The equipment used in basketball is essential to the game, and the ball's specifications are important to the game's integrity and fairness. The weight of a basketball varies depending on the league and the age group of the players. For example, the official NBA basketball weighs approximately 22 ounces or about 1.4 pounds, with a circumference of 29.5 inches, while a youth basketball could be 27 inches in circumference.

The Women's National Basketball Association (WNBA) uses a slightly smaller ball, with a maximum circumference of 28.5 inches, and a weight range of 7.5-8.5 pounds per square inch.
In the National Collegiate Athletic Association (NCAA), the men's basketball has a maximum circumference of 30 inches and weighs approximately 22 ounces, while the women's basketball has a maximum circumference of 29 inches and a maximum weight of 20 ounces. High school and junior leagues typically use basketballs with the same circumference as the NBA and WNBA balls but may vary in weight depending on the brand and model.
At the international level, men's basketballs have a circumference of 30.7 inches (size 7) and women's basketballs have a maximum circumference of 29 inches. The exact weight of these balls can vary depending on the specific league or competition.
The weight of a basketball is important for ensuring a level playing field, as a ball that is too light may not bounce correctly, while a ball that is too heavy can be difficult to handle and shoot.

The official weight of an NBA basketball is 21 to 22 ounces or about 1.3 to 1.4 pounds, which is equivalent to 623 grams. This weight is carefully chosen to balance playability and durability, allowing athletes to showcase their skills while enduring an 82-game season.
The weight of an NBA basketball is a crucial specification that contributes to the integrity and fairness of the game. Using balls of consistent weight across competitions ensures a level playing field, where the outcome is determined by the players' skills rather than equipment variations.
The NBA basketball is typically made of leather, with a circumference of 29.5 inches. The leather construction provides optimal grip and durability, enhancing the ball's performance during competitions.
It is worth noting that different leagues and levels of play have varying weight specifications for basketballs. For example, the NCAA uses a ball weighing around 20-22 ounces, while the WNBA ball weighs approximately 18-20 ounces, catering to the specific needs of athletes in each league.
Additionally, international basketball, governed by the Fédération Internationale de Basketball (FIBA), employs a ball weighing around 20-23 ounces, with slight variations in weight allowed.

Basketballs for international play in the International Basketball Federation (FIBA) are called Molten GL7 for men and Molten GL6 for women. These basketballs typically feature two different colours and are slightly bigger than the basketballs used in the NBA. The circumference of the Molten GL7 is 30.7 inches (780 mm) and it weighs 22 oz / 620 g (567 – 650 g). The Molten GL6 has a circumference of 29 inches (737 mm) and a weight of 20 oz / 570 g (510 – 567 g).
The FIBA balls are bigger than the official NBA balls, which have a circumference of 29.5 inches (75 cm). The NBA balls are also heavier than the WNBA balls, which have a circumference of 28.5 inches (72 cm).
The size of basketballs varies depending on the age, gender, and level of play. For boys and girls aged 9 to 11, a ball size of 27.5 inches (70 cm) in circumference is recommended and is the most common size used in youth basketball leagues. This is also the standard youth basketball size, also known as size 5. Size 6 is the official size for women, including high school, college, and professional, and is also recommended for boys aged 12-14 and girls aged 12 and up. Size 7 is the official size for men's high school, college, and professional, as well as boys aged 15 and up.
Basketballs used in competitions are usually made of synthetic leather, while premium leather is used for balls in the Olympic Games, World Cup, and European Championship. The cheapest basketballs on the market are made of rubber and are recommended for kids and beginners.

WNBA basketball weight
Basketballs are designed to be light, elastic, and durable. The weight of a basketball depends on its size, which varies by age, gender, and level of play. The official size of the basketball used by the NBA is 29.5 inches in circumference, while the WNBA uses a slightly smaller ball, measuring 28.5 inches in circumference and weighing 20 ounces. This is the same size used by boys in middle school (or ages 12-14) and women and girls ages 12 and up.
For international play, specifically FIBA, the basketball used is called a Molten GL7 for men and Molten GL6 for women. These basketballs typically feature two different colors and are slightly bigger, with a 30.7-inch circumference for the men's ball and a 29-inch circumference for the women's.
The surface of the ball is nearly always divided by "ribs" that are recessed below the surface in a variety of configurations and are generally a contrasting color. The traditional color scheme of basketballs is orange with black ribs, but they are sold in various colors. WNBA basketballs, for instance, have an orange and white color scheme, which was chosen to differentiate them from the all-orange balls used in the NBA and to improve the appreciation of the players' shots.
The balls are generally designated for indoor or all-surface use. Indoor balls are usually made of leather or absorbent composites, while all-surface balls are made of rubber or durable composites. Indoor balls tend to be more expensive due to the cost of materials. Additionally, brand new all-leather indoor balls must be "broken in" before use in competition to achieve optimal grip. The pros in the WNBA and NBA use genuine cow leather for their balls.

Youth basketball weight
The weight of a basketball is directly proportional to its size. The standard weight of a size 7 basketball, used in men's professional basketball, is 22 ounces. The weight of youth basketballs varies with size, and it is imperative to choose the right size basketball for optimal performance, development, and enjoyment.
For instance, a size 6 basketball, used by females aged 9+ years and males aged 9 to 12 years, weighs 20 ounces. A size 5 basketball, used by boys and girls aged 8 to 9 years, has a standard weight of 14-16 ounces. Size 4 basketballs, meant for kids up to 7 years old, weigh around 14 ounces. Size 3 basketballs are novelty-sized or 'mini' basketballs suitable for all ages, weighing about 10 ounces.
It is important to note that the weight of a basketball can impact a player's technique and performance. A basketball that is too heavy for a young player can make the game less enjoyable. It becomes harder to catch, more challenging to control when dribbling, and more difficult to pass or shoot accurately. Therefore, it is crucial to select a basketball that is appropriate for the player's age and size.
Additionally, the weight of a basketball is influenced by its construction material. Leather basketballs, for instance, are not recommended for outdoor use as the concrete surface can damage the leather, affecting the ball's grip. On the other hand, rubber basketballs, also known as street basketballs, are designed for outdoor play and can withstand rough surfaces without compromising grip.
