Badminton Doubles Rules: Serve Rotation & Court Positions

Doubles is the most popular format of badminton worldwide, and the serve rotation system is the part that confuses players the most. This guide breaks down the official BWF doubles rules into clear, digestible steps so you always know where to stand and who serves next.

Court Layout for Doubles

The doubles court uses the full width of the badminton court (outer sidelines), making it 6.1 metres wide compared to the 5.18 metres used in singles. However, the service court is shorter in doubles:

Sidelines: The outer sideline is used (the wider court). This applies to both serves and rallies.
Service back line: The inner back line (doubles long service line) is used for serves. This line is 76 cm in from the back boundary line. A serve landing beyond this line is out.
During rallies: After the serve, the full court is in play -- including the area between the doubles long service line and the back boundary line.

The key distinction from singles: in doubles the serve must land in a shorter, wider box, but during rallies the entire court is fair game. Many new players forget that the back tramline area is only out of bounds for the serve, not for regular play.

Service Rotation System

The doubles service rotation is governed by one simple principle: the server's score determines which court they serve from. Here is the complete system:

Starting the Game

  1. 1The serving side chooses which of their two players will serve first. That player starts in the right service court (score is 0, which is even).
  2. 2The receiving side chooses which player will receive first. That player stands in the diagonally opposite service court (also the right court from their perspective).
  3. 3The serve goes diagonally from the right court to the right court (server's right to receiver's right).

When the Serving Side Wins a Rally

The serving side scores a point. The same player continues to serve, but switches to the other service court (because the score changed parity). The server's partner also switches courts. The receiving side does not change positions.

When the Receiving Side Wins a Rally

The receiving side scores a point and gains the serve. No players on either side change positions. The player on the receiving team who is in the correct court for the new score (even = right, odd = left) becomes the new server. This is the part that confuses most players -- neither team switches courts when the serve changes hands.

The Key Rule to Remember

Players on the serving side swap courts every time they score a point. Players never swap courts when the serve passes to them. When you gain the serve, stay where you are -- whoever is on the correct side for the score serves. If you were on the right and the score is even, you serve. If your partner was on the right, they serve.

Even/Odd Court Rule

This rule is universal across all badminton formats and is the anchor of the entire positioning system:

Even Score: Right Court

When the serving team's score is 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, or 20, the server serves from the right service court.

Odd Score: Left Court

When the serving team's score is 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, or 21, the server serves from the left service court.

A practical way to verify you are in the correct position: if you won the previous rally on your serve, you should have switched courts. If the serve just came to your team, neither you nor your partner should have moved.

Mixed Doubles Specifics

Mixed doubles follows the exact same service rotation rules as standard doubles. There are no gender-specific serving regulations. The only differences in mixed doubles are tactical, not rule-based:

  • The serving and receiving positions follow the same even/odd court rule regardless of gender.
  • Either player (male or female) can serve at any point when it is their team's turn, based on court position.
  • Common tactical formation: the female player covers the front court while the male player covers the rear. But this is a strategy choice, not a rule.
  • During the serve, both partners must be in their correct service courts. After the serve, they can move anywhere on their side.

In competitive mixed doubles, the front-and-back formation is dominant when the team is attacking. When defending, teams typically shift to a side-by-side formation. The transition between these formations is a core tactical element.

Common Confusion Points

Do both partners get to serve before the serve passes?

No. This is a common misconception from older badminton rules (pre-2006) and from games like table tennis. In current badminton doubles, when the serving side loses a rally, the serve passes directly to the opposing team. Only one player serves per "turn" -- there is no second server.

Who serves first after winning the serve back?

Whichever player happens to be in the correct service court for the current score. If your team's score is even, the player on the right serves. If odd, the player on the left serves. You do not get to choose.

Why do the same two players keep facing each other?

Because the receiving side never swaps courts when they win the serve. They stay in their existing positions. This means the player who was in the right court when the rally was won stays in the right court. Over time, this creates a pattern where two specific players tend to be diagonally opposite more often.

What if we realize we were in the wrong positions?

If the error is discovered before the next serve, the rally result stands and players correct their positions. If the error is not discovered (play continues), the new positions become the established positions. The score is never changed retroactively because of a positioning error.

Can I serve to a different receiver each time?

You always serve diagonally. Since you switch courts when you score consecutive points, your serve will alternate between the two opponents. You cannot choose which opponent to serve to -- it is determined by the court positions.

Frequently Asked Questions

How does serve rotation work in badminton doubles?

The server is determined by court position and score parity. Even score = serve from the right court, odd score = serve from the left. When the serving side scores, the same player serves again from the other court. When the receiving side wins, the serve passes to them and the player in the correct court for the new score serves.

Do you switch sides after every point in doubles?

Only the serving team switches sides, and only when they score a point. The receiving team never switches sides. When the serve changes from one team to the other, no players on either side switch positions.

What are the court dimensions for badminton doubles?

The doubles court is 13.4 metres long and 6.1 metres wide (using the outer sidelines). The service court uses the inner back line (doubles long service line), which is 76 cm from the back boundary. During rallies after the serve, the full court including the back tramline is in play.

Can you serve long in badminton doubles?

A doubles serve must land before the doubles long service line (the inner back line). Serving beyond this line is a fault. This is different from singles, where the serve can go all the way to the back boundary line. The shorter service court in doubles prevents the server from pushing the receiver too far back.

What is the difference between mixed doubles and regular doubles rules?

There is no difference in the rules. Mixed doubles follows the exact same service rotation, court boundaries, and scoring as same-gender doubles. The only differences are tactical -- mixed doubles teams typically use a front-and-back attacking formation rather than side-by-side.
