Badminton Strings

Badminton strings are thin, high performing strings in the range of about 0.65 to 0.73 millimeters thickness. Thicker strings are more durable, but many players prefer the feel of thinner strings. String tension is normally in the range of 80 to 130 newtons (18 to 36 lbf). Recreational players generally string at lower tensions than professionals, typically between 18 and 25 lbf (110 N). Professionals string between about 25 and 36 lbf (160 N).

It is often argued that high string tensions improve control, whereas low string tensions increase power. The arguments for this generally rely on crude mechanical reasoning, such as claiming that a lower tension string bed is more bouncy and therefore provides more power. This is in fact incorrect, for a higher string tension can cause the shuttle to slide off the racket and hence make it harder to hit a shot accurately.

An alternative view suggests that the optimum tension for power depends on the player: the faster and more accurately a player can swing their racket, the higher the tension for maximum power. Neither view has been subjected to a rigorous mechanical analysis, nor is there clear evidence in favour of one or the other. The most effective way for a player to find a good string tension is to experiment. Playing at high string tensions can cause injury, depending on the player's ability: few amateur players can safely play above 30 lbf (130 N), and for most players even 25 lbf (110 N) is too high.
