According to the official rules set by the National Basketball Association (NBA), a basketball weigh between 20.0 and 22.0 ounces (567 to 624 grams). This basketball weight range is also applicable to men’s college and high school basketball, as well as international competitions.
The weight of a basketball is specifically designed to allow players to grip the ball and perform various maneuvers such as dribbling, passing, and shooting with ease. If the ball were too heavy, it would be difficult for players to handle and control. On the other hand, if the ball were too light, it would be easier to handle but would not have the same level of bounce and control as a heavier ball.
Weight and Dimensions of NBA Basketballs Prior to 1979
Before 1979, the weight and dimensions of an NBA basketball were different from the current standards.
According to the official rules set by the NBA, the weight of an NBA basketball before 1979 was between 22.0 and 22.5 ounces (623 to 635 grams). This weight range was slightly heavier than the current weight range, which is 20.0 to 22.0 ounces (567 to 624 grams).
The circumference of an NBA basketball before 1979 was between 29.5 and 30.0 inches (750 and 762 mm). This measurement was slightly larger than the current circumference range for NBA basketballs, which is 29.5 to 30.0 inches (750 and 762 mm).
The circumference of a basketball refers to the distance around the ball and is an important factor in determining its size and grip. A larger circumference can make a basketball easier to handle and control, but it may also affect the ball’s bounce and performance.
FIBA Basketball Dimensions and Specifications
The dimensions of a basketball used in international competitions are regulated by the International Basketball Federation (FIBA) to ensure fair and consistent play.
According to the official rules set by FIBA, the circumference of a basketball must be between 74 and 78 centimeters (29.1 and 30.7 inches). This measurement is used to determine the size of the ball and is an important factor in its grip and handling.
The basketball weigh used in the international competition must be between 567 and 650 grams (20.0 and 22.9 ounces). The weight of a basketball affects its performance on the court, including its grip, bounce, and reaction time. Ensuring that all basketballs used in international competition fall within the specified weight range help to level the playing field for all teams and players.
How Much Does A Youth Basketball Weigh?
Youth basketball leagues use balls within this weight range, depending on the age and skill level of the players.
Youth basketball leagues often utilize mini basketballs, which are lighter and smaller than the balls used in professional NBA games. These mini basketballs, also known as size 5 balls, are specifically designed for young players under the age of ten and are typically used for their training and games.
Size 5 basketballs weigh approximately 1.25 pounds and have a circumference of 27.5 inches, making them lighter and smaller than NBA basketballs. This size and weight make them easier for young players to handle and control.
For even younger players, a size 4 basketball be used. These balls are 25.5 inches in circumference and weigh approximately 0.87 pounds. They are designed for players aged eight or younger and provide an additional level of difficulty and challenge as players progress in their skills.
|5||27.5 inches||1.25 pounds||Under 10 years old|
|4||25.5 inches||0.87 pounds||8 years old or younger|
How much does BASKETBALL weigh in a WNBA?
Women’s National Basketball Association (WNBA) basketball weigh is the same as that of a basketball used in men’s professional games.
|Dimension||WNBA Basketball||NBA Basketball|
|Circumference||28.5 inches||29.5-30.0 inches|
|Weight||20 ounces (1.3 pounds)||20.0-22.0 ounces (567-624 grams)|
|Inflation (psi)||7.5-8.0 psi||7.5-8.0 psi|
How Much Does a Basketball Weigh in the NCAA?
The basketball weigh in the National Collegiate Athletic Association (NCAA) is the same as that used in the National Basketball Association (NBA) and other professional and international competitions.
The inflation level of a basketball refers to the amount of air pressure inside the ball. The proper inflation level of a basketball is important for optimal performance on the court.
|Dimension||NCAA Men’s Basketball||NCAA Women’s Basketball|
|Circumference||29.5 inches (75 cm)||29 inches (74 cm)|
|Weight||22 ounces (1.4 pounds)||20 ounces (1.25 pounds)|
|Weight (grams)||624 gram||567 grams|
How much air pressure should a basketball have? (Inflation level of basketball)
According to the official rules set by the National Basketball Association (NBA), a basketball must be inflated to a pressure of 7.5-8.0 pounds per square inch (psi). This inflation level is applicable to all official NBA games, as well as men’s college and high school basketball, and international competitions.
A ball that is overinflated will be too hard and bouncy, making it more difficult to handle and control. On the other hand, a ball that is underinflated will be too soft and lack the necessary bounce, making it more difficult to shoot and pass. It is important to maintain the proper inflation level of a basketball to ensure optimal performance on the court.
The inflation level of a basketball can be checked using a pressure gauge or by using the “thumb test.” To perform the thumb test, hold the ball in one hand and use your thumb to press down on the ball. The ball should feel firm but not too hard. If your thumb sinks too easily into the ball, it may be underinflated. If the ball feels too hard and does not compress under your thumb, it may be overinflated.
It is important to note that the inflation level of a basketball may vary slightly based on the specific brand and model of the ball. Some basketballs may have different recommended inflation levels, so it is always a good idea to check the manufacturer’s recommendations before inflating the ball.
