What Is The Standard Weight And Size Of A Basketball?
NBA Basketball Weighs 1.4 pounds
Although basketballs come in a variety of sizes, the NBA basketball weight is typically the average. So, if we’re talking about the weight of professional NBA basketball, it’ll be approximately 1.4 pounds.
The diameter of the ring is 29.5 inches. The air pressure is another critical thing to consider, which requires a normal air pressure of 7.5 to 8.5 pounds per square inch.

The Metric System Employs The Gram As The Measurement Of Weight.
Every player desires to play in the NBA, the most competitive and successful basketball league globally. Although there are various other organizations with varied styles, the NBA is the most well-known.

The proper weight for men’s basketball is 1.37 pounds, according to NBA regulations and specifications. The circumference, on the other hand, is 29.5 inches tall. As a result, you have a reasonable estimate of the weight of an NBA basketball.
Due to the physicality of females, the WNBA reduces the standard for weight and circumference. The WNBA basketball has a maximum weight of 1.13 pounds and a circumference of 28.5 inches.
How Much Does A Basketball Weigh In Grams?
Youth Basketballs Are Size 5
Do not worry if you do not know what pounds mean. The metric system employs the gram as the measurement of weight. Therefore, for your convenience, all the data is presented in gram form.
A basketball of size 4 weighs roughly 397 grams for junior balls. When compared to other sizes, it is relatively light, as previously stated.
The weight of the size 5 climbs dramatically, reaching 481 grams. Since this size is for youngsters aged ten and up, it is not difficult to comprehend. As a result, the weight and size of the players expand to fit their physique.
For their tournaments, several leagues and groups now collaborate with various manufacturing enterprises. Because it is the most competitive platform, the NBA is the gold standard for every basketball player. They utilize a 7-sized ball that is 623 grams in weight.
The WNBA uses a slightly different metric. They utilize a 6-sized ball that weighs 510 grams and has a 2-3 inches narrower circumference. If there is more air inflation pressure in the ball, these readings will alter as well.
The NCAA uses Wilson balls instead of Spalding balls. As a result, their men’s basketball weighs the same as the NBA but has a 30-inch diameter.
The weight of women’s basketball is roughly 566 grams, with a diameter of 29 inches. Basketball sizes are also measured differently by the International Basketball Federation.
Although they all weigh 566 grams, the production process causes them to feel somewhat different in hand. Men’s basketball has a circumference of 30.5 inches, whereas women’s basketball is 29 inches.
How Much Does A Youth Basketball Weigh?
Mini Basketball
The pro league for up-and-coming stars is the youth leagues, also known as junior basketball leagues. They do not play regular basketball and use a more miniature college basketball instead.
They also utilize mini basketballs, which are lighter than professional NBA basketballs. For conventional measures, youth basketballs are often designated as size 5.
It is lighter than NBA basketballs, weighing roughly 1.25 pounds. The circumference of the ring is approximately 27.5 inches. This sort of ball is used by any young player under ten for their regular training and games.
A 4-sized basketball may be used by anyone aged eight or younger. This ball is 25.5 inches in circumference, which is much less than that of conventional NBA balls. A size 4 is typically roughly 0.87 pounds.
How Much Does A Mini Basketball Weigh?
An Inflated Basketball Weigh At Least 22 Pounds.
Basketball sizes vary according to the gender, age, and skill level of the participants. For junior players in a school-level game, the ball may be of GL. The mini basketball typically weighs around 0.625 pounds (10 lb) or 283 grams (g) and is designed for children aged 3 to 5.
How Much Does A Women’s Basketball Weigh?
Women and men have various physical characteristics and features. As a result, the rules for basketball measuring varied. Women have their league, that’s the WNBA, where they may show off their prowess.
Basketball league sizes are mostly divided into two categories. The first is more extensive, measuring 29 inches in diameter and weighing 1.25 pounds. This basketball is a regular 6-inch basketball.
The other one is slightly smaller than 28 inches in diameter and weighs 1.125 pounds. According to the match requirements, condition, air pressure, inflation, and other criteria, the official match balls are chosen.
The standards for international forms follow the International Basketball Federation standards. While the Molten basketballs use some of the same materials as the Spalding basketballs, they are somewhat smaller and heavier.
These basketballs are high-quality leather. So, you should be able to spin a ball around your finger.
How Does A Properly Inflated Ball Weigh?
A Perfect Basketball Does Not Come With Sufficient Inflation.
In most cases, a perfect basketball does not come with sufficient inflation. If you’re playing on outdoor basketball courts, it is unlikely that you’ll notice.
The same cannot say the same for professional players who play regularly. You’ll wind up over inflating or under inflating your basketball if you don’t have a good understanding of properly inflated basketball weight.
The weight of an average inflated basketball must be at least 22 pounds. The inflation error margin, on the other hand, is roughly 0.03 pounds. So, if you stay in this range, that’s great.
How Is The Air Measured In A Ball?
Every Basketball Has Air Inside Of It.
The correct air pressure inside a basketball may make a massive difference in your game feel. However, to maintain appropriate pressure, you must understand how to gauge air pressure.
