A badminton court is a rectangle 13.4-metres long and 5.18-metres wide for singles, extended on each side with 42-centimetre alleys for doubles (making the doubles court 13.4m x 6.1m). It is divided into two equal sections by the net, 155cm high at the posts at either side and dipping to 152.4cm in the centre.
The shuttle consists of a rounded cork base covered in a thin layer of leather. Sixteen goose feathers are attached to this base. Each shuttle requires three birds because a wing has six feathers and manufacturers cannot mix those from left and right wings, because they have different curvatures. Most high-quality shuttles tend to use feathers from the left wing of the bird, considered stronger. Note: all the feathers come from birds that have been raised for food.
The length of the shuttle may vary between 64 to 70 millimetres, provided that all feathers are equal length. Each shuttle should weigh between 4.74 and 5.5 grams.
A badminton racquet may be up to 68cm long and 23cm wide, with a head up to 29cm long.
