The fastest tennis serve recognized by Guinness World Records belongs to Sam Groth, whose serve was measured at 263 km/h (163.4 mph) at the 2012 Busan Challenger. The official WTA and Guinness women’s record belongs to Sabine Lisicki at 210.8 km/h (131 mph), recorded at Stanford in 2014.
Those answers need context. Tennis does not have one universal historical speed database, and record lists often combine Grand Slams, tour events, Davis Cup, Challenger tournaments, qualifying and readings taken with different systems. A higher number is not automatically accepted by every governing body or record authority.
Fastest Tennis Serve Records at a Glance
| Record category | Player | Speed | Event and year | Recognition context |
|---|---|---|---|---|
| Guinness men’s record | Sam Groth | 263 km/h (163.4 mph) | Busan Challenger, 2012 | Recognized by Guinness World Records |
| WTA and Guinness women’s record | Sabine Lisicki | 210.8 km/h (131 mph) | Stanford, 2014 | Recorded with the tour’s recognized speed system |
| Higher unofficial women’s reading | Georgina Garcia Perez | 220 km/h (136.7 mph) | Hungarian Ladies Open qualifying, 2018 | Classified as unofficial because the standard tour measurement system was not used |
| Wimbledon record | Giovanni Mpetshi Perricard | 246 km/h (153 mph) | Wimbledon, 2025 | Fastest serve recorded in Wimbledon history |
| Women’s US Open record | Venus Williams and Alycia Parks | 207.6 km/h (129 mph) | US Open, 2007 and 2021 | Joint tournament record |
Speeds are shown using the figures published by the recognizing organization or tournament. Small conversion differences can appear when a speed measured in kilometres per hour is rounded into miles per hour, or the other way around.
Why Fastest-Serve Lists Disagree
Serve-speed rankings look simple, but the measurement context matters. A reading can be genuine without qualifying for the same record category as a speed recorded by another system.
Important differences include:
- Competition level: Tour main draws, Grand Slams, Davis Cup, Challengers and qualifying events do not always share one record policy.
- Measurement system: Radar placement, calibration and data processing can affect the displayed number.
- Official data retention: Not every tournament publishes or preserves a complete point-by-point speed archive.
- Recognition rules: A tour, tournament and independent record authority can classify the same reading differently.
- Rounding: A displayed whole number can produce slightly different conversions between mph and km/h.
This is why a responsible list should identify the record category instead of declaring every reported speed directly comparable.
Fastest Men’s Tennis Serves
Sam Groth: 263 km/h (163.4 mph)
Sam Groth holds the Guinness World Records title for the fastest male tennis serve. The Australian produced the 263 km/h serve on 9 May 2012 during a second-round ATP Challenger match against Uladzimir Ignatik in Busan, South Korea.
The serve was an ace, but Groth lost the match 6-4, 6-3. Guinness also records two other serves from the match at 255.7 km/h and 253.5 km/h, providing useful context for the peak reading.
The competition level should be stated because this was a Challenger event rather than an ATP Tour main draw. Guinness nevertheless recognizes Groth’s 263 km/h serve as the overall men’s record.
John Isner: 253 km/h (157.2 mph)
John Isner produced a 253 km/h serve against Bernard Tomic during the United States’ 2016 Davis Cup tie with Australia at Kooyong. The ITF’s official match report records the speed while describing the point in the third set.
It remains important to describe the category rather than call it an uncontested world record. Groth’s faster Challenger reading holds the Guinness title, while the Isner figure is an ITF-recorded Davis Cup reading.
Ivo Karlovic: 251 km/h (156 mph)
Ivo Karlovic was measured at 251 km/h during a 2011 Davis Cup doubles match between Croatia and Germany. The ITF confirmed it as a world record at the time, moving the mark beyond Andy Roddick’s previous 249.4 km/h reading.
Groth surpassed the number the following year, and Isner later recorded 253 km/h in Davis Cup competition. Karlovic’s serve remains one of the clearest examples of an officially acknowledged record within a major international team event.
Andy Roddick: 249.4 km/h (155 mph)
Andy Roddick reached 155 mph during a 2004 Davis Cup tie against Belarus. The ATP’s official biography highlights the 155 mph serve as one of the defining numbers behind his reputation as one of the leading servers of his era.
