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)
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.
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.
- 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.
Touching the net with the body or the racket is illegal and will result in the loss of the serve or a point awarded to the serving team. Only one hit is allowed per side. If the shuttle hits or goes over the top of the basketball backboard (when they are in their put away position), it will be considered out of bounds.

With laws of badminton dictating specific rules for service in badminton, the court has two service lines, the short service line, which is 1.98m (6.5 feet) from the net, and long service line 0.72m (2.36 feet) in from the baseline, specifically marked for this purpose.
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.
