Text / VICTOR BADMINTON A-Z Editorial Room

Badminton has a long history, originating from the game of battledore and shuttlecock. A sport similar to modern badminton appeared in western India in the mid-19h Century. The British loved this sport and took it back to the UK.

Due to the lack of a clear set of rules there were often disputes amongst players, that was until Bath Badminton Club completed the first badminton rule book in 1887. When the English Badminton Association was established in 1893 the rules were revised and unified and have since been the main basis for the sport.

Of course, people who play badminton should understand what the judges' hand signal mean. Below we will explain eight hand signals often used by the service judge and line judges in badminton competitions

Introduction to service judge hand signals

Service fault is one of the most common faults seen in badminton, so, in international competitions, as well as an umpire and six line judges, there will also be a service judge who will sit opposite the umpire and will judge if a player's service action is in accordance with the rules. Below, we will introduce the hand signals for five commonly seen service faults.

1. Undue delay of serve

BWF rule 9.1.1 states "Neither side shall cause undue delay to the delivery of the service once the server and the receiver are ready for the service. " After a player finishes raising their racket head backwards any delay is undue delay of serve.

Also, rules 9.1.7 and 9.2 tell us that, once a player begins to swing his/her racket forward, the service is deemed to have begun and the racket must continue moving forward in a continuous motion until the serving action is completed, otherwise a fault will be called--for non-continuous movement.

When undue delays occur the service judge will swing their right arm to the left to indicate that a player has been penalized for undue delay.

Line judge hand signals

As well as the service judge there are also line judges for the back lines and side lines. A line judge should be seated 2.5-3.5m from the line and judges whether a shuttlecock lands "in" or "out", deciding whether a player has scored a point.

Below the three most common hand signals are explained

Every should spend some time becoming familiar with the commonly seen judges' hand signal so that whether you are watching a match or playing in one you won't have to ask "What is happening now?" "What kind of fault did the judge just signal?" and avoid other situations in which you aren't sure what is going on!
