Ans: The grip size of a racquet is how big of a handle does the racquet has. It is usually denoted by G size. Higher the G number, bigger is the grip size. G4 is the standard size of grip size for most racquets. But the size number is dependent on how big or small the size of the hands of the players. Bigger hand player choose bigger handles where as smaller players choose smaller handles. The amount of wrist and finger space and movement also define the choosing of grip size. Smaller grip uses more arm power and is used for precision shots. Bigger grip size is for stability and flexible shafts.
