Every Monday, the ATP and WTA publish new rankings, but the system behind those weekly lists confuses plenty of fans. Here’s a straightforward breakdown of how points are earned, and why players can drop in the standings without losing a match.
## The Rolling 52-Week Window
Unlike a season-long standings table, ATP and WTA rankings operate on a rolling 52-week basis. Points earned from a tournament stay on a player’s ranking for exactly one year, then fall off entirely, regardless of results elsewhere. This is why a player can lose ranking points purely by not matching a strong result from the previous year.
## How Points Are Awarded
– Grand Slams offer the most points, with champions earning significantly more than any other event level
– Masters 1000 and WTA 1000 events offer the next-highest point totals, followed by 500 and 250-level tournaments
– Points are awarded based on how far a player advances, so even a first-round Grand Slam loss earns more points than winning a small tournament
## Why the Race and the Ranking Differ
Fans sometimes confuse the ATP or WTA Race, which counts only points earned since January of the current year, with the full rankings, which span two calendar years. The Race determines qualification for the season-ending Finals events, while the full ranking determines seeding at tournaments like the US Open.
## Real-World Example
Carlos Alcaraz’s rise back to world No. 2 despite not playing since April happened partly because points from Alexander Zverev’s prior-year Canadian Open run expired, not because of anything Alcaraz did on court.

## Why It Matters for Fans
Understanding the points system makes tournament seeding, and the drama around who holds the world No. 1 ranking, far easier to follow, especially during Grand Slam season when small ranking shifts can significantly change a player’s draw.
