Types Of Tennis Strings

Tennis strings have the following five important types;

  • Natural Gut
  • Multifilament
  • Polyester
  • Synthetic Gut
  • Hybrid

Let’s introduce you to each type and discuss each type separately;

Natural Gut

Natural gut is one of the best available strings in the market made up of animal intestine (Mostly Cow) drying fiber. tension retention of the natural gut is exceptional compared to other strings and softer than any other material. However, Natural gut string is an expensive option for the user.


Let us look at the best multifilament tennis string; Multifilament is made-up of more than one filament like Nylon, Polyurethane, Zyex, etc. Multifilament is best known for its comfort & power and is especially recommended for players suffering from an injury. it has good durability and best tennis string for power and control.


Unlike multifilament, if we look over the best polyester tennis strings, It is made up of a single solid filament. The polyester string is viral in the market and is known good for its durability, spin, control, and cuts.

Polyester is hard compared to natural gut & multifilament and becomes strict to your arm and is known as the best tennis string for control.

Synthetic Gut

The synthetic gut is nylon and made up of a single filament. Nylon is very cheaper as compared to other strings, and usually, it is the best tennis string for beginners. The synthetic gut has dynamic stiffness and good all-around performance.


Multifilament and natural guts have good power and comfort but a lake of spin while polyester has especially of spin and cuts, but it is hard for the arm. So, sometimes it becomes very difficult for players to pick and choose as they want to avail both options. So, when we combined two strings, it becomes a Hybrid.

Hybrid is the best spin option for players, along with comfort. It’s the best choice for players in the current era.

What Is Tennis String Gauge

Tennis string gauge refers to the thickness of the strings on a tennis racquet. The string gauge ranges from 15 to 19.

The choice of string gauge is a matter of personal preference and can affect the playability and performance of the racquet. Thinner strings offer more power and a softer feel, but may break more easily. Thicker strings provide more control and durability, but may lack the power and feel of thinner strings.

The type of player and playing style can also influence the choice of string gauge. For example, players who rely on spin and power may prefer thinner strings, while players who prioritize control and durability may prefer thicker strings.

It is important to note that string gauge is just one factor that can affect the playability and performance of a racquet. Other factors include the string pattern, string material, and overall racquet design.

Experimenting with different string gauges can help a player find the combination that works best for their game.

being an important factor, it will affect multiple game factors like;

  • Spin
  • Power
  • Control
  • Durability

Ultimate Guide to Tennis String Tension

Tennis string tension refers to the amount of force that is applied to the strings of a tennis racquet when they are strung. The proper string tension can have a significant impact on the performance of a tennis racquet.

So, If the strings are too loose, they will not transfer energy effectively and the player may experience a lack of power and control. On the other hand, if the strings are too tight, they may cause the racquet to feel stiff and unresponsive and may also increase the risk of injury to the player’s arm.

String tension for racquets is normally from 40-70 Pounds. however, the ideal string tension will vary depending on the player’s style of play, skill level, and personal preferences. Some players may prefer a lower tension for more power and forgiveness, while others may prefer a higher tension for more control and precision.      

String selection for Beginners

Beginners normally select cheaper and more comfortable strings at their startup, so they will go for Nylon or Multifilament, which will provide them with soft and comfortable playability.  

String selection for Intermediate & Advanced players

The intermediate and advanced level player will go for hybrid and natural gut strings. As time passed, they will get more experience in their game, and experienced players need a combination of comfort, control, and spin, so they will go for hybrid and natural guts strings.

What Does Tennis Racket Restringing Mean?

Tennis racket restringing refers to the process of replacing the strings in a tennis racket. strings lose tension over time, and if you are a player who loves to play with higher tension strings for better control and accuracy and when you feel that your control is losing because of low tension so you will definitely proceed with restringing.

Moreover, many players might choose to restring their racket because they may want to try a different string material or gauge, or they may want to adjust the string tension to better suit their playing style.

Restringing a racket involves removing the old strings, choosing new strings, and installing them in the racket using a specialized stringing machine. Restringing can be done by a professional stringer or by the player themselves, using a portable stringing machine.

Restringing can also be a good opportunity to check and adjust the overall condition of the racket, such as the grip, grommets, and bumper guard.

Restringing a racket can help to improve its performance and prolong its lifespan. It is generally recommended to restring a racket every few months, or more frequently for players who use their racket extensively.

Most Common Tennis Stringing Pattern

Tennis racquets strung in a criss-cross horizontal-vertical pattern. Vertical strings are called the main strings that run from throat to tip, while horizontal strings are called cross strings.

The tennis string pattern is always shown as vertical strings multiply with horizontal strings [i.e., Main-string x Cross, 16×18].

Tennis stringing pattern has mainly two types,

  • Open String Pattern
  • Dense string Pattern

Let us introduce and define each type for your better understanding,

Open String Pattern

Open string pattern has fewer vertical strings as compared to dense. Open string pattern commonly is 16×18 and 16×19. In an open string pattern, squares or spacing are larger. The main advantage of the open string is you can get a good amount of spin and power.

Dense String Pattern

The denser string pattern number of vertical and horizontal strings is more than open string patterns, normally like 18×20. So squares and spacing are smaller, which will make a denser pattern. The denser string pattern is preferred by players who are having the expertise to play flatter shots. 

Final Thought

The tennis racquet string is the main and integral part of the racquet, which is directly related to the functionality of the games like power, comfort, control, and spin. Players choose strings types and patterns as per their game expertise, experience, and way of playability.
