Mixed doubles at a Grand Slam pairs one woman and one man on each team. The four majors all have a mixed doubles event, but match formats, draw sizes and schedules can differ—and can change from one year to the next.
The basic tennis rules are familiar: teams use the doubles court, take turns serving and try to win two sets. The details that catch people out are the match tiebreak, no-ad scoring and the fact that there is no rule requiring a man to play against a man or a woman against a woman.
How mixed doubles works
A mixed doubles team has two players: one man and one woman. They compete against another team made up the same way. The full doubles court is in play, including the alleys along each side, and the team that wins two sets wins the match.
Mixed doubles follows the normal doubles rules for serving, scoring and court positions unless that tournament’s regulations set out a special format. Players do not have to hit shots to an opponent of the same gender. A man at the net can volley a woman’s shot, for example, and a woman can return a man’s serve.
Scoring and match format
In a traditional Grand Slam mixed doubles match, the first two sets are usually played to six games, with a team needing a two-game lead. At 6–6, a tiebreak is played. Many mixed doubles events use no-ad scoring, meaning the receiver chooses which side to receive on the deciding point at deuce. Win that point and you win the game; there is no second advantage point.
If the players split the first two sets, a 10-point match tiebreak often replaces a full third set. The first team to reach 10 points with a lead of at least two wins. So a score of 10–8 ends the match, while 9–9 does not.
These are common features, not a promise that every major will use an identical format in every edition. The US Open introduced a redesigned mixed doubles competition in 2025, with a shorter format and a schedule before the main singles draw. Always check the tournament’s rules for that year before assuming the usual set length or draw structure.
How serving and receiving work
Each player serves for a full service game, and teammates take turns serving. The team decides its serving order at the start of a set. For instance, Player A serves the first game, an opponent serves the second, Player B serves the third, and the other opponent serves the fourth. The order then continues through the set.
On return, each player covers one side of the court. The receiving team chooses who takes the first serve of a return game and who takes the second. Players generally keep those receiving sides for the rest of that set, then can change sides at the start of the next one.
What makes mixed doubles different tactically?
The rules do not assign a particular role to either player, but teams often look for ways to use both players’ strengths. A strong first serve can set up the partner at the net, while a sharp return can force a quick volley or create a chance to attack. Good teams communicate constantly about who will take a ball down the middle, where the server’s partner should stand and when to switch positions.
Serve placement matters more than raw speed alone. A serve aimed at the body can jam a returner, while a wide serve can open space for the net player to intercept. On return, keeping the ball low or directing it at the server’s feet makes an aggressive first volley harder.
One familiar mixed doubles tactic is poaching: the net player moves across to intercept a return aimed toward their partner. It is not restricted by gender. The key is timing and trust. If one player crosses too early, the opponents can hit into the open court; if the pair never poaches, the returners may settle into a comfortable pattern.
How the Grand Slam events differ
The Australian Open, French Open, Wimbledon and US Open each stage mixed doubles, but their schedules, entry rules, draw sizes and match formats are set by their own tournament regulations. Some editions use a traditional draw played during the main fortnight; others may use a revised or shortened event. A change at one major does not automatically apply to the other three.
At all four events, mixed doubles offers a separate Grand Slam title from the men’s and women’s singles and doubles championships. A player can enter more than one event, though juggling matches across singles, doubles and mixed doubles can make recovery and scheduling a real challenge.
Why watch mixed doubles?
Mixed doubles can be fast and tactical. With four players sharing the court, points often turn on positioning and split-second choices at the net. The format also gives fans a chance to see top singles players working with doubles specialists, whose anticipation and volley skills can shape a match.
When watching, pay attention to the return team’s formation and the server’s partner. If that partner stands close to the net, the returner may try a lob or a low shot past them. If they stand farther back, the returner may take a bigger swing. Those small adjustments can decide a game even when both teams are hitting cleanly.
Frequently Asked Questions
Do mixed doubles players have to hit to an opponent of the same gender?
No. There is no such rule. Any player can hit the ball to either opponent, and either opponent can return it.
Is mixed doubles played on a full-size doubles court?
Yes. The doubles alleys are in, just as they are in standard doubles.
How many sets are played in a Grand Slam mixed doubles match?
Most traditional formats are best of three sets. In many editions, if the teams split the first two, a 10-point match tiebreak replaces the third set. Check that year’s tournament rules, since formats can vary.
Can a player enter mixed doubles and singles at the same Grand Slam?
Yes, subject to the tournament’s entry and scheduling rules. Players who enter multiple events may need to manage a busy schedule and limited recovery time.
Final Thoughts
Mixed doubles uses the familiar teamwork of doubles, with one woman and one man on each side and no gender-based limits on who plays a shot. The core ideas are simple: understand the service rotation, watch for no-ad points and know whether a match uses a 10-point tiebreak. Since each major can adjust its event format, the tournament’s current rules are the best guide to the exact setup.
