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. For a mixer where partners change every game, the Americano rotation, built for padel, draws the pairings and totals each player’s points for badminton doubles just as well, because every rally scores there too.
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. If the game has no service rules to follow at all, the plain online counter is one tap per point.
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. Pickleball uses the same even-right, odd-left rule, applied to the serving team’s score in doubles, as the pickleball score counter applies.
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.
Faults, lets and service court errors: which ones score a point
Under rally scoring every rally ends in one of three ways, and only one of them changes the score. A scorer who knows which can keep a club game moving without an umpire. From the Laws of Badminton, which read the same in the 2025 edition in force now and in the edition the BWF adopted on 25 April 2026:
| Call | What it is | The score | The next serve |
|---|---|---|---|
| Fault (Law 13) | A side broke a rule: an incorrect service, the shuttle landing out or failing to cross the net, touching a player, hit twice, a net touch or obstruction | The other side scores a point | From the side that scored, like any rally won |
| Let (Law 14) | Play stopped for something neither side is punished for | No point: “play since the last service shall not count” (14.3) | The player who served last serves again |
| Service court error (Law 12) | A player served or received out of turn, or from the wrong service court | Unchanged: “the existing score shall stand” (12.2), including the rally just played | The error is corrected when the shuttle is not in play |
So in the counter above a fault is one tap, for the side that did not commit it; a let is no tap at all; and a service court error is no tap either: the score stands, and the serving line already shows the player and court the score calls for, which is where the correction puts everyone.
Calls that club players get wrong
| Situation | Call | Law |
|---|---|---|
| The serve clips the net and lands in the right service court | Good: play on. There is no net-cord let on the serve, as in tennis | 9.1, 13.2 |
| The serve is caught on top of the net, or in it after passing over | Fault | 13.2 |
| The same thing happens later in the rally | Let (a fault in wheelchair badminton) | 14.2.3 |
| The shuttle lands on the line | In: a fault only if it lands “not on or within the boundary lines” | 13.3.1 |
| Server and receiver both fault on the serve | Let, not a point to either | 14.2.2 |
| The server serves before the receiver is ready | Let, unless the receiver tried to return it, which counts as ready | 14.2.1, 9.4 |
| The shuttle is hit above 1.15 m on the serve | Fault: the whole shuttle must be below 1.15 metres from the court when it is hit | 9.1.6, 13.1 |
| The shuttle hits the frame and strings in one stroke | Not a fault | 13.3.7 |
| The shuttle falls apart and the base comes off | Let | 14.2.4 |
| The wrong player serves in doubles, and it is noticed after the rally | Service court error: the point stands, the positions are corrected | 12.1, 12.2 |
Without an umpire, Law 14.1 lets a player call a let. The Laws give a let when a line judge is unsighted and the umpire cannot decide (14.2.6), but say nothing about two players who simply disagree on a line; replaying it by agreement is the club habit, and in the counter that is the same as a let: no tap.
15 points again, but not the old 15: side-out, 3×21 and 3×15 compared
Fifteen points is not new to badminton, which is why the 3×15 change confuses anyone who learned the game before 2006, and why some rule summaries online still describe the old game as if it were current. Until 2006 badminton was scored by side-out: only the serving side could win a point, and a rally lost on your own serve simply passed the serve over. Men’s singles and all doubles went to 15, women’s singles to 11. The world federation, then the International Badminton Federation and renamed the BWF later in 2006, trialled rally scoring to 21 in December 2005 and adopted it in August 2006. The 2027 system brings back the number 15 and keeps everything else about rally scoring.
| Rule | Side-out (until 2006) | 3×21 rally (2006 to 3 January 2027) | 3×15 rally (from 4 January 2027) |
|---|---|---|---|
| Who can score | Only the serving side | Whoever wins the rally | Whoever wins the rally |
| Points to win a game | 15; women’s singles 11 | 21, every event | 15, every event |
| A close game | Setting by choice: at 13–all or 14–all (9–all or 10–all in women’s singles) the side that got there first could extend the game | Win by two from 20–all | Win by two from 14–all |
| Highest winning score | 18 after setting at 13–all (until 2002), 17 at 14–all; 12 in women’s singles | 30, at 30–29 after the golden point at 29–all | 21, at 21–20 after the golden point at 20–all |
| Doubles serving | Both partners served before the serve passed over | One serve per side; the server’s score picks the court | Unchanged from 3×21 |
| Games in a match | Best of three | Best of three | Best of three |
Sources: Scoring system development of badminton for the side-out game, its setting rules, the December 2005 trial and the August 2006 adoption; the BWF and USA Badminton for 3×15, which member associations approved by 198 votes to 43, as The Bridge reported. Two other experiments came and went: five games to 7 in 2002, and five games to 11, trialled from August to November 2014. A 3×15 match is still best of three games, not five.
The golden point
Rally scoring needs a ceiling, or a level game could run for ever. Under 3×21, at 29–all the next rally wins the game 30–29, and players call it the golden point. Under 3×15 the same point comes at 20–all and ends the game 21–20. Under rally scoring it is the only way a game is won by a single point, and the counter above ends the game on it under whichever system is selected.
Which final scores can happen
A game ends the moment a side reaches the target with a two-point lead, or wins the golden point, so a score sheet can be checked against the rules alone. Only these final scores can appear:
| System | Won outright | Won after setting | Golden point | Never a final score |
|---|---|---|---|---|
| 3×21 | 21–0 to 21–19 | 22–20 to 29–27, and 30–28 | 30–29 | 21–20, 30–27, 31–29 |
| 3×15 | 15–0 to 15–13 | 16–14 to 20–18, and 21–19 | 21–20 | 15–14, 21–18, 22–20 |
So a game recorded as 21–20 before 4 January 2027 was stopped one rally early, while the same 21–20 is a correct golden-point finish under 3×15. The counter does not end a game on a score outside this table for the system selected.
If your group still plays side-out
Some school and garden games are still played the old way, to 15 with only the server scoring. That is not a setting here, because no current Laws use it. Score it on the plain score counter, adding a point only when the serving side wins the rally.

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 a fault in badminton?
A fault is a broken rule that ends the rally and gives the other side the point: an incorrect service, a serve caught in the net, the shuttle landing outside the lines, failing to cross the net, touching a player, being hit twice, or a player touching the net or obstructing an opponent (Law 13). A shuttle on the line is in.
What is a let in badminton?
A let stops play without a point to anyone: the rally does not count and the player who served last serves again (Law 14.3). It is called when the server serves before the receiver is ready, when server and receiver both fault, when the shuttle is caught on the net after the serve has been returned, or the shuttle falls apart.
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.
What is the golden point in badminton?
The golden point is the deciding rally at 29-all under 21-point scoring: a game cannot go past 30, so whoever wins that rally wins the game 30-29. Under the BWF 3x15 system, from 4 January 2027, the same point comes at 20-all and ends the game 21-20. Under rally scoring it is the only way a game is won by a single point.
Is the new 15-point system the same as the old badminton scoring?
No. Before 2006 badminton also played to 15, but only the serving side could score, women’s singles went to 11, and both doubles partners served before the serve passed over. The BWF 3x15 system from 4 January 2027 keeps rally scoring: every rally scores a point whoever served, with setting from 14-all, a cap at 21 and three games, not five.
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 how to fill in a badminton umpire scoresheet explains the BWF method; 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.
