What Strings Do Pro Tennis Players Actually Use in 2026?

There's a question every club player asks at some point: what strings do the pros actually use? It's a fair question. If someone like Novak Djokovic is winning Slams with a particular setup, it's natural to wonder whether the same string sitting in your frame might unlock something in your own game. The short answer is that the string alone won't do that — but the long answer is far more interesting, and a lot more useful.

Because here's the thing: understanding why pros choose what they choose tells you something genuinely valuable. It's not about copying the setup exactly. It's about taking the principles behind those choices and applying them at your level. That's where the real insight is.

The Most-Used Strings on the ATP and WTA Tour in 2026

Let's start with the numbers. Roughly 28 of the top 50 ATP players are using Luxilon strings, and within that group, Luxilon Alu Power is the dominant model by a wide margin. It's the most played string on tour, full stop. That's not marketing — it's been the case for years and 2026 is no different.

Beyond Alu Power, here's a honest snapshot of what's in the frames of the world's best:

• Jannik Sinner and Alexander Zverev — Head Hawk Touch. A co-poly that sits in a different lane to Alu Power: more feel, slightly more spin-friendly, a touch livelier off the string bed.
• Rafael Nadal — Babolat RPM Blast has been his setup for most of his career. His successor at the top of the spin game, Carlos Alcaraz, uses Babolat RPM Team — same family, slightly different character.
• Frances Tiafoe and Nick Kyrgios — Yonex Poly Tour Pro. Two very different players, but both drawn to a string that offers a balance of pop and control, without being as muted as Alu Power.
• Naomi Osaka — also a Yonex Poly Tour Pro player.
• Daniil Medvedev — Tecnifibre Black Code. A 4-sided hexagonal co-poly with serious spin potential and a crispness that suits his flat, precise baseline game.
• Novak Djokovic — Wilson Natural Gut mains / Luxilon Alu Power crosses. A full hybrid setup. More on that in a moment.
• Roger Federer (throughout his career) — Natural gut mains / Luxilon Alu Power Rough crosses. Same hybrid philosophy as Djokovic, different texture in the Alu Power cross.

What do you notice? Almost every name on that list is playing polyester, or a combination that includes polyester. That's not a coincidence.

Why Every Top Pro Uses Poly — and What That Actually Means

Not a single player in the top 100 is playing full multifilament. That should tell you something about the demands of elite tennis — and it should also tell you something about the limits of drawing direct comparisons between tour setups and your own.

Polyester strings give pros what they need: control at high swing speeds, predictable ball flight, and the ability to swing freely without worrying that the ball will fly long. When you're generating racquet head speed north of 130 km/h, a high-powered multifilament is a liability. The poly keeps the ball in the court.

The physics here is worth understanding. Polyester is a stiffer material than multifilament or natural gut. At contact, it deforms less, returns energy more efficiently, and gives the player a crisper, more connected response. The stiffness also means less trampoline effect — less power added by the strings themselves — which gives pros confidence to swing out fully without adding unintended pace.

The spin picture is more nuanced. Poly's low string-to-string friction allows the main strings to slide across the crosses at contact, then snap back as the ball leaves. That snapback is what generates topspin. It's not the hardness of the string that creates spin — it's the snapback mechanism. According to Tennis Warehouse University's testing, the coefficient of friction between strings is one of the most important variables in spin generation. Poly does this well. Multifilaments don't, because their textured surfaces create too much friction between strings.

So far, so logical. But here's where most club players go wrong.

The Part No One Tells You: Why the Pro Setup Doesn't Work for Most of Us

The same property that makes stiff poly work at 130+ km/h — that firmness, that resistance to deformation — is exactly what makes it uncomfortable and ineffective for most club players.

At 80 or 90 km/h of swing speed, you don't generate enough impact force to make the string bed compress and respond properly. You're essentially hitting a stiff surface without the swing speed to unlock what it's designed to do. The result? A harsh, boardy feel. Reduced power from the strings (which normally helps club players clear the net). And real arm load — that jarring vibration transfers straight up the kinetic chain.