Here, you’ll learn how to maintain a high air density within the basketball by psi, or pounds per square inch, which is the standard pressure unit for basketball. Inside a basketball, the pressure should be between 7.5 and 8.5 pounds per square inch.
A pressure gauge is ideal for measuring air pressure, a standard instrument for determining the strength of a gas or fluid.
It is capable of calculating the overall pressure trapped inside a confined space. Gently put the gauge into the ball’s needle aperture while determining the air pressure. The psi within the ball will show on the dial or screen.
Final Thoughts
You can measure basketball in several different ways in circumference, inflation pressure, and total weight. When selecting a basketball, keep in mind your gender, age, and league you will use it.
Basketballs are sized and weighted differently in different leagues. As a result, understanding the proper size is critical to prevent getting disqualified from a game.
Hopefully, now that you are familiar with basketball sizes and have discussed how much does a basketball weigh in pounds, grams, or ounces and how it influences player performance. So, you will have a better understanding of the game.
How Much Does a Basketball Weigh?
When Dr. James Naismith invented basketball in 1891, he used peach baskets as goals and soccer balls (weighing only 16 ounces) for the first two years. Since then, the weight of a basketball has changed when the first basketball made of laced leather was manufactured in 1894. Decades later, genuine leather was used and then composite leather in the 1990s up until now. Because we now have standard basketballs in production, how much does a basketball weigh?
Before we answer that question, let us examine why the weight of a basketball is critical.
How Important is the Weight of a Basketball
There are standards for basketball size and weight for a reason. Can you imagine all these big guys at the NBA still shooting basketballs the size and weight of soccer balls? A properly inflated ball and one of the correct size are essential for proper skill development and basketball players’ safety.
Does a ball that is not adequately inflated affect the training of a basketball player? Of course! A ball with too little air will be too flat and impossible to dribble. An overly inflated basketball may also be challenging to dribble as it tends to stay high and difficult to control when shooting. Moreover, improperly catching an overly inflated ball or reaching for it as a defender may cause jamming of the fingers.
Thus, for the safety of the players and for their skill development, there is no other way but to use a properly inflated ball of the correct size and weight.
What’s the Standard Weight of a Basketball to Have?
If we are talking about a standard NBA basketball, the standard weight is 22 ounces or around 1. 4 pounds. (The weight of basketball in kg is 0.623 kg.) It measures 29.5 inches in circumference and is inflated to about an air pressure of 7.5 to 8.5 psi (pounds per square inch).
However, depending on the level of basketball you are playing, the official sizes and weight of the ball may vary. Let’s take a look.
How Much Does a Basketball Weigh in Various Basketball Leagues?
NBA Basketball Weight
As mentioned, the NBA basketball weight is 22 ounces or 1.4 pounds, give or take. (That is 623.69 grams if we are using the metric system.) The official NBA basketball has a circumference of 29.5 inches and an air pressure of 7.5 to 8.5 psi. The official NBA basketball is commonly referred to as a size 7.
WNBA Basketball Weight
The WNBA and the NBA may have a similar 10-foot hoop and 50 feet x 94 feet of court, but there is a slight difference between the weight of the basketball they use. While the NBA uses a basketball with a 29. 5-inch circumference, the WNBA uses a size 6 basketball, which measures 27.75 inches and weighs 18 ounces. If inflated to around 8 psi, the ball may reach a maximum of 28.5 inches in circumference and up to 20 ounces in weight.
NCAA Basketball Weight
Official NCAA basketballs are manufactured by Wilson, and it is a little bigger than the Spalding basketball the NBA uses. (The NBA has dropped its partnership with Spalding after this season and will use Wilson basketballs starting in 2021-22.)
The maximum circumference of a standard NCAA basketball is 30 inches and a weight of 22 ounces. The seams are no wider than 0.25 inches. On the other hand, a women’s NCAA basketball has a similar seam width but is only at around 20 ounces in weight and 29 inches in circumference.
FIBA Basketball Weight
The official balls used in FIBA basketball competition are manufactured by a company called Molten. Typically, the men use the GL7 series, and the women use the GL6. It is a little less heavy than Spalding and Wilson basketballs, weighing only 567 grams or 20 ounces. While it weighs less than an NBA basketball, it is also slightly more prominent at a circumference of 30.7 inches for men. Women’s basketball is around 29 inches in circumference.
How Much Does a Youth Basketball Typically Weigh?
Most of the junior or youth basketball leagues use a college ball. Otherwise, if a youth basketball is used, they weigh significantly less than NBA or college balls.
Typically, a youth basketball is referred to as a size 5 basketball. It is about 27.5 inches in circumference (70 cm) and weighs around 20 ounces (1.25 pounds). Most kids up to 10 years old use this type of basketball.
If need be, children eight years old and below use a smaller basketball. It is often referred to as a size 4 and weighs only 14 ounces with a circumference of 25.5 inches. After the size 4, the size 3 is what is referred to as a mini-basketball. It only weighs 10 ounces with a circumference of 22 inches.

