Racquet length
Length refers to the distance between the top of the head and the bottom of the racquet handle. This indicator for most rackets for adults is in the
range of 68-69 cm. Longer models in fact can provide a stronger hit, especially when serving, but are more difficult to manoeuvre during play. The International Tennis Association does not allow racquets longer than 74 cm to be used in tournaments.
String surface area
There is a simple pattern here: the larger the area of the string surface and the lower the rigidity of the string tension, the higher the impact force and the lower its accuracy. This parameter is directly related to the string formula.
Now on the market there are rackets with the following string surface area:
Midsize (452 – 574 cm²),
Midplus (580 – 677 cm²),
Oversize (710 – 742 cm²).
Weight
As the weight of the racquet increases, the impact force increases, but its accuracy decreases. On the contrary, it is easier to swing
with a light rocket, but at the same time, the player needs to make more effort to give the ball the desired speed.
