ATP and WTA rankings both measure how well a tennis player has performed over a rolling year, but they are separate systems. They use different tournament calendars and can count results differently, so a player ranked No. 10 on the ATP Tour cannot be compared directly with the WTA No. 10 as if both places came from one shared list.
The main idea is the same: players earn points by reaching later rounds, and those points help determine their ranking, tournament entry and seeding. The details—especially which results count and how many points each round is worth—depend on the tour and event.
Here’s how ATP and WTA rankings work, where the systems match, and what fans should keep in mind when comparing players.
How ATP and WTA rankings work
Both tours use a rolling 52-week ranking system. A player earns ranking points at tournaments, and those points generally stay on the player’s record for about a year. When the same event comes around the following season, the old points come off and are replaced by the points earned there this time.
That’s why a player can win a tournament one year and still lose ranking points the next year—even after reaching the final again. For example, a champion who falls in the semifinals the following season will usually finish the event with fewer points than they are defending. Rankings are updated regularly, typically each week.
Players do not simply add every result from the past year. Each tour has rules for which tournament results count toward a singles ranking, including requirements tied to certain events for eligible players. The number and type of results included can depend on tour rules, participation and exemptions, so a player’s ranking total is not always a straightforward sum of every point they earned.

How players earn ranking points
Points are awarded according to the tournament and how far a player advances. A Grand Slam champion earns more points than a player who loses in the first round; the same principle applies at other tour events. A tournament’s level and draw also matter, and the points available at each stage are set out in the relevant tour’s rules.
The ATP and WTA use broadly similar tournament labels, such as 1000, 500 and 250 events. Those numbers describe the level of the tournament, not a guarantee that every round awards a set number of points. The full points table can differ between tours and event types, so check the official rules if you need an exact total.
Good results at lower-level events matter, too. A player who is still working toward the main tour may collect points at Challenger or ITF tournaments. Those points can help improve their ranking and open the door to stronger events. Qualifying and main-draw results may also count, depending on the event and rules.
Why the rankings are separate
The ATP and WTA are separate tours, with their own schedules, entry lists and ranking calculations. A player’s points are earned in that tour’s events, so the two lists measure performance among different groups of players. There is no combined ATP-WTA ranking that places every professional player in a single order.
This is important when reading tournament seedings. The men’s draw at a Grand Slam uses ATP rankings for its seeds; the women’s draw uses WTA rankings. A No. 1 seed is at the top of their respective tour ranking, not necessarily the top-ranked player across all tennis.
It also means that ranking numbers alone cannot tell you who is the “better” player between tours. They show where someone stands relative to competitors on the same tour. Comparing players across tours requires more context, such as their results, opponents and the competition they face.
Rankings versus the Race
Alongside the main rankings, both tours track a season-long Race. The Race starts fresh each calendar year and counts results from that season. It is useful for seeing who has been performing best lately, while the main ranking reflects points earned across the rolling 52-week period.
That difference can lead to two players switching places depending on which list you look at. A player who had a strong finish to the previous season may begin the new year with a high ranking, even if their current-season results have been modest. Another player may have a strong Race position after a great few months but still be lower in the main rankings because they are defending older points.
What rankings mean for players
A ranking has practical effects beyond bragging rights. It helps decide whether a player can enter a tournament directly, must play qualifying or needs a wildcard. It can also determine seeding, which affects a player’s place in the draw. Strong rankings make it easier to enter major events and can reduce the chance of facing another top seed early.
Rankings can also swing quickly. A breakthrough run at a major tournament may lift a player sharply, while an injury or early losses during a stretch when they are defending many points can cause a fall. For that reason, a ranking is a useful snapshot of recent results—but it is not a perfect measure of current form, health or potential.
Frequently Asked Questions
Are ATP and WTA rankings calculated the same way?
They share the rolling-year idea and award points for tournament results, but their detailed rules, event requirements and points tables are not identical. Use the relevant tour’s ranking rules for exact calculations.
Can an ATP-ranked player appear on the WTA ranking list?
No. The ATP and WTA maintain separate rankings for their respective tours. There is no shared list that ranks men and women together.
Why can a player lose ranking points after a good result?
Points from the previous year’s event usually drop off when that event returns. If the player earns fewer points this time than they earned last time, their total can fall despite a strong run.
What is the difference between a ranking and the Race?
The ranking reflects a rolling period of roughly 52 weeks. The Race tracks results from the current calendar year, so it offers a more focused view of that season’s performance.
Final Thoughts
ATP and WTA rankings follow the same broad logic: earn points through tournament results, keep those points for a rolling year and defend them when events return. But each tour has its own rules and ranking list. Treat the ATP and WTA positions as measures of standing within their separate competitions, and use the Race when you want a clearer picture of form during the current season.