The touring pro's arm is also built for this. Years of training, elite technique, and full swings from the shoulder generate the speed and consistency that make stiff poly perform. When you're tentative with a stiff string — and many club players are, because the string punishes you if you're not swinging fully — you don't get the spin or control the string is capable of. You just get the discomfort.

There's a reason so many club players blame their strings when the real issue is that they're playing a pro setup with a club-level swing.

The Tension Surprise: Pros String Lower Than You Think

Here's something that genuinely surprises most people: Djokovic reportedly strings his hybrid around 48–52 lbs. Not 60. Not 65. Around 50.

That flies in the face of the widespread belief that pros string tight for control. The reality is the opposite. Lower tension means more pocketing — the ball sinks deeper into the string bed at contact, which increases dwell time, adds feel, and actually improves spin production because the strings have more room to move and snap back. The control comes from the player's technique and swing, not from a cranked-up tension.

This matters for you directly. If you're stringing your poly at 58 or 60 lbs because you think that's what serious players do, you're likely playing a string that's far stiffer and more arm-unfriendly than it needs to be, with less of the feel and response that makes it worth playing in the first place. Most poly strings come alive at lower tensions — usually in the 48–54 lb range depending on the frame — and that's where they reward you.

Drop the tension. Seriously. Try 4–6 lbs lower than wherever you are now and notice what changes.

The Hybrid Reality: The Best Players Aren't Playing Full Poly

Look again at the elite end of the list. Djokovic — hybrid. Federer's entire career — hybrid. These are arguably the two greatest players in history, and neither committed to full poly.

A gut/poly hybrid is genuinely the best of both worlds if you can justify the cost and the restringing frequency. Natural gut mains give you an extraordinary feel — what Rackets & Runners calls "almost magical", and it's not an exaggeration. The gut's elasticity provides comfort, power, and that unmistakable connected response that no synthetic can fully replicate. The poly crosses add control, reduce the total cost compared to full gut, and increase durability.

The catch is cost. Gut is expensive, and stringing frequently is part of the deal with any hybrid. If you're restringing every six months, the playability equation changes — the gut side will have lost its magic long before the poly side wears out. Hybrids make sense when you're restringing at least every 4–6 weeks, or more often in summer.

That said, you don't need full gut to borrow this logic. Many players run a softer multifilament in the mains with a poly cross and get a meaningfully more comfortable and lively setup than full poly, at a fraction of the cost.

What Club Players Can Actually Take From All This

Here's where this gets genuinely useful. You don't need to copy a pro's string. But you can absolutely borrow the principles behind it.

Luxilon Alu Power — The Benchmark Worth Trying

There's a reason Alu Power is everywhere on tour. It's the reference point that everything else in the round poly category is measured against. The feel is distinctive — muted, connected, and what Tennisnerd describes as "just special" in terms of ball pocketing. It communicates precisely where you are in the string bed. Off-centre hits don't lie to you.

For club players who swing with confidence and take the ball early, Alu Power is worth experiencing at least once. String it at 50–52 lbs, give it a session to bed in, and then assess. It won't give you everything for free — it rewards players who swing through the ball rather than guide it — but if your game clicks with it, you'll understand why it's been the dominant force on tour for two decades.

Browse Luxilon strings at The Tennis Store, including Alu Power in standard and Rough variants.

Head Hawk Touch — More Accessible Than You'd Expect

Sinner and Zverev don't play the hardest string in the world. Hawk Touch is a co-poly with a softer feel than standard Alu Power — it's a little livelier, a little more forgiving, and more accessible for players who want a touch of poly control without the harshest end of the spectrum. If you've tried full poly and found it too firm, Hawk Touch is a logical next step before abandoning the category entirely.

Head Hawk Touch is available at The Tennis Store — worth trying if you want to understand what Sinner's playing with.

