String Tension: The Biggest Adjustment You're Not Making
Most club players buy a pre-strung racket and never touch the strings until one breaks — sometimes 18 months later. That's like driving a car without ever checking tire pressure. String tension affects power, control, feel, and durability. A $15 string job can transform a $60 racket into something that plays above its price; the wrong tension can make a $200 racket feel dead. Understanding tension is the cheapest performance upgrade in badminton. Pair your Yonex BG65 string ($14.99) with any of our Yonex Astrox 77 Play ($89.99), Yonex Muscle Power 22 ($64.99), or other rackets in our range.
How String Tension Works
String tension is measured in pounds (lbs) — the pulling force applied to each string during stringing. Higher tension creates a tighter string bed with less trampoline effect. Lower tension creates more pocket depth and rebound. The trade-off is straightforward:
- Low tension (18-22 lbs): More power, larger sweet spot, more forgiving on off-center hits. Common on beginner pre-strung rackets.
- Medium tension (23-26 lbs): Balanced power and control. The sweet spot for most club and intermediate players.
- High tension (27-30+ lbs): Maximum control and precision. Smaller sweet spot — demands clean technique. What advanced and professional players use.
What Tension Do the Pros Use?
Professional players string between 28-34 lbs. Kento Momota used 32 lbs on his Yonex Astrox 99. Viktor Axelsen strings at 33-34 lbs. But these players also restring after every session because high-tension strings break faster. For recreational players, 30+ lbs is usually counterproductive — you lose the power assistance that compensates for imperfect technique.
When to Restring Your Racket
Three signs your strings need replacement:
- Visible fraying: The outer coating wears through, exposing the inner core. This is your clearest signal — don't wait for breakage.
- Dead feel: Strings that have lost 20%+ of their original tension feel "mushy" on contact. The shuttle doesn't rebound crisply. If your clears are falling short with the same swing, check your tension.
- Time: Even unplayed rackets lose 0.5-1 lb of tension per month from material relaxation. A racket strung at 24 lbs six months ago may be playing at 20-21 lbs.
A good rule: restring as many times per year as you play per week. If you play twice a week, restring every 6 months. If you play 4+ times weekly, restring every 2-3 months.

Our Badminton String Selection
We stock the Yonex BG65 string ($14.99) — the most popular badminton string worldwide. It's the workhorse: durable enough for beginners learning to hit the sweet spot, with enough feel for intermediate players. A single packet strings one racket. If you're trying a new tension for the first time, BG65 is the safe starting point.
How to Choose Your Tension
Beginners (0-1 year): Start at 20-22 lbs. You need the larger sweet spot while developing consistency. As your contact point improves, increase by 1-2 lbs every few months.
Intermediates (1-3 years): 23-26 lbs. You can feel the difference between tensions now. Experiment within this range to find your preference — many players settle at 24-25 lbs as their "home" tension.
Advanced (3+ years): 27-30 lbs. You have clean technique and want maximum shuttle control. Above 28 lbs, consider restringing every 4-6 weeks since tension loss is more noticeable at high tensions.

FAQ
What string tension should a beginner use?
Beginners should string at 20-22 lbs. Lower tension creates a larger sweet spot and more power, which helps while developing consistent contact. Increase by 1-2 lbs every few months as technique improves.
How often should I restring my badminton racket?
Restring as many times per year as you play per week. Playing twice weekly means restringing every 6 months. Playing 4+ times weekly means restringing every 2-3 months. Replace immediately if you see fraying.
Does higher string tension give more power?
No, the opposite. Lower tension (18-22 lbs) produces more power through a trampoline effect. Higher tension (27+ lbs) produces more control at the cost of power. Advanced players generate their own power through technique.
What's the difference between Yonex BG65 and BG66?
BG65 is a 0.70mm multifilament string built for durability — ideal for club players. BG66 Ultimax is thinner (0.65mm) with more repulsion and a harder feel, but breaks faster. BG65 lasts longer; BG66 plays livelier.
Can I string a badminton racket myself?
Badminton stringing requires a specialized machine ($200-1000+) and practice. The pattern is more complex than tennis stringing — crossed strings weave through shared grommets. Most players use a pro shop; a typical string job costs $15-25 labor plus string cost.
Do strings lose tension in storage?
Yes. Unplayed rackets lose about 0.5-1 lb of tension per month from material relaxation. A racket strung at 24 lbs and stored for six months may play at 20-21 lbs. Heat accelerates this loss — don't store rackets in hot cars.