Roddick’s mark also shows that the highest serve-speed readings are not limited to players with the greatest height. Pace depends on coordinated leg drive, trunk rotation, upper-arm movement and forearm action as well as body dimensions.
Giovanni Mpetshi Perricard: 246 km/h (153 mph)
Giovanni Mpetshi Perricard set the Wimbledon serve-speed record against Taylor Fritz on 30 June 2025. His 246 km/h serve came in the opening game of their first-round match on Court No. 1 and exceeded Taylor Dent’s previous Wimbledon mark by 5 mph.
The serve did not end the point. Fritz managed to return it and eventually won the rally, a useful reminder that raw speed does not guarantee an ace.
Mpetshi Perricard also led the ATP Tour in average first-serve speed during the 2025 season at 216.3 km/h (134.4 mph). That average is a different achievement from a single record serve because it reflects repeated pace over many measured serves.

| Giovanni Mpetshi Perricard | 246 km/h (153 mph) | 2025 Wimbledon | Wimbledon tournament record |
This table is not presented as a universal all-time ranking. It contains notable readings with a clear institutional or contemporary record trail.
Fastest Women’s Tennis Serves
Sabine Lisicki: 210.8 km/h (131 mph)
Sabine Lisicki owns the WTA-recognized and Guinness women’s record. She hit the 131 mph serve against Ana Ivanovic in the first round of the 2014 Bank of the West Classic at Stanford.
The serve was recorded using the standard tour speed technology and landed in play. Ivanovic reached it but sent the return wide. Both the WTA and Guinness identify Lisicki as the official record holder.
Georgina Garcia Perez: 220 km/h (136.7 mph), Unofficial
Georgina Garcia Perez produced a higher displayed speed during qualifying for the 2018 Hungarian Ladies Open in Budapest. Guinness lists the 220 km/h serve as the fastest unofficial women’s reading.
It is not the official WTA record because the qualifying court did not use the standard SMT/IDS measurement system employed for tour main-draw records. The correct comparison is therefore not that one player’s number is true and the other is false. They belong to different recognition categories.
Brenda Schultz-McCarthy: 209.2 km/h (130 mph)
Brenda Schultz-McCarthy recorded a 130 mph serve during qualifying in Cincinnati in 2006. Guinness notes that the WTA did not recognize it as its tour record because it occurred outside the main draw.
The reading remains historically significant, but Lisicki’s main-draw 131 mph serve is the official WTA benchmark.
Venus Williams and Alycia Parks: 207.6 km/h (129 mph)
Venus Williams established a 129 mph women’s US Open record in 2007. Alycia Parks matched it during her first-round match against Olga Danilovic in 2021.
The US Open recognizes them as joint holders of its women’s tournament record. A tournament record is narrower than the world or WTA record, but it provides a clearly defined event-specific category.
Coco Gauff: 206 km/h (128 mph)
Coco Gauff reached 128 mph against Elena-Gabriela Ruse in the second round of the 2022 US Open. At the time, it was the second-fastest women’s serve recorded at the tournament, one mph behind the Williams and Parks mark.
Gauff’s example also shows why placement still matters. The serve was directed into the body and was effectively unreturnable, combining speed with a target that reduced the receiver’s reaction space.
Notable Women’s Serve-Speed Records
| Player | Recorded speed | Setting | Recognition status |
|---|---|---|---|
| Georgina Garcia Perez | 220 km/h (136.7 mph) | 2018 Budapest qualifying | Higher unofficial reading |
| Sabine Lisicki | 210.8 km/h (131 mph) | 2014 Stanford main draw | Official WTA and Guinness record |
| Brenda Schultz-McCarthy | 209.2 km/h (130 mph) | 2006 Cincinnati qualifying | Not recognized as the WTA main-draw record |
| Venus Williams | 207.6 km/h (129 mph) | 2007 US Open | Joint women’s US Open record |
| Alycia Parks | 207.6 km/h (129 mph) | 2021 US Open | Joint women’s US Open record |
| Coco Gauff | 206 km/h (128 mph) | 2022 US Open | Then second-fastest women’s US Open serve |
Record Speed vs Average Serve Speed
A player’s fastest single serve does not tell the full story. One serve can be hit at maximum pace on a favorable toss, while a high average requires the player to repeat speed across service games and matches. The serve-speed benchmarks by playing level put professional numbers in context.
