Mixed Doubles Tennis: Rules, Strategy & How to Win

You signed up for a mixed doubles night with a partner you met twenty minutes ago. Your opponents are friendly, a bit sharper than you expected, and by the third game you have noticed the same thing happening over and over: the ball keeps finding one of you. You are not sure whether to apologise, protect your partner, or go for more, and nobody told you the etiquette.

Mixed doubles is one of the most popular forms of club tennis, partly because it is the easiest way to get a mixed group on court with a fair game. It is also easy to play badly, because the usual doubles advice hides a few extra questions. This guide covers how the rules work, how to position yourselves, how to share the court with a partner, and the habits that win matches at recreational level.

What mixed doubles is, and what it is not

Mixed doubles is ordinary doubles tennis played by two teams of two, each team made up of one man and one woman. There are no special rules for it in the sport’s rulebook; the same laws that cover men’s or women’s doubles apply. What changes is the tactical picture, because the two players on one side usually differ in power, reach or serve speed, and the game works best when the team plans around that.

It has a long history as a social game. The social benefits of mixed tennis were recognised in England in the late 19th century, and mixed doubles became a championship event at the US National Championships in 1892, at the French Championships in 1902 and at Wimbledon in 1913 (Wikipedia, “Mixed doubles”).

At club and social level, mixed doubles is not always the strict one-man-one-woman format. A session may “mix” levels, genders or both. This guide assumes the standard team of one man and one woman, but nearly every tactic applies to any doubles pair with different strengths.

The rules in plain English

The court

In doubles, the two side alleys are in play, so the court is wider than for singles. The doubles court is 36 feet (10.97 m) wide, against 27 feet (8.23 m) for singles. The service boxes, baseline and net height stay the same. For a beginner this means more court to cover, but also two players covering it, so the angles open up more than they close.

Serving order

Before the match, the toss or spin decides who chooses between serving, receiving or the side of the court. After that:

• Each team decides which partner serves first in its first service game. The other partner serves the team’s next service game, and the order stays the same for the rest of the set.
• Each team also decides which partner receives from the deuce court and which from the ad court, and that arrangement stays for the whole set.
• You may change either order at the start of the next set, but not within a set. The opposing team does not have to tell you in advance, but each side should know who is returning where before the game starts.

The most common error at social level is forgetting the order, especially after a tie-break. If you are not sure, stop and agree on it with your opponents before the next point, rather than argue about it later. The tie-break has its own order: serving alternates after the first point and then every two points, and players change ends after every six points.

Scoring

Standard scoring is points of 15, 30, 40 and game, with deuce and advantage at 40-40, then games and sets. Many clubs shorten matches in one of two ways:

• No-ad scoring: at deuce, one deciding point is played and the receiving team chooses which side it is returned from. In mixed doubles, the rules of tennis add a gender requirement: the man receives from the man and the woman from the woman, so the receiving team cannot swap in the other partner for that point.
• Match tie-break: a 10-point tie-break replaces the third set. The first team to reach 10 points, winning by at least two, takes the match.

At the top of the sport, formats differ by event and change from year to year. The 2026 US Open mixed doubles, for example, was played as best of three sets of four games, with no-ad scoring and a 10-point match tie-break in place of a third set; only the final used regular six-game sets (Punto de Break, August 2026). Check any tournament’s current regulations before you rely on its format.

If you are organising a social mixed night, pick one format and announce it at the start. Short matches mean more rotation and more players on court, which is usually what a social group wants.

Positions: where to stand

Doubles is a game of formations. These are the four you will see.

One up, one back (the standard)

The server’s partner stands at the net, and the server stays at the baseline. The returner’s partner often does the same. It is the default because it gives the serving team a volleyer at the net to close the point, and a baseline player to keep the ball in play.

Both up

When your team has the ball in front and you can attack, both players move to the net. This gives the opponents very little room to hit through you and forces them to lob or hit a difficult passing shot. It is the winning formation at the net, but it makes you vulnerable to a good lob.

Both back

Defensive. Useful when you are being attacked, and a lot of recreational players stay here too long. If you find yourselves both stuck at the baseline for most of every point, you are probably giving the opponents the net for free.

Australian and I-formation

In the Australian formation, the server and the net player both start on the same side of the court. This changes the opponents’ angles and forces the returner to hit down the line. The I-formation is a variant where the net player crouches in the middle, and both formations usually involve a signal between partners. They are more advanced and worth trying only once your basic doubles are secure.

Strategy that wins at club level

1. Play to the middle

The most reliable shot in doubles is the ball hit down the middle, between the two opponents. It reduces the angle your opponent has, it can cause confusion over who takes it, and it keeps the net low (the net is lowest in the centre). Make “middle” your default when you are not sure.

