Play Stronger: Pick the Right Badminton String Gauge to improve your Game

You've probably stood in the pro shop, staring at reels of string labeled 0.66mm, 0.68mm, 0.70mm, wondering if those tiny differences actually matter. They do, and even more than you might think.

Changing the string gauge without careful consideration can compromise your chances of dominating the game. How the shuttle bites into the string bed, how long your racket stays strung, and even whether your clears reach the back line without extra effort, it all depends on the strings you choose.

The gauge you choose isn't just a technical spec. It's a decision about what kind of player you are or want to become. Let’s understand what each thickness actually does on the court.

What Is String Gauge?

String gauge is simply the measurement of how thick the badminton string is, expressed in millimeters. The thinner the string, the more the shuttle sinks into the string bed, creating fast rebound and crisp sensation. As the string gets thicker, the feel becomes more solid and supportive, often lasting longer under high tension and frequent play. Most modern strings fall between 0.61mm and 0.70mm, with each thickness catering to a different type of player.

1. Ultra-Thin Strings (0.61mm – 0.63mm)

These are the scalpels of badminton strings. Touch one, and you'll notice how fine it feels, often almost fragile. That thinness is exactly what makes the shuttle explode off your racket with startling speed.

Ultra-thin gauges are designed for players who want instant shuttle response and maximum repulsion. Because the string is so fine, it flexes quickly upon contact, sending the shuttle off the racket with minimal effort. This gauge is ideal for fast-paced attacking players who rely on wrist acceleration and quick point construction. The feel is incredibly sharp, making it easier to play tight net shots, deceptive slices, and fast defensive blocks.

However, the same thin profile that provides responsiveness also makes these strings less durable. They tend to snap faster, especially at high tensions or during mishits, so they are better suited for advanced players who restring often and have good technique.

Examples:

Players like Kevin Sanjaya Sukamuljo used the Yonex Aerosonic (0.61mm) with his Astrox 88S Pro racket. He also used the Yonex Aerobite (0.61mm cross) to enhance precision and shuttle hold in rallies.

Anders Antonsen uses the Victor VBS-63 with his Victor ARS-90K Metallic badminton racket for explosive attacks and excellent precision.

1. Yonex Aerosonic (0.61mm)
2. Nydhi NS620 (Repulsion) (0.62mm)
3. Ashaway ZyMax 62 Fire (0.62mm)
4. Victor VBS-63 (0.63mm)

These strings are perfect for speed-driven and control-focused players who value high repulsion power over durability.

2. All-Round Medium Gauge (0.64mm – 0.67mm)

This is the Goldilocks zone. Not too fragile, not too stiff, but just right for most players who want their strings to last through a few sessions. Strings in the 0.65mm range represent the ideal balance between explosiveness and longevity. They offer excellent repulsion, strong power, and precise control, without compromising durability. This gauge is highly versatile, making it the most common choice among intermediate and advanced players who want a dependable setup for both singles and doubles.

The feel of a 0.65mm string is crisp yet controlled, helping players generate effortless power during clears and smashes while still maintaining confidence at the net. It handles fast drives in doubles just as well as long rallies in singles. It is also a great starting point for players who are unsure which gauge suits them best.

If you're torn between gauges, start here. It's forgiving enough to grow with you.

Examples:

Attack-oriented professionals often choose this gauge for its blend of speed and control. Many competitive players in Asia rely on Yonex BG66 Ultimax (0.65mm) for its precision and powerful punch. Taufik Hidayat, the retired Indonesian player, preferred the Yonex BG66 Ultimax for its lightning-speed repulsion. Li Shi Feng, Huang Dong Ping, and Kim So Yeong also use the badminton string for the ultimate blend of control, durability, and power.

Yonex Exbolt 65 is the most popular choice for Chen Yu Fei and Aaron Chia. And, Victor VBS-66 Nano is well-liked by Tai Tzu Ying, Wang Tzu Wei, Hendra Setiawan, Lee Zii Jia, and Ashwini Ponnappa.