First-serve percentage, placement, spin and the quality of the next shot also affect serving performance. A slightly slower serve placed close to a line can be harder to return than a faster ball directed into the receiver’s strike zone.
The second serve has a different job. Players normally trade some speed for spin and net clearance to reduce double faults. Trying to reproduce a first-serve record on every second serve would be tactically unsound.
How Is Serve Speed Measured?
Professional events use speed-measurement equipment positioned to track the ball shortly after it leaves the strings. The displayed figure represents early ball speed, before air resistance and contact with the court slow it down.
The exact setup matters. Radar angle, calibration, sampling method and where the system begins tracking can introduce differences. Official tournament systems provide a clearer record category than scattered historical readings, but not every venue has used identical equipment.
That limitation becomes more important when comparing records separated by decades or competition levels. It is reasonable to compare official tournament figures, but not to pretend that every number was created by one laboratory-standard test.
What Creates a Fast Tennis Serve?
Serve speed comes from a coordinated motion rather than the arm alone. The legs drive upward, the trunk rotates, the shoulder and forearm accelerate, and the racket reaches the ball at high speed near full extension.
Height and reach can help by creating a higher contact point and a more favorable path into the service box. They are advantages, not guarantees. Timing, mobility, strength, technique and the ability to transfer force through the full motion remain essential.
Players working on pace should first build a repeatable motion and reliable contact. The guide to how to serve in tennis explains the foundation, while the serve-speed guide focuses on generating more pace without simply swinging the arm harder.
Is the Fastest Serve Always the Best Serve?
No. A serve must land in the correct box, create a useful return and fit the score situation. The Mpetshi Perricard record at Wimbledon was returned, while many slower serves produce aces because of disguise or placement.
The most effective servers combine pace with wide, body and down-the-T locations. They also vary spin so the receiver cannot prepare for one trajectory. The ultimate tennis serving guide covers those tactical choices alongside the full motion.
For most players, improving the percentage of well-placed first serves and developing a dependable second serve will help more than chasing one maximum radar reading. A structured approach is covered in the guide to improving your tennis serve.
Final Verdict
Sam Groth owns the Guinness men’s record at 263 km/h, while Sabine Lisicki owns the official WTA and Guinness women’s record at 210.8 km/h. Georgina Garcia Perez has a higher 220 km/h women’s reading, but it remains officially classified as unofficial because of the measurement system used.
The most accurate way to discuss serve records is by category. Guinness records, tour-recognized speeds, qualifying readings and tournament records are all meaningful, but they should not be merged into one supposedly definitive list without explaining how each number was recorded and recognized.
Frequently Asked Questions
What is the fastest tennis serve ever recorded?
Guinness World Records recognizes Sam Groth’s 263 km/h (163.4 mph) serve from the 2012 Busan Challenger as the fastest male tennis serve.
Who has the fastest women’s tennis serve?
Sabine Lisicki holds the official WTA and Guinness record at 210.8 km/h (131 mph), recorded at Stanford in 2014.
Why is Georgina Garcia Perez’s 220 km/h serve unofficial?
The qualifying court in Budapest did not use the standard speed-measurement system used for WTA and ATP main-draw records. Guinness therefore classifies it as the fastest unofficial women’s serve rather than replacing Lisicki’s official record.
What is the fastest serve at Wimbledon?
Giovanni Mpetshi Perricard holds the Wimbledon record at 246 km/h (153 mph), hit against Taylor Fritz in the first round in 2025.
Does a record serve have to be an ace?
Not every tournament-specific record has been an ace. Mpetshi Perricard’s 153 mph Wimbledon serve was returned, and Fritz ultimately won the point.
Do taller players always serve faster?
No. Height can provide a higher contact point and useful leverage, but technique, timing, mobility and racket-head speed determine how effectively those physical advantages are used.
