The Best Tennis Strings

String changes how a racquet plays more than most players believe, and costs a tenth of a new frame. Here is what each type actually does, and the six worth buying.

The best tennis string for most club players is Solinco Hyper-G Soft 17 — a shaped polyester that delivers most of an RPM Blast's spin and control for roughly half the money, which matters because polyester needs replacing often. If your arm is the constraint, buy a multifilament instead: HEAD Velocity MLT on a budget, Wilson NXT if you restring frequently enough to justify a reel.

Why string is the upgrade nobody makes

Club players obsess over frames and ignore strings, which is backwards. The same racquet strung with a stiff polyester and with a soft multifilament plays like two different racquets: one gives you control at full swing speed and a tiring arm, the other gives you free depth and comfort. Nothing you can do to a frame changes it that much.

It is also where the money is. A restring costs a fraction of a racquet, and a dead string bed in a good frame plays worse than a fresh one in a mediocre frame. If you have not restrung this year and you play weekly, that is the upgrade — not a new racquet. See how often to restring.

The three families

Polyester (co-polyester, “poly”).Stiff, low-powered, high-control — see strings for controlfor the ranking. The mains slide and snap back, which generates spin. Everything the professional game uses. The cost is comfort: poly is hard on arms, and it goes dead well before it breaks. Examples here: Hyper-G, ALU Power, RPM Blast, Lynx Tour.

Multifilament.Thousands of fibres bundled in polyurethane, engineered to imitate natural gut. Soft, elastic, powerful, comfortable. The cost is control at high swing speeds and durability — it frays and breaks far faster under heavy spin. Examples here: NXT, Velocity MLT, Sensation.

Natural gut.Actual processed cow intestine, and still the best-playing string in tennis. Unmatched elasticity, the best tension maintenance of any string, and the most arm-friendly option that exists. The cost is money and water — it is several times the price of a quality poly and it is damaged by moisture.

The hybrid most club players should actually use

You do not have to choose. A hybrid puts polyester in the mains, where the snapback that creates spin happens, and a multifilament or gut in the crosses, where comfort lives. You get most of the control and spin of a full poly bed with meaningfully less shock.

For a 3.5–4.5 player this is very often the right answer and almost nobody is told about it. Ask your stringer for poly mains and a multifilament cross; the cost difference is negligible.

Pros

  • Square profile for spin, in the Soft version that takes a real edge off the harshness of standard Hyper-G
  • Among the cheapest quality polys sold, which matters because poly needs replacing often
  • Holds tension noticeably better than most budget polyesters

Cons

  • 'Soft' is relative — it is still a polyester and still stiffer than any multifilament
  • The bright green dye transfers onto light-coloured frames

Don't buy this if…

…you are stringing a stiff frame and have elbow history. Soft poly is not soft enough for that combination.

Pros

  • The reference polyester — if you have ever read a string review, it was compared to this
  • Exceptional control: it holds a flat drive in the court at full swing speed
  • Crisp, precise feedback that tells you exactly where you made contact

Cons

  • Stiff. A full ALU bed in a stiff frame is the classic tennis-elbow recipe
  • Loses tension faster than its reputation suggests — plan on restringing before it feels dead

Don't buy this if…

…you are below 4.0 or have any arm trouble. Buy a multifilament; you will hit a better ball and keep your elbow.

Pros

  • Thousands of fibres bundled in polyurethane give it the elastic, ball-pocketing feel of natural gut

  • A 200 m reel works out to a fraction of the per-job cost of sets

Cons

  • Multifilament frays and breaks far faster than poly if you hit heavy spin
  • A reel is a large up-front purchase that only pays back if you restring often

Don't buy this if…

…you break strings in under ten hours. You will be restringing weekly and should hybrid with a poly.

Pros

  • The octagonal profile gives the main strings edges to grab the ball with — this is the mechanism behind the spin, not marketing
  • Excellent snapback: the mains slide and return, which is what actually generates rotation
  • Holds up to full-swing topspin better than a round poly of the same gauge

Cons

  • Stiff like every poly — not a string for a sore arm in a stiff frame
  • The black coating sheds and marks the ball and the frame

Don't buy this if…

…you hit flat. You are paying for spin technology your swing does not use.

Pros

Cons

  • Less control than any polyester — big swings will send balls long

Don't buy this if…

…you break strings every few sessions. Hybrid it with a poly in the mains instead.

Pros

Gauge: thinner plays better, thicker lasts longer

String gauge runs backwards — a higher number means a thinner string. 16g (1.30 mm) is thick and durable. 17g (1.25 mm) is the club standard and the best compromise. 18g (1.20 mm) is thin, bites the ball harder for more spin, and breaks sooner.

If you break strings often, go thicker. If you never break strings and want more spin, go thinner. Most players should be at 17g, which is why most of this page is.

Sets or reels?

A set is roughly 40 feet — enough for one racquet. A reel is 200 m and strings about sixteen frames, at a much lower cost per job.

A reel only makes sense if you string your own racquets, or your stringer will work from string you supply. If you restring twice a year at a shop, buy sets: a reel will deteriorate before you finish it. If you string your own and have settled on a string you like, a reel is the single biggest saving available in tennis.

Stringing your own

At club restringing prices, a basic drop-weight machine pays for itself in roughly ten jobs. The Klippermateis the classic entry point — gravity-based tensioning that never needs calibration, made in the US for decades. The GAMMA Momentum 2 adds six-point mounting and swivel clamps, which matters if you are stringing for a family or a team.

Both are slow. Expect well over an hour for your first few frames and around 30–40 minutes once you are practised. That is the real cost, and whether it is worth it depends entirely on how much you value the money against the time.

What we cannot tell you

We have not strung these strings and played with them. What we have is the published construction — material, profile, gauge, the manufacturer's own description — and the physics of how each family behaves, scored against a rubric we publish. String feel is more subjective than almost any other piece of tennis equipment, and anyone claiming an objective ranking of it is overstating their case. Including us, if we did.

How we picked

We have not physically tested this gear

Everyone in this category says they tested twenty racquets. We have not tested any — and we say so. What we did instead: compiled the manufacturer-published specifications (head size, strung weight, string pattern, stiffness, outsole compound), normalized them, and scored each product against a published rubric weighted for the NTRP tier this page serves. The scores are judgments from documented research, not measurements we took, because we do not have a lab and are not going to pretend we do.

Questions

Frequently asked

What are the best tennis strings?
For most club players, a shaped polyester like Solinco Hyper-G Soft 17 — it gives control and spin at a price that makes frequent restringing affordable. For players with arm sensitivity, a multifilament such as HEAD Velocity MLT or Wilson NXT.
What is the difference between polyester and multifilament string?
Polyester is stiff, low-powered and high-control, and its sliding mains generate spin; it is hard on the arm. Multifilament is soft, elastic and powerful, and far more comfortable; it offers less control and breaks sooner. See our full comparison.
What string tension should I use?
Start in the middle of your frame's published range. Higher tension gives more control and less power; lower gives more power and comfort. Polyester should be strung about two to four pounds lower than a multifilament because it plays stiffer. The tension guide covers it properly.
Is natural gut worth the money?
For a player with chronic arm trouble, genuinely yes — nothing else is that comfortable while holding tension. For everyone else it is a luxury, and it is damaged by moisture, so outdoor players in damp climates get poor value from it.
