Choosing the correct badminton racket is down to personal preference, but the following is a general guideline.
What weight do I choose?
The weight is denoted by the "U", the smaller the number the heavier the weight.
A lighter badminton racket allows for more manoeuvrability, which can suit players who are slow to change grip or struggle to change defence into attack. It is also easier to be deceptive with a lighter frame.
A heavier badminton racket allows for greater power generation as a larger force can be transfered into the shuttle. Players who struggle to generate power may choose a heavier racket.
However, most rackets are inbetween the two extremes, as a medium weighted racket will allow for both power and control.
You will find most medium weighted rackets are between 84g-88g.
What balance should I choose?
Generally a head heavy racket gives more momentum through the swing to develop power and would therefore be suited to players who like to hit hard. Whilst a more balanced racket would give more feel and decent power.
What grip size should I choose?
The grip is denoted by the "G", the smaller the number the larger the handle size.
A smaller grip size allows for a greater feel of the racket and therefore it is easier to produce deceptive touch shots. A smaller grip means more flexibility and manoeuvrability in the hand.
A larger grip size allows for the racket to be held tightly, therefore making it feel more stable in the hand.
What stringing tension should I choose?
