Badminton is a fast-paced sport that requires a team of officials to ensure fair play. The line judge is one such official, responsible for monitoring the service, sidelines, and baseline during a match. Their main duty is to impartially and accurately decide and announce, through verbal calls and hand signals, whether the shuttle has landed inside or outside the boundary lines. The number of line judges varies depending on the level of the tournament, with major tournaments having one line judge for each line, and less important tournaments having judges responsible for two or more lines.

Calling 'in' or 'out'
The main responsibility of a line judge in badminton is to indicate whether a shuttlecock has landed inside or outside the boundary lines, i.e. calling 'in' or 'out'. Line judges are assigned to specific lines and are responsible for making calls on those lines. This includes monitoring the service, sidelines, and baseline during a match. In other words, they are responsible for calling service faults and line errors.
Line judges need to have a good understanding of the game and its rules to make accurate calls. They must also be able to communicate their calls clearly to the umpire and players. This is typically done through verbal calls and hand signals. For example, if a shuttlecock lands near the line, the line judge must decide whether it is 'in' or 'out' and signal this to the umpire, who will then make the final decision.
The number of line judges in a badminton match can vary depending on the level of the tournament and the type of match. In most major tournaments, there can be up to ten line judges assigned to a court for a particular match. For individual singles matches, there are typically four line judges, two for each side of the court positioned at the baseline. For doubles matches, there are typically eight officials, including six line judges, with two additional line judges sometimes added, one for each side of the doubles service line.
Becoming a line judge in badminton requires training and experience. The process of becoming a line judge varies by country. For example, in England, the Badminton Line Judges Association of England manages the training, while in the US, it is handled by USA Badminton. To become a national line judge, one must complete the required training and gain experience at a national or continental level. To become a Badminton World Federation (BWF) line judge, one must be endorsed by their national or continental confederation and meet certain criteria, including prior experience officiating at a national or continental level.

Monitoring sidelines, baselines and service
Line judges in badminton are responsible for monitoring the sidelines, baselines, and service lines, making critical calls on whether the shuttlecock lands inside or outside the boundary lines. They are tasked with closely observing their assigned lines to determine if a shuttlecock lands "in" or "out", requiring sharp eyesight and quick reflexes.
In a badminton match, the sidelines, baselines, and service lines play a crucial role in defining the playing area and determining the legality of shots. The sidelines delineate the width of the court, extending from the baseline at the back of the court to the front, forming a rectangular playing area. The baselines, located at the back of the court on each side, define the depth of the playing area. Meanwhile, the service lines are positioned within the court, parallel to the net, and play a vital role in determining the validity of serves.
Line judges are positioned strategically to monitor these lines effectively. For singles matches, there are typically four line judges, with two judges assigned to each side of the court, positioned at the baseline. This placement allows them to observe the sidelines and baseline simultaneously, ensuring that any shots landing near these lines are accurately judged. For doubles matches, additional line judges may be introduced, positioned at the doubles service line, to accommodate the expanded court dimensions and ensure accurate calls.
The role of line judges in monitoring the sidelines, baselines, and service lines is critical to ensuring fair play and accurate scoring in badminton. Their decisions directly impact the outcome of a rally and, consequently, the overall match. Line judges must remain vigilant and focused throughout the match, as even slight errors in judgment can significantly influence the game.
To make their calls, line judges use both verbal announcements and standardised hand signals to indicate whether a shuttlecock is "in" or "out". These signals are crucial for communicating their judgments to the players, the umpire, and other officials clearly and promptly. While line judges have the responsibility to make these calls, their decisions can be appealed by players, with the umpire providing the final ruling on protested calls.

Hand signals and verbal calls
Line judges are responsible for monitoring the service, sidelines, and baseline during a badminton match. They must decide and announce whether the shuttlecock lands inside or outside the boundary lines, using both verbal calls and hand signals.
Verbal calls are straightforward, with the line judge calling "in" or "out" to indicate whether the shuttlecock has landed inside or outside the boundary lines.
As for hand signals, the line judge will use their right hand to indicate "in" or "out" by pointing their fingers downwards towards the floor for "in" and waving their hand horizontally for "out". The hand signals are important as they provide a clear and unambiguous indication of the line judge's decision, which can be seen by the players, the umpire, and other officials.
In addition to the basic "in" or "out" calls, line judges may also use hand signals to indicate specific situations or requests. For example, a line judge may signal for a player to serve, indicating that the server has committed a fault, or request for the rally to be stopped if there is an injury or interference.
It is important for line judges to be consistent and accurate in their hand signals and verbal calls to ensure the fair play of the game. Their calls can be appealed by the players, and the umpire will then provide a final ruling on the protested call.

Number of line judges per match
The number of line judges in a badminton match varies depending on the level and type of tournament. According to the Badminton World Federation (BWF), there are usually ten line judges assigned to a court for a particular match, each with their respective lines to monitor. However, there can be fewer line judges, depending on the level of play. For example, in individual singles matches, there should be a total of four line judges, with two on each side of the court positioned at the baseline. In doubles matches, there are typically six to eight officials, including the umpire and service judge, and sometimes an additional two line judges are added for the doubles service line.
The role of a line judge in badminton is crucial to the progress and flow of a match. They are responsible for making calls on whether the shuttlecock has landed inside or outside the boundary lines, indicating "in" or "out". Line judges are also responsible for monitoring the service, sidelines, and baseline during a match. Their calls are essential, as without them, umpires may become confused, and the game may devolve into chaos without an instant review system.
To become a line judge, one must gain experience in serving as a line judge in national or local matches. Their performance will be assessed by the national association, which can then submit their name to the overseeing Continental Confederation for nomination. At the national level, aspiring line judges must pass a certification assessment to ensure they are fit to make crucial line calls.
Line judges are considered technical officials, and the BWF places great emphasis on ensuring they have everything they need to perform their roles effectively. This includes providing courtside chairs, snacks, and other amenities. Serving as a line judge in a BWF tournament is considered an honour, and BWF-certified line judges serve four-year terms, which can be renewed.
