Sending the shuttle over the net gets regulated by badminton serving rules. The rules of badminton serving are exact - yet often misunderstood by players.
SERVICE RULES BADMINTON: Three visible badminton court lines get used during the serve. The lines only apply to the specific rules for serving in badminton games.
Like a serve in the rules of tennis they are not actually related to the individual rallies.
Sending the shuttlecock over the net and towards the receiver starts a rally.
There are some special restrictions on the badminton serve. The aim is to avert the server from winning an unfair advantage.
One example: In a doubles match only one receiver returns the serve back over the net. Unlike a tennis game, the server must use an underarm hitting style to send the shuttle upwards and over the net.
In fact, the rules and regulations of badminton are clear on the technique for serving. The server must strike the shuttle around the same level as their lower rib cage. You could simplify this definition as a height below the waist but above the shorts.
Each opponent has two service boxes within the singles court. One back box is for the left service and the other for the right service court.
The same is true for a doubles game. But, the service boxes are wider and the doubles back line makes them a little shorter in length.
A service box in badminton is only used during a serve. Each player must serve from inside the box markings.
They serve over the net to the receiver. He will receive the serve from inside his 'diagonally' opposed service box.
The shuttle should travel in a diagonal direction across the playing area. The flight should be towards the opponent's service court back box.
If the birdie touches the ground outside the box lines then the server wins the serve. Players must be inside their own service box until the receiver strikes the shuttle.
BWF official badminton rules govern competitive events and tournaments. The regulations allows five different formatted types of male and female opponents.
In most cases, badminton gets played as an indoor court game. Its competitors will be either two single players (singles) or two pairs of players (doubles).
The rules for badminton doubles have slight variances to the singles matches. For example, a game of doubles would have four players - two against two. Either of the paired players may take the shot in the rallies, following the initial serve. So, taking turns is not required.
