Badminton is one of the easiest racket sports to pick up and one of the hardest to master โ but before you worry about smashes and footwork, you need to know how a game actually works. This guide walks through the basic badminton rules every beginner should understand: the court and equipment, how to serve legally, how rally scoring to 21 works, the most common faults and lets, and how rotation works in doubles. Read it once and you can walk onto any court and play a proper game.
Court and Equipment Basics
A badminton court is a rectangle 13.4 metres long. The width depends on the format: 6.1 metres wide for doubles and 5.18 metres wide for singles. The difference is the two outer side strips โ in singles, the narrower inner sidelines are used, while doubles uses the full width including the outer strips.
The net is stretched across the middle. Its height is 1.55 metres at the posts and dips slightly to about 1.524 metres at the centre. Unlike tennis, the shuttle can never bounce โ if it touches the floor on your side, you lose the rally.
Two more lines matter for serving. The short service line sits 1.98 metres from the net, and the long service line for doubles runs 0.76 metres inside the back boundary. For singles, the back boundary line itself is the long service line, so the singles service box is long and narrow, while the doubles box is short and wide.
Court: 13.4 m long ยท 6.1 m wide (doubles) / 5.18 m (singles). Net: 1.55 m at the posts. Short service line: 1.98 m from the net.
Serving Rules
The serve is the most rule-heavy moment in badminton, and beginners get called for faults here more than anywhere else. The core rules:
- Hit below 1.15 metres. Under the current laws, the entire shuttle must be below 1.15 m from the court surface at the instant your racket strikes it, and the racket shaft must point in a downward direction at contact.
- Serve diagonally. You always serve into the service court diagonally opposite you. Serve straight ahead and it is a fault.
- Feet behind the lines. Both server and receiver must stand inside their respective service courts, with some part of both feet on the ground, and must not step on any boundary line until the shuttle is struck.
- One attempt only. Once you start the forward motion of the serve, you must hit the shuttle โ you cannot stop and restart, and a missed swing counts as a fault.
Which side you serve from depends on your score in rally scoring: when the server's score is even, serve from the right service court; when it is odd, serve from the left.
The target box also changes by format. In singles, you serve into the long, narrow box โ all the way to the back boundary. In doubles, the serve must land short of the doubles long service line, but the full width including the outer strips is in play. After the serve is returned, the back boundary is live again in doubles too.
Scoring Basics
Modern badminton uses rally scoring: every single rally produces a point, no matter who served. Win the rally, win the point โ and the right to serve next.
- A game is played to 21 points, and you must lead by at least two.
- At 20-20, play continues until one side leads by two points โ with a hard cap at 30 points, so 30-29 ends the game.
- A match is the best of three games. Players switch ends after each game, and mid-way through a deciding third game.
That is enough to keep score in your first match. For the deeper details โ what happens at 29-29, when the service changes in doubles, and how interval breaks work โ see our full guide to the badminton scoring system.
Faults and Lets
A fault ends the rally and gives the point to the other side. Beyond serving faults and hitting the shuttle out, the most common ones for beginners are:
- Hitting the net. If your racket, body or clothing touches the net or its posts while the shuttle is in play, it is a fault โ even after you have hit your shot.
- Reaching over the net. You must strike the shuttle on your own side. Following through over the net after contact is fine; reaching across to hit it early is not.
- Holding or slinging the shuttle. The shuttle must be struck cleanly. If it is caught on the racket and thrown, or hit twice in succession by the same player, it is a fault.
- Double hit in doubles. Two partners hitting the shuttle one after the other in the same return is a fault.
- Obstruction. Deliberately blocking your opponent's shot with your racket or body is a fault.
A let means the rally is replayed with no point awarded. Lets happen when the shuttle gets tangled in the top of the net and stays there after passing over (except on the serve), when the shuttle disintegrates mid-rally, when both sides fault at the same time, or when the receiver was simply not ready. One classic beginner question: a serve that clips the net and still lands in the correct service court is legal โ play on, no let.
Doubles Rotation Basics
Doubles confuses new players because the serving side keeps swapping positions. The logic is actually simple and follows directly from the even/odd serving rule:
- Only the side that won the previous rally serves. When the serve passes to your team, the player in the correct court serves โ right court if your score is even, left if odd.
- When the serving side wins a rally, the same player serves again from the other side โ so the two partners swap courts.
- When the receiving side wins a rally, they do not swap; whoever is standing in the correct court for their new score takes the serve.
The takeaway: your position always mirrors your team's score โ even score means the server stands on the right. If you ever lose track mid-game, ask for the score and count back from there.
Frequently Asked Questions
Is a serve that hits the net but lands in legal?
Yes. If the shuttle clips the top of the net on a serve and still lands inside the correct diagonal service court, the serve is good and play continues. Unlike some other racket sports, the serve is not replayed for a net cord.
Who calls whether the shuttle is in or out?
In casual matches without an umpire, each side calls the lines on its own half of the court, and honesty is part of the game. If you genuinely cannot tell, the fair convention is to give your opponent the benefit of the doubt or replay the rally.
What happens if the shuttle touches the ceiling or a wall?
It is a fault against the player who hit it. Some venues with very low ceilings use local let rules for recreational play, so agree on this before the match starts.
Can I reach over the net to hit the shuttle?
No โ you must make contact with the shuttle on your own side of the net. Your racket may follow through over the net afterwards, provided you never touch the net or interfere with your opponent.
How high can I hold the shuttle when serving?
The whole shuttle must be below 1.15 metres from the court surface at the moment it is struck, and the serve must travel upward into the diagonally opposite service court.
How many points do you need to win a game?
21 points with rally scoring, winning by two, capped at 30. A match is the best of three games. Our scoring system guide covers the edge cases.
