Badminton is a racquet sport played with a shuttlecock, with each side consisting of one or two players. Matches are played in best-of-three sets, with each set won by reaching 21 points with a two-point lead. If the score reaches 20-20, play continues until a two-point advantage is achieved. The racquet is a critical piece of equipment, with modern racquets crafted from materials like carbon fiber composite, aluminum, or steel. The racquet's grip can be customised with extra layers at the bottom of the handle for added security. Badminton racquets have a cap on their dimensions, which are 680mm in length and 230mm in width. The bottom cap of a racquet can be customised with stickers to add a touch of personality and protect the racquet from wear and tear.

Scoring system
The scoring system in badminton has undergone several changes over the years, with the original system dating back to as early as 1873. The traditional scoring system involves playing the best of three games, with each game played to a certain number of points depending on the players: 15 points for men's singles and doubles, and 11 points for ladies' singles. Alternatively, a single game to 21 points can be played to determine the match. The server is usually decided by a coin toss or by dropping the shuttle on top of the net, with the direction it points determining the server.
In 2002, the International Badminton Federation (later renamed the Badminton World Federation or BWF) experimented with a new scoring system to improve the commercial and broadcasting appeal of the sport. This system shortened games to seven points and decided matches by the best of five games. However, this experiment was abandoned due to similar match times, and a modified traditional scoring system was implemented.
In 2005, the BWF again experimented with the scoring system, aiming to regulate playing time and simplify the system for viewers. This led to the adoption of a new scoring system in 2006, where games are played to 21 points, with players needing to win by a margin of at least two points. There is a 30-point cap to prevent indefinite play, and matches usually follow a best-of-three format. This system was standardised by the BWF, which governs international play.
In 2025, the BWF announced plans to trial a new 3x15 scoring system with a 21-point cap in selected tournaments. This system could potentially replace the current best-of-three format.
It is important to note that the scoring rules in badminton also include regulations for serving and receiving positions. The receiver's position is determined by the server's score, with the receiver standing diagonally opposite the server. Additionally, the serving side is determined by whether the score is even or odd, with players serving from the right court for even scores and the left court for odd scores.

Match format
The match format in badminton depends on the number of entries in each event. If there are two or fewer entries, the event will be cancelled or merged with other events.
Badminton can be played as singles or doubles. In singles, two players compete against each other, whereas in doubles, two pairs of players form teams and compete against each other, resulting in a game of four players. All singles and doubles matches are the best of three games. The first side to 21 points wins a game, with a point being scored on every serve and awarded to whichever side wins the rally. The winning side gets the next serve. If the score reaches 20-20, a side must win by two clear points. If the score reaches 29-29, the first side to reach 30 points wins.
In singles, a badminton court is 13.41m long and 5.18m wide. The width extends to 6.1m in doubles. The net is 1.55m high at the ends and 1.52m high where it dips in the middle. A serve must pass the short service line, which is 1.98m from the net. Beyond this line is another line that runs down the middle to split the left and right service courts. There is also a doubles service line 0.76m in from the baseline. This means each service court is 3.96m long and 2.59m wide.
Tournament formats include single-elimination, double-elimination, and round-robin. Single-elimination, also called knockout or sudden death, is the format seen at most international events. It is straightforward, as the loser of a match is eliminated and the winner advances. However, it guarantees players only one match. In double-elimination, a player must lose twice to be eliminated, guaranteeing two games per player. Winner's/loser's bracket is similar, but a player can only lose their first match. Round-robin involves putting players into different groups, with each player playing one match against every other player in their group. The best performer from each group then advances to the elimination bracket.

