Choosing the right string can make a very big difference to your court sport game.

It can affect the power and the control offered by your string and even allow your racquet and string to fit better with your own well-earned skills.

But with all the various strings used in different court sports, it can be hard to tell the difference between them and just how they benefit your game.

Looking at squash strings vs tennis strings can help distinguish two of these favorite sport’s strings from each other.

The right string matters

Though both tennis and squash will require a string that suits your racquet and your needs for power versus control, they are not interchangeable.

All court sports that require a racquet and string may often present their playing style and their strategies in a similar manner.

Even the similarities between the traits of their strings and how the strings are made can make the two sports’ strings seem identical.

Yet even with all these similarities it is best to use only the string specifically designed for each sport.

Specific string is designed to fit into the racquet and provide the player with the equipment to succeed.

Small details like tension and diameter are crucial to distinguishing any string type.

When looking for what string to use it is important to notice both of these features along with the materials used to construct the string, the string’s outer wrap and core design, and layers of texture.

These features will impact whether the squash or tennis string offer more power or control.

Both power and control can benefit players during either sport. However, strings are often designed with their features that only push one of these.

This is because power and control are supported by different, opposing traits within the strings tension, diameter, and composition.


The tension of any racquet string works as a big component to the strings ability to provide power or control.

Tensions of strings range depending on the string type being used and also on the shape and sizing of the racquet.

The higher a racquet string’s tension is set, the more control it will offer. This is caused by the higher tensions pulling the strings into a tight formation.

When the sport’s ball connects with the racquet’s strings, they will not give.

Instead, the ball will rest on the strings without an extra push to spring it back. This allows for more time on the strings, which gives the player more time to accurately place the ball.

Lower string tensions support the opposite factor, allowing for great use of power.

When the tension to the racquet’s strings are lower, they are able to better conserve and redirect energy coming from the ball.

When the ball impacts the strings, they will act as a conserving force to save the power the ball has before springing it back with even more force and speed.

Tennis strings and their racquets allow for a wide range of tension settings for players to select from.

This range extends from 45 to 75 pounds worth of tension. players can easily select the needed tension that will best suit their playing style.

A squash racquet and string will not go this high or provide this amount of variety.

Overall, squash players do not need to drastically change their tension as each person will often require a similar setting.

This leaves the tension options between 24 and 30 pounds on average. This is a much more limited and lower tension option than that of tennis strings.

Lower tensions like these will offer a strong sense of power.


Diameter of a string will determine how thick or thin a string is. Strings are sized to fit within their assigned racquet, making their diameter a very important and distinguishing feature.

The diameter will also show if a string is made for power or control along with how durable the string is.

Thinner strings are bound to be less durable than that of thicker strings. They had less material and felt the force of shots from.

The strings can wear through quite quickly if they are made extremely thin and will need to be replaced often.

Thicker strings last much longer than thinner ones as they are more durable.

Thicker strings also offer more control. Much like a higher tension in a string will allow for longer contact between the ball and the string, thicker strings will allow longer contact over more surface area.

Thinner strings will provide both squash and tennis players with more power though.

This power is great for all playing levels to benefit from.

The diameter of a string is measured in millimeters and labeled as the string’s gauge number. These numbers increase as the thinnest of the string increases.

When looking at tennis strings, the gauge number can range from 15 to 22, leaving a lot of string options to choose from.

Tennis strings will also offer what is known as a light string gauge number.

This is a lighter version of a gauge number indicated with the gauge number being followed by an “L” on the string’s label.

The tennis strings’ gauge numbers range from a thinnest of 0.6 millimeters to a thicker 1.49 millimeter.

Squash strings do not offer as wide a variety much like their tension options.

They are more limited as players do not need as much individuality in their equipment in order to perform well.

The gauge numbers range from 16 to 18 for only a few thickness options. These options fall between 1.1 and 1.3 millimeters.

Wrap and core

One common trait between squash and tennis strings, and all other court sport based strings, is their construction.

Strings are often made the same way with a few material options.

These options can feature small changes from brand to brand but ultimately come from the same basic starting point.

Both strings are either multifilament or monofilament. This refers to the number of materials used within the string core and its outer wrap layer.

A multifilament string will use multiple material options in order to create a stronger, more durable, and made for good power and stronger control.

Monofilament strings feature only one single string material to provide extreme power, great feet and decent durability.

Either string type can use either a natural gut material option or synthetic materials.

Natural gut comes from the intestines of animals, like cows and sheep. It is more durable and better amplifies the string’s greatest traits.

But it is also more expensive.

Synthetic materials are cheaper and offer similar features to that of natural gut.

Synthetics like nylon or polyester can be used to improve durability and increase the feel of your string.

The core of your string is also important. The core can be solid as either a multifilament or monofilament, or it can be empty.

Non-solid cores are not as popular as they do not offer as strong a durability as other solid cores do.

Solid cores are more durable as they provide an extra layering of material that can withstand shock and does not allow the string to wear down so easily.

The outer layer of a string can also be a great way to generate spin, something very important when it comes to playing tennis.

Having a natural spin to your tennis shots can help increase the force of your shots and make it more difficult for your opponent to retrieve and return your shots.

Spin can occur whenever an outer layer of the string’s wrap offers a texture.

While tennis is the most recommended sport to need spin, other sports like squash can also benefit.

Squash strings vs tennis strings

Looking through the features more closely proves just how different squash strings are from those strings used in tennis.

Tennis strings offer a variety of diameters which are shown with gauge numbers.

These numbers fall from 15 to 22, with lighter diameters shown with an “L” beside the gauge numbers.

The diameters offered by tennis strings are from 0.6 millimeters to 1.49 millimeters.

Tennis strings often feature a texture on their outer layer in order to generate more natural spin to their shots.

These strings can also be set to a variety of tensions from 45 to 75 pounds.

Using either a multifilament or monofilament with no core or solid core these strings are made with materials that are either natural gut, nylon, polyester, or other synthetic materials.

Squash ball strings also offer natural gut and synthetic composition options.

These, like a tennis string, can be constructed as monofilament or multifilament strings.

However, they have a much lower tension option that players can set the strings to due to the racquet’s shape and the string’s length within the squash racquet.

This tension falls between 24 to 30 pounds.

The gauge numbers of a squash string are also more limited, between 16 to 18 gauge. These gauge numbers are used to represent the string’s thickness from 1.1 to 1.3 millimeters.
