Plenty of people play badminton socially for years without ever learning the official rules — and then their first club night feels like a pop quiz. This guide covers the rules you will actually need, in plain English, so you can step onto court at any Australian badminton centre with confidence.
Scoring: rally point to 21
Modern badminton uses rally scoring: whoever wins the rally wins the point, regardless of who served. Games are played to 21 points, and you must win by two clear points. If the score reaches 20–20, the game continues until one side leads by two — with a hard cap at 30: the first side to 30 wins a deuce game that has gone on forever.
A match is the best of three games. Between games there is a short break, and at 11 points in each game there is a brief interval — this is where coaching and tactics discussions legally happen in most competitions.
Serving: the rules that trip everyone up
- Serve from below the waist. The racket must contact the shuttle below your lowest rib line, with the racket head pointing downward at contact. No tennis-style serves.
- Both feet stationary and in contact with the floor in the correct service court.
- You score, you serve. If the server wins the rally, they serve again from the opposite court (in doubles) or the same court logic applies in singles based on your own score being even or odd.
- Even/odd courts (singles): when your score is even (0, 2, 4…), you serve from the right court; odd, from the left. It sounds confusing until you play it once — then it sticks.
You lose the rally when…
- The shuttle lands in or out — yes, landing on the line counts as in ("line is good").
- You hit the shuttle twice, or "carry" it on the racket (a double hit or sling).
- You reach over the net to hit the shuttle before it crosses — though following through across the net plane after contact is legal.
- You touch the net or posts with your racket, body or clothing.
- You deliberately distract an opponent (shouts, waving, fake calls).
Singles vs doubles courts
The side alleys are "in" for doubles and "out" for singles; the back tramlines are "in" for both — except during the doubles serve, when the back alley is out. This one catch alone causes a hundred arguments a week in social badminton, so settle it now.
What you need to play properly
Rules knowledge makes you legal; equipment makes you competitive. A strung racket suited to your game (see our racket selection guide) and — non-negotiably — court shoes with gum-rubber soles, because most centres will not let you on the floor in marking soles anyway. The reasons go far beyond house rules: our running shoes vs court shoes guide explains the ankle-sprain mechanics.
