The boundaries (line settings) of badminton singles and doubles are different, mainly in the following aspects:
1.Service Boundary:
Singles: The service line is parallel to the bottom line, about 198 m (6 ft 6 in).
Doubles: The service line is parallel to the bottom line, about 1 from the bottom line98 m (6 ft 6 in), but in doubles, there is another line parallel to the bottom line on each side, about 05 m (1 ft 8 in), this line is called the "front boundary".
2.Bottom Line:
Singles and doubles have the same baseline width, both at a distance of 0375 m (1 ft 2.)25 inches).
3.Area in front of the net:
Singles: The area in front of the net has only the area between the two posts.
Doubles: The area in front of the net has an area between the four posts because the distance between the posts is narrower when playing doubles.
4.Singles and doubles court sizes:
The singles court length is 134 m (44 ft) and a width of 518 m (17 ft).
The doubles court length is 134 m (44 ft), but 6 in width1 m (20 ft).
When playing badminton matches, both players and referees need to clearly identify these boundaries to ensure the fairness and accuracy of the game.
