A Grand Slam match can look identical on the scoreboard for several games, then the format creates a very different test. In singles, men play best-of-five sets and women play best-of-three. That one rule affects how many sets a player must win, how a match can swing, and how much time and stamina it may demand. Most other parts of the singles format are the same.
The main difference: how many sets you need to win
| Feature | Men’s singles | Women’s singles |
|---|---|---|
| Match format | Best of five sets | Best of three sets |
| Sets needed to win | Three | Two |
| Longest possible match by sets | Five sets | Three sets |
| Singles main draw | 128 players | 128 players |
| Matches needed to win the title | Seven | Seven |
At the Australian Open, French Open, Wimbledon and US Open, men’s singles matches are best-of-five throughout the main draw. Women’s singles matches are best-of-three. So a man must win three sets to take a match, while a woman must win two.
That does not mean men play more matches on the way to the trophy. Both singles champions usually need seven wins: one in each round from the first round through the final. A five-set match simply gives a man’s opponent more opportunity to recover from a slow start or turn the contest around.
How the scoring works
The basic scoring is the same in both draws. Players compete in games, games make up sets, and the first player to the required number of sets wins. A player generally needs six games to win a set, with a lead of at least two games. At 6–6, a tiebreak decides the set.
In a standard tiebreak, the first player to seven points wins, provided they lead by two. In the deciding set of a Grand Slam singles match, the tiebreak at 6–6 is a 10-point tiebreak: the first to 10, again with a two-point margin. This rule applies to men and women at all four majors.
For example, if a man has won two sets and the score in the third is 6–6, he needs to win that tiebreak to take the match. If a woman has won one set and the second reaches 6–6, she faces the same tiebreak format to finish the match. The number of sets differs; the set and tiebreak scoring does not.
What best-of-five changes on court
More room to recover
In best-of-five, losing the first set is a setback, not necessarily a crisis. A player can regroup, alter their tactics and still win three sets. That extra runway can reward players who adjust well during a match. It can also make a strong start less decisive than it would be in a shorter contest.
Best-of-three offers less time for a comeback. A player who drops the opening set may have to win the next two without another set to spare. That can make individual games feel especially important, though it does not guarantee a shorter match: long rallies, close sets and tiebreaks can stretch either format.
Endurance and tactical changes
A five-set match can test stamina, concentration and the ability to keep executing a plan after several hours. Players may need to manage their energy, vary their serve locations or change their positioning as an opponent adapts. In best-of-three, there is less time to wait for a pattern to pay off, so quick tactical decisions can matter greatly.
Neither format removes the need for fitness or mental toughness. Women’s matches can be physically demanding and dramatic, while a men’s match can be decided quickly if one player dominates. The format sets the possible length and comeback opportunities; it does not dictate the quality or intensity of the tennis.
Before the Grand Slams adopted a 10-point deciding-set tiebreak, the 2010 Wimbledon match between John Isner and Nicolas Mahut famously continued to 70–68 in its fifth set. Today, a deciding set cannot run on in that way: at 6–6, the tiebreak provides a finish. It is a useful reminder that match duration depends not only on best-of-three or best-of-five, but also on the tiebreak rules.
What is the same for men and women?
- The singles draw: Each major normally has a 128-player singles draw, including seeded players, direct entrants, qualifiers and wild cards.
- The route to the title: A champion generally wins seven matches in either singles draw.
- The court and basic rules: Men and women compete on the same courts, using the same court dimensions, net height, ball rules and game scoring.
- Prize money: The four Grand Slams award equal prize money to men and women in singles.
Equal prize money does not mean every match follows the same length format. It means the tournament pays the same amount for the corresponding stage of the men’s and women’s singles events. Scheduling also varies by tournament and day; it is not a simple rule that one draw always plays first.
What about doubles?
The best-of-five versus best-of-three distinction is mainly a singles comparison. At the Grand Slams, men’s, women’s and mixed doubles are generally played as best-of-three matches, with a 10-point match tiebreak used instead of a full third set. Event regulations can have details or exceptions, so the tournament’s published rules are the best reference for a particular draw.
That means it is worth checking which event someone is discussing. A men’s singles match at a Slam is best-of-five, but a men’s doubles match there is not automatically best-of-five. The same player might face different match formats in singles and doubles during the same tournament.
Frequently Asked Questions
Do women ever play best-of-five at a Grand Slam?
No. Women’s Grand Slam singles matches are best-of-three sets. Women’s doubles and mixed doubles also use their own doubles format, rather than the men’s singles best-of-five format.
Do men have to win more matches to win a Grand Slam?
No. The men’s and women’s singles champions generally each win seven matches. Men need to win more sets in each match, not play extra rounds.
Can a women’s match last longer than a men’s match?
Yes. A long three-set match can outlast a quick men’s match, and match duration depends on factors such as close games, rally length, and tiebreaks. Best-of-five allows more sets, but it does not guarantee a longer match every time.
Is the deciding-set tiebreak the same for men and women?
Yes. At 6–6 in the deciding set of Grand Slam singles, both men and women play a 10-point tiebreak, which must be won by two points.
Final Thoughts
The clearest answer is that men’s Grand Slam singles are best-of-five, while women’s singles are best-of-three. Both draws use the same basic scoring, normally have 128 players and require seven match wins to claim the title. Best-of-five gives players more sets to recover and puts a greater potential demand on stamina, but match length and drama depend on the players as much as the format.
