Walk into a badminton shop and someone will ask what tension you want your racquet strung at, as if you're supposed to know. Most beginners guess a number, nod, and never learn what it actually does. Here's the real explanation — and why the popular advice to "string tighter" is often wrong for the people who hear it.
What Tension Actually Changes
String tension is measured in pounds and describes how tightly the strings are pulled across the frame. Its effect comes down to a single idea: the trampoline effect.
- Lower tension (looser strings, roughly the low-to-mid 20s in pounds for many players) makes the string bed act like a trampoline. The shuttle sinks in and gets flung back with less effort. That means more power and a larger sweet spot — more forgiving on off-centre hits.
- Higher tension (tighter strings) reduces that trampoline. The string bed is stiffer, so it returns less energy on its own. But it gives more control and a crisper feel, because the shuttle leaves faster and more predictably — for players who can generate their own power.
The trade-off is the whole story: power and forgiveness at lower tension, control and precision at higher tension.
High tension doesn't add power. It removes the string's help, and hands the job of generating power back to your technique.
Why Beginners Should Usually String Lower
This is the myth worth busting. Advanced players use high tension because they already have the racquet-head speed to power the shuttle themselves, and they want the pinpoint control tight strings provide. A beginner has neither the technique nor the speed to exploit that — so at high tension they get all of the downsides (no power, tiny sweet spot, mishits everywhere) and none of the benefits.
A beginner is far better served by lower tension: the trampoline does some of the work, the sweet spot is bigger, and clearing the shuttle to the back of the court stops feeling like a struggle. As your technique develops and you start generating your own power, you gradually string tighter to trade that assistance for control.
The Racquet Matters Too
Strings live inside a frame, and the frame's balance shapes the feel just as much:
- Head-heavy racquets put mass behind the shuttle for more smash power, at the cost of manoeuvrability — favoured by attacking singles players.
- Head-light racquets are quick and easy to whip around, ideal for fast exchanges and defense — favoured in doubles.
- Even-balance racquets split the difference and are a sensible default for a player still finding their style.
Shaft flexibility follows the same logic. A more flexible shaft loads and springs back to help generate power with slower swings — friendlier for beginners. A stiffer shaft rewards fast, well-timed swings with control and repels power for advanced players.
A Sensible Starting Point
If you're new, don't over-think it. Choose an even-balance racquet with a medium-to-flexible shaft, and string it at the lower end of the recommended range printed on the frame. You'll get power, forgiveness, and a big sweet spot while you build technique — and you can climb the tension ladder later, when your swing is fast enough to deserve the control that tight strings give back. Chase the setup that fits the player you are, not the one on the poster.
