The choice of grip allows a player to increase the thickness of his racquet handle and choose a comfortable surface to hold. A player may build up the handle with one or several grips before applying the final layer.
Players may choose between a variety of grip materials. The most common choices are PU synthetic grips or towelling grips. Grip choice is a matter of personal preference. Players often find that sweat becomes a problem; in this case, a drying agent may be applied to the grip or hands, sweatbands may be used, the player may choose another grip material or change his grip more frequently.
There are two main types of grip: replacement grips and overgrips. Replacement grips are thicker, and are often used to increase the size of the handle. Overgrips are thinner (less than 1 mm), and are often used as the final layer. Many players, however, prefer to use replacement grips as the final layer. Towelling grips are always replacement grips. Replacement grips have an adhesive backing, whereas overgrips have only a small patch of adhesive at the start of the tape and must be applied under tension; overgrips are more convenient for players who change grips frequently, because they may be removed more rapidly without damaging the underlying material.
The proper grip size to use depends greatly on the player. Obviously a player with larger hands will prefer a larger grip and vice versa. It is often tempting to use a large grip, a large grip gives the false feeling that the racket is lighter and more maneuverable. However, one must again understand that badminton is comprised of subtle, agile and delicate movements in the fingers and wrist, a smaller (but not too small) grip will allow for higher agility and maneuverability of the racket.
