The Most Misunderstood Topic in Badminton
Walk into any pro shop in India and ask the stringer "what tension should I use?" Nine times out of ten, the answer will be either "24 lbs is standard" or "high tension is for pros only". Both are oversimplifications. Your ideal string tension depends on your skill level, swing speed, racket type, the strings themselves, and even the climate of your city.
This guide goes deep into what string tension actually does, what tensions Indian players should use at each skill level, which strings work best, and where to get restrung in major Indian cities.
What Does String Tension Actually Do?
String tension is measured in pounds (lbs) and refers to how tightly the strings are pulled across the racket frame. The relationship between tension and performance is counter-intuitive:
- Lower tension (20-23 lbs): The strings stretch more on contact, acting like a trampoline. The shuttle stays on the strings longer, creating a "spring" effect that adds power. The sweet spot is large.
- Medium tension (24-26 lbs): Balance of power and control. Strings flex enough to give power on off-centre hits but tight enough to give a clear feel of where the shuttle is going.
- High tension (27-30+ lbs): Strings barely flex. The shuttle leaves the strings almost instantly. Maximum control, but the sweet spot shrinks dramatically. Off-centre hits feel dead.
This is the opposite of what most beginners assume. Many think "high tension = power". In reality, high tension only delivers power if you have the swing speed to compress the strings yourself. Without that swing speed, high tension just makes shots feel weak and dead.
The Right Tension for Each Skill Level
Absolute Beginner (3-6 months of play)
Recommended: 20-22 lbs.
You need every bit of help to get the shuttle to the back of the court. Low tension provides a trampoline effect that compensates for slower swing speed. Stick with stock string at this level.
Improving Beginner (6-12 months)
Recommended: 22-23 lbs.
You can now generate some power on your own. Slightly higher tension gives you better placement without sacrificing too much power.
Intermediate Club Player
Recommended: 24-25 lbs.
This is the sweet spot for most adult Indian recreational players. Enough tension for control, enough flex for power.
Advanced Club / Tournament Player
Recommended: 26-27 lbs.
You have the swing speed to deliver power independently. Higher tension lets you place shots precisely.
State / National Level
Recommended: 28-30 lbs.
You need maximum control. Power comes from your kinetic chain, not the strings.
Top National / International
30-34 lbs.
PV Sindhu reportedly strings at 28-30 lbs depending on conditions. Lin Dan was famous for stringing at 32-33 lbs. Lakshya Sen strings around 28-29 lbs. These tensions require restringing every 2-4 matches because they cause string fatigue quickly.
String Type Matters As Much As Tension
The same tension feels completely different on different strings. The most popular strings in India in 2026:
Yonex BG-65 (~ Rs. 250 with labour)
The most popular all-round string in India. Excellent durability, balanced feel, available everywhere. Good for tensions 22-28 lbs.
Yonex BG-65 Titanium (~ Rs. 300)
Slightly more repulsion than standard BG-65. Good for intermediate players.
Yonex BG-66 Ultimax (~ Rs. 400)
Premium repulsion-focused string. Used by attacking players for extra smash power. Less durable than BG-65 — expect 8-15 hours of play before breakage.
Yonex BG-80 (~ Rs. 350)
Balanced power and durability. Popular among intermediate-to-advanced players.
Li-Ning No. 1 / No. 7 (~ Rs. 200-280)
Solid alternatives to Yonex strings, slightly cheaper. No. 7 is more durable; No. 1 has more power.
Apacs Z-Power 65 (~ Rs. 200)
Excellent budget option. Great for club players who break strings often.
Tension Recommendations by Racket Type
Your racket dictates safe tension limits. Stringing too tight on the wrong frame can deform or crack it.
- Aluminium frame (Cosco, basic Nivia): Maximum 22 lbs. Higher will warp the head shape over time.
- Hybrid (alu head, graphite shaft): Max 24 lbs.
- Entry full-graphite (Yonex Nanoray Light, Li-Ning Smash XP): 22-26 lbs.
- Mid-range graphite (Yonex Astrox Lite, Li-Ning Turbo X): 24-28 lbs.
- Premium graphite (Yonex Astrox 88D, Victor Thruster K): 26-30 lbs.
- Pro-level (Yonex Astrox 99 Pro, Li-Ning Aeronaut 9000): 28-34 lbs.
Always check the tension range printed on the racket frame near the throat. Stringing above the rated maximum voids warranty and risks frame damage.
Climate Effects in India
Indian cities have varied climates that affect string tension over time:
- Mumbai, Chennai, Kolkata (high humidity): Strings absorb moisture and lose tension faster. You may want to string 1 lb tighter than your target.
- Delhi (extreme summer/winter swings): Tension drops significantly when stored in heat. Restring more frequently.
- Bengaluru, Hyderabad (moderate climate): Strings hold tension longer. Standard recommendations apply.
- Pune, Nagpur (dry): Strings tend to feel slightly tighter than the labelled tension.
How Often to Restring?
The classic guideline: restring as many times per year as you play per week. Play 3 times a week? Restring 3 times a year. This is conservative for serious players.
Concrete signs you need restringing:
- Strings have visible notching where they cross
- Shots feel "dead" — no spring, no zip
- You can press the strings down with your finger and they don't bounce back
- You hear a different sound on contact (a thud instead of a crisp pop)

DIY Stringing — Worth It?
If you play 4+ times a week, a personal stringing machine pays for itself within a year. Entry machines like the Stringway Maestro start at Rs. 18,000 in India. Crank-style machines are much cheaper but less consistent. Most academy pros use electronic constant-pull machines that cost Rs. 60,000+.
For most club players, paying a professional Rs. 250-400 every 2-3 months is far simpler.
Common Tension Myths
- "Higher tension means more power": False. Power comes from string compression, which higher tension reduces.
- "Pros use 30+ lbs because it gives them an edge": Pros use it because they have the swing speed for it. For most players it would feel terrible.
- "Strings are strings, only tension matters": False. String type affects feel as much as tension.
- "You should restring only when strings break": By the time strings break, you've been playing with dead strings for weeks.
Quick Reference Table
- Beginner: 22 lbs, BG-65 or stock string
- Intermediate: 24-25 lbs, BG-65
- Advanced club: 26-27 lbs, BG-66 Ultimax or BG-80
- Tournament: 28-30 lbs, BG-66 Ultimax
- National+: 30+ lbs, premium strings
One Final Tip
If you have never experimented with tension, try this: get your next two restrings 2 lbs apart (say 24 and 26). Play with each for 2 weeks. You will quickly feel which one suits your game. Most players never do this experiment and stick with whatever the stringer chose.