Faults
Contact Faults
Contact faults occur when the shuttlecock comes into contact with any object or person other than the player's racket. This includes any part of the body other than the racket, as well as any other objects or people that may be on the court.
Double-Hit Faults
Double-hit faults occur when a player hits the shuttlecock twice in succession. This includes hitting it first to lift it above the net and then smashing it down. However, it is not a fault if the shuttlecock hits the head and the stringed area of the racket in one stroke.
Service Faults
Service faults can occur in several ways. Firstly, if the service is not executed with an upward motion from below the waist, it is considered a fault. Additionally, the server must stand within the diagonally opposite service court without touching the boundary lines. Pausing between the backswing and forward swing when serving is also against the rules and can result in a fault.
Over the Net Faults
If the shuttlecock fails to pass over the net and land inside the opponent's court, it is considered a fault. This includes hitting the shuttlecock into the net, as well as failing to clear the net.
Improper Conduct Faults
Improper conduct faults can occur when a player violates specific court or equipment regulations, or when unsportsmanlike behaviour interrupts the normal flow of the rally. This includes stepping on boundary lines during service, touching the net with the body or racket, obstructing an opponent's shot, or engaging in verbal abuse or intentional delays.

Let calls
In badminton, a 'let' is a redo of a point. It can be called by an umpire or a player (in the absence of an umpire) to halt play. When a let is called, the score does not change, and the same server serves the same receiver. A let is not the same as a fault—in a let situation, no player loses a point, but if a fault is called, a player loses a point.
There are certain rules and conditions that must be met for a let to be called. A let can be called when there are distractions in the court. These distractions can be objects or people like the coaches of the players on the court. If there is any interference from another player or object, a let can be called. Essentially, if anything interrupts the game and prevents it from being played fairly, a let can be called.
A let can also be called when the shuttlecock hits the net on a serve. According to the Laws of Badminton, an umpire can consider a shuttlecock broken if they see the base or tip separated from the feathered part of the shuttlecock. A let can be called if the shuttlecock gets stuck on the net or if it disintegrates in the middle of a match.
In the case of unsighted line judges, an umpire can call a let. If the receiver is not ready when the opponent serves, they should stay still and not move their racket or feet. They can call a let and demand a redo of the point. However, if the receiver attempts to move or hit the shuttle, they will be deemed to have been ready, and no let will be called.

Key shots
Mastering the different types of shots in badminton is essential to excelling at the game. Here are some key shots that every badminton player should know:
Clear Shot
The clear shot is considered one of the most important and basic shots in badminton. It is performed by hitting the shuttlecock high in the air so that it goes deep into the opponent's court, near their baseline. This shot is typically used defensively to give the player more time to get back into position. It can also be used offensively with a flatter trajectory to surprise the opponent. The clear shot can be executed using an overhead or underarm stroke.
Drop Shot
The drop shot is a delicate technique where the shuttlecock is hit just over the net, making it challenging for the opponent to return. It is often used to catch the opponent off guard by disguising the shot to look like a clear or smash initially and then reducing the speed of the follow-through. Drop shots can be varied in speed, with slower drops used against heavier opponents and faster drops employed against shorter or quicker opponents.
Smash
The smash is one of the most powerful shots in badminton and is usually played on the forehand. It involves hitting the shuttlecock at a steep downward angle when it is high in the air. While the smash can be risky as it may cause a loss of balance, it is effective when used at the right moment, such as when the opponent is off-guard or when the shuttlecock is at a high angle.
Net Shot
Net shots are crucial for dominating the front court. They are typically played close to the net and can be used to create opportunities or force the opponent to lift the shuttlecock high or perform a clear shot. The net lift, a type of net shot, involves hitting the shuttlecock high up towards the opponent's baseline. It is a defensive move used when facing strong net play from the opponent.
Drive
The drive is a fast and horizontal shot exchanged across the net to increase the pace of the game. It is played so that the shuttlecock travels parallel to the ground, just over the net, and close to the opponent's body. Drives are typically flat shots and are essential for beginners to learn.

Frequently asked questions
In badminton, 'cap out' refers to a rule that comes into play when a game is tied at 20-20. Instead of the game ending, play continues until a two-point advantage is achieved, e.g. 22-20 or 30-28 cap.
The use of the word 'cap' in this context refers to a limit or maximum. So, when a game reaches 20-20, players are capped out at 20 points and must continue playing until one player gains a two-point advantage.
Yes, the concept of 'cap out' is similar to a 'deuce' in tennis, where players must continue playing until one player gains a two-point advantage after a tie.
