What does Flex mean in badminton rackets


Flex refers to the amount of bend point in a badminton racket’s frame. Flex is important because it determines the power and control of shots during play. Flex also affects how fast and how far a shuttlecock will travel after being hit by a racket.

Different players prefer different levels of flex, depending on their style of play and their level of skill. Generally, beginner players require more flexible frames for greater control, whereas experienced players require stiffer frames that provide greater power but less control. Flexibility can range from very soft or flexible (number 4 and below) to stiff (number 8 and above). Stiffer rackets also tend to be heavier than lighter rackets with a higher flex rating.

It’s important to consider your style when selecting the right racket for you.

What is Flex?

Flex is an important element to consider when choosing your badminton racket. The flex of the racket affects how the racket will bend, which affects the speed and power of your shots. The flex of the racket varies from racket to racket and can range from stiff to very flexible.

In this article we will discuss what flex is and why it is important for badminton rackets.

Types of Flex

Flex is an important factor to consider when choosing a badminton racket. It is an indicator of the flexibility and rigidity of a badminton racket’s frame, which can affect the power and control of your shots. In general, if the racket has more flex, it provides better control; whereas a stiffer racket has more power. It is usually measured in numbers on a scale from 1 to 9, with higher numbers representing greater flexibility. However, this scale varies depending on the manufacturer of the racket.

The type of flex that’s right for you will depend on your playing style, strength and preference. If you’re an aggressive player who plays with a lot of power, then you might want to opt for less flex (around 5). On the other hand, if you prefer control over power, a higher flex (7 or 8) could bring some improvements to your performance by reducing shock and increasing accuracy.

The three main types of flex include:

  • Hyper-Flex: This is the most flexible type and offers excellent feel and comfort as well as dynamic tension control at impact. This makes it ideal for players who are looking for maximum responsiveness from their equipment.
  • Mid-Flex: This type provides excellent maneuverability while still offering good stability at combination shots.
  • Contact Point Flex (CP): Also known as Medium Flex or Bending Point Flex (BP), this type ideally falls in between hyper flex and stiff flexible rackets. Players who prefer a balance between power and accuracy will find this to be beneficial as it can help them maintain pinpoint accuracy while maintaining fast swingspeed qualities during their shots.

Stiff Flex

Flex ratings measure how much a badminton racket bends when it makes contact with a shuttle. The higher the flex rating, the more the racket bends on impact. Rackets are arranged in four tiers: extra stiff, stiff, medium, and flexible.

A .1 Stiff Flex rating means that the racket will flex slightly more than an Extra Stiff Flex. It is still considered to be on the stiff end of the spectrum and is typically used by advanced players who are looking for extra power and control on their shots. Depending on the brand of badminton equipment you choose, this will affect how you play as well as your comfort level when using the racket.

Medium Flex

.2 Medium Flex refers to the shaft of a badminton racket and determines how flexible it is when the racket is held in the playing position and the head is fully loaded. This flexibility affects the power, speed and accuracy of shots played with the racket.

A .2 Medium Flex has a combination of control due to its stiffness, but still has a bit of flexibility in order to generate power from your shots. It also provides good accuracy in both attacking and defensive shots. The .2 Medium Flex is suitable for players that have developed their basic skills but are looking for more precision and power for intermediate level play.

Soft Flex

The 3 Soft Flex in badminton rackets means a racket frame with limited flexibility. Also referred to as stiff flex, this type of badminton racket provides stiffer frame construction compared to other strings, thanks to its highly advanced material technology. It helps the player develop a more powerful shot during tough rallies or smashes and transmits significantly less shock when hit by an opponent’s shuttlecock.

The racket’s stiffness can also help players generate greater string bed tension, producing better control and accuracy during play. Players who prefer heavier swings or longer reach are often accustomed to using this type of flexible frame as it offers power transfer and control within one single structure with performance focused efficiency.

How Does Flex Affect Performance?

Flex is an important factor to consider when choosing a badminton racket as it impacts the performance of the racket. Flex is a measure of how much a racket bends when it is hit, with higher flex meaning the racket will bend more when it strikes the shuttlecock. Different flex ratings affects the power and control of the racket, so it is important to know how these factors will impact your performance when choosing a racket.

Let’s look at how flex affects performance in more detail:


Flex, also known as frame stiffness, is the amount of stiffness in a badminton racket frame when flexed. The higher the flex rating, the stiffer the racket frame. It is measured using a device that determines how far down on an axis the racket Flexes under load force.

A softer Flex results in more power and flexibility but less control. A stiffer Flex leads to better precision with shots but gives less speed to your shots as compared to a more flexible racket frame.

A racket designated as ideally suited for power players would typically have increased stiffness within its range of possible Flex ratings. This type of racket can provide great power and control while still maintaining good flexibility and moderate power output during a rally or match play. Therefore, choosing the correct Flex rating for your specific playing style can help you unlock potential for improved performance in badminton games!


Flex, measured in units of stiffness and rigidity, is a key factor for any serious badminton player when selecting a racket. It ultimately affects how much control the player has when hitting the shuttlecock.

