When should you restring your tennis racket?

In short: three signals tell you it's time to restring — a broken string, gradual tension loss, or a loss of feel and control. How often you play remains the most decisive factor, more so than the calendar.

Signs it's time to restring

• The string has broken, even just one strand: the rest has aged the same way and often gives out shortly after.
• The strings are visibly frayed or discoloured where the ball makes contact.
• The strings shift easily and no longer snap back into place.
• The racket "sounds" duller, the ball feels less lively than before, even without a visible break.
• You feel more vibration or less control than usual.

A broken string vs. a string that's simply gone dead

A broken string is a clear, immediate signal: restring soon. A "dead" string bed without a break is subtler: actual tension drops gradually from the very first hours of play, well before any visible break — which is why many regular players restring without waiting for a string to snap.

The influence of string type

How fast a string loses tension depends heavily on its family. Monofilament loses tension faster than multifilament, despite better mechanical resistance to breaking. Natural gut holds tension longest of all, but stays more sensitive to humid conditions.

How often you play, and your profile

A recreational player who plays occasionally can usually keep the same string for several months without issue. A regular or competitive player will feel tension loss faster, simply because the string bed absorbs more impacts. A player who almost never breaks strings isn't immune to gradual tension loss either — it's a different kind of aging, but just as real.

A commonly cited rule of thumb

Among regular players, a rule of thumb often circulates: restring as many times a year as you play per week. It's a practical approximation, not a scientific rule — it doesn't account for string type or playing intensity, but it remains a reasonable starting point if you're unsure where to begin.

Storage and aging

A racket left in a hot car or a very humid environment can age faster even without being played. Natural gut is particularly sensitive to humidity; synthetic strings generally hold up better, but none are entirely immune to accelerated aging from poor storage.

Tracking your racket's condition

It's hard to remember exactly when you last restrung, especially with several rackets. That's exactly what Tension keeps track of for you — useful too for choosing which string to try next based on what you've already tested.
