The world's fastest serve in tennis is a record often sought after and admired in the sport. Here's a breakdown of key aspects related to this impressive feat:
Current Record Holder
The official record for the fastest serve in men's tennis is held by Sam Groth. He achieved a serve of 163.4 mph (263.1 km/h) at the 2012 Busan Challenger event.
Key Factors Influencing Serve Speed
- Technique: Proper technique, including the kinetic chain movement, maximizes power transfer from the legs to the arm and racket.
- Strength and Conditioning: Core strength, leg power, and shoulder stability contribute significantly to generating serve velocity.
- Racket and Strings: The type of racket and string tension can influence the ball's speed and trajectory.
- Height: Taller players often have an advantage due to a higher contact point, allowing for a steeper angle and more downward force.
Other Notable Fast Servers
Several other players have recorded exceptionally fast serves throughout their careers. Some notable mentions include:

- John Isner: Known for his powerful serve, he has consistently ranked among the fastest servers on the ATP tour.
- Ivo Karlovic: Another tall player with a formidable serve, holding records for aces in a match and career.
- Milos Raonic: Consistently delivers serves at high speeds, making him a tough opponent.
Women's Fastest Serve
In women's tennis, the fastest serve recorded is 129 mph (207.6 km/h) by Georgina García Pérez in 2018 during a qualifying round at the Hungarian Ladies Open.
