Shuttlecock weight

As per the BWF (Badminton world federation guidelines) the standard weight of a feathered badminton shuttlecock should range from 4.74 to 5.50 grams.
On the other hand, a synthetic shuttlecock used by recreational players that weighs with a +/-10 percent variation is acceptable.

This specification is for the feathered shuttlecock that is used in tournament match play. Feather shuttles have 16 feathers fixed at the cork base.

The feathers which make the badminton shuttlecock so light-weight should have a uniform length between 62 mm to 70 mm when measured from the top of the base to the tip.

The upper diameter, defined by the tip of the feathers ranges from 58 mm to 68 mm.
The lower diameter, of the cork base, ranges from 25 mm to 28 mm, and the base has to be rounded at the bottom.
Feathers of the shuttlecock are fastened firmly to each other with threads or other suitable materials.

The standard specifications for a synthetic (non-feathered) badminton shuttlecock are also same, except that due to differences in material being used, a 10 percent variation is acceptable.
