Badminton Court Regulation Standards

what is a regulation badminton court

Badminton is a racquet sport that involves hitting a shuttlecock back and forth over a net. The game is played on a rectangular court that is divided into halves by the net, with each half further subdivided into four quadrants. The full width of the court is 6.1 metres (20 feet), and the full length is 13.4 metres (44 feet). The service courts are marked by a centre line, a short service line, and the outer side and back boundaries. The dimensions of the court are important to know, as they determine the positioning of the players during the game.

Court dimensions: 20 x 44 feet

A regulation badminton court is rectangular and divided into halves by a net. The full width of the court is 6.1 metres or 20 feet, and the full length is 13.4 metres or 44 feet. The service courts are marked by a centre line dividing the width of the court, by a short service line at a distance of 1.98 metres (6 feet 6 inches) from the net, and by the outer side and back boundaries. The doubles court is wider than the singles court, but both are of the same length. The exception is that the doubles court has a shorter serve-length dimension.

In singles play, the width of the court is reduced to 5.18 metres or 17 feet. The minimum height for the ceiling above the court is not mentioned in the Laws of Badminton. However, a badminton court will not be suitable if the ceiling is likely to be hit on a high serve.

The server and receiver must stand at diagonally opposite sides of the net without touching the boundary lines of their respective service courts. The service is always delivered diagonally across the court, whether in singles or doubles play. When the server's score is even, they serve from the right service court; when odd, they serve from the left service court. The receiver will stand in the service court that is diagonally opposite to that of the server.

The serve must be made underhand, with the racket's head below the server's hand and waist. The shuttlecock must pass over the short service line on the opponents' court or it will count as a fault.

Service rules: Serve diagonally across the court

Serving diagonally across the court is a fundamental part of badminton. This rule applies whether you are playing singles or doubles. The server and receiver must stand on diagonally opposite sides of the court, without touching the boundary lines, until the server strikes the shuttlecock. The other two players may stand wherever they wish, as long as they do not block the vision of the server or receiver.

The server's position depends on their score. If the server's score is even, they serve from the right service court. If their score is odd, they serve from the left service court. For example, if the server has scored 0 points, the score is even, so they serve from the right. If they have scored 1 point, the score is odd, so they serve from the left. The receiver must stand in the opposite service court to the server.

The serve must be made underhand, with the racket's head below the server's hand, and below the waist. An overarm serve is against the rules and would be considered a fault. The whole shuttlecock must also be below 1.15 metres from the surface of the court when struck by the server's racket.

If the shuttlecock hits the net during a serve and falls into the proper service court, a 'let' is called, and the serve is retaken.

Scoring system: First to 21 points wins

The scoring system in badminton is straightforward: the first player or team to reach 21 points wins the game. However, they must lead by at least two points; if the score reaches 20-20, the game continues until one player gains a two-point advantage. This is known as the '21x2' rule. If the match reaches a third game, players change ends when the leading player or team reaches 11 points.

In the event of a tie at one game each, a third game is played to 15 points, again with the same two-point lead rule. The player or team that wins two games out of three is the winner of the match.

A point is awarded to the player or team that wins a rally. The server always starts a rally, and if they win the rally, they score a point and serve again from the alternate service court. If the receiver wins the rally, they score a point and become the new server.

The service court depends on the server's score. When the server's score is even, they serve from the right service court. When the score is odd, the serve is from the left service court.

Ceiling height: No minimum, but not too low

While there is no minimum ceiling height mentioned in the Laws of Badminton, it is important to ensure that the ceiling is not too low. The shuttlecock, which is a feathered or plastic projectile, should not hit the ceiling during a serve or at any point during gameplay. Therefore, the ceiling height should allow for sufficient clearance to accommodate the trajectory of the shuttlecock, especially during high serves.

The absence of a specified minimum ceiling height in the rules provides flexibility for badminton courts to be set up in various locations. This adaptability allows the sport to be played in diverse settings, ranging from recreational outdoor spaces to professional indoor arenas.

It is worth noting that while there is no prescribed minimum ceiling height, the height of the net separating the two courts is standardized. This net plays a crucial role in defining the dimensions of the court and ensuring fair gameplay.

When considering ceiling height, it is essential to strike a balance. While a higher ceiling is preferable to avoid interference with the shuttlecock's trajectory, an excessively high ceiling may pose challenges in terms of lighting and visibility for players. Therefore, the ideal ceiling height should provide adequate clearance without compromising the overall playing environment.

In conclusion, while there is no minimum ceiling height mandated by the regulations, it is important to ensure that the ceiling is not so low that it interferes with the game. This consideration ensures that players can fully enjoy the fast-paced and dynamic nature of badminton without the constraint of a low ceiling impeding their shots or affecting the natural flight path of the shuttlecock during play.

Shuttlecock: Hit the base, not feathers

A regulation badminton court is a rectangular space measuring 6.1 metres (20 feet) wide and 13.4 metres (44 feet) long. The net that divides the court in half sits at a height suitable for high serves—the minimum ceiling height above the court is not specified in the Laws of Badminton. The full width of the court is only used in doubles matches; in singles matches, the width is reduced to 5.18 metres (17 feet). The service courts are marked by a centre line dividing the width of the court, by a short service line at a distance of 1.98 metres (6 feet 6 inches) from the net, and by the outer side and back boundaries.

Now, onto the shuttlecock. The shuttlecock is a projectile made of feathers or plastic, with a rubber base. It is important to hit the base of the shuttlecock, not the feathers. This is because the feathers are there to stabilise the flight of the shuttlecock, not to be hit. Hitting the feathers will result in an unpredictable shot, and may damage the shuttlecock. To hit the base, the player must make contact with the shuttlecock at the right point—below the waist for a serve, and probably around waist height for a return shot.

The shuttlecock is a key part of the game of badminton. Points are scored by striking it with a racquet and landing it within the other team's half of the court, within the set boundaries. Each side may only strike the shuttlecock once before it passes over the net. Play ends once the shuttlecock has struck the floor or ground, or if a fault has been called by the umpire, service judge, or (in their absence) the opposing side.

The serve is a key skill in badminton. The serve must be made underhand, with the racket's head below the server's hand, and the whole shuttle must be below 1.15 metres from the surface of the court at the instant it is hit. The serve is delivered diagonally across the court, with the server and receiver standing at diagonally opposite ends of the court without touching the boundary lines. If the shuttlecock hits the net during a serve and falls into the proper service court, a let is called, and the serve is retaken.

Badminton matches are typically played as a ''best of three' format. In each game, the player or pair who reaches 21 points first wins, provided they have a two-point lead over their opponent. If the score reaches 20-20, the game continues until one player or pair gains a two-point lead.
