The Women’s Tennis Association (WTA) runs the main professional tour for women’s tennis. It sets the tour calendar, oversees player rankings and works with tournaments around the world. If you follow the WTA, you’ll see familiar events such as Indian Wells and the Miami Open, as well as smaller tournaments where rising players build experience.
The association also has a history tied to a major shift in the sport: players organizing to gain a stronger voice and more equal treatment. Knowing how the WTA works makes it easier to understand tournament levels, ranking points and the race to qualify for the season-ending championships.
What Is the Women’s Tennis Association?
The WTA is the governing body for women’s professional tennis at tour level. It was founded in 1973 by Billie Jean King, who brought players together to create a more unified professional tour. The move built on earlier efforts by players to secure better conditions and recognition. In 1970, nine women—the group later known as the Original 9—signed contracts to play in a new professional circuit after challenging the gap between men’s and women’s prize money.
Today, the WTA supports and promotes professional women’s tennis, works with tournament organizers, and maintains the official WTA rankings. The tour includes players at different stages of their careers, from teenagers earning early ranking points to established champions competing for major titles.
The WTA is separate from the ATP, which oversees the main men’s professional tour. They sometimes work together on events, including tournaments that feature both men’s and women’s draws. Grand Slam tournaments, meanwhile, are run by their own governing bodies—not by the WTA or ATP—though results at those events count toward the tours’ rankings.
How the WTA Tour Is Organized
WTA tournaments are grouped into levels that generally reflect their ranking points, prize money and place on the calendar. A higher category usually offers more points, but a player’s decision about where to compete can also depend on travel, form, surface and the strength of the field.
| Tour level | What it means for players |
|---|---|
| WTA 1000 | Major tour events with large fields and high ranking-point rewards. |
| WTA 500 | Strong events that can help players make a significant ranking move. |
| WTA 250 | Tour-level tournaments that offer a route to titles and valuable points. |
| WTA 125 | Events that help players develop and earn points just below the main tour level. |
| WTA Finals | The season-ending championships for the top qualifying singles players and doubles teams. |
These categories do not include every important tournament. The four Grand Slams—Australian Open, French Open, Wimbledon and US Open—are the sport’s major championships. They offer substantial ranking points, but are organized independently from the WTA Tour.
Players also compete in ITF events, which sit below the main WTA Tour and can be an important first step in a professional career. For a newcomer, a strong run at an ITF tournament or a WTA 125 can help build a ranking and earn entry into higher-level events.
How WTA Rankings Work
The WTA singles ranking is based on a rolling 52-week period. In simple terms, points from a tournament count for about a year, then drop off as that event comes around again. A player who won a big title last season has points to defend; if she exits earlier this time, her ranking may fall even if she is still playing well.
Points depend on the event and how far a player advances. Winning a WTA 1000 or a Grand Slam usually brings a much larger reward than reaching the same round at a smaller tournament. Rankings also help determine entry into events and seedings, which can shape a player’s path through a draw.
The WTA Race is different from the rolling ranking. It tracks results within the current season and is used to identify players who qualify for the WTA Finals. That distinction explains why a player can be high in the rankings but have a different position in the Race: one reflects roughly a year of results, while the other focuses on the current season.
What the WTA Does for Players and Fans
The WTA’s work is broader than publishing rankings. It helps coordinate a global calendar, supports the commercial growth of women’s tennis, and works with tournaments on matters such as player services and competition standards. Its schedule also brings the tour to different surfaces and regions, giving fans a chance to follow players through hard-court, clay and grass seasons.
For players, the calendar presents practical choices. A clay-court specialist may plan a spring schedule around events that suit her movement and topspin-heavy game. A player returning from injury might choose fewer tournaments to manage her workload. And someone chasing a ranking goal may enter a smaller event where she has a better chance to reach the later rounds.
For fans, those choices can add context to a result. An early loss does not always mean a player is out of form; it may come after a demanding travel stretch or against an opponent whose game matches up well. Tennis is played one match at a time, but ranking and schedule decisions often stretch across a full season.

The Women’s Tennis Association is the central organization behind the women’s professional tour: its tournament structure, rankings and season-long competition. Its history began with players pushing for a stronger voice, and its modern calendar gives fans a year-round view of the sport.
