Badminton scoreboard online
This badminton scoreboard counts rally points for singles and doubles: tap the side that won the rally and the board closes each game at the right score, tells you who serves from which service court and announces the interval and the change of ends. Use it on a phone at the court, in the school hall or at your society’s weekend tournament.
How it is calculated
Badminton is scored by rally points: whoever wins the rally gets a point and serves next. A match is the best of three games; under the system in force a game is won at 21 points, at 20–20 with a two-point lead, and at 29–29 by the 30th point. This badminton scoreboard applies those rules for you.
How to use the badminton scoreboard
- Enter the players or pairs, choose the scoring system and who serves first.
- After every rally, tap the big box of the side that won it. The ● marks the server, and the line below says from which service court the serve is taken.
- At the end of a game the board records the game score and opens the next game; the winner of a game serves first in the next one.
- “Undo point” removes the last rally. “Full screen” and “Swap sides” help when the phone or tablet stands next to the court.
Both scoring systems side by side
| Rule | 3 × 21 (in force now) | 3 × 15 (from 4 January 2027) |
|---|---|---|
| Points to win a game | 21 | 15 |
| Two-point lead needed from | 20–20 | 14–14 |
| Deciding point | at 29–29 the 30th point wins | at 20–20 the 21st point wins |
| Interval within a game | when the leading score reaches 11 | when the leading score reaches 8 |
| Change of ends in the third game | at 11 | at 8 |
Example in the 21 system: from 20–20 the game goes on until one side leads by two, such as 22–20 or 25–23. If it stays level up to 29–29, the next rally decides: 30–29. The 3 × 15 system was approved by the BWF Annual General Meeting on 25 April 2026 and, according to that decision, applies from the first week of 2027 (Monday, 4 January 2027); the BWF Council may adjust the date. That is why the board offers both.
Which service court?
The server stands in the right service court when their own score is even (0, 2, 4 …) and in the left service court when it is odd. The scoreboard shows this after every rally. In doubles the same rule decides the court; which partner serves follows from the positions on court, which the board cannot see – a pair only changes service courts when it wins a point on its own serve.
Intervals and change of ends
- During a game: an interval of up to 60 seconds when the leading score first reaches 11 (or 8 in the 15 system).
- Between games: an interval of up to 120 seconds, and the players change ends.
- Third game: ends are changed again when the leading score reaches 11 (or 8).

Frequently asked questions
How many points is a game of badminton?
Under the system in force, 21 points. At 20–20 a side must lead by two, and at 29–29 the 30th point wins. A match is the best of three games.
What is the 3 × 15 scoring system?
A new BWF system approved on 25 April 2026: games to 15 points, a two-point lead from 14–14, and at 20–20 the 21st point wins. According to that decision it applies from 4 January 2027. Choose “3 × 15” under “Scoring system” to use it already.
Who serves after a rally?
The side that won the rally. If the server wins, the same player serves again from the other service court; if the receiver wins, the serve passes over.
From which side do I serve?
From the right service court when your score is even, from the left when it is odd. The scoreboard prints the correct court under the score.
When is the interval, and when do players change ends?
There is an interval of up to 60 seconds when the leading score reaches 11 (8 in the 15 system) and up to 120 seconds between games, when ends are changed. In the third game ends are changed again at 11 (or 8).
Does the scoreboard work for doubles?
Yes. The scoring is identical; type both partners into one name box. The board shows the serving pair and the service court, not which partner serves.
Can I take back a point?
Yes, with “Undo point”. It removes the last rally, including one that ended a game.
Do I need to install an app?
No. The scoreboard runs in the browser, is free and needs no account.
