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.
Handle size
It is customary to read that the thickness of a tennis racquet should be such that when it is grasped between the fingers and the palm there is a gap slightly larger than the thickness of the index finger. There are two generally accepted systems for measuring handle thickness: American and European. If within the first one, the indicator is measured in inches, then within the European one — in integers from 0 to 5, where zero is the smallest size. Usually, each racquet is presented on the market with modifications with a different handle diameter. So, the indicator "1-5" means that the model is represented by modifications with a handle diameter of 1, 2, 3, 4, 5. Exceptions may be some children's rackets, for which the manufacturer sometimes does not indicate the diameter of the handle, since it is less than size 0.
