Tennis Serve Speed Records: Every All-Time Record Ranked

The serve is tennis's most powerful weapon, and modern technology has pushed speeds beyond 160 mph (257 km/h). From Sam Groth's 163.7 mph to dominant first-serve percentages from the Big Three, this guide covers every serve speed record in professional tennis.

At Grand Slams, the fastest serve belongs to Isner at 157.2 mph. Wimbledon's grass surface, with its low bounce and fast conditions, traditionally produces the most aces. The 2010 Isner-Mahut match (70-68 in the fifth set) produced a combined 216 aces, the most in any professional match.

In the WTA, the fastest serve was recorded by Georgina García Pérez at 136.7 mph (220.0 km/h) in 2018. Serena Williams consistently served above 125 mph throughout her career, using her powerful serve as a foundation for her 23 Grand Slam titles. Sabine Lisicki held the previous record at 131.0 mph.

Modern serve speeds are enhanced by improved racket technology, with frames weighing 300-340g providing optimal power-to-control ratios. String tension, typically 48-58 pounds for professionals, significantly affects ball velocity. Player height correlates strongly with serve speed — the average height of the top 20 servers is 6'4" (193 cm), providing a steeper serve angle and more leverage.
