What are laws of the badminton?

Answer 1

Playing court dimensions

Badminton court, isometric view

The court is rectangular and divided into halves by a net. Courts are usually marked for both singles and doubles play, although the laws permit a court to be marked for singles only. The doubles court is wider than the singles court, but both are the same length. The exception, which often causes confusion to newer players, is that the doubles court has a shorter serve-length dimension.

The full width of the court is 6.1 metres (20 ft), and in singles this width is reduced to 5.18 metres (17 ft). The full length of the court is 13.4 metres (44 ft). 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 (6.5 ft) from the net, and by the outer side and back boundaries. In doubles, the service court is also marked by a long service line, which is 0.78 metres (2 ft 6 inch) from the back boundary.

The net is 1.55 metres (5 ft 1 inch) high at the edges and 1.524 metres (5 ft) high in the centre. The net posts are placed over the doubles sidelines, even when singles is played.

There is no mention in the Laws of Badminton of a minimum height for the ceiling above the court. Nonetheless, a badminton court will not be suitable if the ceiling is likely to be hit on a high serve.

Equipment laws

The Laws specify which equipment may be used. In particular, the Laws restrict the design and size of racquets and shuttlecocks. The Laws also provide for testing a shuttlecock for the correct speed:

3.1 To test a shuttlecock, use a full underhand stroke which makes contact with the shuttlecock over the back boundary line. The shuttlecock shall be hit at an upward angle and in a direction parallel to the side lines. 3.2 A shuttlecock of the correct speed will land not less than 530 mm and not more than 990 mm short of the other back boundary line.
