String tension changes how a badminton racket plays as much as the racket itself. Too low and the shuttle feels uncontrolled; too high and you lose power, your clears land short and strings break more often. Use the calculator below to get a sensible tension range for your level and playing style. If you choose your racket, or type its maximum tension, the result will never go above what the frame is rated for.
How the Calculator Chooses a Tension
The calculator starts from typical ranges used by stringers and coaches for each level, then adjusts for what you want from your strings:
| Level | Typical range | Why |
|---|---|---|
| Beginner / casual | 18–22 lbs | A softer string bed launches the shuttle more easily and has a bigger sweet spot. |
| Intermediate club player | 22–25 lbs | Enough control for placement while still forgiving on off-centre hits. |
| Advanced / league player | 24–27 lbs | A firmer string bed rewards a fast, consistent swing with sharper shots. |
| Elite / tournament player | 26–29 lbs | Maximum control and feel for players who generate their own power. |
Choosing more power moves the range down by about 1 lb, and more control moves it up by about 1 lb. Finally, the range is capped at your racket’s maximum tension.
Lower vs Higher Tension
- Lower tension gives more trampoline effect, an easier route to depth on clears, a larger sweet spot and longer-lasting strings. The trade-off is less precise control on fast shots.
- Higher tension gives a crisper feel and more control, but the sweet spot shrinks and you need a faster swing to hit the shuttle deep. Strings and frames are also under more stress.
A common mistake is copying professional players’ tensions. Professionals string high because their swing speed is far above a club player’s. For most players, a tension that feels slightly “too soft” at first produces better results than one that is too tight.
Other Things That Affect Feel
String gauge
Thinner strings (around 0.65–0.66 mm) feel livelier and give more bite, but wear out faster. Thicker strings (around 0.70 mm) are more durable. At the same tension, a thin string usually feels slightly softer and more powerful. Our guide to the best badminton strings for power and control compares popular options.
Tension loss
Strings lose some tension in the first days after stringing and continue to loosen with play. If your racket has not been restrung for months, it is probably playing below the tension you asked for.
Your racket’s limit
The maximum tension is usually printed on the shaft or throat of the frame. Stringing above it can crack the frame and void the warranty, so the calculator always keeps within it.

Frequently Asked Questions
What tension do most club players use?
Most intermediate club players are comfortable somewhere between 22 and 25 lbs. Start in the middle of the range the calculator gives you and adjust by 1 lb at a time.
How do I convert lbs to kg?
Multiply by 0.4536. For example, 24 lbs is about 10.9 kg. The calculator shows both.
How often should I restring?
A common rule of thumb is to restring as many times a year as you play per week. If you play three times a week, restring about three times a year, even if the strings have not broken.
