What is badminton?

Badminton is a type of racket sport in which two players (single) or two teams (double) play using a racket and shuttlecock on a square court with a net installed. Both players or both teams will rally by hitting the shuttlecock with each other’s court, and the point will end as soon as the shuttlecock falls to the ground. If the shuttlecock falls into your court or if the hit shuttlecock falls outside the opponent’s court, you lose a point, and if the shuttlecock falls into the opponent’s court or if the hit shuttlecock falls outside your court, you score.


The shuttlecock (or shuttle) is cone-shaped with feathers on a leather-covered cork and has a completely different flight trajectory from the usual balls used in other racquet sports due to its special aerodynamic nature. The shuttlecock’s top flight speed is much faster than that of other racquet sports, but its flight speed decreases more rapidly than that of regular balls because it receives a lot of air resistance. The shuttlecock is heavily influenced by the wind, so all official badminton games are held indoors. However, everyday games for play purposes are sometimes played outdoors.

Badminton has been adopted as an official Olympic sport since the 1992 Summer Olympics. The Olympic badminton event consists of five events: single and double each for women and men, and mixed doubles. Strong endurance, agility, muscle strength, speed, and accuracy are required in the competition of professional players. In addition, badminton is a very technical sport in that it also requires balanced movement and the technique of using a racket.

Court Standard

The court is a rectangular space with a net in the center. In general, both single and doubles lines are drawn and double coats are wider in the net direction than singles coats and have the same length. However, in the case of doubles, the length of the service line is shorter than that of fasting, which is also a part that beginners often cause confusion about.

The overall width of the court is 6.1 meters (20 feet) and the width of the single court is 5.18 meters (17 feet). The overall length of the court is 13.4 meters (44 feet).

The service court is indicated by a center line that bisects the court in a direction perpendicular to the net, a short service line that is 1.98 meters (6 feet) away from the net, and an outer line of the court. In doubles, a long service line 0.78 meters (2 feet) away from the back line of the court is used.

The net is 1.55 meters (5 feet) high at both ends and 1.524 meters (5 feet) high at the center. The net post is set on the doubles sideline, which is the same for singles matches.

The minimum ceiling height for the World Badminton Federation (BWF) events, including the Olympic Games, the World Mixed Team Championships, the World Individual Championships, the World Team Championships, and the World Junior Championships, is more than 12 meters (39 feet). In international competitions other than the aforementioned competitions, the ceiling height shall be 12 meters (39 feet) in principle, but shall be at least 9 meters (30 feet).
