10 Best Tennis Strings : A Buyer’s Guide

tennis strings

Lawn tennis was the original name of tennis. In Britain, they still call it lawn tennis. It was played by Victorian gentlemen and ladies on lawn / grass courts.  

It is believed to be an evolved form of French handball. The original game has not changed much over the years. You could play the game as singles or doubles and had two opposing sides. There were rackets with taut strings hitting a ball over a net on a court.

Tennis is now played by millions around the world. Tennis has grown from a garden-party game for the elite to a mental challenge as intense as chess but with physical demands.

Professional players can earn tens of millions of dollars annually. The professional players rely on their stamina and skill as well as their equipment to withstand long matches.

One of the most important pieces of equipment is the tennis racquet used to hit the ball with precision back across the net trying to outwit the opponent.

Original rackets were made of wooden frames and used the outer skin of sheep intestines as strings. Pierre Babolat from Lyon, France was able to use his knowledge of musical string production as a platform for crossover to tennis strings.

There is still a company carrying his name, Babolat, which still makes tennis strings using intestine but now use cow’s intestines instead of sheep’s.

The shift to a cow over sheep occurred during World War II when sheep guts were limited. Cow intestines while are longer they are also stronger in tension.

For those who are concerned, the guts are procured as a by-product of meat production. The animals are not harvested solely for their intestines.

You would think this would make these rather inexpensive but just the opposite is true. Animal intestines are actually rather expensive.

Another challenge with using animal intestines as tennis racket stringing material is that under humid conditions the moisture in the air gets into the strings affecting their performance. This led to the development of “synthetic- gut” tennis strings.

Synthetic gut is nylon based tennis string and was developed when oil was less expensive. Nylon is twisted just as the intestines are. There are several advantages to a synthetic tennis string. You can increase durability.

Now the synthetic strings are multi-strands of nylon and manufacturers can increase the stability of tension in these strings far better than the original monofilament nylon string from the 1970s.

Tennis started to explode as it got more and more exposure on TV. The popularity of tennis was evolving from that of a game for the elite, as it was originally played, to that of a game, anyone could play.

As with anything when demand grows so does competition and that leads to better products for the consumer. Since the boom in the 1980s, the variety of tennis strings has exploded as well.

While traditional and synthetic animal intestine strings are still used on tour, there are now strings made of Kevlar, Zyex, Ventran, polyester and polyurethane (alone and in multiple combinations).

The different materials and the combination of materials make strings performance specifics such as strings that boast power, durability, comfort or spin. Players all have different preferences and there is a hybrid out there to meet each need.

Tennis String Buyer’s Guide


With so many different materials used in making strings, it is important to first look at what they are and what they mean to tennis strings.

Natural Gut (Animal Intestine)

the original tennis string, it was borrowed from stringed instruments. It is produced by drying out the serous membrane of an intestine and then stretching to form a string.

  • Softest even under high tension
  • Provides most energy return
  • Don’t lose rebound power under high tension
  • Absorbs some shock of ball/racquet impact
  • Outstanding tension retention
  • Expensive to produce
  • Weakens with off-center hits
  • Quality varies based on brand, batch, age, storage, and grade
  • Sensitive to moisture

Synthetic Gut

constructed of nylon and an inexpensive string in comparison to the natural intestine. Textured coatings, colors, and Kevlar have developed over the years.

It started out as a mono-filament string but to increase performance and get closer to mimicking actual intestines they have now evolved to multi-filament. This is the string closest to natural gut strings in tension and stiffness.


Stiff and durable initially intended for players who frequently break their strings. They are not very popular because they do not hold their tension.

Players who like a little extra topspin find the polyester strings serve that up keeping these strings from leaving the market altogether.

The reason for additional topspin can’t be found but through continued testing, it has been proven that polyester offers additional topspin. Researchers assume it is possibly due to the low friction between strings.


The stiffest and most durable. This synthetic string is extremely hard to break. Next to natural gut strings, Kevlar has the highest tension holding capability. It is also the least forgiving in shock absorption.

