A professional badminton racquet’s dimensions are standardized by the Badminton World Federation (BWF). The standardization becomes mandatory at a professional level as there are various sizes available for kids, teens and adults.
There are five majors parts of a badminton racquet – the stringed area, head, throat, shaft and handle. As the name suggests, the stringed area is that part of the racquet with which the shuttlecock makes contact. The strings are bound by a frame which is 280 mm in length and 220 mm in width.
The head is generally isometric in shape and is broader at the top. It has an ovoid shape which helps in imparting a greater power. The next part is the throat which is optional. Its role is to stabilize the head of the racquet and it’s width must not extend 35 mm. The shaft is what connects the head with the handle. There are no specifications for the handle except that the maximum diameter cannot exceed 25.4 mm. The grip on the handle contributes to the weight balance of the racquet. The two types of grips in racquet are over-grips and replacement grips and they differ based on the material used.
The BWF further states that no additional objects can be stuck, applied or taped to any part of the badminton. The maximum length of the badminton racquet cannot exceed 680 mm. Professional shutters use a racquet length which usually ranges between 665 to 675 mm.
The weight of the racquet does not exceed 70 to 95 grams excluding the strings and the grip. This depends a lot on the type of material used for the manufacturing of the racquet. These materials range from wood to solid steel to graphite reinforced plastic.
