Choosing the right tension is as important as the choice of the racket frame. As a general rule, the tighter your 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.
| String Tension | Power | Control | Durability | Feel | Comfort |
| Softer | more | less | more | more | more |
| Tighter | less | more | less | less | less |
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 racket’s playing characteristics, such as the “feel” of the ball, control over the ball, as well as maximising the power.
All rackets come with recommended string tensions, most of which lie between 50 to 60 pounds for Tennis, between 25 and 32 pounds for Squash and between 22 – 28 pounds for badminton.
At beginner level it is advised to string your racket in the middle of the recommended tension range and adjust the tension from there to meet your needs.