1. Ashaway Zymax 64 TX (0.64mm)
2. Yonex BG66 Ultimax (0.65mm)
3. Exbolt 65 (0.65mm)
4. Nydhi NS660 - Control (0.66mm)
5. Nydhi NS660 Power/Repulsion (0.66mm)
6. Victor VBS-66 Nano (0.66mm)
7. Ashaway ZyMax 66 Fire (0.66mm)

This gauge works well for almost everyone, offering the best mix of performance, comfort, and durability.

3. Durable Strings (0.68mm – 0.70mm)

These are the workhorses. Built for players who'd rather practice than restring.

At 0.70mm, the string feels noticeably firmer under your thumb. They are thicker, tougher, and less likely to give way when you catch the shuttle off-center. That extra diameter absorbs punishment.

Players who value reliability and long-lasting performance often gravitate toward thicker strings. Gauges around 0.70mm are built to withstand heavy hitting, repeated mishits, and extremely high tensions. While they do not offer the same sharp repulsion as thinner strings, they deliver a solid and stable feel, which is ideal for training sessions, beginners, and hard-hitting athletes who tend to break strings frequently.

Examples:

Although many top players use thin gauges for competitions, powerful athletes like Viktor Axelsen often rely on thicker, more supportive strings such as Yonex BG80 (0.68mm), especially at high tension levels, to maintain firmness during explosive smashes. An Se Young, Kunlavut Vitidsarn, Chou Tien Chen, Satwiksairaj Rankireddy, Chirag Shetty, Michelle Li and many top-rated athletes prefer the durable BG80 for heavy smashes.

1. Yonex BG80 (0.68mm)
2. Yonex BG65 (0.70mm)
3. Nydhi NS690 Durability (0.69mm)
4. Ashaway ZyMax 69 Fire (0.69mm)
5. Nydhi NS700 XT Durability (0.70mm)
6. Nydhi NS700 Pro Hard Feeling (0.70mm)
7. Victor VBS-70 (0.70mm)

These strings are ideal for beginners, frequent string breakers, or players who want dependable durability over delicate touch.

4. Hybrid String (Mix of Thick and Thin Gauges)

Want the best of both worlds? Hybrid setups combine two different gauges. Usually a thinner string on the crosses and a thicker string on the mains. It creates a blend of power, control, and durability.

This setup is becoming increasingly popular among advanced players who want the explosive feel of a thin string without sacrificing lifespan. By placing the thicker gauge on the mains, the overall durability improves, while the thinner cross-string provides sharper touch and higher repulsion. The result is a string bed that feels lively yet stable, making it ideal for players who enjoy a fast but controlled game.

It offers the “best of both worlds” and is a strong choice for competitive players looking for a customized performance edge.

Examples:

Many top players choose hybrid stringing to fine-tune their racket’s performance. Along with Kevin Sanjaya Sukamuljo, Carolina Marin, Kong Hee Yong, Lin Dan, and Kento Momota preferred the Yonex Aerobite hybrid string during their careers.

Dechapol Puavaranukroh and Sapsiree Taerattanachai are known to use Yonex Aerobite Boost for powerful smash and incredible spin.

Several major brands offer ready-made hybrid options or strings designed for hybrid pairing.

1. Yonex Aerobite (0.67mm mains + 0.61mm crosses)
2. Aerobite Boost (0.72mm mains + 0.61mm crosses)
3. Victor promotes hybrid combinations such as pairing VBS-70 mains with VBS-63 crosses for durability plus repulsion.
4. Ashaway Rogue Duo Hybrid ( 0.68 mains + 0.61 crosses)

How to Choose the Right Gauge for Your Style?

If your strengths lie in fast, attacking play, a 0.61mm string will give you the explosive repulsion and crisp feedback you need.

Players who want a well-rounded setup for both speed and stability will feel immediately comfortable with a 0.65mm string. It is the most adaptable gauge and suits almost every style.

Finally, if you're a beginner, a heavy hitter, or someone who wants their string job to last longer, then a 0.70mm string will deliver excellent durability and unbeatable value.

Ultimately, your ideal string gauge depends on your playing level, technique, and how often you are willing to restring. Just like professional athletes tailor their rackets to complement their strengths, choosing the right gauge will help you unlock more control, more power, and more confidence on the court.