7 Random Facts about Basketballs:
1. Spalding was the first manufacturer of basketballs in 1894 based on the design of the existing baseball. It has been the official manufacturer of NBA basketball since 1983 and until the 2019-20 season.
2. The Japanese manufacturer has been the official manufacturer of the balls used in international basketball competitions (including the Olympics and World Championships) sanctioned by FIBA. It has been doing so since 1982 until now.
3. The official Spalding NBA basketball is made of the finest full grain leather and costs a shade under $170.
4. Spalding became the official ball manufacturer of the Euroleague in 2012.
5. Albert Goodwill Spalding, the Spalding founder, was a pitcher for the Boston Red Stockings with an overall winning percentage of .796. He is also the first pitcher to get 200 wins.
6. Molten basketballs were made the Tokyo 1964 Olympics’ official basketball, only six years after the company’s inception.
7. Wilson has been the official partner of NCAA basketball since the 1990s and will take over as the NBA’s official basketball in the 2021-22 season. It was also the first partner of the league from 1946 until it was replaced by Spalding in 1983.
Wrapping Things Up: How Much Does a Basketball Weigh
For non-basketball fans, talking about the weight of a basketball seems irrelevant. However, for the sake of skill development and consistency, standard measurements of a basketball have been developed through the years.
In the game’s inception, Dr. Naismith has to make do with what’s already there– in this case, peach baskets and soccer balls. Soccer balls typically weigh around 16 inches and compared to the basketball sizes today, that’s about the weight of a size 5 basketball, one recommended for 9-11-year-old kids. It must have been pretty uncomfortable to shoot with!
As mentioned, there are already standard or official basketball sizes and basketball weights. A size 7 is the one used in the NBA and men’s NCAA. It is usually 22 ounces in weight, 29.5 inches in circumference, with air pressure between 7.5 to 8.5 psi. It is also the recommended ball for boys aged 15 and up. A size 6 basketball is the one used by the WNBA and NCAA. Tournaments for girls aged 12-14 years old use a size 6 basketball– 28.5 inches in circumference and 20 ounces in weight.
From there, youth basketball uses a different basketball weight and size. A size 5 basketball, 27.5 inches in circumference, and 17 ounces in weight are usually referred to as a youth basketball. A size 4 basketball is for kids 5-8 years old, and a size 3 basketball is often called the mini basketball. Even smaller than that, a size 1 basketball is called the micro-mini basketball; because, after all, it is only 16 inches in circumference and weighs only 8 ounces.
The Molten basketballs used in FIBA competitions, including the Olympics and World Championships, are also officially a size 7. That means they also weigh 22 ounces, but they may have a circumference of up to 30.7 inches rather than the typical 29.5.
Why is it important that we know all about the weight of basketball and its sizes? It is essential because it is not safe and is not conducive to basketball skills development. How so? An underinflated basketball is virtually impossible to dribble, while an overinflated basketball is hard to control and may injure fingers after a wrong catch. Because of these reasons, it is very critical to use basketballs and their recommended weight and sizes.
Those who are not familiar with basketball may get confused about the question, how much does a basketball weigh? After all, a ball is just a ball, right? Wrong! Official basketball weight and sizes exist for a reason, and as basketball players, it would be in our best interest to follow these propositions.

