Badminton is a fast-paced sport that requires a team of officials to ensure fair play. While there is no standard number, the number of line judges in a badminton match can vary depending on the level of the tournament. Typically, there can be up to 10 line judges assigned to a court for a match, with two judges each for the back lines and side lines. Line judges play a crucial role in indicating whether the shuttlecock has landed in or out, especially when it lands near the lines they are assigned to monitor. Their role is essential to maintaining the accuracy and integrity of the game.

Number of line judges varies by tournament level
The number of line judges in a badminton match varies depending on the level of the tournament. For instance, there can be as many as 10 line judges assigned to a court for a particular match, depending on the tournament level. The Badminton World Federation (BWF) deploys a pool of over 100 international line judges for major events such as the BWF World Championships, Sudirman Cup, Thomas & Uber Cups, and multi-sport events like the Olympic Games.
The process of becoming a line judge varies across countries. In China, for instance, there are rigorous levels for line judges and umpires, requiring extensive classes, tests, and experience. In contrast, some countries may resort to using local players as line judges for regular games, reserving accredited judges for high-profile matches or the main court.
To become an international umpire, aspiring individuals must apply to the BWF for selection to officiate at international tournaments. The BWF provides training that surpasses the national level, and successful completion results in becoming a BWF umpire.
The number of line judges can vary even within the same tournament. For example, in BWF Germany, there are typically four line judges, with two assigned to the back lines and two to the sides. However, there may be more line judges in the later rounds.

Line judges' hand signals
The number of line judges in badminton can vary depending on the level of the tournament. There may be up to 10 line judges assigned to a court for a match, and the Badminton World Federation (BWF) has a pool of over 100 international line judges who officiate at major events.
Line judges are responsible for indicating whether a shuttlecock lands "in" or "out" when it falls near the lines they are assigned to monitor. They use various hand signals to communicate their calls to the players and the umpire. Here are some of the standard hand signals used by line judges in badminton:
- Service Fault: One of the most common faults in badminton is a service fault. If the line judge notices a service fault, they will open their right hand and gently touch the palm with their left hand. This signal indicates that the player failed to hit the bottom of the shuttlecock properly, as per rule 9.1.4.
- Player Obstruction: In some instances, a player's body or other unavoidable factors may obstruct the line judge's view, preventing them from seeing whether the shuttlecock landed in or out. In such cases, the line judge should cover their eyes with their hands to indicate to the umpire that they could not make a clear judgement.
- Foot Fault: According to rule 9.1.2, players must not step on the service court boundary line, and their feet must be at least partially touching the ground during the serve (rule 9.1.3). When a player commits a foot fault, the line judge will stretch out their right leg and signal a fault with their right hand, indicating that the player's feet were off the ground or on the boundary line.
It is important for players and spectators to familiarise themselves with these hand signals to understand the calls made during a badminton match. Line judging requires a high level of concentration and quick decision-making due to the fast-paced nature of the sport.

Line judges' criteria and selection
The number of line judges in badminton depends on the level of the tournament. While there can be as many as 10 line judges assigned to a court for a particular match, there is usually a need for more manpower in some locations. In such cases, local players or even first-year university students may be called upon to fill in as line judges for regular games, while accredited line judges are assigned to the main court and high-profile games.
Line judges are responsible for indicating whether a shuttle has landed "in" or "out" when it lands near the lines they have been assigned to monitor. This requires intense focus as badminton is the fastest racket sport in the world.
To become an accredited line judge, one must meet certain criteria and undergo a selection process. The Badminton World Federation (BWF) requires its line judges to have prior experience officiating at the national or continental level. They must be nominated by their respective continental confederation, ensuring appropriate regional representation at events.
In addition to experience, aspiring line judges may need to pass a test and participate in an interview, where they are assessed on their technical knowledge and experience. This process ensures that line judges possess the necessary skills and knowledge to make accurate calls during matches.

Line judges' positioning
Line judges in badminton play a crucial role in the progress and flow of a match. They are responsible for indicating whether a shuttlecock has landed "in" or "out" and communicating this to the umpire, who then decides whether to award a point or not. They also make calls on the legality of a service, depending on where the shuttlecock falls.
The number of line judges in badminton can vary depending on the level of the tournament. There may be up to 10 line judges assigned to a court for a match, and the Badminton World Federation (BWF) has a pool of over 100 international line judges for major events.
Line judges are positioned at a distance of 2.5 to 3.5 meters from their respective boundary lines, ensuring they have a clear view of the service line or boundary line they are assigned to monitor. They are positioned just behind the service judge, who is responsible for overseeing the service area and receiving areas.
The specific positions of line judges can vary depending on the court and the tournament. However, their primary focus remains on the shuttlecock, and their calls are based on its landing position. Line judges must maintain their focus on the shuttlecock at all times, as even a momentary lapse in judgment can delay a match.
Becoming a line judge requires dedication and a thorough understanding of the rules. In some countries, there are different levels and rankings for line judges, with advancement requiring extensive training, classes, tests, and experience.

Line judges' duties
Line judges are integral to the success of a badminton match. Their primary duty is to make impartial and accurate "in" or "out" calls when the shuttle lands near the lines they are assigned to monitor. This involves a high level of concentration as badminton is a fast-paced sport with the shuttle moving at high speeds. Depending on the level of the tournament, there can be up to 10 line judges assigned to a court for a particular match. For instance, individual singles matches require a total of six officials: an umpire, four line judges (two for each side of the court at the baseline), and sometimes two additional line judges for doubles matches.
Line judges are usually assigned to watch a single path of a line on the court, such as the baseline or sideline. The length of the line they monitor may vary depending on the number of judges available per court. Their role is crucial as it directly impacts the scoring of the game. A point is scored when the shuttlecock lands inside the opponent's court, and a player loses a point if the shuttlecock hits the net or lands outside the court.
The pathway to becoming a line judge varies across different regions. In some countries, aspiring line judges must undergo extensive training, including classes and tests, and gain experience at the national or continental level before being considered for major events. For example, in China, there are multiple levels of certification for line judges, with the highest levels being highly respected within the badminton community.
In other cases, local players or individuals with a passion for the sport may be invited to fill in as line judges when there is a shortage of manpower. However, even in such cases, some level of training or familiarity with the rules of the sport is expected to ensure fair and accurate judgments.
Line judges are an essential component of the technical officials in badminton, working alongside umpires and referees to ensure the smooth and fair conduct of the game. Their specific duties of monitoring the shuttlecock's landing position and making timely "in" or "out" calls contribute significantly to the overall success of a badminton match.
