Badminton Scoring and Rules Explained: A Simple Guide for Beginners and Parents
Confused by badminton scoring? Learn how points, service, faults, and match format work, with a simple rules guide for beginners and parents.
Badminton uses rally-point scoring. A match is the best of three games; each game goes to 21 points, and the winner of every rally scores a point, whether they served or not. A player must win by two clear points, and if the score reaches 29-29, the first to 30 wins.
How Badminton Scoring Works
- Match format: first to win two games wins the match.
- Every rally scores: there is no separate serving point.
- Win by two: at 20-20, play continues until one side leads by two, up to a limit of 30.
- Who serves next: the side that won the previous rally.
- Breaks: a 60-second pause when the leading score reaches 11, and two minutes between games.
- Changing ends: after each game, and in the deciding game when the leading score reaches 11.
How the Serve Works
The serve is hit diagonally into the opposite service court. The server serves from the right court when their score is even, and from the left when it is odd. At the moment of contact, the whole shuttle must be below 1.15 metres from the floor, and the server’s feet must stay still and in contact with the ground until the serve is hit. The serve must be a smooth, continuous motion without delay.
Singles vs Doubles Court Lines
| Singles | Doubles | |
| Court width in rallies | Narrower (inner side lines) | Wider (outer side lines) |
| Service court | Long and narrow | Short and wide |
| Serve goes to | The back boundary line | The doubles long service line |
Common Faults
A fault gives the point to your opponent. The most common ones are:
- The shuttle lands outside the lines or hits the ceiling.
- The shuttle goes under or through the net, or fails to cross it.
- A player touches the net with their racket, body, or clothing during a rally.
- A player hits the shuttle twice in a row, or reaches over the net to hit it before it crosses.
- The serve is hit above the legal height, or the server moves their feet or delays.
A let is different. It means the rally is replayed, for example, when the shuttle gets caught on the net or something unexpected interrupts play.
What Parents Should Know at Junior Tournaments
Junior matches follow the same scoring, but a few practical points help you stay calm in the stands:
- Umpires and service judges may call faults, especially for service height. This is normal, and coaches work on it in training.
- Coaching during matches is usually allowed only in the intervals, though local rules vary.
- Formats can be knockout or round-robin, and age categories differ by tournament. Check the schedule before you travel.
- Arrive early. Matches often run ahead of schedule, and late arrivals may lose their match by default.
Rules Make the Game More Enjoyable
Once the rules click, matches become easier to follow and far more fun to play. Beginners often learn them fastest on court, with a coach calling faults in real time. If you play doubles, our doubles strategy guide shows how positioning works with these rules. New to the sport?

FAQs
How many points do you need to win a badminton game?
You need 21 points and a lead of two. If the score reaches 29-29, the first side to 30 wins the game.
How many games are in a badminton match?
A match is the best of three games, so the first side to win two games wins the match.
Where must a badminton serve land?
The serve must go diagonally into the opposite service court, inside the lines. In singles the service court is long and narrow, and in doubles it is short and wide.
What is a let in badminton?
A let is a replay of the rally. It is called when something unexpected interrupts play, such as the shuttle getting stuck on the net, and it does not give a point to either side.
