## Overview
Before the Open Era began in 1968, and for years afterward, players were ranked by their national associations and by a select group of authoritative tennis journalists, who did not always agree. The WTA applied mathematical formulas to singles in 1975 and added a doubles ranking on September 10, 1984.[1](https://www.wtatennis.com/news/4395021/wta-marks-50th-anniversary-of-pif-wta-rankings) The November 3, 1975 release was the first WTA computerized ranking, listing 135 players with Evert at the top.[1](https://www.wtatennis.com/news/4395021/wta-marks-50th-anniversary-of-pif-wta-rankings) Evert held the top spot for 138 of the next 140 weeks and 260 career weeks overall, with her final week as No. 1 coming in November 1985.[5](https://www.tennis.com/news/articles/on-this-day-in-1975-chris-evert-became-the-first-wta-no-1)
Because pre-1975 "world No. 1" designations were subjective lists rather than computed rankings, claims about players ranked No. 1 before that date belong to a different, unofficial tradition than the 30 women who have held the official WTA computer ranking.[1](https://www.wtatennis.com/news/4395021/wta-marks-50th-anniversary-of-pif-wta-rankings)
## How the ranking works
A player's WTA Singles Ranking is her total ranking points from 18 tournament results during a rolling 52-week period: the four Grand Slams, six WTA 1000 Mandatory combined or virtually combined tournaments, one WTA-only WTA 1000 Mandatory, and her best seven other results.[3](https://www.itftennis.com/media/13762/wta-2025-rankings-info.pdf) The WTA Finals counts as a 19th event, bringing the maximum counted tournaments to 19 for singles.[1](https://www.wtatennis.com/news/4395021/wta-marks-50th-anniversary-of-pif-wta-rankings)
**Point validity and drops.** Points stay valid for 52 weeks from the week a tournament is included in the totals, so a result remains in the totals for 52 weeks from the week it is included. [WTA Finals](https://www.edgepedia.org/wta-finals) points are the exception: they drop off on the Monday after the final WTA tournament before the following year's WTA Finals.[3](https://www.itftennis.com/media/13762/wta-2025-rankings-info.pdf)
**Mandatory zero-point counting.** A zero-point result at a Grand Slam, the WTA Finals, or a WTA 1000 Mandatory Commitment tournament must count on a player's ranking and remain there for 52 weeks even if she does not participate, subject to the Long-Term Injury Rule and the Special Ranking Rule.[3](https://www.itftennis.com/media/13762/wta-2025-rankings-info.pdf)
The rankings are computed and published weekly by the WTA from its Florida office and determine player acceptances and seeding for all tournaments; Year-End Rankings are processed immediately after the WTA Finals.[3](https://www.itftennis.com/media/13762/wta-2025-rankings-info.pdf)
## List of number 1 ranked players
Thirty players have held the No. 1 singles ranking since 1975, beginning with Evert and most recently Elena Rybakina, who first reached the top on 14 September 2026.[2](https://www.globaltennisnews.com/wta-world-no-1-list/) The count depends on the as-of date: 27 women had reached No. 1 as of 2020, 29 as of the close of the 2025 season, and 30 after Rybakina's debut.[5](https://www.tennis.com/news/articles/on-this-day-in-1975-chris-evert-became-the-first-wta-no-1) • [1](https://www.wtatennis.com/news/4395021/wta-marks-50th-anniversary-of-pif-wta-rankings) • [2](https://www.globaltennisnews.com/wta-world-no-1-list/) The ranking has changed hands 107 times according to the WTA's 50th-anniversary release, while the tour's record book timeline counts 101 changes since November 3, 1975; both figures come from official WTA publications.[1](https://www.wtatennis.com/news/4395021/wta-marks-50th-anniversary-of-pif-wta-rankings) • [4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf)
## By the numbers
**Total weeks at No. 1.** Stefanie Graf leads with 377 weeks, ahead of [Martina Navratilova](https://www.edgepedia.org/martina-navratilova) (332), [Serena Williams](https://www.edgepedia.org/serena-williams) (319), and Chris Evert (260).[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf) Graf's total spans 17 August 1987 to 30 March 1997, and her first 186 weeks were consecutive.[6](https://www.guinnessworldrecords.com/world-records/752755-most-weeks-ranked-no-1-in-singles-tennis-female)
**Consecutive weeks.** Graf's 186-week streak (Aug 17, 1987 – Mar 10, 1991) was equalled by Serena Williams (Feb 18, 2013 – Sep 12, 2016). Navratilova's best run was 156 weeks (Jun 14, 1982 – Jun 9, 1985), followed by [Ashleigh Barty](https://www.edgepedia.org/ashleigh-barty) at 114 (Sep 9, 2019 – Apr 3, 2022) and Evert at 113.[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf)
**Age records.** [Martina Hingis](https://www.edgepedia.org/martina-hingis) is the youngest to rank No. 1 in singles, at 16 years, 182 days on 31 March 1997; [Monica Seles](https://www.edgepedia.org/monica-seles) reached it at 17 years, 99 days (Mar 11, 1991) and [Tracy Austin](https://www.edgepedia.org/tracy-austin) at 17 years, 116 days (Apr 7, 1980).