The badminton court is 13.4m long and 6.1m wide. For singles the court is marked 5.18m wide.
The lines marking out the court are easily distinguishable and coloured white or yellow. The lines are 40mm wide.
A court may be marked out for singles only. The back boundary lines also become the long service lines and the posts or the strips of material representing them are placed on the side lines.
The diagonal full length of the full court is 14.366m.
The posts are 1.55m high from the surface of the court and remain vertical when the net is strained.
The posts are placed on the double side lines irrespective of whether singles or doubles is played. The posts or supports must not extend into the court beyond the side lines.
Where it is not practicable to have posts on the side lines, some method can be used to indicate the position of the side lines where they pass under the net, eg by the use of thin posts or strips of material 40mm wide, fixed to the side lines and rising vertically to the net cord.
The net is 760mm in depth and a minimum of 6.1m wide.
The top of the net from the surface of the court is 1.524m at the centre of the court and 1.55m over the side lines for doubles.
There must be no gaps between the ends of the net and the posts. If necessary, the full depth of the net at the ends is tied to the posts.
