The thickness of your strings can completely change how your racket feels. This guide breaks down squash string gauges—thin vs thick—and shows how each affects power, control, spin, and durability so you can choose the perfect fit for your game.
String gauge measures how thick a string is, usually in millimetres. In squash, gauges range roughly from 1.10 mm (thin) to 1.30 mm (thick).
Thinner strings feel lively and powerful, offering extra bite on the ball.
Thicker strings feel firmer and more controlled, with improved durability and tension retention.
Thinner strings stretch more and snap back faster, giving you a stronger rebound effect—like a trampoline. If you want easy power with less effort, go thinner. Thicker strings require more swing speed to generate the same pace but provide better stability.
Thicker strings maintain their tension longer and give a more predictable response. If you prioritize accuracy, placement, and consistency, thicker gauges provide that firmer feel under pressure.
Thinner strings “dig” into the ball better, helping generate more spin or slice. For players who use deception, touch, or angled drives, thinner gauges give that extra bite on the ball.
Thicker strings last longer and resist breakage, especially for hard hitters or frequent players. If you often snap strings or train multiple times a week, go thicker to reduce restringing costs.
Thinner strings offer a soft, springy sensation with lively feedback. Thicker strings feel solid and direct, which some players prefer for confidence on contact.
If you’re a power-focused hitter, go for thinner strings—between 1.10 mm and 1.17 mm. They give you added rebound and easy pace.
If you’re a control or tactical player, a thicker gauge between 1.25 mm and 1.30 mm will feel more stable and precise, especially on touch shots and defensive play.
If you’re an all-rounder, stick with a medium range between 1.18 mm and 1.24 mm. This balances comfort, feel, and durability.
Frequent string breakers should move toward 1.25 mm or thicker.
Junior or developing players benefit most from 1.20–1.25 mm for forgiveness and consistent tension.
Different string materials react differently depending on gauge:
Multifilament strings (like Tecnifibre 305 or Dynamix) are naturally powerful and soft, so you can use a slightly thicker gauge without losing feel.
Monofilament strings are stiffer and more durable, so thinner versions make them livelier.
Textured or rough strings enhance grip and bite, giving a “spin boost” even if you stay with a medium gauge.
Pro Tip:
Keep a record of your string setups—tension, gauge, and type. After a few restrings, you’ll know which combination keeps its feel longest.
String gauge and tension balance each other.
If you go thinner, add a touch of tension to regain control.
If you go thicker, lower tension slightly to restore liveliness.
Start with your current setup, then make small adjustments—just one or two pounds at a time—to fine-tune your feel.
You might need to change gauge if:
When unsure, move one step thicker. Control and durability are easier to manage than excessive liveliness.
The right string gauge depends entirely on your game. Thinner strings amplify speed and feel, while thicker ones reward control and consistency. There’s no “best” option—only what best fits your swing and habits.
At My-Squash.com, we carry every major string gauge—from ultra-thin performance filaments to durable, control-focused hybrids. Experiment, take notes, and you’ll quickly discover your perfect setup.
Q: What gauge do professional players use?
Most pros use between 1.18 mm and 1.25 mm, balancing feel, power, and durability.
Q: Do thinner strings break faster?
Yes. Thinner strings offer better feel but wear out quicker because they flex more on impact.
Q: What’s best for beginners?
A medium gauge (1.20–1.25 mm) is ideal—it’s forgiving, stable, and maintains tension longer while you refine technique.
