1. Low weight (i.e., less than 20 pounds)
Advantages: Excellent elasticity regardless of the type of wire used.
Flaw: The string tension is very loose, and the directional control of the ball is poor. As long as the ball is not hit in the sweet spot of the badminton racket, there will be a certain deviation in the flight method of the ball from the swing, and it cannot be precisely controlled the location of the ball, even if the same force is used to hit the same ball, the location of the ball will not be the same.

2、Low to Medium Weight (i.e., 20-23 pounds)
Advantages: The feel of the swing is good, and the ball control is also good.
Flaw: There is a sense of being stuck. Suitable for amateur players, as it is not suitable for aggressive players due to the sense of being stuck.

3、Medium weight (weight between 23-25 pounds)
Advantages: At this weight, both the string and the racket can fully exhibit their unique performance characteristics. Most amateur players use this weight, and you start to feel the elasticity when swinging the ball.

4. Medium to High Weight (i.e., Pounds between 25-27)
Advantages: The sense of ball retention on the racket face is significantly reduced, leading to good control and accurate hitting.
Flaw: The hardness of the racket face can be felt at this weight, and the elasticity of the strings decreases, making the swing feel less powerful.

5、High Pounds (over 28 pounds)
Advantages: exceptional ball control, extremely accurate hitting, as if the ball follows the trajectory in one's mind, which is the pinnacle of badminton playing. This requires strength (explosive power and wrist strength), core strength, and body coordination. Not everyone can play with high tension, but if they can, it at least shows that they can play well, and the majority of experts are able to do so.

In summary, if you are a beginner, when choosing the poundage of a badminton racket, you can start from low poundage and gradually increase to medium and then high poundage. Do not start with high poundage. Beginners may easily injure their wrists when using high poundage. It is recommended to start with low to medium poundage, and a racket with less than 20 pounds feels like the ball is completely out of control.
