If your tennis strings are breaking easily, there’s always a reason — and it’s usually fixable. The most common causes are using the wrong string type, choosing a thinner gauge, stringing at too high a tension, or generating heavy topspin that causes the strings to rub and notch against each other. Softer multifilament strings offer comfort but tend to break faster, while polyester strings are more durable for aggressive players who hit hard and play frequently. Higher string tension can also increase stress on the string bed, making breakage more likely, especially in the sweet spot. In many cases, frequent string breakage is simply a sign that you’re improving, swinging faster, and generating more pace and spin. As players get stronger and spend more time on court, they may also benefit from transitioning to a slightly heavier racket for added stability and durability. Choosing the right combination of string type, gauge, tension, and even racket weight can significantly extend string life and improve performance.
