# Law 2: Shuttle (BWF Laws of Badminton)

Badminton · Law 2: Shuttle · Insporta Book (https://book.insporta.app/badminton/laws/law-2-shuttle/)

What a shuttle is made of, the feathered shuttle's feathers, base and weight, synthetic shuttles, and shuttles adapted to altitude or climate.

## 2.21 The Feathered Shuttle

Sixteen feathers, their length and tip circle, the cork base and the weight.

### Test 1: The feathered shuttle: feathers, base and weight

- A feathered shuttle has 16 feathers fixed in the base. (Source: BWF Laws 2027, Law 2.2.1)
- The feathers have a uniform length between 62 and 70 mm; 58-68 mm is the circle of the tips. (Source: BWF Laws 2027, Law 2.2.2)
- A shuttle weighs from 4.74 to 5.50 grams. (Source: BWF Laws 2027, Law 2.2.6)
- The base is 25 to 28 mm across. (Source: BWF Laws 2027, Law 2.2.5)
- The base is rounded on the bottom. (Source: BWF Laws 2027, Law 2.2.5)
- Each length is inside 62-70 mm, but the Law asks for a uniform length, so mixed lengths fail. (Source: BWF Laws 2027, Law 2.2.2)
- The model is a natural feathered shuttle with a cork base covered by a thin layer of leather. (Source: BWF Laws 2027, Law 2.1)
- The feathers are fixed in the base, fastened with thread, and their tips form the open circle at the top. (Source: BWF Laws 2027, Law 2.2)
- 4.74, then 16, then 28, then 70. (Source: BWF Laws 2027, Law 2.2)
- The tips of the feathers lie on a circle 58 to 68 mm across. (Source: BWF Laws 2027, Law 2.2.3)

## 2.22 Synthetic and Adapted Shuttles

Materials, the synthetic skirt and its allowance, and modifications for local conditions.

### Test 1: Synthetic shuttles and shuttles adapted to local conditions

- A shuttle may be made of natural and/or synthetic materials. (Source: BWF Laws 2027, Law 2.1)
- A skirt, or a synthetic imitation of feathers, replaces natural feathers. (Source: BWF Laws 2027, Law 2.3.1)
- Because synthetic materials differ from feathers, up to 10 per cent variation is acceptable. (Source: BWF Laws 2027, Law 2.3.3)
- Synthetic materials differ from feathers in specific gravity and other properties. (Source: BWF Laws 2027, Law 2.3.3)
- Synthetic or natural, a shuttle has to fly the way the classic feathered one does. (Source: BWF Laws 2027, Law 2.1)
- The base is as for a feathered shuttle; the 10 per cent allowance covers the length, tip circle and weight. (Source: BWF Laws 2027, Law 2.3.2, 2.3.3)
- A modification may be made only with no variation in the general design, speed and flight. (Source: BWF Laws 2027, Law 2.4)
- Law 2.4 allows a modification where altitude or climate demand it, with the approval of the Member Association concerned. (Source: BWF Laws 2027, Law 2.4)
- 10, then 25, then 58, then 70 (the feathered figures, which a synthetic shuttle follows within 10 per cent). (Source: BWF Laws 2027, Law 2.3)
- Where altitude or climate make the standard shuttle unsuitable, the Member Association concerned may approve a modified one. (Source: BWF Laws 2027, Law 2.4)
