Net. 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.
Games can be played as a doubles format with four players, or singles between two players. The court boundaries for doubles and singles are different. In singles the court is thinner, with the wide, outside 'tramlines' out of bounds. In doubles the court is full width and these tramlines are now 'in'.
The lines surrounding the court is called the BOUNDARY LINE. When the shuttlecock hits out of the line, the point is given to the receiver. There are 2 types of boundary line; the serving line,and the boundary line. The point is given to the hitter if the shuttlecock lands right at the line.
A singles service court is a box made from four lines: The centre line. A singles side line (inside side line) The front service line. The back line (the outside one, all the way at the back)
In singles the court is thinner, with the wide, outside 'tramlines' out of bounds. In doubles the court is full width and these tramlines are now 'in'. During service in doubles, the court is short, with the rear 'tramlines'at the back of the court, being out of bounds until the serve is returned.
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 outer sidelines are sometimes referred to as “outer tramlines” or “doubles sidelines”. On a regulation badminton court, the outer sidelines will run the full 13.41m /44.00ft length of the court. The outer sidelines are marked 5.18m (17.00ft) apart and run parallel to one another.
Baseline: It is basically the back line at the boundary that is parallel to both the ends of the net. The length of baseline is typically the overall width of the court.
Alley- An extension of the width of the court by 1'6” on both sides to be used in doubles play. Back alley- Are between the doubles back service line and the singles back service line.
