Tennis, one of the most-followed sports around the world, is not merely about thrilling rallies and iconic matches between some of the best players like Roger Federer, Novak Djokovic, Serena Williams and others. It is also governed through a complex ranking system that determines who all get into tournaments, who is seeded, and ultimately, who sits at the top of the game.
Notably, a points-based ranking structure is followed by both Association of Tennis Professionals (ATP) and Women’s Tennis Association (WTA) that has been carefully designed to measure consistency and success across a rolling 52‑week period. The points are accumulated by players based on their performances across multiple tournaments, with Grand Slams offering the highest rewards.
Tennis Ranking System: History
The origins of the modern version of tennis can be traced back to the mid-1800s. However, during that time there was no formalised ranking system in place, according to Olympics.com.
In 1950, multiple British newspapers began providing their own rankings, which included tennis journalist Lance Tingay’s annual list of top 10 tennis players.
A few decades later, the ATP was established as the world governing body for men’s tennis in 1972. This helped to put in place the formal computerised tennis rankings to further streamline tournament entry criteria. On August 23, 1973, the first-ever men’s singles rankings got published, with Ilie Năstase of Romania emerging as the maiden ATP men’s singles world No. 1. Nearly three years later, they came out with the first men’s doubles tennis rankings on March 1, 1976.
In 1973, the Women’s Tennis Association (WTA) was set up by Billie Jean King. The world governing body in women’s tennis also adopted a similar formula.
This means that the ATP Rankings grade men’s singles and doubles players, while the same is done for women’s singles and doubles via WTA rankings. As of now, there are no formalised rankings for mixed doubles in tennis.
Initially, the ranking system’s core remained focused on averaging all the players’ results. But since 1990, this has changed to the ‘best of’ system that forms the base of the ranking methodology now.
ATP Rankings For Men’s Singles, Doubles
These are based on the points that players earn by taking part in official ATP-certified men’s singles or doubles events. It gets counted over the preceding 52-week time frame. However, this does not mean that a player, who has taken part in more tournaments, will get an advantage. For this, they have a cap on the number of tournaments that get counted towards rankings.
Initially, the number was 14 events, but later got increased to 18 in 2000. At present, it is the best of 18 – and 19 when the player qualifies for the Tour Finals, according to The New York Times.

Tournaments remain categorised based on importance that is embodied by the prize money that they can win along with the ranking points they can earn.
Notably, the four Grand Slams deliver the maximum points, awarding 2000 to the winner and 1300 to the finalist. It goes down to 10 points for players who lose in the first round itself.
In ATP Tour Finals, a player or a pair get to earn a maximum of 1500 points if they win the tournament undefeated. This includes 500 for winning the final, 400 for semi-finals and 200 for each of three round-robin matches.
For ATP Masters 1000, the maximum points is 1000 and goes down to 10. Among the top ATP Masters 1000 tournaments include Indian Wells, Miami Open, Cincinnati Masters, Madrid Open, Italian Open and Canadian Open among others.
In ATP 500 and ATP 250, the maximum points are 100 and 50, respectively.
WTA Rankings For Women’s Singles, Doubles
In WTA Rankings, the calculation mechanism is similar to the ATP, including the 52-week rolling window. Here, the best 18 results are counted. It becomes 19 if the player qualifies for the Tour Finals.
To calculate the rankings, both the ATP as well as the WTA have four Grand Slams and six 1,000-level combined events. Apart from these 10 events, there are respective Tour Finals if players make it to that stage of the game.
In WTA ranking, the maximum points for Grand Slams are 2000, followed by 1300 to finalist, 780 to semi-finalists and 430 to quarter-finalists.
Players get to earn up to 1000 in WTA 1000, 500 in WTA 500, 250 in WTA 250 and 125 for WTA 125 events. For WTA Tour Finals, a player or a pair get to earn a maximum of 1500 points after they win the tournament undefeated.
Penalties When Players Miss Events
In ATP Tour, when a player misses out on a mandatory event without providing any valid injury or approved reason, then they receive a zero-point ranking penalty. Missing out on ATP Masters 1000 events can lead players to lose proportions of the ATP Tour’s Bonus Pool. Overall, this amounts to a larger amount depending on the number of events missed as well as the ranking of the player.
Similar is the case on the WTA Tour, where players are given zero-point rankings penalties when they miss out on a mandatory event without providing a valid injury or an approved reason.
Also, there are multiple rules that allow players to further mitigate points or financial penalties after conducting promotional work as well as other appearances at the tournament in which they are not taking part.
They get to lessen financial penalties on the ATP Tour, but not zero-pointers. On the other hand, players can do it to avoid zero-pointers on the WTA Tour.
