The Basics: 52-Week Rolling Points

A tennis player's ranking is the sum of points they earned at sanctioned tournaments over the past 52 weeks. Points are awarded for reaching specific rounds — the bigger the tournament, the more points each round is worth.

Every Monday after a tournament concludes, two things happen simultaneously to every player who competed there:

  • They add the points they earned this week (whether 10 for a first-round loss or 2,000 for winning a Grand Slam)
  • They subtract the points they earned at the same tournament 52 weeks ago (which now "drop off" the rolling window)

This is why a player who reached the final of a tournament last year is "defending points" this year — they need to match that result to keep their ranking stable. Losing earlier means their ranking drops, even if they were playing well.

How Many Results Count

Neither tour counts every match a player has played. Each tour caps the number of results that count toward the ranking:

  • ATP — Best 19 results over the 52-week window. The mandatory events (Grand Slams + Masters 1000 + ATP Finals if qualified) always count; below those, the player's best 6 results from other tournaments count.
  • WTA — Best 16 results over the 52-week window. Mandatory Grand Slams + mandatory WTA 1000 events always count; below those, the player's best results from other tournaments count.

For deep details on each tour's exact point distribution, see ATP ranking points explained and WTA ranking points explained.

What Counts as a Sanctioned Tournament

Both tours run a tiered tournament schedule. Each tier awards points to the winner:

  • Grand Slams (Australian Open, Roland Garros, Wimbledon, US Open) — 2,000 points to the singles champion. Equal on both tours.
  • ATP Masters 1000 / WTA 1000 events — 1,000 points to the champion. The biggest non-Slam events on each tour.
  • ATP 500 / WTA 500 — 500 points to the champion. Mid-tier events.
  • ATP 250 / WTA 250 — 250 points. Smaller tour events.
  • ATP Finals / WTA Finals — Year-end championships for the top 8. Up to 1,500 points for an undefeated champion.
  • Challengers / ITF events — Lower-tier events used by developing players and those climbing back from injury. Smaller point values; results from these tournaments fill the lower slots in the best-N system.

Mandatory Events

Some tournaments are mandatory: top-ranked players must play them, and skipping (without an approved medical reason) counts as a zero-point result. This is one of the most common reasons a top player's ranking drops without them playing at all.

Mandatory events typically include:

  • All four Grand Slams (both tours)
  • The bulk of Masters 1000 / WTA 1000 events (with specific exemptions outlined by each tour each season)
  • The year-end Finals (for players who qualify)

Rankings vs Race: What's the Difference?

Both tours run two parallel standings at the same time:

  • Rankings (the famous No. 1, No. 2, etc.): a rolling 52-week snapshot. Determines seeding at every tournament. Always the published "world ranking" number.
  • Race (Race to Turin for ATP / Race to the WTA Finals for WTA): a calendar-year-only standings. Only counts points earned in the current season. Used to determine the 8 qualifiers for the year-end Finals.

The Race and the rankings usually align by the end of the year because the rolling 52-week window has rolled through most of the calendar year. But mid-season they can look very different — a player who had a great late-season run last year might rank No. 5 in the regular rankings but No. 15 in the Race in March.

Live Rankings vs Official Rankings

The "live ranking" is a real-time projection of where a player would rank if updated points were applied immediately, mid-tournament. The "official ranking" is the one published every Monday. These differ during tournament weeks — see our full explainer at live rankings vs official rankings for examples and how to read them.

Protected Rankings & Special Cases

Both tours offer a protected ranking mechanism for players who are absent due to injury, illness, or pregnancy:

  • Eligibility typically requires 6+ consecutive months out of competition.
  • The protected ranking is the player's average ranking during the first 3 months of their absence.
  • It can be used to enter a limited number of tournaments (typically 9 main draws + select Slams) for up to 12 months after returning.
  • The protected ranking is used only for entry into tournaments — it does NOT affect seeding or actual world ranking, which still reflects current points.

WTA additionally offers a Special Ranking for players returning from pregnancy, with similar mechanics but extended timelines reflecting the longer absence period.
