A Beginner's Guide to Badminton Scoring Rules

Understand singles, doubles and mixed scoring, service changes and common faults so you can play confidently from your first match.

How a Badminton Match Is Structured

Modern badminton runs on the rally point system, and it has done since 2006, so you can forget the old "only the serving side scores" rules your parents might remember. Every rally you win is a point. Every rally you lose hands a point — and the serve — to your opponent. It is fast, it is brutal, and it is wonderfully simple once it clicks.

A match is the best of three games. Each game is played to 21 points, and you must win by two clear points. So 20-20 becomes a tense race to 22-20, and if it somehow drags on to 29-29, the next point wins it. 30 is the absolute maximum score.

Within a game there is a 60-second interval when the leading side reaches 11 points, and a two-minute break between games. You change ends at the end of every game, and in the deciding game you swap again when one side reaches 11.

Scoring in Singles

Singles is the simplest format to learn, and it teaches you court awareness beautifully. The rule to burn into memory is this: if your score is even, you serve from the right service court; if it is odd, you serve from the left. Server's score is always called first, so the umpire or your opponent should announce "8-5" before serving — the eight belongs to the person about to serve.

Keep winning rallies and you keep serving, alternating service courts with every point you score. Lose a rally and the serve passes to your opponent, who then serves from whichever court matches their own score.

The singles court is long and narrow. The side tramlines are out, and the back boundary line is the limit — there is no long service line to worry about. A serve that skims the back line is perfectly legal; one that drifts into the tramlines is not.

Doubles and Mixed Doubles

Doubles follows the same 21-point framework but adds one twist that trips up almost every newcomer: you and your partner swap sides every time your side wins a point while serving.

Here is how it works. Only one player from each pair serves. The first serve of the game always comes from the right service court. If you serve and win the rally, you serve again — but from the left court, with your partner opposite you. Keep scoring and you keep rotating. The moment you lose a rally, nobody moves at all; the opponents simply take over the serve and position themselves according to their own score.

The doubles service court is wide but short. The side tramlines count as in, but the service court ends at a line 76cm in front of the back boundary. A deep serve that would be a winner in singles is a fault in doubles, so keep it short and attacking.

Only the receiver may return the serve. If the receiver's partner touches the shuttle, even accidentally, that is a fault against them. Mixed doubles uses identical rules — the only difference is convention, with most pairs settling into a front-and-back formation, the stronger smasher covering the rear court.

Service Rules You Absolutely Must Know

The serve is the most rule-heavy shot in the sport, and it is where beginners lose the most cheap points. Get these right from day one:

Both feet must be on the floor, stationary, not touching any boundary line, until the shuttle is struck.
At the moment of impact, the whole shuttle must be below 1.15 metres from the court surface.
The racket must move continuously forward — no feints, no double movements, no delaying tactics.
The shuttle must be struck from your hand. If you swing and miss completely, that is a fault.
In singles, you serve from the right or left service court; the shuttle must land in the diagonally opposite box.

If your serve clips the net on the way over and still lands in the correct box, play continues. There is no "let" for a net-cord serve in badminton, unlike tennis — a small mercy worth knowing.

Common Faults and How to Avoid Them

Most faults at club level are honest mistakes rather than gamesmanship, and they are easy to iron out:

Lifting your foot during the serve. Freeze your stance for a beat longer than feels natural.
Serving too high. Practise with a partner watching; a shuttle hovering around the hip line is usually safe.
Touching the net. Your racket, clothing or body must never touch the net or its posts while the shuttle is in play.
Hitting the shuttle twice or catching and slinging it rather than striking cleanly.
Letting the shuttle hit you. If it touches your body or clothing, that is your opponent's point.
Obstructing an opponent by blocking their swing or distracting them while the shuttle is in play.

If you and your opponent genuinely cannot agree on a line call, the sporting solution at club level is to replay the point and move on. Nobody remembers the rally; everybody remembers the argument.

Putting It Into Practice at Your Club

The quickest way to absorb all of this is to call the score out loud before every single serve, even in a casual knockabout. It forces you to track who is serving, from which court, and it makes you a much more reliable partner in doubles.

At club nights across Derbyshire you will rarely have an umpire, so the players police themselves. Agree the basics before you start, keep your own score honestly, and rotate partners so you experience both the right and left service courts. Within a couple of sessions the whole system becomes second nature — and you can get on with the far more enjoyable business of actually winning rallies.
