Grand Slam titles are the first thing anyone checks in a tennis record book, and the top of the list is a tie. Margaret Court won 24 major singles titles, most of them before professionals were allowed in. Novak Djokovic reached the same number at the 2023 US Open. Serena Williams stopped one short at 23, Steffi Graf and Rafael Nadal finished on 22, and Roger Federer on 20.

ScoreboardThe all-time tennis records, by category

All time vs Open Era

All-time tennis records and Open Era records

Short answerThe Open Era began in 1968, when the majors first let professionals play. Records are often split at that line, with Court’s 24 Grand Slams as the all-time mark and Serena Williams’ 23 the women’s Open Era record.

Before April 1968 the Grand Slam tournaments were open only to amateurs. The best players often turned professional and vanished from the majors for years, which is why Rod Laver won his first Calendar Grand Slam in 1962 as an amateur and his second in 1969 in the new Open Era, with professional seasons in between.

That break makes "all time" and "Open Era" two different leaderboards. Margaret Court won 13 of her 24 majors before 1968 and 11 after it, so her record is the women’s all-time mark; Serena Williams’ 23 is the most of the Open Era. Among men there is no split to argue about, because all 24 of Djokovic's titles came in the Open Era, and so did every title of Nadal and Federer. Roy Emerson's 12, all won as an amateur in the 1960s, show how different the old count was.

One record survives both eras untouched. Steffi Graf's 1988 Golden Slam was all four majors and the Olympic gold in the same year.

Weeks at No. 1

Most weeks at No. 1, men and women

Short answerNovak Djokovic has spent 428 weeks at No. 1, the ATP record; Roger Federer is next with 310. Steffi Graf holds the WTA record with 377 weeks, ahead of Martina Navratilova (332) and Serena Williams (319).

The rankings are a computer creation of the Open Era, so this is one record with no amateur asterisk. Djokovic kept returning to the top spot for more than a decade, which is how he passed Federer's 310. On the women's side Graf's 186 consecutive weeks, ending in March 1991, were later matched exactly by Serena Williams between 2013 and 2016.

The current generation has a long way to go. Jannik Sinner had 95 weeks at No. 1 by the ATP ranking of October 26, 2026, Carlos Alcaraz 66. In women's tennis, Elena Rybakina became the 30th woman and the first from Kazakhstan to reach No. 1 on September 14, 2026, taking over from Aryna Sabalenka, who had 107 weeks at the top. The current top 10 of both tours is on our players page.

Most titles

Most singles titles in tennis history

Short answerMartina Navratilova won 167 tour singles titles, the most of the Open Era; Chris Evert won 157. Among men, Jimmy Connors leads with 109, ahead of Roger Federer (103) and Novak Djokovic (102).

Grand Slams measure peaks; tour titles measure how long a player stayed near the top. Navratilova's 167 and Evert's 157 came out of the same era, and their rivalry is the reason two women sit so far ahead of every man on this list.

The men's record is the one still moving. Djokovic won his 102nd title at the China Open in Beijing in October 2026, which also made him the first man in the Open Era to win a tour title in 21 straight seasons. He is one behind Federer and seven behind Connors.

Youngest and oldest

The youngest and oldest Grand Slam champions

Short answerMartina Hingis is the youngest Grand Slam singles champion of the Open Era, at 16 years 3 months in 1997. Ken Rosewall is the oldest of the Open Era, at 37 years 62 days in 1972, and Serena Williams the oldest woman, at 35 years 124 days.

The youngest records come from one burst in the late 1980s and 1990s. Boris Becker won Wimbledon in 1985 at 17 years 7 months, Michael Chang the 1989 French Open at 17 years 109 days, and Hingis the 1997 Australian Open at 16. Carlos Alcaraz holds a different youth record. At 22 years 8 months he became the youngest man to win all four majors, completing the set at the 2026 Australian Open.

At the other end, Rosewall’s 1972 Australian Open title has stood for more than half a century. The full ranking, with every age on one chart, is on our page about the oldest Grand Slam winners.

Records at each major

Records at each Grand Slam

Short answerEach major has its own record holder: Rafael Nadal's 14 Roland Garros titles, Novak Djokovic's 10 in Melbourne, Martina Navratilova’s 9 at Wimbledon. The longest match ever played, 11 hours 5 minutes, was at Wimbledon in 2010.

The single-tournament records are some of the most lopsided in sport. Nadal's 14 titles at Roland Garros, Djokovic's 10 at the Australian Open and Margaret Court's 11 in Melbourne are all records at one event. At Wimbledon, Navratilova won nine singles titles and Federer eight; the full list is on who has won the most Wimbledon titles.

The marathon records belong to Wimbledon. John Isner and Nicolas Mahut played for 11 hours 5 minutes over three days in 2010, a first-round match that finished 70-68 in the fifth set. The record for the longest Grand Slam final, 5 hours 53 minutes, is the 2012 Australian Open final between Djokovic and Nadal.
