Court dimensions 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.
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.
So just to be clear, a doubles service court is made from these four lines: The centre line. A doubles side line (outside side line) The front service line. The inside back line (not the very back line, but the next one in)
The doubles service line is marked out 76cm (2.5ft) from the baseline. The doubles back service line runs parallel to the baseline and like the baseline, runs the full width of the court.
Boundary lines is a part of the badminton court. Outdoor badminton field should be rectangle measuring 5,18 m x 13,40 m for single competition and 6,10 m x 13,40 m for doubles. Boundary lines are adjustable for single and double play with maximum dimensions of 6,10 m x 13,40 m.
- A legal doubles serve would land in the area bounded by the center line, the doubles long service line, the doubles side line and the short service line (short and wide). - Once the serve is made in doubles, the court area is bounded by the doubles sideline and the back boundary line.
Each doubles service court is bounded by the short service line, the centerline, the doubles sideline, and the doubles back service line. Its dimensions are 13 feet (3.96 m) long by 10 feet (3.05 m) wide. It is sometimes referred to as short and . The side alley is in bounds; the back alley is not.
The two short lines bracket the doubles back service line, roughly equivalent to a distance of between 12.4 meters to 12.9 meters from the basline of the opposite end. The reason for the standard is to ensure advanced players can use a suitable shuttle speed to hit from baseline to baseline.
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.