[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf) The oldest first-time No. 1 is Angelique Kerber, at 28 years, 238 days on 12 September 2016, and the oldest to hold the ranking is Serena Williams, at 35 years, 230 days on 15 May 2017.[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf)
**Stints and year-end finishes.** Evert and Navratilova share the record of nine separate stints as singles No. 1, and Navratilova has the most years finishing in the singles Top 10, with 20.[1](https://www.wtatennis.com/news/4395021/wta-marks-50th-anniversary-of-pif-wta-rankings) Year-end No. 1 is a separate distinction from weeks at the top: Graf leads with 8 year-end finishes (1987–90, 1993–96), ahead of Navratilova with 7 (1978–79, 1982–86), Serena Williams with 5 (2002, 2009, 2013–15), Evert with 5 (1975–77, 1980–81), and [Lindsay Davenport](https://www.edgepedia.org/lindsay-davenport) with 4.[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf) Sixteen of the 30 No. 1s have finished at least one season at year-end No. 1, meaning fourteen others reached the top without ever ending a year there; Evonne Goolagong's two weeks in 1976 are the fewest on the list.[2](https://www.globaltennisnews.com/wta-world-no-1-list/)
**Re-ranking the No. 1s.** A peer-reviewed study in the Journal of the Operational Research Society ranked 28 WTA No. 1 players from head-to-head results between 1973 and 2022, placing Serena Williams, Steffi Graf, and Martina Navratilova in the top three, followed by Martina Hingis, Kim Clijsters, and [Justine Henin](https://www.edgepedia.org/justine-henin).[7](https://www.tandfonline.com/doi/pdf/10.1080/01605682.2023.2180447)
## Eras of dominance
The ranking's history divides into long reigns by a small number of players. Evert set the pattern at the outset, holding No. 1 for 138 of the first 140 weeks.[5](https://www.tennis.com/news/articles/on-this-day-in-1975-chris-evert-became-the-first-wta-no-1) Navratilova then produced a 156-week unbroken run from June 1982 to June 1985 and finished seven years as year-end No. 1.[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf) Graf's era was the longest of all: 377 total weeks, including 186 consecutive from August 1987, and eight year-end finishes.[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf) • [6](https://www.guinnessworldrecords.com/world-records/752755-most-weeks-ranked-no-1-in-singles-tennis-female)
In the modern period, Serena Williams matched Graf's 186-week consecutive mark between February 2013 and September 2016 and finished five years at No. 1.[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf) More recently, Iga Swiatek accumulated 125 weeks at No. 1, including a first stint of 75 consecutive weeks, and finished 2022 and 2023 as year-end No. 1.[8](https://www.tennis365.com/wta-tour/wta-rankings-active-women-no-1-featuring-serena-swiatek-sabalenka-rybakina) • [4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf) [Aryna Sabalenka](https://www.edgepedia.org/aryna-sabalenka) followed with year-end No. 1 finishes in 2024 and 2025.[4](https://wtafiles.wtatennis.com/pdf/publications/2026MG/WTAMG26_WTARecordBook.pdf)
## Cross-tour weeks context
Graf's 377 weeks stood as the overall record across both the WTA and [ATP rankings](https://www.edgepedia.org/atp-rankings) until [Novak Djokovic](https://www.edgepedia.org/novak-djokovic) spent a 378th week at the top of the ATP rankings on 6 February 2023; as of 12 June 2023 Djokovic led with 388 weeks, ahead of Navratilova (332) and Serena Williams (319).[6](https://www.guinnessworldrecords.com/world-records/752755-most-weeks-ranked-no-1-in-singles-tennis-female)
## What has changed since 2023
Sabalenka's first stint at No. 1, in September 2023, lasted only eight weeks.[8](https://www.tennis365.com/wta-tour/wta-rankings-active-women-no-1-featuring-serena-swiatek-sabalenka-rybakina) Her second stint began on 21 October 2024 and lasted 99 consecutive weeks before Rybakina overtook her after the US Open, becoming the 30th world No. 1 and one of seven active players to have topped the rankings.[8](https://www.tennis365.com/wta-tour/wta-rankings-active-women-no-1-featuring-serena-swiatek-sabalenka-rybakina) Sabalenka secured the 2025 year-end No. 1 ranking for the second consecutive year.[1](https://www.wtatennis.com/news/4395021/wta-marks-50th-anniversary-of-pif-wta-rankings)
## Number 1 without a major title
The points system rewards consistent results across 18 counting tournaments over 52 weeks, so a player can accumulate more points than any Grand Slam champion without winning a major herself. Karolina Pliskova is the only active former No. 1 without a Grand Slam title; her best major results are runner-up finishes at the 2016 US Open and 2021 Wimbledon.[8](https://www.tennis365.com/wta-tour/wta-rankings-active-women-no-1-featuring-serena-swiatek-sabalenka-rybakina) Under the mandatory-event structure, zero-point results at Grand Slams and WTA 1000 Mandatory tournaments must count on a player's ranking for 52 weeks even if she does not participate.[3](https://www.itftennis.com/media/13762/wta-2025-rankings-info.pdf)
