29.5 inches long The size of a basketball in the National Basketball Association (NBA) is 29.5 inches (75 cm), with a maximum circumference of 29 inches in the Women's National Basketball Association (WNBA). NCAA, NBA, or WNBA sized balls are typically used in high school and junior leagues.
The ball is made of leather with a latex coating for durability. It is oval-shaped with panels of blue and red color-coordinated stitching. The ball has 8 large air holes that allow it to be inflated with air.
Basketballs are measured by their circumference; thus, the size of a ball varies depending on how much pressure it receives while being inflated. A ball that is too small will not give players enough control, whereas a ball that is too large can cause serious injuries, such as torn ligaments, when shot by athletes.
There are two types of basketballs: street and court. Court balls are larger than street balls and are designed for indoor use only. They are also known as regulation balls because they must meet specifications set by the National Federation of State High School Associations (NFSHSA). Street balls are smaller and have more bounce than court balls but can be used indoors and out. They are also branded as "college" or "high school" balls depending on the age group they are intended for.
A normal NBA basketball measures between 9.43 and 9.51 inches in diameter. The basketball in the WNBA has a diameter of 9.07 to 9.23 inches. Basketballs used in the NCAA range in size from 9.39 to 9.55 inches for men and 9.07 to 9.23 inches for women. So, overall, college and professional basketballs are about the same size.
According to WNBA (Women's National Basketball Association) guidelines, the ball must be at least 28.5 inches (72.4 cm) in circumference. The NBA ball is 1.00 inch (2.54 cm) smaller. Thus, compared to the men's game, the ball in women's basketball is generally sized smaller.
The difference in size between the men's and women's balls results from rules adopted by the Women's National Basketball Association (WNBA) to mitigate some of the differences between the games played by men and women. Men are generally taller and stronger than women, so they require a ball that is easier to handle. A smaller ball is also necessary because women need more space to move comfortably. There are also regulations regarding how far behind the backboard the ball may be thrown by a player attempting a throw-down field goal.
In addition, the WNBA requires that each team be allowed only six players on the court during play. This limits the number of people who can have a hand in deciding how the ball rolls after it is released. Since no one else is allowed in the circle when you shoot, you have to trust that the ball will go in.
This is not to say that men aren't capable of playing with the women's ball. Some men's leagues around the country use balls that are equal in size to those used by their female counterparts.
Basketball sizes change depending on age, gender, and level of play. The circumference of the official NBA and competitive professional basketball is 29.5" or 74.9 cm, with a diameter ranging from 9.43" to 9.51" or 24-24.2 cm. The ball is about 1/2" or 12 mm thick.
By age 10, most children are able to jump as high as they can reach. Young adults generally jump higher than this. College students who play varsity basketball can jump up to 6 feet (183 cm) in height. Professional players may be able to jump higher than this.
The maximum height that a player can jump is determined by how high he can lift his legs when standing on a chair or bench. If a player cannot reach this height, then he cannot go higher than that line on the court.
The average adult male can jump around 3 feet (91 cm), while the average female can jump around 2 feet (61 cm). Children can jump much higher than this; it's just that they usually lose momentum after they hit this height.
Junior high school boys can jump around 4 feet (121 cm), while junior high school girls can jump around 3 feet (91 cm). High school boys can jump around 5 feet (152 cm) and high school girls can jump around 4 feet (122 cm).
According to USA Basketball, NBA basketballs have a circumference of 29.5 inches, while WNBA basketballs have a maximum circumference of 29 inches. Both should be inflated to 7.5 to 8.5 pounds per square inch of pressure. That's the same as a medium-size ball.
Basketballs are made from leather, with synthetic strings and yarn filling making up the rest of the ball. They are porous, so they must be cleaned and treated with oil or cream to keep them soft and shiny.
They may look like toys, but basketballs are powerful objects that can cause injury if not handled properly. It is important to take care of your equipment because lost balls mean missed shots for your team. In addition, worn out balls are less likely to rebound off of the backboard correctly, which could lead to injury for you or someone on your team.
When talking about the weight of basketballs, it is important to understand how they are measured. The ball's mass is measured by putting it into a machine called an "indicator". The indicator measures the force of gravity on top of the ball, giving us its absolute weight.
Since air pressure affects the weight of objects, air pressure changes will affect the weight of a basketball. As I mentioned earlier, basketballs are usually inflated to between 7.5 and 8.5 psi.
Basketball height differs depending on age, gender, and level of play. The NBA's official basketball size is 29.5 inches in circumference. These basketballs are often two colors and somewhat larger, with a 30.7-inch circumference for the men's ball and a 29.7-inch circumference for the women's. Smaller basketballs are used in youth sports, while larger balls are used by professional teams.
In terms of total weight, men's basketballs range from 33 to 36 ounces, while women's basketballs range from 32 to 35 ounces.
As far as shape, both men's and women's basketballs are roughly spherical. Men's balls are generally more rounded with slightly less air space between the strings, which helps maintain their round shape under pressure from play. Women's balls are flatter with more air space between the strings, which makes them easier to handle for little girls who might want to play pickup games or travel basketball.
Overall, men's and women's basketballs are almost identical in size and shape. The only real difference is that the ball is usually about 1 inch higher for women than it is for men because the basket is raised to give women a better view of the game. Otherwise, the balls are the same dimensionally.