Yonex Poly Tour Pro — The Nick Kyrgios Option

Kyrgios is the most relevant tour player for Australian fans who want to connect their string choice to someone they actually watch. He plays Poly Tour Pro, and it suits his aggressive, flat-hitting, big-serving game well. It's a round co-poly with good tension maintenance and a livelier response than Alu Power — a bit more pop, a bit less of the muted, connected feel that defines Alu Power.

For club players who like pace and hit fairly flat, it's a very solid option. It sits in the middle of the poly spectrum — not too stiff, not too soft — which makes it genuinely accessible.

Yonex Poly Tour Pro is stocked at The Tennis Store across gauges.

The Tension Rule That Applies to Everyone

Whatever string you try, don't copy the tension you see quoted for tour players without adjusting down. Pros have string technicians who fine-tune tension to their exact swing, they restring multiple times per tournament, and their dynamic tension (the tension after the string has settled) is calibrated to within a narrow window. Your stringer is probably working from a number you picked six years ago and never revisited.

If you're playing poly: try 48–54 lbs. If you've been stringing at 60, drop 8 lbs on your next job and play a set. The string will feel completely different — more responsive, more lively, with better spin production. That's not placebo. That's physics.

Frequently Asked Questions About Pro Tennis Strings

What strings do most professional tennis players use?

The majority of professional tennis players use polyester strings or a hybrid setup combining natural gut mains with polyester crosses. Luxilon Alu Power is the most-used string on the ATP Tour, with approximately 28 of the top 50 ATP players using Luxilon products overall. Other popular tour strings include Babolat RPM Blast, Head Hawk Touch, Yonex Poly Tour Pro, and Tecnifibre Black Code.

Does Novak Djokovic use natural gut strings?

Yes, but not exclusively. Djokovic plays a hybrid setup with Wilson Natural Gut in the mains and Luxilon Alu Power in the crosses. This gives him the feel and power of natural gut where it matters most (the main strings make the most contact with the ball) combined with the control and durability of Alu Power in the crosses. Roger Federer used the same hybrid philosophy throughout his career.

What tension do pro tennis players string at?

Lower than most people expect. Djokovic reportedly strings his hybrid around 48–52 lbs. Many tour players use tensions in the low-to-mid 50s, not the 60+ lbs that recreational players often assume. Lower tension provides better feel, more ball pocketing, and improved spin production — the control comes from technique and swing speed, not from a tighter string bed.

Should I use the same string as my favourite pro player?

You can try it, but manage your expectations. Pro players swing at 130+ km/h, restring after every match or every few matches, and have elite technique that makes stiff polyester work. At club level, the same string may feel boardy, reduce your power, and place unnecessary load on your arm. A better approach is to understand the principles behind their choice — control, spin potential, tension — and find a string in that category that suits your swing speed.

What is Luxilon Alu Power and why do pros use it?

Luxilon Alu Power is a round aluminium-infused co-polyester string that has been the most popular string on the ATP Tour for over a decade. Pros use it for its distinctive muted, connected feel, its exceptional control at high swing speeds, and its predictable ball flight. It doesn't add power — it removes it — which is exactly what pros want when they're swinging at maximum speed. For club players, it's the benchmark round poly worth experiencing at least once, ideally strung at 50–52 lbs.

Do pro players use hybrid string setups?

Many of the very best do. Djokovic and Federer both used or use gut/poly hybrid setups — natural gut mains for feel and comfort, Alu Power crosses for control. Hybrid setups are common among elite players because they offer a genuine best-of-both-worlds result: the feel of gut where the string contacts the ball most, and the control and durability of poly in the cross strings. It's more expensive and requires frequent restringing, but the playability difference over full poly is real.

Luxilon Alu Power, Head Hawk Touch, and Yonex Poly Tour Pro are all available now at The Tennis Store, with fast shipping across Australia — so you can try the tour-proven strings on your own terms, at the right tension for your game.
