Badminton Scoring Explained: How Points, Games, and Matches Work

Badminton scoring is much easier once you understand one basic idea:

The winner of each completed rally earns one point. A let is replayed without a point.

Under the standard international BWF system in force in October 2026, badminton matches are normally played as the best of three games, with each game played to 21 points. If the score reaches 20–20, however, the game continues until one side leads by two points—unless the score reaches 29–29, when the next point wins.

There is also an important change coming. BWF members approved a new best-of-three games to 15 points system for international implementation beginning January 4, 2027.

This guide explains the current 21-point system first, then shows exactly what changes under the new 15-point format.

Scoring update — October 2026: The standard international BWF scoring system remains 3×21 through the end of 2026. Some national associations and specific events have already adopted 3×15 early, so always check the competition rules you are actually playing under.

Badminton Scoring in 30 Seconds

Under the current standard system in 2026:

• the side winning a completed rally earns one point; a let earns no point;
• a game is normally played to 21 points;
• a match is normally the best of three games;
• at 20–20, a side must gain a two-point lead;
• at 29–29, the next point wins the game 30–29;
• the side that wins a game serves first in the next game.

For example:

21–17 = game over.

21–20 = keep playing.

22–20 = game over.

30–29 = game over because 30 is the cap under the current 21-point system.

That is the core of badminton scoring.

How Rally Scoring Works

Modern badminton uses rally scoring.

That means the side winning a completed rally gets a point, regardless of which side served. If a let is called, no point is awarded and the last server serves again.

Imagine the score is:

Player A: 7
Player B: 5

If Player B wins the next rally, the score becomes:

Player A: 7
Player B: 6

Player B gains or keeps the right to serve according to the service rules.

You do not need to be the serving side to score.

How Many Points Do You Need to Win a Game?

Under the current standard BWF system, the normal target is 21 points.

If one side reaches 21 while leading by at least two points, the game ends.

Examples of completed games include:

• 21–10
• 21–18
• 21–19
• 22–20
• 25–23
• 30–29

Not every game ends at exactly 21.

That depends on whether the score becomes tied at 20–20. If you also need to check whether a shuttle landed in or out, see our Badminton Court Dimensions and Lines guide.

What Happens at 20–20?

At 20–20, the game enters what many players casually call deuce.

Neither side can win simply by scoring the 21st point.

A side must gain a two-point lead.

For example:

20–20 → 21–20 → 22–20

The game ends at 22–20 because one side finally leads by two.

But if the player who is behind wins the next rally:

20–20 → 21–20 → 21–21

the game continues.

The two-point requirement remains in effect until one side creates that two-point gap—or the game reaches the maximum-score rule.

What Happens at 29–29?

A badminton game cannot continue forever under the current scoring system.

If the score reaches:

29–29

the next rally decides the game.

So:

30–29

is a winning score.

There is no need to win 31–29.

This is the hard cap under the current 21-point format.

How Do You Win a Badminton Match?

A standard badminton match is the best of three games.

That means the first side to win two games wins the match.

Possible match results include 2–0 or 2–1.

Example 1 — Straight-games win

Player A wins:

Game 1: 21–15
Game 2: 21–18

Player A wins the match 2–0.

There is no third game because Player A has already won two games.

Example 2 — Three-game match

Player A wins Game 1: 21–17

Player B wins Game 2: 21–16

The match is now tied at one game each.

They play Game 3.

If Player A wins Game 3 21–19, Player A wins the match 2–1.

The points from all three games are not added together to decide the winner. The important thing is games won, not total points accumulated across the entire match.

Who Serves First in the Next Game?

The side that wins a game serves first in the next game.

So if Player A wins Game 1, Player A serves first in Game 2.

If Player B then wins Game 2, Player B serves first in Game 3.

In doubles, either player on the side that won the previous game may serve first in the next game, and either player on the other side may receive first.

How the Score Affects Your Service Court

Scoring also tells you which service court to use.

For a beginner, the easiest rule to remember is:

Even score = serve from the right. Odd score = serve from the left.

Use the serving side’s score: the player’s own score in singles or the team score in doubles.

So if the serving side’s score is:

• 0 → right service court
• 1 → left service court
• 2 → right
• 3 → left
• 4 → right
• 5 → left

and so on.

The serve always goes diagonally into the receiver’s correct service court. For serving height, faults, and legal contact, see Badminton Service Rules Explained.

Example

You are serving at 8–6.

Your score is 8.

Eight is even.

So you serve from the right service court.

If you win the rally, the score becomes 9–6.

Nine is odd.

You serve again, but now from the left service court.

If your opponent wins instead, your opponent scores a point and becomes the server. They choose their service side based on their own score.

Singles Scoring Example

Suppose Alex and Sam are playing singles.

The game begins:

0–0

Alex serves from the right because zero is even.

Alex wins the rally:

1–0

Alex serves again, this time from the left because one is odd.

Sam wins the next rally:

1–1

Sam gains the serve.

Sam’s score is one, which is odd, so Sam serves from the left service court.

The basic pattern continues:

• rally winner gets the point;
• rally winner becomes or remains the server;
• server uses the right court for an even score and left for an odd score.

Doubles Scoring Example

Doubles uses the same rally-scoring principle:

The side winning a completed rally still earns one point.

The serving side also uses:

even score → right

odd score → left

However, doubles adds a service-order and player-position sequence that can initially feel confusing.

