Badminton Score Counter
A badminton score counter keeps a rally-scored game: every rally wins a point, and the server's score decides the court, right when even and left when odd. This one also tracks doubles positions and ends each game correctly under both the 21-point laws and the BWF 3×15 system that starts on 4 January 2027.

Tap the side that won the rally, not the side that served. A or ← scores side A, L or → scores side B, Ctrl+Z undoes. In doubles, player 1 of each pair starts in the right court; swap before the first rally of a game if your pair has chosen otherwise.
This is a scorer for club, school and friendly games, not an official score sheet. In a sanctioned match the umpire’s sheet is the record, and the tournament prospectus decides which scoring system applies. The 3×15 rules here are the ones the Badminton World Federation announced when it adopted the system; if your league or county association switches on a different date, or keeps 21, pick the system it actually plays.
Adding one to a number is the easy part. The questions at the back of the court are who serves, from which side, and whether that point just ended the game — and from January 2027 the answer to the last one changes.
Badminton is scored by rally point: the side that wins a rally scores a point and serves the next one. A match is the best of three games. Under the Laws in force until 3 January 2027 a game is won at 21, by two clear points, capped at 30; under the BWF 3×15 system it is won at 15, by two clear points, capped at 21.

How to keep score in badminton with the counter
Set the match up once, then it is one tap per rally, to whoever won it.
Choose the scoring system
3×21 is the Laws in force until 3 January 2027. 3×15 is the BWF system from 4 January 2027. If your league has its own date, pick what it plays.
Choose singles or doubles, and who serves first
The toss decides the first server. In doubles, player 1 of each pair starts in the right court; use the swap button before the first rally if your pair has chosen otherwise.
Tap the side that won each rally
Rally scoring gives a point to the winner of every rally, whoever served, so there is only ever one question to answer: who won it. A and L on a keyboard do the same.
Read the serving line before the next serve
Each side shows whether it is serving or receiving and from which court. In doubles it names the player, which is the part a turn-order habit gets wrong.
Take the interval and change ends when called
The flag line calls the 60-second interval at 11 or 8, the change of ends in the deciding game, and game point and match point as they arise.
Undo a mis-tap at once
Undo unwinds the last rally completely, including the serve, the positions and a game it ended, so a wrong tap at 20–19 can be taken back cleanly.
Where a badminton score counter gets used
Any game without an umpire, which is almost every game of badminton played.
Club nights
Doubles with rotating partners, where the question of who serves from which side comes up every few rallies and nobody wants to stop and argue it.
School and PE lessons
A phone at the side of the court, a clear call line and the service court shown, so the rules are taught by the score rather than around it.
League and county matches
Keeping a parallel count, and switching to 3×15 on the date your league does, whether that is 4 January 2027 or later.
Practising the new system
Playing 3×15 games before January, when setting at 14–all and the cap at 21 are still unfamiliar.
Coaching
Scoring conditioned games from the side of the court, with undo for the rallies you called wrong.
Social and family games
A garden or sports-hall game where the score is otherwise kept in two people’s heads and disputed at 19–all.
Badminton scoring changes on 4 January 2027, and the free scorers are still built for 21
On 25 April 2026, at its annual general meeting in Horsens, Denmark, the Badminton World Federation voted by the required two-thirds majority to replace the 21-point game with a 15-point one. The 3×15 scoring system comes into force on Monday 4 January 2027. Matches stay best of three games and rally scoring does not change. Almost everything else about when a game ends does.
The free scorekeepers at the top of a search for a badminton score counter, checked on 2026-09-24, are built around 21: Digital Tally Counter scores to 21 capped at 30, BadmintonTrack describes 21 with a 30-point maximum, and KeepTheScore defaults to 21 capped at 30, with an option to play 15 or 11 “if your local rules vary”. None of the three mentions the 3×15 system or that the change is coming. And a 15-point target is not the 3×15 system: setting from 14–all, the cap at 21 and the interval at 8 are what make it that, which is why it is a setting here with all three rules attached rather than a number you type in.
| Rule | 3×21 (to 3 January 2027) | 3×15 (from 4 January 2027) |
|---|---|---|
| Points to win a game | 21 | 15 |
| Setting (win by two from) | 20–all | 14–all |
| Cap | 30: at 29–all the next point wins | 21: at 20–all the next point wins |
| Longest possible game | 30–29 | 21–20 |
| Interval in a game | Up to 60 seconds when the leader reaches 11 | Up to 60 seconds when the leader reaches 8 |
| Change of ends in the deciding game | When the leader reaches 11 | When the leader reaches 8 |
| Between games | Up to 120 seconds | Up to 120 seconds, unchanged |
| Games in a match | Best of three | Best of three, unchanged |
| Scoring method | Rally point: every rally scores | Rally point, unchanged |
| Service court | Server’s score even: right; odd: left | Unchanged |
Sources: the BWF announcements of the vote and of the key changes, and USA Badminton’s notice of the approval, which gives the same effective date. The 21-point rules are from the BWF Simplified Rules of Badminton.
Setting starts earlier than people expect
The most common mistake in the first 15-point games will be carried over from 21. At 14–13 the side on 14 is on game point, and 15–13 wins it. But 14–14 is not game point for anybody: from there a side needs a two-point lead, so 15–14 plays on and 16–14 wins. The ceiling is 21, not 30, so a long setting ends at 21–20, and that last point is sudden death. The scorer above marks game point and match point as they arise under whichever system is selected, so nobody has to remember which numbers belong to which.
The interval moves, and so does the change of ends
Under 21 points the mid-game interval comes when the leading side reaches 11. Under 15 it comes at 8. In a deciding third game the players also change ends at that score, so that neither side plays most of the decider with the drift or the lights in its favour. In club play, forgetting the change of ends in a third game is common enough that the scorer calls it out at the moment it falls: 11 or 8, depending on the system.
What this does not change
Every rally still scores a point, whoever served. The server’s score still decides the service court. The winner of a game still serves first in the next, and ends still change after each game. Doubles rotation is identical. Only the numbers at which a game ends, pauses and turns around have moved, which is why one scorer with a switch can serve both.
Who serves, from which court: a rule, not a rotation
Club players tend to learn doubles service as a turn order — you serve, then I serve — and it is not one. Two rules decide everything, and the counter above follows them rather than a rotation:
- The server’s score picks the court. Even, including love: the right service court. Odd: the left. The receiver is the opponent standing in the court diagonally opposite, so the same number picks the receiver too.
- Only a side that wins a rally on its own serve moves. The server and partner swap courts and the same player serves again. A side that wins the serve back does not move at all; whichever of its players is already standing in the court its new score calls for becomes the server.
Follow four rallies of a doubles game with side A serving first, A1 and B1 each starting in the right court:
| Rally won by | Score (A–B) | Next server | From | Receiver | Who moved |
|---|---|---|---|---|---|
| Start of game | 0–0 | A1 | Right | B1 | Nobody |
| A | 1–0 | A1 | Left | B2 | A1 and A2 swap |
| B | 1–1 | B2 | Left | A1 | Nobody |
| B | 1–2 | B2 | Right | A2 | B1 and B2 swap |
| A | 2–2 | A2 | Right | B2 | Nobody |
Look at the last row. Side A won the serve back, and the player serving is A2, even though A1 served every one of A’s earlier points. Nobody on A chose that: A2 happened to be standing in the right court, and A’s score of 2 is even. That is the moment a turn-order habit sends the wrong player to the line, and it is why the counter shows the name of the server and the receiver in doubles, not just the side.
Singles is the same rule with one player
In singles there is no partner to swap with, so only the first rule applies: serve from the right on an even score and from the left on an odd one, and receive in the court diagonally opposite. At 7–4 the server is in the left court. At 4–7, with the other player serving on 7, it is also the left.
Calling the score
The server’s score is called first, and zero is love. When the serve changes hands, the umpire calls service over before the score, so 4–5 with the serve just won back by the side on 5 is called “service over, 5–4”. The call line above follows that order, which is useful when one player keeps score aloud for four.

