How Many Sets Are There in Tennis? A Complete Guide
Most professional tennis matches are best-of-three sets, meaning the first player to win two sets wins. Grand Slam men's singles use best-of-five, requiring three sets to win.

How a Set is Won
A set goes to the first player to reach 6 games, provided they lead by at least 2. Common scenarios:
- 6–0, 6–1, 6–2, 6–3, 6–4 — one player wins cleanly
- 7–5 — the trailing player won game 5 to force 5-5, then both won a game, making it 6-6… wait, no: 7–5 means the leader won game 12 without needing a tiebreak
- 7–6 — the set reached 6-6 and was decided by a tiebreak
A tiebreak is a mini-game played first to 7 points (win by 2). The player who wins it takes the set 7–6.
The Final-Set Exception
For many years, Grand Slams played the final set as an “advantage set” — no tiebreak, keep playing until someone leads by two games. This produced some historically long sets. All four majors have now moved to a final-set tiebreak, though the threshold differs:
| Grand Slam | Final Set Tiebreak Rule |
|---|---|
| Australian Open | Tiebreak at 6-6 (standard) |
| French Open | Tiebreak at 6-6 (standard) |
| Wimbledon | Super tiebreak at 12-12 |
| US Open | Tiebreak at 6-6 (standard) |
The “super tiebreak” (also called a match tiebreak) is first to 10 points, win by 2.
Doubles Sets
Doubles matches follow the same set format as singles for the number of sets. However, many professional doubles formats replace the final set with a match tiebreak (first to 10) to keep total match time manageable. Check tournament-specific rules for exact format.
Why the Difference Between Men and Women?
The best-of-five format for men at Grand Slams is a longstanding tradition dating back to the early professional era. The women’s tour standardised on best-of-three. Arguments exist on both sides — best-of-five rewards consistency and endurance, while best-of-three keeps scheduling and physical demands more predictable. No formal change is currently scheduled.
Quick summary: Most tennis matches use best-of-three sets (win 2). Men’s Grand Slam singles use best-of-five (win 3). Each set requires at least 6 games with a 2-game margin, and a tiebreak is played at 6-6 in most modern formats.
