When to Restring Before the String Breaks
A string may look intact even after its launch angle and impact response have changed.
Player overview
Strings lose tension through time and impacts, and their surfaces wear. With polyester in particular, declining playability may appear well before breakage.
Measurement guide
- Look for a repeated change across several sessions in which balls launch unexpectedly high or land short.
- Check whether the main strings return to position and whether notches at the intersections have become deep.
- Use both the measurement trend and cumulative playing time, and replace the strings with enough lead time before a match.
Latest measurement
Choose replacement time from performance change, wear, and playing hours together rather than from the calendar alone.
