Two players in the history of tennis have won 24 Grand Slam singles titles. One of them played her last major in 1975, the other reached an Australian Open final in February 2026 at the age of 38. Ranking them against each other requires deciding what those 24 titles are actually worth, and most lists that put men and women together decline to make that call.
This one makes it. The best tennis players of all time are usually split into two rankings, which is defensible — the tours are separate, the formats differ, the history diverged in 1970. It also leaves the most-asked question in the sport unanswered.
What follows is a single ranking of 20 players, men and women, built on one set of criteria applied identically to both tours. The individual cases live elsewhere: our men’s top 10 and women’s top 10 argue each player in full. This page does the thing neither of them can — puts them on one scale.
How We Rank the Best Tennis Players of All Time
A ranking that only counts trophies collapses on contact with the evidence. Ken Rosewall was barred from the majors for 11 years. Margaret Court won 11 Australian titles against fields missing most of the world’s best. Monica Seles was stabbed on court at 19. Bill Tilden competed when reaching Australia meant a month at sea.
Seven criteria, weighted as follows. This is the methodology behind all three of our all-time tennis rankings, and it is applied identically to both tours.
| Criterion | Description | Weight |
|---|---|---|
| Major titles | Grand Slam singles titles, plus the professional majors won by players banned from the amateur game before 1968, adjusted for era and field depth | High |
| Era dominance | Weeks at world No. 1, year-end finishes, winning streaks | High |
| Strength of opposition | Quality of the field beaten; pre-1968 titles discounted | High |
| Peak level | How far clear of the field a player was at their best, judged on win rates and finals records | Medium |
| Surface versatility | Titles won on clay, grass and hard courts | Medium |
| Longevity | Years spent genuinely contending, including comebacks and late-career majors | Medium |
| Influence on the sport | Impact on the professional game beyond results | Low |
Figures come from ATP and WTA ranking records, Grand Slam archives, the International Tennis Hall of Fame and Bud Collins’ History of Tennis for pre-Open Era results, where world rankings were compiled by journalists rather than computers.
One note that matters more here than on either single-tour list. This ranking does not reorder either tour: the men appear in the same sequence as our men’s top 10, the women in the same sequence as our women’s top 10. The only judgement this page adds is how the two lists interleave — and that judgement is set out below the table.
Best Tennis Players of All Time: The Top 20, Men and Women
Ten men, ten women, counting down from twentieth.
| Rank | Player | Tour | Major titles | Time at world No. 1 |
|---|---|---|---|---|
| 20 | Venus Williams | Women’s | 7 | 11 weeks |
| 19 | Martina Hingis | Women’s | 5 | 209 weeks |
| 18 | Ivan Lendl | Men’s | 8 | 270 weeks |
| 17 | Justine Henin | Women’s | 7 | 117 weeks |
| 16 | Ken Rosewall | Men’s | 8 + 15 pro | Pre-rankings era |
| 15 | Bill Tilden | Men’s | 10 + 3 pro | 6 years, 1920–25 |
| 14 | Monica Seles | Women’s | 9 | 178 weeks |
| 13 | Pancho Gonzales | Men’s | 2 + 12 pro | 8 years, 1952–60 |
| 12 | Björn Borg | Men’s | 11 | 109 weeks |
| 11 | Pete Sampras | Men’s | 14 | 286 weeks |
| 10 | Billie Jean King | Women’s | 12 | Pre-rankings era |
| 9 | Chris Evert | Women’s | 18 | 260 weeks |
| 8 | Margaret Court | Women’s | 24 | Pre-rankings era |
| 7 | Rod Laver | Men’s | 11 + 8 pro | Pre-rankings era |
| 6 | Martina Navratilova | Women’s | 18 | 332 weeks |
| 5 | Roger Federer | Men’s | 20 | 310 weeks |
| 4 | Rafael Nadal | Men’s | 22 | 209 weeks |
| 3 | Steffi Graf | Women’s | 22 | 377 weeks |
| 2 | Serena Williams | Women’s | 23 | 319 weeks |
| 1 | Novak Djokovic | Men’s | 24 | 428 weeks |
Computer rankings began in 1973 for the men and 1975 for the women. Players whose careers predate them are judged on contemporary world No. 1 recognition instead: Tilden held it for six straight years, Gonzales for eight, and Court, King, Laver and Rosewall through periods when the top ranking was decided by journalists rather than points.
The Calls That Decide This List
Merging two rankings is not an averaging exercise. Four decisions determine everything above, and each of them is contestable.
Djokovic ahead of Court on the same major count. Both have 24. Thirteen of Court’s came before the Open Era began in 1968, eleven of them Australian titles won when the field routinely lacked the world’s best. Djokovic’s 24 came against full professional draws, alongside the records for weeks at No. 1, year-end finishes and Masters 1000 titles. Strength of opposition carries High weight, and it separates them decisively.
Serena second, ahead of Graf. The two heaviest criteria pull in opposite directions here. Graf leads on era dominance — 377 weeks at No. 1 is the women’s record and second only to Djokovic overall. Serena leads on strength of opposition, across a span half again as long: 18 years between her first major and her last, against Graf’s 12. Where a criterion tie has to break, this list breaks it toward the player who beat more, for longer, which puts Serena ahead by a margin thin enough to reverse under a different weighting.
Laver seventh, ahead of Court. The closest call on the page, and the one that most exposes the methodology. Both completed the calendar Grand Slam — Court in 1970, Laver in 1962 and 1969. Court’s Grand Slam total is more than double his official count. But the discount applied to each is different in kind: Court’s pre-Open majors are discounted because of who she beat, Laver’s missing majors were never available to him at all. Penalising an absence caused by a ban and a weakness caused by a thin draw at the same rate would be the easier call. It would also be the wrong one.
Navratilova sixth, ahead of Federer. Eighteen singles majors put her level with Evert and behind five of the ten men here once professional majors are counted. Every other criterion moves her up: 332 weeks at No. 1, the record nine Wimbledon singles titles, a 74-match streak that still stands, and 59 majors across all three disciplines, more than anyone else in the Open Era. This is the clearest case on the list of a player whose headline number is the least informative thing about her.
Who Is the Tennis GOAT, Male or Female?
Novak Djokovic, on the evidence available. He leads or matches the field on every measure that exists on both tours simultaneously: most major singles titles (24, level with Court), most weeks at world No. 1 (428, ahead of Graf’s 377), most year-end No. 1 finishes (eight, level with Graf), and a career Golden Slam completed in Paris in 2024.
No other player matches him on more than one of those. Court matches the major count and nothing else. Graf matches the year-end finishes and holds the only calendar Golden Slam ever completed, which remains the single most impressive season anyone has produced. Serena has the longest span of dominance against the deepest fields. Navratilova has the most majors across all disciplines in the Open Era.
Three caveats worth stating plainly, because the comparison has real limits.
- Format. Men play best of five at the majors, women best of three. Longer matches reward physical durability differently, and win percentages are not directly comparable across the two.
- Tour history. The women’s professional tour began in 1970 and computer rankings in 1975. The men’s amateur-professional split distorted major counts for two decades before 1968. Neither tour offers a clean continuous record.
- Field depth. Draw sizes, prize money and the number of countries producing elite players have all changed at different rates on the two tours, which makes strength of opposition the hardest criterion to apply across them.
Those caveats explain why the debate stays open. They do not change where the numbers currently point.

