The service courts area unit marked by a centre line dividing the dimension of the court, by a brief baseline at a distance of one.98 metres (6 linear unit six inch) from internet, and by the outer aspect and back boundaries. In doubles, the service court is additionally marked by a protracted line, which is 0.76 metres (2 linear unit six inch) from the rear boundary.

If the receiver is not ready when the service is delivered, a let shall be called; yet, if the receiver attempts to return the shuttlecock, the receiver shall be judged to have been ready.

Equipment

Racquets

Badminton racquets square measure light-weight, with high-quality racquets deliberation between seventy and ninety five grams (2.5 and 3.4 ounces) not together with grip or strings.[14][15] they're composed of the many totally different materials ranging from carbon fibre composite (graphite strengthened plastic) to solid steel, which can be increased by a spread of materials. Carbon fibre has a wonderful strength to weight magnitude relation, is stiff, and offers glorious K.E. transfer. Before the adoption of carbon fibre composite, racquets were made from light-weight metals like aluminum. Earlier still, racquets were made of wood. Cheap racquets square measure still typically made from metals like steel, however picket racquets are not any longer factory-made for the normal market, because of their excessive mass and cost. Nowadays, nanomaterials like carbon nanotubes and carbon square measure added  to racquets giving them larger sturdiness.[citation needed]

There is a good sort of racket styles, though the laws limit the racket size and form. Different racquets have enjoying characteristics that attractiveness to totally different players. The traditional oval head form remains offered, however Associate in Nursing isometric head form is more and more common in new racquets.

Strings

Thicker strings ar additional sturdy, however several players like the texture of diluent strings. String tension is often within the vary of eighty to one hundred sixty N (18 to thirty six lbf). Recreational players typically string at lower tensions than professionals, generally between eighty and a hundred and ten N (18 and twenty five lbf). Professionals string between regarding a hundred and ten and one hundred sixty N (25 and thirty six lbf). Some string makers live the thickness of their strings below tension in order that they are literally thicker than given once slack. Ashaway Micropower is really zero.7mm however Yonex BG-66 is regarding zero.72mm.

shuttlecock

A shuttlecock (often abbreviated to shuttle; conjointly known as a birdie) may be a high-drag projectile, with Associate in Nursing open round shape shape: the cone is made from sixteen overlapping feathers embedded into a rounded cork base. The cork is roofed with skinny animal skin or artificial material. Synthetic shuttles area unit typically employed by recreational players to cut back their prices as feathered shuttles break simply.

Players ought to conjointly make sure that they learn safe and correct footwork, with the knee and foot in alignment on all lunges. This is quite simply a security concern: correct footwork is additionally vital so as to maneuver effectively round the court.