The word basketball consists of two English words - basket (basket) and ball (ball). The first part of the name arose because in the original version of the game, instead of a ring and a shield, a regular fruit basket with a cut-out bottom was used. What about the second part? What should be a basketball? What material is used to make it? Are there standards that establish the diameter and weight of the main basketball projectile? Look for answers to these and other questions in our article.
The main characteristics of the ball for basketball
The material used for the manufacture of modern basketball spheres is artificial leather. Every year, equipment manufacturers modernize the coating and improve the quality of the workmanship, making the ball more and more comfortable for athletes.
The optimum pressure for an inflated game ball is 7 to 9 psi, pounds-force per square inch.
It is customary to play basketball with an orange ball with black lines drawn on it, which divide the sphere into 8 equal parts. But this is not a dogma - in tournaments of different levels there are official balls of other colors. Much more important is the weight and diameter of the projectile.

Weight, size and circumference of a basketball
The so-called "seven" is used in men's team competitions. The weight of a size 7 basketball is from 567 to 650 grams. The diameter of the circle is 749-780 millimeters.
The diameter of the basketball used in women's competitions is smaller - from 724 to 737 mm. Weight - 510-567 g.
Children and young men play the so-called "five". This ball is even smaller and lighter. 690-710 millimeters is the allowable circumference. The mass of the ball of the 5th size is 470-500 g.
Different sizes of balls result from different hand physiology. Obviously, the smaller the grip, the smaller the ball.

FIBA Basketball
Basketball size standards are the same in European and American basketball. The differences are only in the manufacturing companies. The official ball of tournaments under the auspices of FIBA, the main European basketball federation, is the model of the Japanese company Molten, one of the largest market players in the world.
Competitions under the auspices of the Russian Basketball Federation are also held by the Molten model.
NBA Basketball
Spalding has been the official ball in North American Major League Basketball for many years. Moreover, the artificial leather model, introduced into use at some point, was not recognized by the players' council. As a result, the NBA returned to the traditional natural turf model.
The NCAA college basketball league in the United States uses a Chicago-brand Wilson ball. The same model is used in Russian university sports tournaments.

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. A rubber basketball would be a good choice for beginners as it is much easier to control and develop skills.
Best Selling Brands of Basketballs
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.
Spalding (USA)
Wilson (USA)
Molten (Japan)
Spalding makes balls for the world's most popular league, 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.
They utilize a 7-sized ball that is 623 grams in weight. 
They do not play regular basketball and use a more miniature college basketball instead. 
The mini basketball typically weighs around 0.625 pounds (10 lb) or 283 grams (g) and is designed for children aged 3 to 5.
However, to maintain appropriate pressure, you must understand how to gauge air pressure. 
As a result, understanding the proper size is critical to prevent getting disqualified from a game. 
Can you imagine all these big guys at the NBA still shooting basketballs the size and weight of soccer balls? A properly inflated ball and one of the correct size are essential for proper skill development and basketball players’ safety.
4 pounds. (The weight of basketball in kg is 0.623 kg.) It measures 29.5 inches in circumference and is inflated to about an air pressure of 7.5 to 8.5 psi (pounds per square inch). 
5-inch circumference, the WNBA uses a size 6 basketball, which measures 27.75 inches and weighs 18 ounces. If inflated to around 8 psi, the ball may reach a maximum of 28.5 inches in circumference and up to 20 ounces in weight.
It is a little less heavy than Spalding and Wilson basketballs, weighing only 567 grams or 20 ounces. While it weighs less than an NBA basketball, it is also slightly more prominent at a circumference of 30.7 inches for men. Women’s basketball is around 29 inches in circumference.
Tournaments for girls aged 12-14 years old use a size 6 basketball– 28.5 inches in circumference and 20 ounces in weight.
How so? An underinflated basketball is virtually impossible to dribble, while an overinflated basketball is hard to control and may injure fingers after a wrong catch. Because of these reasons, it is very critical to use basketballs and their recommended weight and sizes.
What about the second part? What should be a basketball? What material is used to make it? Are there standards that establish the diameter and weight of the main basketball projectile? Look for answers to these and other questions in our article.