Increased flexibility (as found in lower flex rackets) results in more power and spin to shots due to faster string bed response. On the other hand, higher flex rackets will offer more control of the shuttlecock at a slower swing speed.

Having too low of a flex can lead to inaccurate aiming while having too high of a flex can cause less power and heavy swings. Therefore, it is important that you choose your racket carefully by taking into account your level of skill, hand size and playing style.

  • Recreational players may find that medium stiff or stiff racquets are best for obtaining precision during shots as well as adequate control for longer rallies.
  • In contrast, advanced players might prefer really flexible rackets which will require more skill yet provide greater power or better placement when hitting shots from backcourt areas.

The notion that comfort and performance are closely related is applicable in the badminton world, too. With regard to racket frames, it means that a lower amount of flex results in better shock absorption, resulting in less vibration and less fatigue on the arm. Additionally, it generally makes for a lighter frame.

Racket frames usually range from 18 to 38 points of flex (lower numbers represent more flex). A racket’s weight affects the flex of the frame; heavier rackets are usually stiffer with less flex than lighter rackets which tend to have more flexibility.

In general, badminton gear with a lower flex rating will provide more comfort and shock absorption than stiffer gear. This is because higher-flex frames provide greater repulsion power on shots due to their stiffer construction – meaning that it requires more effort for shots to travel through the air as opposed to softer frames which allow for shots to stay airborne longer with fewer strokes.

So when selecting your badminton gear, you should take into consideration not only power but also comfort; seek out rackets with both qualities – high repulsion power and low points of flex – so that you get both a controlled and comfortable game experience!

How to Choose the Right Flex for Your Racket

Selecting the right flex for your badminton racket is an important decision that can affect your game. The flex of a badminton racket refers to the amount of power it can generate and how it will feel when you hit the shuttle. Knowing the different types of flex available can help you make an informed decision when choosing the best badminton racket for your needs.

Let’s find out what flex means in badminton rackets.

Playing Style

In order to determine the optimal badminton racket flex for your playing style, it is important to understand how flexibility affects the performance of your racket. Different playing styles require different amounts of flex in order to maximize speed, power and control.

  • Power – The more flexible a racket is, the more power can be generated when striking a shuttlecock; however with more power comes less control. If you are looking for powerful smashes with low control then a stiffer racquet may be better suited for you.
  • Control – A stiffer or less flexible racket will provide more control as the shuttles’ flight path will remain relatively straight due to less torque being applied on the shaft. This makes it easier to place shots accurately.
  • Speed – Generally speaking, stiffer rackets are faster than flexible rackets as less energy is lost when striking shots due to their higher tension levels. To improve speed during a match, consider combining this with a lightweight frame and strings that offer excellent response and repulsion characteristics.

By understanding how the flex of your badminton racket affects its performance, you are better able to identify and choose the best suited one for your playing style and ensure maximum success when competing against opponents out on court!

Physical Attributes

Your physical attributes, such as height, weight, flex of your arm and power generated are important factors to consider when selecting the right badminton racket. Generally, if you are a taller player with a strong flex in the wrist who generates powerful forehands and smashes the best flex for you would be stiffer than average (2U or 3U). If you are an average weight player with normal forearm strength, who likes to play with steady and controlled strokes a medium flex (3U) would be best suited for you. Shorter players or those who generate less power should select a situation racket such as extra-stiff (4U) when available.

It is also important to note that brands may vary in their degree of stiff or flex measurement described earlier, so it is important to try out different rackets before making a final decision.

Skill Level

Flex, or stiffness, refers to the flexibility of a racket’s shaft. The lower the flex rating is on a racket indicates higher flexibility and a lower power transfer for greater control. Higher flex ratings offer stiffer shafts for more power transfer but with less control and less accuracy.

Skill level plays an important role in choosing the right flex for your racket, as powerful play requires more control and accuracy at higher levels.

For players at the beginner to intermediate level, there is no need to choose a highly flexible racket because they lack the skill needed to generate power from it yet. For these players, light-flex rackets are recommended as they offer an easier swing but still provide good power without requiring advanced technique and coordination.

Intermediate players will likely benefit from a medium-flex model which provides slightly more powerful play with improved control while not being too powerful or difficult to handle.

At the advanced level, high-flex models may be necessary in order to generate maximum power and technical precision on shots with extreme trajectory angles from both sides of court. At this level it’s important to test different flexes of rackets in order for players to find their ideal combination of flexibility and power transfer that suits their style of play best.


The flex of a racket is a measure of the amount of flexibility taken from the frame when the racket is swung. Each racket will have a different degree of flex and should be chosen based on your playing ability, purpose for playing and strength.

Generally, a flexible racket offers more power but less control and so is more suitable for experienced players. A stiffer racket offers less power but more accuracy, thus making it more suitable for novice players.

When selecting a badminton racket, it is important to determine what type of player you are in order to choose the right flex for your game:

  • Novice players – stiffer racket
  • Experienced players – flexible racket