Frequently asked questions
How does badminton scoring work?
Badminton uses rally point scoring: whichever side wins a rally scores a point, whoever served, and serves the next rally. A match is the best of three games. Until 3 January 2027 a game is won at 21 with a two-point lead, capped at 30. From 4 January 2027, under BWF 3x15, it is won at 15 with a two-point lead, capped at 21.
What is the new badminton scoring system?
The 3x15 system, adopted by the Badminton World Federation at its annual general meeting on 25 April 2026. Matches stay best of three games, but each game is played to 15 points instead of 21. From 14-all a side needs a two-point lead, and at 20-all the next point wins. The interval moves from 11 to 8.
When does 15-point badminton start?
The BWF 3x15 scoring system comes into force on Monday 4 January 2027. National associations and leagues decide when their own domestic events change, and at least one, India's, adopted it ahead of the global date. If you are unsure, the tournament prospectus or your league secretary will say which system applies.
What happens at deuce (20-20) in badminton?
Badminton calls it setting rather than deuce. Under 21-point scoring, at 20-all a side must win by two points, so 21-20 plays on and 22-20 wins. If it reaches 29-all, the next point wins, 30-29. Under 3x15 the same happens earlier: setting begins at 14-all and the game is capped at 21.
What is the maximum score in badminton?
Under the 21-point laws the maximum is 30: at 29-all the side scoring the next point wins the game 30-29. Under the BWF 3x15 system, from 4 January 2027, the maximum is 21: at 20-all the next point wins the game 21-20. No game can go beyond either cap, however long the setting lasts.
Which side do you serve from in badminton?
The server's own score decides it. When the server's score is even, including zero, they serve from the right service court; when it is odd, from the left. The receiver stands in the court diagonally opposite. The opponent's score plays no part, so at 3-6 the server on 3 serves from the left.
How does doubles serve rotation work in badminton?
There is no fixed rotation. When the serving side wins a rally, the server and partner swap courts and the same player serves again. When the receiving side wins, it gains the serve and nobody moves: whichever of its players is standing in the court its new score calls for serves. That can be the player who did not serve last time.
When do players change ends in badminton?
At the end of each game, and in a deciding third game when the leading side reaches 11 points under 21-point scoring, or 8 points under the BWF 3x15 system. Changing ends in the decider stops one side playing most of it with the drift, the lights or the better background in its favour.
How many games are in a badminton match?
A match is the best of three games, so the first side to win two games wins the match. That is true under both 21-point scoring and the BWF 3x15 system. The winner of a game serves first in the next one, and there is an interval of up to 120 seconds between games.
Is this an official badminton score sheet?
No. It is a scorer for club, school and friendly games. In a sanctioned match the umpire's score sheet is the record and the tournament's regulations decide the scoring system. The counter keeps the score in this browser only; nothing is sent anywhere, and clearing site data clears it.
