What tension should you choose for your tennis racket?
Higher tension favours control, lower tension favours power and comfort. Here's how to find the right tension for you.
In short: the higher the tension, the stiffer the string bed and the more control it offers; the lower the tension, the more it flexes and the more power and comfort it gives back. The range printed on your racket's frame by the manufacturer remains the best starting point.
What is string tension?
Tension refers to the force the string is pulled and set at on the frame, usually expressed in pounds (lbs) in the US and much of the English-speaking world, or kilograms (kg) in Europe — 1 lb is about 0.45 kg. The higher this force, the less the string deforms on impact.
The manufacturer's recommended range
Most rackets display a recommended tension range directly on the frame, near the handle — often somewhere around 50 to 60 lbs (roughly 22-27 kg) depending on the model, with some variation by string type. This range is the most reliable starting point: it reflects how the frame was designed to perform.
Higher tension: general tendencies
A tension towards the top of the range makes the string bed stiffer: the ball stays on the strings for less time, giving a more direct feel and generally more precision, at the cost of needing more effort to generate power.
Lower tension: general tendencies
A tension towards the bottom of the range makes the string bed more flexible: it deforms more on impact and returns more energy, making power easier to generate. The trade-off is less forgiving control if the tension is too low for your swing, and sometimes a slightly shorter string life.
A word of caution: no universal rule
There's no single "ideal" tension. It depends on your racket, your string, your swing, your level and how it feels to you. The guidance here reflects general tendencies to discuss with your stringer, not rules to follow to the letter.
The influence of string type
The string you choose changes how tension feels. See our comparison of monofilament vs. multifilament to understand this interaction better.
The influence of gauge and head size
A thinner gauge flexes a little more easily, which can give a sense of extra power at the same tension. See also our article on which gauge to choose.
Level, playing style and priorities
Guidance by player profile
| Profile | Priority | Starting point | Possible adjustment | Watch out for |
|---|---|---|---|---|
| Beginner | Comfort, easy power | Lower end of the manufacturer's range | Raise slightly if control is lacking | Avoid tension too low for consistent contact |
| Regular / intermediate player | Balance | Middle of the range | Adjust by 1-2 lbs based on feel | Note the tension used to compare setups |
| Competitive player / fast swing | Control | Upper end of the range | Lower slightly if the arm feels fatigued | Too-high tension increases vibration |
| Player looking for power | Power, comfort | Lower end of the range, softer string | Raise gradually if shots become imprecise | Power gaps can also come from the string itself |
Tension and arm comfort
Some players feel less vibration on impact with lower tension or a softer string. This isn't medical advice, though: for persistent pain, see a healthcare professional rather than looking for the answer in tension alone.
Tension fades over time
Tension drops gradually from the very first hours of play. See our article on when to restring to know when that loss becomes significant.
Fine-tuning your tension with your stringer
The best way to find your tension remains talking to a stringer: they know your racket, can recommend a suitable string, and can adjust tension slightly each time based on your feedback.
