What is the maximum overall length of a badminton racket under BWF regulations?

The maximum overall length of a badminton racket under BWF regulations is 680 millimetres.

A badminton racket is a lightweight frame-and-shaft implement designed for rapid swings, precise control and varied shot production. The regulation limit covers the racket’s complete length, from the handle to the farthest point of the head. Manufacturers can therefore design different head shapes and balance points while remaining inside the permitted dimensions.

The racket’s maximum width is also regulated, and the stringed area must fit within the racket head. These restrictions keep equipment broadly comparable and prevent unusually large frames from changing the nature of the sport. Modern rackets are commonly made from graphite or other composite materials rather than the wood used in many older rackets.

The 680-millimetre figure is a maximum, not a required standard length. Players may use rackets shorter than that limit, and junior equipment can be smaller. It should also not be confused with shuttlecock dimensions or the length of the court.
