The racket surface MID is 95 square inches, the MP is 96-100, and the OS racket surface is on top. Namely Mid, Mid-plus, Over-size.
Generally speaking, novices and weak ladies are recommended to use OS to beat the face. The hitting area is large, the dessert is large, and it is easy to receive the ball. And because of the large racket surface, the power is dispersed even after the ball touches the net. The effect of unloading force is obvious, and it is convenient to take advantage of force. However, due to the small dessert, the MID racket has high requirements for technique and strength when hitting the ball. But when the ball is hit, the more concentrated power can facilitate the strong players to hit the violent heavy blow. Therefore, most of the rackets on the MID surface are heavy-weight rackets, specially equipped for violent players. The MP racket can be said to be the most mainstream racket today, and it can be used by anyone from an expert to a rookie. It can be selected according to its own characteristics.
Length: The standard shot length is 27 inches (inch) / 69 cm (centimeters). In adult shoots, there are no short ones, only lengthened ones, just to lengthen the moment arm. Increased demands on power can bring greater power to serve and hit. Zhang Depei was the first to try the extended shot, so he increased his serve speed to 120 mph. The most famous of the extended shots is the extended POG, that is, Zhang Depei’s generation, and the PD+ endorsed by Roddick. However, novices are not recommended to use PD+. Uncoordinated movements can easily get tennis elbow.
