What is the official length of a full badminton court?
Answer
13.4 metres
The official length of a full badminton court is 13.4 metres.
That length applies to both singles and doubles courts. The main difference between the two formats is width: a singles court is narrower, while doubles uses the full width. The court is divided by a net, and boundary lines determine which areas count during different parts of play.
The familiar court dimensions reflect the sport's development as an indoor game requiring precise movement and controlled angles. Players must cover the rear boundary, the front service area, and the side channels while adjusting to the shuttlecock's rapid changes in speed.
A common mistake is to quote 12.2 metres, a dimension associated with other racket sports or informal measurements. Badminton also has different singles and doubles widths, which can cause confusion when people remember only one court measurement. The 13.4-metre length remains the same for both formats.
