Tennis: what string tension should I choose for my racquet?

A good choice of strings is not enough. You also need to find the correct tension so that the racquet is a true extension of your arm and physique. It should not, therefore, work against your physical capabilities and performance technique.

Here is a summary of the advantages and disadvantages of the most extreme tensions.  







Impact absorption




More difficult to control

Less precision

Risk of tendinous injuries

Less power

Less impact absorption

The variety of string structures makes it impossible to only talk about tension in one way. This is why we can only describe a range of tensions for different types of strings.

We recommend that you try several tensions within these ranges.  


Gut, Multifilament, Hybrid



(1kg less on the crosses recommended)


(1 to 2kg less on the crosses recommended)


- Do not tighten soft strings as this will affect their efficiency too much. Looser strings will allow you to play a more relaxed game, without having to use force and you will therefore have more power.

- Through playing, the strings will wear out, even if they don’t break. They lose their elasticity and their original properties.

- The gauge (or diameter) also plays a role in how the game feels. The thinner the gauge, the more power and impact absorption you will have. The thicker the gauge, the more resistance in the strings.

More information: On the professional circuit, the lowest possible tension is 9kg and the highest possible tension is 42kg! But the average is 24kg, for the most part on a monofilament.

Now you know everything about string tension. All that’s left to do is get your racquet strung or string it yourself. To do this, please watch our video which will explain how to string your racquet properly.

Power: the strings’ ability to release energy on impact.

Holding tension: the strings’ ability to store energy over time.

Lifespan (resistance): the amount of time a string will last before it breaks due to repetitive friction in the strings.

Comfort: the strings’ ability to generate a minimum amount of vibrations on impact.

Impact absorption: the strings’ ability to absorb the impact from the ball (slice, lift etc.)



The string: THE big question for any self-respecting tennis player. Often compared to the soul of the racket, the choice of string is one of the most difficult choices to make about your tennis equipment. Monofilament or Multi-filament ? Is natural gut really cat gut? Too rigid, too soft, too loose ... There are so many questions about these few metres of string that we decided to give you as many responses as possible.
