøre 12K stiffens everything up for power. Same legal thickness, completely different rackets, because the difference was never the millimetres.
How to read a padel racket like a pro (skip thickness, read these four)
Next time you compare two rackets, cover the thickness column with your thumb and read these instead. This is the order that actually predicts how a pala will play in your hand.
- Weight: the first thing your arm feels. Lighter frames (around 355 g) are easier to swing and gentler on the elbow; heavier ones (365 to 375 g) add plough-through on volleys and smashes.
- Balance: where the mass sits. Head-heavy rewards attackers, head-light rewards fast hands at the net. See our padel racket balance guide for how to feel it in a shop.
- Core hardness: soft versus hard EVA is the single biggest driver of power, comfort and sweet spot size. Our racket core explainer covers the trade in full.
- Shape: round, teardrop or diamond moves the sweet spot up or down the face and shifts the whole power-control balance. That, plus core density, is what really sets your sweet spot.
Get those four right and the racket will feel like an extension of your arm. The thickness will read 38 mm, and you will finally know why that does not matter. When you are ready to choose, browse the full Ace One Padel rackets collection and match the core and balance to your game, not the number that is the same on every box.
The Ace One Padel Verdict
Thickness is the spec that looks like a performance lever and behaves like a legal formality. The FIP caps it at 38 mm, standardised moulds pin nearly every adult racket to that ceiling, and the 36 mm frames you do find are really telling you "lighter," not "thinner." The genuine dials, core density, balance, weight and shape, all live inside that fixed profile. So stop comparing thickness numbers that are already identical, learn to read the four specs that change, and choose a racket by how it is built, not by a millimetre reading that regulation already decided for you.
Frequently asked questions
How thick is a padel racket?
The maximum legal thickness is 38 mm under FIP rules, with a small 2.5 percent tolerance at official inspection. Nearly every adult performance racket is built to that 38 mm ceiling. Some junior and entry models are 36 mm, and those are usually lighter as well.
Does a thicker padel racket give more power?
No. The 38 mm profile is two thin skins around an EVA core, and power comes from the core's density and the racket's balance, not the outer thickness. A hard core feels more powerful; a soft core feels more forgiving, both at the same 38 mm.
Are all padel rackets 38 mm?
Almost. 38 mm is the FIP maximum and the standard mould size, so the vast majority of adult rackets sit there. The main exceptions are 36 mm junior, beginner and some women's models, where the thinner profile comes with a lighter overall frame.
Is a 36 mm or 38 mm padel racket better?
Neither is better on thickness alone. Choose by weight, balance, core hardness and shape. A 36 mm racket suits players who want a lighter, easier swing; a 38 mm racket is the standard performance envelope and can be tuned soft or stiff depending on its core.
