Badminton scores tell you three things: who won the rally, how close the game is to ending, and which service court comes next. This guide covers standard singles and doubles as of 7 October 2026, with the scheduled 2027 change explained separately.
Points, games and matches
The standard match is best of three games: winning two wins the match. Every completed rally produces a point for its winner, regardless of who served. A game normally ends at 21, provided the winner leads by two.
At 20–20, play continues until a two-point gap appears. Thus 22–20 finishes a game, while 22–21 does not. There is a ceiling: at 29–29, the next point wins, making 30–29 a valid result. The game winner serves first in the next game. These basics appear in the BWF simplified rules.
Choosing the service court in singles
Use the server’s own score. Zero or an even number means the right service court; an odd number means the left. The receiver stands diagonally opposite. A server who wins the rally scores and serves again from the other court. A receiver who wins scores and becomes the server.
For example, a player serving at 8–5 uses the right court. Winning makes it 9–5, so the next serve comes from the left. See BWF Laws 9 and 10.
Keeping doubles service order straight
Doubles uses the serving pair’s score to choose right or left. When that pair wins a rally on its own serve, the same player serves again from the other service court. When the receiving pair wins, it gains both a point and service.
Players do not swap their service-court positions merely because they won service back. Identify the new serving pair’s score, then the player in the corresponding court. The BWF doubles service guide illustrates this sequence.
Reading the umpire’s score call
The umpire announces the server’s score first. Consequently, the spoken order can reverse when service changes, even though the scoreboard still lists the players in the same rows.
Imagine the server leads 12–9 and loses the rally. The opponent now has 10 points and the serve, so the next call puts 10 before 12. Listening for the service-change announcement helps connect the spoken score with the next server. This convention is set out in the BWF instructions for technical officials.
Intervals and replayed rallies
An interval of up to 60 seconds is allowed when the leading score reaches 11, with up to 120 seconds between games. In a third game, players change ends when a side reaches 11. If a let is called, that rally does not count and the same player serves again. See BWF Laws 8, 14 and 16.
What changes on 4 January 2027?
The published BWF 2027 laws retain best-of-three matches but reduce the normal game target to 15. At 14–14, a two-point lead is required; at 20–20, the next point wins. The third-game change of ends moves to eight points.
Those future targets should not be applied automatically to a match using the current 21-point system. Check the event’s stated format, especially for local competitions or approved alternative formats.
For a comparison with another racket sport, see our guide to reading tennis points, games and sets. Tennis uses a different scoring ladder, so its scoreboard should not be read like badminton’s rally-point total.
A tied badminton game also differs from a tennis tiebreak. Compare the point targets, two-point margin and serving sequence in our tennis tiebreak and match-tiebreak guide; badminton retains its own service-court and score-cap rules.
