Badminton is the fastest racquet sport in the world. The shuttlecock, also known as the birdie, can travel at speeds exceeding 300 km/h (186 mph) and has been recorded at a maximum speed of 493 km/h (306 mph) by Tan Boon Heong of Malaysia. The speed of a birdie is influenced by various factors, including altitude, temperature, humidity, racket design, and body positioning. The design of the birdie itself, including the arrangement of its feathers, also plays a crucial role in its speed. The optimal racquet angle for achieving maximum speed is 71.6 degrees, which is challenging to execute consistently unless one is a highly skilled player.

What You'll Learn
Badminton is the world's fastest sport
The speed of the shuttlecock in badminton can exceed 300 kilometres per hour (km/h) or 200 miles per hour (mph). The fastest recorded birdie hit in a competitive badminton game was 426 km/h (264 mph) by Danish player Mads Pieler Kolding. In testing, Malaysian player Tan Boon Heong hit a smash measured at 493 km/h (306 mph). To put this into perspective, the fastest golf drive recorded is 349.38 km/h (217.09 mph), and the fastest serve in tennis is 263 km/h (163 mph).
The speed of the shuttlecock is influenced by various factors, including the design of the birdie and the racket, the racket string tension, body positioning, and atmospheric conditions. For example, the birdie will travel faster at higher altitudes due to lower air density, and it will also travel faster in warmer weather for the same reason.
The technique of the player also affects the speed of the birdie. National badminton umpire and coach, Dr Zhu, found that a racquet angle of 71.6 degrees optimises the transfer of speed from the player's body to the shuttlecock. This angle is difficult to achieve consistently unless the player is very experienced.

The fastest birdie speed ever recorded
The fastest badminton smash speed ever recorded is an astonishing 565 km/h or 351.04 mph, achieved by Indian badminton player Satwiksairaj Rankireddy in April 2023. This smash broke a decade-old record of 493 km/h or 306 mph, previously held by Malaysian badminton player Tan Boon Heong. To put this into perspective, the fastest speed recorded by a Formula 1 car is 397.48 km/h or 247 mph, while the fastest tennis serve maxes out at 263 km/h or 163 mph.
The speed of a badminton birdie or shuttlecock is influenced by various factors, including the design of the birdie and racket, racket string tension, body positioning, and atmospheric conditions. The birdie's lightweight construction, with a cork base and carefully selected goose or duck feathers, contributes to its aerodynamics and speed. The feathers create drag, resulting in a predictable flight path and increased control for the player.
The smash is the most powerful shot in badminton, and the speed of the birdie can be further enhanced by the player's technique. The optimal racquet angle to transfer the most speed to the shuttlecock is 71.6 degrees, which is challenging to achieve consistently without a high level of expertise. Additionally, the strings' elasticity and tension play a role in the birdie's speed, with low-tension strings producing faster shots.
The speed of the badminton birdie is not only impressive but also showcases the skill and technique of the players, making badminton an exciting and dynamic sport to watch and play.

How to choose shuttlecocks based on speed
The speed of a shuttlecock is an important factor to consider when choosing one for your badminton game. The speed of the shuttlecock determines how far it will travel when struck with standard force. The speed is dependent on the air density in the area. If the total amount of air is less in an area, it means it has lower air density, and the shuttlecock will travel faster. So, if you live in a mountainous region with low air density, choose a slow-speed shuttlecock as it will be sufficient.
Shuttlecocks are typically made with a cork or rubber base and feathers or plastic for the upper section. The feathers are arranged in a cone shape, which helps to reduce air resistance and increase speed. The higher the feather count, the better the durability and stability of the shuttlecock. The weight of the shuttlecock also affects its speed. Traditionally, manufacturers used the weight of the shuttlecock to categorise them. Most shuttlecock tubes are marked with numbers ranging from 48 to 52, indicating their weight in grams.
When choosing a shuttlecock, consider the temperature and humidity of your playing environment as these factors can affect the shuttlecock's flight characteristics. Shuttlecocks perform differently in varying temperatures. In hot weather, the shuttlecock travels faster, while in colder regions, the shuttlecock speed is slower. The humidity of the area also affects the shuttlecock speed. A more humid environment can slow down the shuttlecock.
Different brands offer a range of shuttlecocks with varying speeds. Yonex, for example, offers the Aerosena AS30 Speed 78, which is the most popular in the UK and is used by higher-level clubs and tournaments. The Victor Gold Champion is another popular choice, known for its consistency and durability. If you're a beginner, a plastic shuttlecock is recommended as it is more affordable and durable. These shuttlecocks have slower speeds, making them easier to control.
When buying shuttlecocks, consider the speed numbers on the tube, the weight, the feather count, and the brand. Choose a speed that suits your playing environment, taking into account the altitude, temperature, and humidity. By selecting the right shuttlecock speed, you can improve your game significantly.