2. Do not target by gender, target by weakness

Many recreational mixed games turn into a pattern where one team aims every ball at one opponent, usually the woman, or “the weaker one”, whichever it is. It is a known tactic, and it is legal. It is also less effective than people think, because the targeted player often gets a lot of reps and settles in, and because you hit a lot of predictable balls into a single spot.

A better habit is to find the weakness of each opponent: a weak backhand return, a poor lob, a slow first step to the net, a double fault under pressure. Then target that, whoever it belongs to. And if you are the team being targeted, accept it early. Your partner should move toward the middle, take a bit more of the court, and stay calm.

3. Serve with placement, not just power

At social level, a controlled first serve into the corner often does more damage than a full-power flat serve that misses half the time. Aim for the body of the receiver or the “T” down the middle. Both limit the angle of the return and set up your partner at the net.

4. Get your first serve in

Doubles points are often decided in the first three shots: serve, return, the first volley. The more first serves you land, the more chances your net partner gets to attack. If your first serve is unreliable, slow it down and add spin: aim for placement, and keep it in.

5. Return low and crosscourt

The simplest return in doubles is crosscourt, low and over the net, to the server’s feet if they are coming in. It is a high percentage shot, and it is difficult to volley. As the returner, you can also try a lob over the net player when you want to push them back.

6. The net player should be active

A net partner who stands still is a spectator. A confident net player will:

• Move with the ball: if your partner hits crosscourt, you shift slightly toward the middle.
• “Poach” selectively: cut across to volley a return that you are sure you can reach. Agree beforehand who covers the side behind you.
• Stay low and keep the racket in front.
• Take a clear overhead with a call of “mine” and let the other player have the rest.

7. Talk, every point

The single biggest difference between a doubles team that wins and one that does not is communication. Agree on a few calls: “mine”, “yours”, “switch”, “stay” and “out”. Decide before the match who takes the middle ball, and who takes the lobs. A pair that calls the ball clearly wins more points than a pair with better strokes that does not.

Sharing the court as a pair

In mixed doubles the physical difference between partners can be real: a faster serve, a longer reach, a heavier forehand. The best teams do not ignore it, and do not make it awkward either.

• Agree on a shared plan before the match. Who covers the lob? Who takes the middle? Who is going to serve first? Five minutes in the warm-up saves a lot of confusion later.
• Let the better volleyer play the net more often, whoever they are, and let the better baseline player cover the deep balls.
• Do not hit the ball away from your partner out of politeness. If you take every ball you can reach, the team usually plays better.
• Do not steal your partner’s balls out of anxiety either. A partner who is constantly cut off stops moving.
• Be positive between points. A short “good try” does more for a partnership than a tactical lecture.

For social players, this last point matters most. The goal is a good game that people want to come back for, not a perfect scoreline.

Common mistakes

1. Standing in the same place as your partner. Both players on the same side of the court leaves the other side open.
2. Backing off when the ball is hit to your partner’s side. Move together, even when you are not hitting.
3. Lobbing too early. The lob is a great weapon against a net player who is crowding, but if you do it on every point the opponents will just wait for it.
4. Forgetting the serving order. Write it down, or have it called out at the start of each service game.
5. Hitting hard at the net player. At close range, the net player sees the ball quickly and will often volley it back at your feet. Aim for gaps, not bodies, unless you are sure of the target.

Finding people to play mixed doubles with

The practical problem with mixed doubles is that it needs four people at roughly the same level, which is harder to arrange than a two-person hit. If you are looking for regular games, a few routes work:

• Your local club’s social session. Many clubs run a weekly doubles evening. Ask at the front desk. Our club directory lists courts and clubs by city, and our Bangkok club directory covers the capital in detail.
• A level-matched session. Our guide to social tennis explains the formats, and our guide to tennis rating systems helps you describe your level honestly when you sign up.
• Open Play. Breakers runs Open Play: level-matched, drop-in social tennis sessions where you book a seat for your level and play with people at your level, no partner needed. It is live in Bangkok for now. You can see the next session and book a seat.

If you are new to the game, start with our beginner guide and then try a social doubles session. If you want something more competitive later, beginner tournaments in Bangkok covers how people move from social play to competing.

A quick plan for your next mixed doubles match

1. Agree the format (full sets, no-ad, match tie-break) and the serving order before the first point.
2. Pick a default: serve to the body or the T, return crosscourt, play down the middle.
3. Agree who takes the lobs and the middle balls.
4. Find each opponent’s weakness in the first four games, and use it.
5. Talk after every point, even if it is only one word.
6. Play to enjoy it. A good game with people you want to play again is the best result.
