Court Dimensions

Both formats use the same physical court, but different lines define the boundaries:

Singles Court

  • Width: 5.18 m -- inner sidelines only. The tramlines are out.
  • Service depth: Full back boundary line. Long serves are viable.

Doubles Court

  • Width: 6.1 m -- outer sidelines. Tramlines are in play.
  • Service depth: Inner back line (76 cm shorter). Short serves dominate.

A shuttle landing on the tramline is out in singles but in for doubles. This is one of the most common rule errors among players who switch between formats.

Service Court Boundaries

Singles service box

Narrow (5.18 m) but deep -- the serve can reach the full back boundary. This makes the long serve a genuine threat. The service box is tall and slim.

Doubles service box

Wide (6.1 m) but short -- the serve must land before the doubles long service line, 76 cm inside the back boundary. The shorter box makes flick serves less effective because the receiver stands closer. The short serve dominates at higher levels.

Serving Rules

Both formats use the same diagonal serving rule and the same even/odd court system. The difference is what happens when a point is won.

Singles

  • Even score = right court. Odd score = left court.
  • No partner, so no court swap. The server simply moves to the appropriate court.

Doubles

  • Same even/odd court rule for the server.
  • Serving side scores: both partners swap courts, same player continues serving.
  • Serve changes hands: nobody moves. The player on the correct court becomes the new server.

Scoring

Scoring is identical in both formats:

  • Rally point scoring -- a point is scored on every rally regardless of who served.
  • First to 21 points wins a game, best of 3 games wins the match.
  • At 20-20 (deuce), must win by 2 points, with a 30-point cap.
  • Side change after each game and at 11 points in the deciding game.

Strategy Differences

Singles Strategy

  • Court coverage: One player covers the entire court. Fitness and movement efficiency are paramount.
  • Clears and lifts: High defensive clears are common, giving time to recover position.
  • Patience: Rallies tend to be longer. Forcing errors through positioning and fatigue is a legitimate strategy.

Doubles Strategy

  • Front-and-back: When attacking, one player covers the front court, the other the rear.
  • Side-by-side: When defending, partners split the court width evenly.
  • Speed: Rallies are faster and shorter. Flat drives and net kills dominate over high clears.
  • Short serve dominance: Because the service box is shorter, the short serve is standard. Flick serves are used sparingly as a surprise.

Frequently Asked Questions

Is singles or doubles harder in badminton?

Singles is more physically demanding -- one player covers the entire court. Doubles requires less court coverage per player but demands tighter coordination, faster reflexes, and precise communication. Neither is objectively harder; they require different skills.

Can you play singles rules on a doubles court?

No. You must use the correct court boundaries for each format. Singles uses the inner sidelines (5.18 m). Doubles uses the outer sidelines (6.1 m). The lines are painted on the same court, but the boundaries change based on the format.

What are the mixed doubles rules?

Mixed doubles follows the exact same rules as regular doubles -- same court, same service rotation, same scoring. The only differences are tactical, not regulatory. Pairs typically use a front-and-back formation when attacking.

Can the same player serve multiple times in a row in doubles?

Yes. As long as the serving side keeps winning rallies, the same player continues to serve, switching courts each time. The serve only passes to the opponents when the serving side loses a rally.
