Restring as many times per year as you play per week. Twice a week means at least twice a year — and that is a floor, not a target, because polyester goes dead long before it breaks.
The rule, and why it under-states the case
The “times per week equals times per year” rule has been club wisdom for decades and it is a reasonable minimum. It was also devised when most people played natural gut or synthetic gut, which degrade gradually and visibly.
Modern polyester does not behave that way. It loses tension and elasticity rapidly and then sits in the frame looking perfectly fine for months. A player who waits for a break on a poly bed may be playing on a dead string bed for most of the year.
Dead is worse than broken
A broken string is obvious and you replace it. A dead string bed is invisible, and it is quietly costing you two things.
Performance. The snapback that generates spin depends on the mains being able to move and return. As polyester stiffens and notches, that movement goes away. You lose spin first, then depth control.
Your arm. As strings lose elasticity they stiffen, so an old bed transmits more shock than a fresh one. If you have an elbow that occasionally grumbles, playing on six-month-old poly is one of the most reliable ways to wake it up. See strings for tennis elbow.
The four signs it is finished
1. Visible notching.Look where the mains cross the crosses. Deep grooves mean the mains can no longer slide and return — the string is mechanically done.
2. The mains stay out of place. Healthy strings spring back into alignment after a shot. If you are constantly straightening them by hand, snapback has gone.
3. The sound changes.A fresh bed is crisp. A dead one is dull and “clunky”. Most players notice this before they consciously register it.
4. Balls start landing long, then short. First the string loses control as tension drops, then it stiffens and loses power. If your depth has become unpredictable and your technique has not changed, suspect the string.
How long each type lasts
As playable life, not as time-until-breakage. Polyester:roughly 10–20 playing hours for most club players, and less if you hit heavy spin. Multifilament:degrades more gradually, often 20–30 hours, and usually breaks before it feels truly dead. Natural gut:the best tension maintenance of any string — it plays well for a long time, which is part of what you are paying for. Synthetic gut: goes dead quickly but is cheap enough that it does not matter.
A realistic schedule
| You play | Minimum (the old rule) | Better, on polyester |
|---|
| Once a week | Once a year | Twice a year |
| Twice a week | Twice a year | Three or four times a year |
| Three times a week | Three times a year | Every two months |
| Competitively, most days | Weekly or more | Weekly or more |
When a stringing machine pays for itself
Do the arithmetic rather than the vibe. Take your club's restring labour charge, multiply by how many jobs a year you actually need from the table above, and compare against a machine.
At typical US club rates, a Klippermatepays for itself in roughly ten jobs — which is one to two years for a committed club player, or a single season for a family with three players. The GAMMA Momentum 2costs more and adds six-point mounting and swivel clamps, which matters once you are stringing other people's frames.
The real cost is time: well over an hour for your first few, and 30–40 minutes once practised. If your time is worth more than the saving, use a stringer — but then actually use them on schedule.
Two frames, strung the same
If you play competitively, carrying a second racquet strung identically to the first is worth more than most gear upgrades. A string break mid-match on a single-frame setup means either borrowing something unfamiliar or retiring.
“Identically” matters: same string, same tension, same grip build-up, strung within a few days of each other. A spare frame that plays differently is barely better than no spare. A bag with thermal-lined compartments keeps both consistent between sessions.
Storage affects string life
Heat is the enemy. A racquet left in a hot car accelerates tension loss substantially, and repeated heat cycling is worse than one hot afternoon. A thermal-lined bag genuinely slows this down, which is the practical case for spending money on a bag rather than a rucksack.
Natural gut adds moisture to the list — it is damaged by damp and should never be left in a wet bag.
The cheapest performance advice on this site
If you take one thing from the whole strings hub: a mid-range racquet with a fresh string bed beats a premium racquet with a dead one, every time, and it is not close. Players spend hundreds on frames and then play eighteen months on the string it came with.
