To get the best out of your racket you’ll have to do a little more than just use the best string.
The choice of the right tension is about as important as the choice of the racquet frame. As a general rule, the harder you string the less power you get and the more control you have. The lower the tension, you gain more power but also lose control.
To show you the effects different string tensions and diameters can have on your racket’s performance take a look at the following chart.
The “string tension” of a racket is expressed in pounds or kgs. This indicates the pressure under which the strings are secured to the frame. The string tension affects a racquet’s playing characteristics, such as the “feel” of the ball, control over the ball, as well as maximizing the power.
All rackets come with recommended string tensions, most of which lie between 50 to 70 pounds for Tennis and between 25 and 34 pounds for Squash.
A loosely strung racket will usually have a larger sweet spot. A tighter string job will help make delicate shots with more finesse and give more control.
An extremely tightly strung racket cuts down on a player’s feel on the ball, but can give the player excellent control if swung hard enough, with a smooth stroke. Such tension may make delicate shots more difficult, but makes play more constant
It is advised by many professional stringers to string your racket with the lowest tension possible while still being able to maintain control of the ball. Beginning players trying to find their tension should start in the middle of the recommended tension range and adjust the tension from there to meet their needs.
The recommended tension is usually printed on the racket. With a lower tension the racket will have more power and less control; with a higher tension, it will have less power and more control.
