Professional tennis players are very particular about their string setup. The type of string, gauge, and tension can affect power, control, spin, comfort, and feel.
In this guide, I’ve listed the reported strings and tensions used by leading ATP players, including Novak Djokovic, Carlos Alcaraz, Jannik Sinner, Alexander Zverev, and other well-known pros.
Most ATP players use polyester strings or hybrid setups combining polyester with natural gut. However, tensions vary widely depending on the player’s style, racket, surface, and conditions.
The average string tension used by the players listed below was just over 53 lbs, with Andy Murray having the highest string tension at 62 lbs and Cameron Norrie having the lowest string tension at 44 lbs.

What strings do professional tennis players use?
Most professional tennis players use either polyester strings or a hybrid setup that combines two different string types. Polyester strings are popular because they offer control, durability, and spin potential, while hybrid setups can add extra feel, comfort, or power.
Common strings used by ATP players include Babolat RPM Blast, Luxilon ALU Power, Head Hawk Touch, Yonex Poly Tour Pro, Wilson Natural Gut, and Babolat VS Touch Natural Gut.
On the ATP Tour, even small adjustments to string type or tension can have a significant impact on power, control, spin, and feel.
While most professional players use polyester strings for their durability and spin potential, the exact model and tension vary widely.
Some players string tight for maximum control, others go lower to generate extra power and comfort.
Many use hybrid setups, combining different strings in the mains and crosses to fine-tune performance.
In the table below, we’ll look at the strings and tensions used by players on the ATP Tour and former pros like Roger Federer and Rafael Nadal, highlighting common trends and individual preferences.
You’ll see how the pros balance control and spin at the highest level — and what you can learn from their setups for your own game.

FAQ
What string tension do professional tennis players use?
Most professional tennis players string their rackets somewhere between 45 lbs and 60 lbs, although this varies by player, racket, string type, surface, and conditions. Some players prefer lower tensions for more power and comfort, while others use higher tensions for extra control and a firmer feel.
What strings does Novak Djokovic use?
Novak Djokovic is widely reported to use a hybrid string setup, with Babolat VS Team Natural Gut in the mains and Luxilon ALU Power Rough in the crosses. His reported tension is usually in the mid-to-high 50 lbs range, although this can vary depending on the tournament and playing conditions.
What strings does Carlos Alcaraz use?
Carlos Alcaraz is reported to use Babolat RPM Blast in both the mains and crosses. RPM Blast is a polyester string known for its spin potential, control, and firm feel, which suits Alcaraz’s aggressive baseline game and heavy topspin.
What strings does Jannik Sinner use?
Jannik Sinner is reported to use Head Hawk Touch in both the mains and crosses. This full polyester setup gives him a controlled, firm response, which works well with his powerful, flat ball striking from the baseline.
Do pro tennis players use natural gut?
Yes, some professional tennis players use natural gut, usually as part of a hybrid setup. Natural gut is valued for its power, comfort, feel, and tension maintenance. Players such as Novak Djokovic, Andy Murray, Roger Federer, and Alexander Zverev have all been associated with natural gut/polyester hybrid setups.
What does lower string tension do?
Lower string tension usually gives a racket more power, comfort, and depth. The strings can stretch more on contact, which can make the racket feel livelier. However, lower tension may also reduce control for some players, especially if they swing very fast.
What does higher string tension do?
Higher string tension usually gives a firmer, more controlled feel. The ball comes off the strings with less trampoline effect, which can help some players control powerful shots. However, higher tension can feel less comfortable and may reduce easy power.