The Full Rankings, Tour by Tour

The men’s list is shaped by two eras that could not be less alike. The Big Three took almost every major between 2003 and 2023 and pushed the record totals somewhere the previous generation never approached. Before 1968, the opposite distortion applied: the best players in the world turned professional and were locked out of every major for a decade or more, which is why four of our top 10 have official Slam counts that badly understate them.

The women’s list carries a problem the men’s does not. Three of its top four competed in eras where one player could be reliably better than everyone else for a decade, and the current game has closed that window entirely. It also carries the sport’s widest era gap: the difference between winning an Australian title in 1963 and winning one in 2003 is greater on the women’s side than anywhere in men’s tennis.

Why This List May Not Change for a While
Lists like this normally have a shelf life. This one may not.
Everything the criteria above reward — weeks at No. 1, year-end finishes, majors stacked into a single decade — requires one player to be better than everyone else for long enough to accumulate them. That condition is disappearing. Wimbledon has produced ten different women’s champions in ten editions through 2026, and this year’s US Open reached its second round with none of Djokovic, Federer or Nadal in the draw, the first time a major has done so since Roland Garros in 2003.
Carlos Alcaraz is the exception worth watching, with seven majors at 23 and the youngest career Grand Slam in history. Jannik Sinner has five and the most reliable baseline in the sport. Iga Świątek has six and titles on every surface. Mirra Andreeva and Coco Gauff both have majors before turning 22.
None of them has held world No. 1 long enough to register on the criteria used here, and the depth of the current game makes that harder to fix than winning another major. A Djokovic-sized career needs a decade of clear water. Nobody currently playing has found any.
Frequently Asked Questions
Who is the best tennis player of all time?
Novak Djokovic. He leads on career totals across every measure that exists on both tours: 24 Grand Slam singles titles, 428 weeks at world No. 1 and eight year-end No. 1 finishes.
Who is the GOAT of tennis?
Djokovic holds the statistical case. Federer and Nadal supporters argue for peak level and head-to-head context, and Steffi Graf’s 1988 Golden Slam remains the single greatest season anyone has produced, which is why the debate stays unsettled.
Who is the best tennis player of all time, male or female?
Djokovic on our combined ranking, with Serena Williams second and Steffi Graf third. Margaret Court matches Djokovic on 24 majors but 13 came before the Open Era, which is why she ranks eighth here.
Who has won the most Grand Slam titles?
Margaret Court and Novak Djokovic, on 24 singles titles each. Serena Williams follows on 23, then Steffi Graf and Rafael Nadal on 22 and Roger Federer on 20.
Who has spent the most weeks at world No. 1?
Novak Djokovic, with 428. Steffi Graf is next on 377, then Martina Navratilova on 332, Serena Williams on 319 and Roger Federer on 310.
Can men’s and women’s tennis records be compared fairly?
Only partly. Majors, weeks at No. 1 and year-end finishes are directly comparable. Match records and win percentages are not, because the men play best of five at the majors and the women best of three.
How many players have completed the calendar Grand Slam in singles?
Five, on six occasions. Don Budge in 1938, Maureen Connolly in 1953, Rod Laver in 1962 and 1969, Margaret Court in 1970 and Steffi Graf in 1988. Graf’s was also a Golden Slam, the only one in able-bodied tennis.
Which active players could reach this list?
Carlos Alcaraz is closest, with seven majors at 23. Jannik Sinner has five, Iga Świątek six. None has yet held world No. 1 long enough to register on the criteria used here.
