Polyester vs. Multifilament Tennis Strings (Guide)

The game of tennis is largely impacted by the selection of tennis strings. Different types of strings yield different outcomes on the court.

We look into the two most commonly used tennis strings – Polyester and Multifilament.

Overview of Tennis Strings

Tennis strings are a critical component of a tennis racquet.

They directly influence the player’s performance.

The two prominent types of strings are Polyester and Multifilament.

Polyester Strings

Polyester strings are a popular choice among professional tennis players.

These strings are known for their durability and control.

Polyester strings are made from a synthetic material known as polyethylene terephthalate.

These strings are particularly known for their firmness and resistance to wear and tear.

One of the major advantages of polyester strings is their ability to produce incredible spin.

This is due to the sliding effect they have when coming into contact with the ball.

However, polyester strings are less comfortable to play with, as they generate less power and can be tough on the arm.

This could lead to injury if the player is not accustomed to them.

Multifilament Strings

On the other hand, multifilament strings are made up of hundreds or even thousands of microfibers.

These microfibers are woven together to create the string.

Multifilament strings are known for their excellent power and comfort.

They generate a higher level of power than polyester strings.

These strings are more elastic, which gives a better ‘feel’ when hitting the ball.

This elasticity also leads to better shock absorption, reducing the risk of arm injuries.

However, multifilament strings are less durable than polyester strings.

They are more prone to breakage and wear out faster.

What Kind of Strings Do Top Tennis Players Prefer?

Top tennis players have varying preferences when it comes to tennis strings, and their choices depend on factors such as playing style, court surface, personal feel, and individual needs.

However, it is worth noting that many professional players tend to use polyester strings due to their durability, control, and spin potential.

The stiffness of polyester strings allows them to generate substantial power and spin, which can be advantageous for players who rely on aggressive shot-making.

Additionally, polyester strings’ ability to maintain tension well over time is beneficial for consistent performance during long matches.

However, it’s important to remember that string preferences can differ among professionals, and some players may opt for multifilament strings or even hybrid setups to find the perfect balance of power, control, and comfort that suits their game.

Comparing Polyester and Multifilament Strings

When comparing polyester and multifilament strings, one needs to consider their playing style and what they value most in their game.

For players who rely heavily on spin and control, polyester strings might be the best choice. They also suit players who frequently break their strings, due to their superior durability.

On the other hand, players who prioritize comfort and power might prefer multifilament strings. These strings are also great for players who have a history of arm injuries, due to their excellent shock absorption.

Multifilament or poly strings? Which one should you choose and why…


In conclusion, both polyester and multifilament tennis strings have their unique advantages and disadvantages.

The choice between the two should be based on the player’s skill level, playing style, and personal preferences. Always remember, the right string can significantly improve your game.

FAQs – Polyester vs. Multifilament Tennis Strings

1. What is the difference between polyester and multifilament tennis strings?

Polyester and multifilament are two different types of materials used in the construction of tennis strings.

Polyester strings are made from a single solid filament of polyester material, while multifilament strings are composed of multiple smaller filaments woven or bonded together.

2. Which type of string offers better durability?

Polyester strings are generally known for their exceptional durability.

They have a reputation for being more resistant to breaking or fraying compared to multifilament strings.

This durability makes them a popular choice for players who generate a lot of power or frequently hit with heavy topspin.

3. Are multifilament strings more comfortable to play with?

Yes, multifilament strings are often considered more comfortable to play with compared to polyester strings.

The multiple filaments in the string construction provide better shock absorption, resulting in reduced vibrations and a softer feel.

This can be particularly beneficial for players who have arm or shoulder issues or those seeking a more forgiving string bed.

4. Which type of string offers better playability?

Playability can be subjective and depends on personal preferences. However, multifilament strings are generally known for offering better playability.

The softer and more responsive nature of multifilament strings can enhance the touch and feel of the ball, allowing for better control and shot placement.

Polyester strings, on the other hand, tend to be stiffer and offer more control-oriented characteristics, which some players prefer.

5. Do polyester or multifilament strings offer more power?

Polyester strings are typically considered to be less powerful compared to multifilament strings.

The stiffness of polyester strings results in less trampoline effect upon ball impact, which can reduce the power generated.

Multifilament strings, with their softer construction, tend to provide more power and generate greater ball speed, making them a popular choice for players looking to add more pop to their shots.

6. Which type of string is better for players with arm injuries?

For players with arm injuries or sensitivities, multifilament strings are generally recommended.

The softer and more forgiving nature of multifilament strings helps to reduce the impact and vibrations transmitted to the player’s arm.

Polyester strings, due to their stiffer composition, can transmit more shock and may exacerbate arm discomfort or potential injuries.

7. Are there any differences in string tension maintenance?

Polyester strings are known for their excellent tension maintenance properties.

They tend to hold tension well over time, providing consistent performance throughout the string’s lifespan.

Multifilament strings, on the other hand, are typically more prone to losing tension faster, requiring more frequent restringing to maintain optimal playability.

8. Which type of string is more suitable for spin generation?

Polyester strings are highly regarded for their ability to generate spin.

The inherent stiffness and lower elasticity of polyester strings allow the player to grip the ball better, creating more bite and spin potential.

This is particularly beneficial for players who rely on spin-heavy shots, such as topspin or slice.

9. Are there any differences in cost between polyester and multifilament strings?

In general, multifilament strings tend to be more expensive than polyester strings.

The manufacturing process and the materials used in multifilament strings contribute to their higher cost.

Polyester strings, on the other hand, are more affordable and often considered a cost-effective option for players looking for durability and control.

10. Can I mix polyester and multifilament strings in my racket?

It is possible to hybrid string a racket by using polyester strings in the mains (longitudinal strings) and multifilament strings in the crosses (horizontal strings).

This setup can offer the benefits of both types of strings, providing durability and control from the polyester mains and comfort and playability from the multifilament crosses.

Hybrid stringing allows customization to suit individual preferences and playing styles.
