How Many Sets Are There in Tennis? A Complete Guide
On this page5
In professional tennis, matches are either best-of-three sets or best-of-five sets. Best-of-three is standard for most events — win 2 sets to win the match. Best-of-five is used for men’s singles at Grand Slams — win 3 sets. Women’s singles everywhere uses best-of-three.
The Set Formats at a Glance
| Tournament / Event | Men’s Singles | Women’s Singles |
|---|---|---|
| Grand Slams (AO, FO, Wimbledon, USO) | Best of 5 | Best of 3 |
| ATP Tour (Masters 1000, 500, 250) | Best of 3 | — |
| WTA Tour events | — | Best of 3 |

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, most 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. Since 2022, all four majors have used the same rule: a 10-point match tiebreak when the deciding set reaches 6-6.
| Grand Slam | Final Set Tiebreak Rule (current) |
|---|---|
| Australian Open | 10-point tiebreak at 6-6 |
| French Open | 10-point tiebreak at 6-6 |
| Wimbledon | 10-point tiebreak at 6-6 |
| US Open | 10-point tiebreak at 6-6 |
This “match tiebreak” is first to 10 points, win by 2. It replaced a patchwork of earlier rules, including Wimbledon’s old tiebreak at 12-12 and the French Open’s advantage sets, after the Grand Slam Board standardised the format in 2022.
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.
