How to measure basketball size

Basketball Sizes: A Quick Guide for All Levels of Play

NBA and College Basketball Sizes

Basketball sizes vary by age, gender, and level of play. The official size of the basketball used by the NBA is 29.5 inches in circumference. That’s the same size used throughout men’s college and high school basketball leagues. The WNBA uses a slightly smaller ball, measuring 28.5 inches in circumference.

For international play, specifically FIBA, the basketball used is what’s 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.

Youth Basketball Sizes

Boys in middle school (or ages 12-14), use a 28.5-inch ball, as do all women and girls ages 12 and up. For anyone, male or female, between the ages of nine and 11, a ball size of 27. 5 inches in circumference is recommended and is the most commonly sized ball used in youth basketball leagues.

Boys and girls between the ages of 4 and 8 use a basketball between sizes of 22 inches and 24.5 inches in circumference, depending on the individual’s hand size, which can be determined by a coach or parent by measuring from the bottom of the individual’s palm to the tip of his or her middle finger.

An NBA basketball must be inflated to a pressure of 7.5 to 8.5 PSI. The WNBA uses the same pressure regulations.

In the NCAA, inflation requirements are given in weight, with the men’s ball having a maximum weight of 22 ounces and the women’s ball having a maximum weight of 20 ounces. In FIBA play, the official rules state that the ball “be inflated to an air pressure such that, when it is dropped onto the playing floor from a height of approximately 1,800 mm measured from the bottom of the ball, it will rebound to a height of between 1,200 mm and 1,400 mm, measured to the top of the ball. ”

A standard NBA basketball has a diameter between 9.43 and 9.51 inches. In the WNBA, the basketball has a diameter of between 9.07 and 9.23 inches. Basketballs used in the NCAA are between 9.39 and 9.55 inches for men and 9.07 and 9.23 inches for women.

Basketballs used for indoor and outdoor play differ in their material. Indoor basketballs are made of full-grain leather; basketballs meant for outdoor use are made of rubber.

Though basketballs made for indoor use may initially feel smooth to the touch, after a few uses, they become somewhat broken in and easier to grip, much like a baseball mitt. Leather basketballs should not be used outside because the concrete surface of an outdoor basketball court causes the leather to roughen and wear, which eventually ruins the ball’s grip.

Some indoor basketballs are made of composite or synthetic leather. The upside is that they don’t need to be broken in like a regular leather ball. But generally speaking, the quality is not as good.

Outdoor, or “street” balls, employ a rubber surface because it can absorb the rougher surface of a concrete court without sacrificing the ball’s grip. A rubber ball is also a good choice for beginners because it is the easiest ball to control.

The three best-selling basketball brands are Spalding, Nike, and Wilson. As the official ball of the NBA, Spalding is perhaps the most recognized basketball manufacturer. Nike and Wilson are also popular thanks to the variety of textures, technologies, and color schemes they offer.

A typical official-size men’s basketball retails on average between $30 and $60. Both the NBA and WNBA use Spalding basketballs, while the NCAA and most youth leagues use Wilson. As mentioned previously, FIBA and international leagues use Molten as their basketball provider.

Basketball

Basketball sizes come in variations for different ages, genders, and level of play. The official NBA and competitive professional basketball is 29.5” | 74.9 cm in circumference with a diameter between 9.43”-9.51” | 24-24.2 cm. Professional basketballs must be inflated to a pressure between 7.5-8.5 PSI and cannot exceed the maximum weight of 22 ounces. When choosing a basketball, consider whether the play environment will be primarily outdoor or indoor because indoor basketballs perform best as full-grain leather constructions and outdoor basketballs are better as rubber.

Basketball size varies by league, governing body, and gender and age of students. Basketballs differ from each other in weight, pressure, circumference and material of manufacture. According to the official rules of the game, the game projectile must have a spherical shape, be made in orange and have 8 black inserts and seams.

The official size of a basketball is numbered 7, it has the following characteristics: weight (mass) is - 567-650 grams, circumference - 749-780 cm, atmospheric pressure - 0.56 - 0.63 kg / cm ² . This is the largest ball, and now look at the rest in the table:

Size	Circumference (cm)	Weight (grams)	Pressure (kg/cm 2)	Where applicable
7	749-780	567-650	0.56 - 0.63	Professional Men's Basketball, Boys 14+
6	724-737	510-567	0. 56 - 0.63	Women's professional basketball, girls 12+, boys 12-13
5	690-710	470-500	0.56 - 0.63	Boys and girls 10-11 years old
3	560-580	300-330	0.56 - 0.63	Boys and girls 4-9 years

Pass the Basketball Test

Basketballs are made from natural leather or synthetic leather - the pressure is the same for all sizes. It is worth remembering that a correctly inflated ball of the correct size is important to ensure quality training and skill development for players of different ages.

For games held under the auspices of the International Basketball Federation (FIBA), the ball is inflated to air pressure so that when it falls onto the court from a height of 1.8 meters, it should bounce to a height of 1.2-1.4 meters (measured by the top of the game ball).

Indoor and outdoor basketballs

There are no differences between the versions of the game in terms of size, but there are other nuances regarding manufacturing. Indoor balls are made of genuine leather, and outdoor balls are made of rubber.

Leather basketballs intended for indoor use should not be used outdoors. Concrete or asphalt surfaces cause the leather to become rough and wear out quickly, eventually resulting in poor hand-ball contact. Also, some balls for playing inside are made of composite or synthetic leather, but their quality leaves much to be desired.

For outdoor play, manufacturers make balls with a rubber surface, as it is able to interact better with rough field surfaces. Rubber basketball will be a good choice for beginner players as it is much easier to control and develop skills.

Best Selling Basketball Brands

Basketball is very popular all over the world, which means that ball manufacturers do not have to sit idle, because they need to compete, create a quality product and, accordingly, make a profit. Here are the 3 best selling basketball brands in the world.

1. Spalding (USA)
2. Wilson (USA)
3. Molten (Japan)

Spalding makes balls for the most popular league in the world, the NBA. Wilson is in demand with the NCAA and most of the youth leagues in the United States of America. But Molten is the main supplier of game equipment for FIBA ​​tournaments, European championships and even the Olympic Games.

Note that on average for men, a standard size 7 basketball sells for $30-60.

Basketballs have changed a lot since the beginning of the game in the late 19th century. Today, technology has made it possible to make very high-quality and even smart balls. This was not always the case, because decades have passed and the balls have undergone many changes and improvements, although at the very beginning, James Naismith, the founder and father of basketball, used a soccer ball to play, which his students threw into peach baskets.

A new wave of basketball ball design, sweat throughout the appearance, will stand out flawless technology. This applies to the panels of the game projectile - now there are 8 of them, and the new composite structures have only two. New modern balls are constantly advertised by manufacturers. There are those that can control humidity, have more pimples - dots, and are even able to track the entire process of the game and in live mode and send information (strength of throw, rotation, impact) to Android or iPhone. Such a ball is 94FiFty.