If Team A is serving at 6–4, the correct Team A server serves from the right because Team A’s score is six.

If Team A wins the rally:

7–4

Team A keeps the serve, and the same server serves again from the opposite service court.

If Team B wins the next rally:

7–5

Team B gains the point and the serve. The correct Team B server serves from the left because Team B’s score is five.

The exact individual serving order matters in doubles, so do not simply switch servers whenever you feel like it. Our Badminton Doubles Rules for Beginners guide walks through the full sequence with a four-player example.

Do Singles and Doubles Use the Same Scoring System?

Yes, under the current standard BWF system.

Singles, men’s doubles, women’s doubles, and mixed doubles all use rally scoring with the same basic game and match structure.

The major differences between singles and doubles are more about court boundaries, service courts, serving and receiving order, positioning, and tactics. Our Badminton Doubles Rules guide covers the differences in more detail.

When Are the Intervals?

Under the current 21-point standard, players receive a mid-game interval of up to 60 seconds when the leading score first reaches 11 points.

There is also an interval of up to 120 seconds between games.

In a deciding third game, players change ends when one side first reaches 11 points.

These thresholds will change under the 15-point international system beginning in 2027. For the wider match and fault rules, read Badminton Rules for Beginners.

What Changes With the New 3×15 Scoring System in 2027?

BWF members approved the new scoring format in April 2026, with international implementation scheduled for January 4, 2027.

The match will still be best of three games and rally scoring remains.

Games will be played to 15 instead of 21

The normal target changes from 21 points to 15 points.

The two-point rule begins at 14–14

Under 3×15, if the score reaches 14–14, a side must gain a two-point lead.

Possible winning scores include 16–14, 17–15, and 18–16.

The new hard cap is 21

If the score reaches 20–20, the next point wins:

21–20

So the cap moves from 30 under the current 3×21 system to 21 under 3×15.

The mid-game interval moves to 8 points

The 60-second interval will occur when the leading side first reaches 8 points, instead of 11.

The third-game change of ends moves to 8

In a deciding third game, players will change ends when one side first reaches 8 points, rather than 11.

The break between games remains 120 seconds

The standard two-minute interval between games remains unchanged under the new format.

Rally scoring remains

Perhaps the most important thing beginners should understand is what does not change:

Every completed rally won earns a point.

The 2027 change is not a return to badminton’s old service-point scoring system.

Is 3×15 Already Being Used in 2026?

In some places, yes.

The international implementation date is January 4, 2027, but some national governing bodies and competitions have adopted the format earlier to prepare players and organizers.

So if you are playing in an organized event during the transition period, do not assume the score target based only on the calendar year.

Check the event regulations.

For a casual game with friends, agree on the scoring format before you begin.

How to Keep Score During a Casual Game

When you are learning, you do not need a professional scoreboard.

Simply say the score clearly before each serve.

A practical habit is to say:

server’s score first, receiver’s score second.

For example, if you are serving and you lead 9–6, announce:

“Nine–six.”

If your opponent wins the rally, the score becomes 9–7, and your opponent becomes the server.

From their perspective, they would announce:

“Seven–nine.”

Saying the score aloud helps both sides notice mistakes early. If you are learning to deliver a consistent legal serve, see How to Serve in Badminton.

Common Badminton Scoring Mistakes

Thinking only the server can score

Under rally scoring, the side winning a completed rally earns a point. A let is replayed without awarding a point.

Ending the game at 21–20

At 20–20 under the current system, you need a two-point lead unless the score reaches the 30-point cap.

So 21–20 is not a finished game.

Forgetting the 30-point cap

If the score reaches 29–29, the next rally wins the current 21-point game.

Serving from the wrong court

Remember:

even = right

odd = left

based on the server’s score.

Adding all points together to decide the match

Badminton matches are decided by games won, not by total points across all games.

Assuming every 2026 event uses 3×21

The standard international baseline remains 3×21 through the end of 2026, but some national competitions are already using 3×15.

Always check the event format.

Frequently Asked Questions About Badminton Scoring

Does every rally count as a point in badminton?

A completed rally won by one side earns a point. A let is different: it is replayed without awarding a point.

The side winning a completed rally receives a point, whether or not it served. If a let is called, the rally is replayed without a point.

How many points are needed to win a badminton game in 2026?

Under the standard international BWF system currently in force, the normal target is 21 points.

At 20–20, a side must lead by two, up to the 30-point cap.

What is the highest possible score in a 21-point badminton game?

The maximum winning score is 30–29.

What score is called deuce in badminton?

Players commonly use the term deuce when the score reaches 20–20 under the current 21-point format.

Who serves after winning a rally?

The side that wins the rally serves next.

If the serving side wins, it keeps the serve. If the receiving side wins, it gains the serve.

Why do badminton players switch service courts?

The serving side’s score determines the service court:

even → right

odd → left

How many games are in a badminton match?

A standard match is best of three games.

The first side to win two games wins the match.

What will the badminton scoring system be in 2027?

From January 4, 2027, the approved international standard is scheduled to become best of three games to 15 points, with rally scoring unchanged.

At 14–14, a two-point advantage is required, with a hard cap at 21.

Will all badminton games everywhere immediately use 15 points in 2027?

Not necessarily.

BWF’s international standard changes, but local recreational groups and individual competitions can use formats allowed or adopted under their governing rules.

Always check the event you are playing.
