Basketball is a team sport played by two teams, most commonly of five players each, on a rectangular court. The objective is to shoot a basketball through the defender's hoop, or basket, while preventing the opposing team from doing the same. The ball is spherical and usually has an orange surface with black ribs and a possible logo. It is made of leather, rubber, or a synthetic composite, and has an inflatable inner rubber bladder, which is wrapped in layers of fibre. The circumference of a basketball used in the NBA is 29.5 inches (75 cm), while the WNBA uses a ball with a maximum circumference of 28.5 inches (72 cm).

What You'll Learn
Basketballs are spherical
The spherical shape of basketballs is essential for the game's dynamics and the skills required to play. The ball must be durable, easy to grip, and predictable in its bounce. It is often made of leather, rubber, or synthetic composite materials, with an inflatable inner bladder, to ensure it can withstand the continuous dribbling, passing, and shooting during a game.
The spherical shape also contributes to the ball's performance and flight stability. Advancements in technology have led to the use of synthetic compounds and advanced polymers, which offer improved durability and responsiveness. These innovations enhance the overall gameplay experience, making it more efficient and responsive.
Maintaining proper inflation is crucial for basketballs to perform optimally. Overinflation can make the ball harder and less responsive, while underinflation reduces its bounce. The ideal pressure for a basketball is between 7.5 and 8.5 PSI, ensuring a balance between playability and safety.
Basketball players themselves also need to be in good "basketball shape," which encompasses various aspects of physical fitness. This includes cardiovascular fitness, strength, and mobility, all of which contribute to a player's ability to endure the physical demands of the game and execute skills effectively.

They are made of leather, rubber, or synthetic composite
Basketballs are made of leather, rubber, or synthetic composite. The outer cover of the basketball is usually made from diverse materials. High-quality basketballs are made from quality leather, while other basketballs are made from synthetic rubber or regular rubber. The leather pieces are sorted by how clear the grain is, as well as the thickness and size of the piece. The chosen leather pieces are then coloured and put into tanning drums where the leather is preserved and tanned. The leather is then stamped with a 1,000-ton press to give the basketballs their distinct pebbling.
If leather is used for the outer cover, it is stitched together around the ball. If any type of rubber is used, it is glued to the ball. Basketballs designated for indoor use are generally made of leather or absorbent composites, while balls for all-surface use are made of rubber or durable composites. Indoor balls tend to be more expensive than all-surface balls due to the cost of materials.
The inner bladder of the basketball is made of rubber. To create the inner bladder, black butyl rubber is melted into flat panels. The panels are then attached to form the shape of a basketball. A small hole is pierced in the bladder so that an air filler tube can be installed. The inner bladder is inflated and left for 24 hours. With the help of a machine, polyester or nylon threads are then wrapped around the inner bladder to create a spherical shape. The threads also prevent the ball from deforming.
The materials used to make basketballs have changed over time, but the main design has remained largely the same. Advancements in technology have led to the development of synthetic compounds and advanced polymers that offer improved durability and performance.

They are inflated to 7.5-8.5 PSI
A basketball is a spherical ball used in basketball games. It is usually made of leather, rubber, or a synthetic composite, and has an inflatable inner rubber bladder. Inflating a basketball to the correct pressure is essential, as it ensures the ball bounces predictably and consistently. The recommended PSI (pounds per square inch) varies depending on the league and type of basketball used.
The NBA and WNBA require a precise range of 7.5 to 8.5 PSI. This narrower range is designed to maintain consistency and fairness while accounting for variations in playing conditions and environmental factors. Maintaining the correct air pressure in a basketball is crucial for ensuring consistent gameplay across different levels of competition. A basketball inflated to the proper PSI ensures that it bounces predictably, allowing players to anticipate its movements and adjust their gameplay accordingly.
When a basketball is overinflated, it can significantly impact various aspects of gameplay. It may react in unusual ways upon impact with surfaces such as the backboard, rim, or floor. The ball's higher bounce and unpredictable movement can affect offensive and defensive strategies, making it challenging for players to anticipate where the ball will go after it hits a surface.
On the other hand, underinflation reduces the ball's bounce and makes it feel sluggish. An underinflated basketball absorbs more force upon impact, leading to a weak and inconsistent bounce. This makes dribbling more difficult, as the ball does not return to the player's hand with the same energy applied to it. Additionally, an underinflated basketball feels heavier, which can affect shooting accuracy and reduce the ball's ability to travel smoothly through the air.
Therefore, it is important to check the air pressure in a basketball before every game or practice session. This ensures that the ball is at the correct PSI and performs as expected. Checking the air pressure periodically throughout the season is also good practice, as changes in temperature and humidity can affect the ball's air pressure.

Their diameters range from 24-24.2 cm
Basketballs are spherical in shape. Their diameters vary depending on the league and the age, gender, and level of play. The standard diameter for a basketball in the National Basketball Association (NBA) is 9.43–9.51 inches (24–24.2 cm). This is also the diameter specified for high school and junior leagues, which normally use NBA-sized balls.
The diameter of a basketball can also depend on its circumference. For example, a youth basketball with a circumference of 27 inches (69 cm) will have a smaller diameter than an NCAA men's ball, which has a maximum circumference of 30 inches (76 cm).
The diameter of a basketball can also be influenced by the materials used in its construction. Basketballs are usually made from leather, rubber, or synthetic composites, and the choice of material can affect the ball's size. For instance, indoor balls made of leather tend to be more expensive and require "breaking in" to achieve optimal grip, while outdoor balls are generally made of more durable materials like rubber or composites.
The size of a basketball also depends on its intended use. Basketballs can range in size from very small promotional items to extra-large balls nearly 2 feet (60 cm) in diameter used in training exercises.

They weigh 22 ounces or less
A basketball is a spherical object, and this three-dimensional shape allows players to easily roll, bounce, and handle the ball in a variety of ways. Moving on to its weight, regulation basketballs used in competitive leagues like the NBA and WNBA typically weigh around 22 ounces or less. This weight range is carefully calibrated to balance several factors, ensuring the ball is neither too heavy nor too light.
The 22-ounce weight limit is an important specification that influences how the game is played. Heavier balls tend to be harder to control and can fatigue players more quickly, especially during intense gameplay. A lighter ball, on the other hand, is easier to control and can facilitate faster play, increasing the pace of the game. The 22-ounce weight (or lighter) strikes a balance between these factors, accommodating a wide range of playing styles and skill levels.
This weight also takes into account the fact that basketball is a game of skill and precision. A lighter ball allows players to more easily manipulate its trajectory, spin, and direction, enabling a greater degree of control and facilitating more complex plays. The weight contributes to the overall playability of the ball, ensuring that it is responsive to the player's actions without being cumbersome.
Additionally, the 22-ounce weight limit (or less) is a safety consideration. Basketball is a fast-paced sport with a lot of player contact and quick movements. A lighter ball reduces the risk of injury from ball impact, especially when players are driving to the basket or rebounding. This weight also reduces the risk of injury to younger or smaller players, ensuring that the ball is manageable for a wide range of participants.
Finally, the weight of a basketball can influence the development of skills and the overall accessibility of the sport. Lighter balls are often used for training purposes, helping players develop their technique and form without straining their arms and wrists. This weight specification, therefore, contributes to the learnability and inclusivity of the game, accommodating players of different ages, sizes, and skill levels.
