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.
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.
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 outermost lines form the doubles court. So in a doubles rally, the shuttle is allowed to land anywhere on the court. The singles court is slightly narrower than the doubles court. The singles side lines are not the outermost lines, but the next ones in.
For Doubles: During service, the left & right side boundaries are considered as valid. While, the back boundaries are considered as invalid. However, during game play the complete court is considered as valid.
- 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.
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.

Baseline: This indicates the boundary of the court lengthwise. When a player is serving, they must stand behind this line. Also, if a player hits a shot that lands past the baseline, it is considered “out,” and that player loses the point. Doubles Line: This line is only relevant during doubles matches.