Basic badminton smash techniques
The badminton smash is one of the most powerful and thrilling shots in the sport. It can reach incredible speeds—during testing, one badminton player recorded a smash of 493 km/h (306 mph)!
Stance
Stand with your feet shoulder-width apart, distributing your weight evenly on both feet, ready to shift forward as you execute the smash. This sets the foundation for a successful smash.
Grip
The grip is critical to the power and control of your smash. The most common grip for smashing is the forehand grip. To hold the racket, imagine shaking hands with it. Your thumb and index finger should form a V-shape on the handle, and your hand should be at the bottom of the grip handle. This creates a longer lever, helping you generate more power. Ensure your grip is firm yet relaxed, allowing for better wrist action, which is essential for generating power.
Swing
The swing is where most of the power and speed of a smash come from. As you prepare to smash, bring your racket back behind your body. Your elbow should be high, and your non-racket arm should point towards the shuttlecock, helping with balance and aim. To perfect your swing, practice hitting the shuttle at the highest point and work on your hand-eye coordination.
Follow-Through
Always complete your swing for a more powerful shot. After making contact with the shuttlecock, your wrist should snap forward to make the birdie travel downward. The energy from your body transfers to the racket head and ultimately to the birdie.
Practice Drills
Even with the right techniques, players often make mistakes. To master the badminton smash, consistent practice is key. One drill you can try is shadow smashing, where you practice the smashing motion without a shuttlecock to perfect your technique. You can also record yourself playing smashes and compare your technique to suggested methods, or practice with a partner who can feed you high serves to smash.

The design of the birdie and its effect on speed
The design of the shuttlecock, or birdie, has a significant effect on its speed and flight characteristics. The birdie is designed to be stable in flight, giving players more control over shots, especially at high speeds.
The shuttlecock is made from 16 carefully selected goose or duck feathers, although some sources state that only feathers from the left or right wing should be used in each shuttlecock. These feathers are embedded into a rounded cork base, made from the bark of a cork tree, with some shuttlecocks also featuring a thin leather or synthetic covering. The total weight of the shuttlecock is approximately 4.75-5.5 grams. This lightweight design, coupled with the feathers, creates a high-drag projectile that is very aerodynamic and can reach high speeds.
The feathers on the shuttlecock create drag, which results in a more predictable flight path and increased control for the player. The symmetrical cone shape of the feather skirt ensures stability in flight, allowing the shuttlecock to always turn cork first, no matter the initial orientation. This unique design, when compared to other sports projectiles, allows the shuttlecock to decelerate faster than a ball. The angle and force of a stroke can also influence the trajectory and speed of the shuttlecock.
The speed of a shuttlecock is also influenced by external factors, such as altitude and temperature. Higher altitudes and warmer temperatures result in lower air density, which allows the shuttlecock to travel faster. Conversely, increased humidity can slow down the shuttlecock as it absorbs moisture from the air. The choice of feathered or synthetic shuttlecocks can also impact speed, with feathered shuttlecocks capable of reaching higher speeds.
