between 75 and 95 grams ( 2 . 6 to 3 . 3 ounces ) including the strings .

Strings
- Badminton strings are thin , high performing strings in the range of about
0 . 62 to 0 . 73 mm thickness .
- Thicker strings are more durable , but many players prefer the feel of
thinner strings .- String tension is normally in the range of 80 to 160 N ( 18 to 36 lbf ) .
- Recreational players generally string at lower tensions than
professionals , typically between 18 and 25 lbf ( 110 N ) .
- Professionals string between about 25 and 36 lbf ( 160 N ) .

Grip
- The choice of grip allows a player to increase the thickness of his racquet
handle and choose a comfortable surface to hold .
- A player may build up the handle with one or several grips before
applying the final layer .
- Players may choose between a variety of grip materials .
- The most common choices are PU synthetic grips or towelling grips .

Shuttlecocks with feathers
- A shuttlecock ( often abbreviated to shuttle ) is a high ± drag projectile ,with an open conical shape : the cone is formed from sixteen
overlapping feathers embedded into a rounded cork base .
- The cork is covered with thin leather or synthetic material .
- Synthetic shuttles are often used by recreational players to reduce their
costs as feathered shuttles break easily .- These nylon shuttles may be constructed with either natural cork or
synthetic foam base , and a plastic skirt .

Scoring system
- The basics
- Each game is played to 21 points , with players scoring a point whenever
they win a rally regardless of whether they served ( this differs from the
old system where players could only win a point on their serve and eachgame was played to 15 points ) .
- A match is the best of three games .

- Details
- When the serves , the shuttlecocks must pass over the short service
line on the opponents µ court or it will count as a fault .
- If the score reaches 20 ± all , then the game continues until one side
gains a two point lead ( such as 24 ± 22 ) , up to a maximum of 30
points ( 30 ± 29 is a winning score )

- Lets
- If a let is called , the rally is stopped and replayed with no change to the
score .
- Lets may occur because of some unexpected disturbance such as a
shuttlecock landing on court ( having been hit there by players on an
adjacent court ) or in small halls the shuttle may touch an overhead rail
which can be classed as a let .- If the receiver is not ready when the service is delivered , a let shall be
called ; yet , if the receiver attemps to return the shuttlecock , he shall
be judged to have been ready .
- There is no let if the shuttlecock hits the tape ( even on service ) .

doubles play .

- In a doubles play court , the badminton court size must be 20 by 44 feet.
- Of course , these are only for professional games ; you can use any
badminton court measurement outside of scheduled games .
