John Isner’s Tennis Racket

Isner is one of the greatest servers of all time, and a lot of that comes down to his height. He is one of the most powerful players in the world and there’s a lot of tennis fans wondering what racket he plays with.

In this post, I will go through Isner’s racquet and the string setup that he currently uses.

What Racket Does Isner Use?

John Isner plays with the Prince Textreme Beast 100. It’s a very control-oriented racket that allows for a lot of power. Perfect for Isner’s game with the big sweet spot and enough spin-potential for an effective kick serve.

It’s quite heavy, which works fine for a big guy like Isner, but it’s definitely not a racket that will work for anyone.

John Isner Racket Specs

Most of Isner’s overall game is about controlled power, and his racket setup reflects just that.

Here are Isner’s racket specs

  • Head size: 100 sq. in. / 645 sq. cm.
  • Length: 27.4 in. / 69.6 cm.
  • Strung weight: 12.2 oz. / 346 g
  • Strung balance: 331 mm
  • Stiffness: 59
  • Grip type: Prince Duratec + Tourna Overgrip
  • String pattern: 16 Mains / 19 Crosses

Isner strings his racket with Tecnifibre Red Code, but he switches his strings setup quite regularly. It’s not unusual for him to switch string setup during a tournament.

If something doesn’t feel right with his serve, he will change it after the game, and sometimes, he even has additional rackets in his bag with different string setups. With that said, the Tecnifibre Red Code is what he uses in most matches.

Can You Buy Isner’s Racket?

Isner’s racket is available to buy for his fans. It’s not a racket that’s available in every local tennis store, but it’s not hard to find it online.

It’s not the most beginner-friendly racket, but for the right player, it can be extremely beneficial. It seems to be working great for Isner.