The highest rate of tennis elbow is reported from players using Kevlar strings, so beginners shoe be cautious if they are using a racquet with kevlar strings.

To try and increase shock absorption, Kevlar is often combined with other materials, decreased in diameter, or strung using less tension.


In terms of stiffness and durability, it is next to last. It is hard to find a player that uses this type of string. It is sometimes added to nylon to increase the durability of nylon and stiffness.


Good rebound efficiency especially when strung at low tensions. It has a low stiffness overall. There is a huge drawback to this string.

The inner materials do not bond with the wrapping materials and what happens is often the wrapping will wear away leaving the inner filaments exposed.


You will find that polyolefin used in tennis strings will make one of the softest strings. It has a middle of the road tension retention and durability. It is used often as a cross string in a hybrid string set up for people who do not break strings very often.

This less expensive string compared to natural gut and good for people who have suffered from tennis elbow.

String Construction:

Solid Core with Single Wrap – this is the most popular of the nylon string / synthetic gut construction.

  • Quality of nylon & wrap design affect comfort & feel
  • Maintains tension
  • Crisp feel

Solid Core with Multi Wraps – similar to single wrap but has more than one layer of wraps

  • Extra cushion and durability

Multifilament – bundles of unwrapped micro-synthetic fibers.

  • Similar to natural gut
  • More comfortable than solid core strings
  • Soft comfortable string
  • Great for players with tennis elbow
  • Tend to fray

Multicore with Wraps – multifilament string wrapped with one or more outer layers.

  • Soft
  • More durable than multifilament
  • Great for players with tennis elbow

Textured – textured outer surface on the outside of an extra filament, raised ridge, giving it a dented or rough surface.

  • Gives extra grip on ball
  • Enhances spin

Composites – for lack of a better term the “everything string”. They are made of combinations of materials.

  • Brings out the best features of each string used
  • Vary depending on construction materials

Monofilament Polyester / Co-Polyester – is a monofilament string made into a single strand.

  • Stiff
  • Best for advanced players
  • Great off center feedback
  • Best of all strings for spin
  • Co-Polyester’s low-friction coating enhances snapback
  • Shaped Polyester adds edges to grip the ball adding spin
  • Textured or Rough offer better grip equaling in more spin


The unit of measurement for string tension on a tennis racquet is pounds. It reflects the amount of pressure. There is a standard-setting of around 50 – 70 pounds. Rackets come with a recommended tension range.

It is recommended that beginners start in the middle of the road and play with it to find the tension best for their strength and sensitivity to ball feel. There are benefits though to rackets strung with more or less tension.

 Lower Tension

have a larger “sweet spot” and will generally hit farther. The drawbacks are that it can send balls off in unpredictable directions so are not so good for fine-tuned shots. So in short softer = more power and less control.

  • More Power
  • More Feel
  • More Comfort
  • Less Control
  • Less Durability

Higher Tension

with a strong swing, you can get control but you get less feel on the ball. While it will give you consistent power shots from the baseline long-term play with tight strings can lead to tennis elbow. Summing it up higher tension = lower power but great control.

  • More Control
  • More Durability
  • Less Power
  • Less Feel
  • Less Comfort

Over time, the elasticity of the strings will diminish. When it gets really soft they are known as “Dead Strings”. You will know you have dead strings when your racket’s performance starts to slide. You may lose power.

Your arm can become sore with the normal play because you have to provide the power the strings have lost. These are signs you need to get your racket restrung. How often you will need to have your racket restrung depends on you.

Some recommendations are to restring as many times in a year as you play in a week. So if you play 5 days a week you should restring your racquet 5 times in the year. Others recommend restringing after 40 hours of play.

Many clubs’ pro shops have string tension meters, and if you lose more than 25% is another recommended time to restring. There are also players who just wait until a string breaks.

String Diameter (Gauge)

The gauge refers to the diameter of the string. Gauge is measured in millimeters and / or gauge numbers. The higher the gauge number the thinner the string.

Thinner strings provide more power, feel and spin potential whereas a thicker string will give more durability and control.
