BADMINTON RACKET PARTS AND ITS FUNCTION
The stringed area is made up of nylon or carbon fiber string that is interwoven to form the face of the racket. Its dimensions, according to BWF rules, must not exceed 280 millimeters in length or 220 millimeters in width. Throat
The throat connects the head to the shaft. It may be a separate triangular piece at the base of the head, or may actually be integrated into the head itself. Shaft
The shaft is the long rod between the throat and handle. Often made of a composite material such as graphite, the shaft can be stiffer or more flexible based on the needs of the player. Handle
The handle connects to the shaft and is used to hold the racket. The handle is covered with a material called the grip. There are two types of grips: towel grips are good for absorbing moisture, but may need to be changed frequently; synthetic grips are less absorbent but more durable.

At the beginning of the game (0-0) and when the server’s score is even, the server serves from the right service court. When the server’s score is odd, the server serves from the left service court. If the server wins a rally, the server scores a point and then serves again from the alternate service court. If the receiver wins a rally, the receiver scores a point and becomes the new server. They serve from the appropriate service court – left if their score is odd, and right if it is even.
A side has only one ‘service’.
The service passes consecutively to the players as shown in the diagram. At the beginning of the game and when the score is even, the server serves from the right service court. When it is odd, the server serves from the left court. If the serving side wins a rally, the serving side scores a point and the same server serves again from the alternate service court. If the receiving side wins a rally, the receiving side scores a point. The receiving side becomes the new serving side. The players do not change their respective service courts until they win a point when their side is serving. If players commit an error in the service court, the error is corrected when the mistake is discovered. In a doubles match between A & B against C & D. A & B won the toss and decided to serve.
