How Many Dots Does A Basketball Have? Quick Look – Basketball Word!
Spalding was one of the first companies to produce the official game ball for basketball professionally. Still today they are the official basketball of the NBA. But one thing many people often wonder is what is the purpose of those dots and exactly how many are there on the ball.
How many dots does a basketball have? A Men’s basketball which is 29.5 inches in circumference has 122 dots per square inch on the basketball. This roughly translates to over 35000 dots (also called pebbles, dimples, or bumps) over the total surface area of the basketball.
What is the point of those small dots, dimples, or bumps on the basketball? What are they called, exactly what is the use for them? Is that there for design or decoration? After being a little curious and researching the purpose of these dots, all this will be answered further down below.

What is the purpose of the dots on the basketball?
The purpose of the dots on basketball is not just for show or decoration but to provide the necessary grip for the basketball player to have control of the ball. The dots provide more points of contact with the hand of the player or the hardwood court and basket. This design gives maximum control possible to the player. Spalding was the first to come up with this design while everyone else followed suit.
What are those little bumps called then?There is no right terminology for these dots but you can see that they are raised small bumps that are circular and are all over the ball. The bumps on the basketball is a special design that has stayed relevant for many years coupled with the basketball material of being leather, this was the perfect duo to provide basketball players around the world with maximum control.
Basketball Design
You will see these raised pebbles on a basketball on almost every type of ball, leather, composite, and rubber. There is a reason for this and that is because it is by far the best design for a basketball.
This basketball design is efficient in being resilient to players sweating all over the ball and having sweaty hands from the vigorous play during a basketball game. There is a reason they have people who mop up the sweat during the free-throw line as these players are standing in one spot dripping in sweat, the floor would be slippery and players would get hurt.
In the case of the basketball design with all those small pebbles, there are times where the ball may need to be wiped with a towel but most often than not it does the job protecting the surface area of the ball from being wet. This prevents any slip-ups with the ball while shooting and dribbling during the game for maximum performance.
Why do basketballs have lines?
Each basketball has 8 panels that make up the basketball. Separating those panels are the lines usually black in color which is made of rubber. These lines are there to give the hand of the player grip and control of the basketball. If you notice a used worn-out basketball is harder to control without the lines, as the basketball’s grip is worn down to the lines making it one even surface. Having the lines will help the basketball player control and stop the basketball very briefly in the hand so he/she can control it.
What are the dimensions of a basketball?
A Men’s size 7 basketball is 29,5 inches in circumference and around 9.5 in diameter. It weighs 22 oz and requires anywhere from 7.5 to 8.5 PSI also know as pounds per square inch. More on these measurements and of other size balls click here!

How Many Dots Does A Basketball Have? A Quick Overview
In 1891, Dr. James Naismith invented the sport we now know as basketball. But it wasn’t until a few years later when basketball showcased its distinct ball design. It underwent different design changes over the years until the ball would eventually have those dots on the surface. But what are these dots? Also, how many dots does a basketball have?
The standard basketball has 122 dots per square inch. Take into account the standard 29.5-inch circumference of an average basketball ball and it translates to about 35,000 dots throughout the ball’s entire surface.
What are these dots called? How did the basketball look like its current design? Why is it orange? You’ll find the answers to these questions as you continue to the rest of this article.

What are the Dots on a Basketball?
All basketballs, especially those used in official matches, have dots. The basketball-making sector calls these dots ‘pebbles.’
These pebbles are no mere decorative elements. Instead, these thousands of tiny components help basketball players hold and grip the ball properly. Further, the pebbles help the ball gain enough traction when it bounces off the floor.
If these pebbles didn’t exist, basketball players would find it more challenging than intended to control the ball. The ball would also have a high chance of bouncing in different directions when dribbled, causing several disruptions during games.
What is the History of the Basketball’s Design?
Inventor Dr. James Naismith created basketball in 1891, but it wasn’t until 1894 when the sport had its official ball. So what did the players use during the sports first three years? They used a ball with enough bounce for dribbling. But the ball didn’t have the pebbles that now exist in the current basketball design.
Think of using the classic basketball as trying to hold an ice cube; the lack of friction, when in contact with non-resistant surfaces, is a recipe for disaster. The frictionless basketball would bounce in various directions as players found it difficult to control the ball.
Thankfully, Naismith knew A.G. Spalding, a close friend, and sporting goods maker. Spalding, which is known by many as the famous sporting goods brand, collaborated with the doctor to design a ball with the right amount of traction.
As the two sports experts put on their thinking caps, the dots or pebbles on the basketballs came to be.
Combined with a new, rough, and well-treated leather, the basketball used from 1894 and onwards had more traction and grip. In turn, the athletes had an easier time controlling the ball, which also made for more exciting games.
This design choice stuck to this day. The appearance of the basketball brought by the brilliant minds of Naismith and Spalding is still used by many modern sporting goods manufacturers.
Nonetheless, the quest for the ‘perfect’ ball for basketball is still ongoing. In 2001, the Spalding brand was at it again as it developed a ball with a built-in pump. This new ball has a reduced risk of leakage. Also, in 2006, the Spalding company made a new ball for the NBA. This updated design has a microfiber composite shell instead of leather.
What is the Reason for the Black Lines on Basketballs?
Like the pebbles on a basketball’s surface, the ball’s black lines have a specific purpose. These lines show players where to hold the ball for the proper grip. Further, the lines help the player grip and steer the ball better while dribbling. Again, if the ball doesn’t have pebbles or lines, controlling it would be a difficult endeavor.
Why is a Basketball Orange?
Each aspect of the basketball’s ball isn’t only for show, especially its orange color. It’s still possible to see basketballs in different colors. For example, some sports shops sell basketballs in black, blue, red, or a combination of these three colors. However, official basketball leagues only use orange basketballs because of one specific reason – visibility.
Tony Hinkle, a legendary coach of different sports, is the father of the orange-colored basketball. Before the late 1950s, basketballs used to be brown. But some players complained that the brown color would sometimes blend with the surroundings, making it difficult to keep track of the ball.
Hinkle decided to contract the help of the Spalding Company. This move turned out to be a wise decision as the two innovators transformed the old brown basketball into an orange one in 1957. But it wasn’t until the 1958 NCAA Finals in Louisville, Kentucky when the orange basketball first debuted in an official match.
What are the Sizes of Basketballs?
Although all basketballs have the same shape, you can still find different sizes for these balls across the market. Here’s a quick guide for the different basketball sizes:
- Size 3: 22.5-inch circumference for novelty use.
- Size 5: Standard basketball size for 5- to 8-year-olds. It has a 27.5-inch circumference.
- Size 6: Standard basketball size for 9- to 12-year-olds. It has a 28.5-inch circumference and is mostly used by males.
- Size 7: The official NBA size. It has a 29.5-inch circumference and is used by players 13 years and over.
Final Words
The dots or pebbles on the basketball are about 35,000 in number encompassing the 29.5-inch circumference of the ball. These components allow players to control and grip the ball properly. Otherwise, the basketball would have a high risk of bouncing in different directions when dribbled.
How many pimples a basketball has: sly2m — LiveJournal
He used to have a calculator, and he calculated everything,
and now he has WolphramAlpha, so now he’s generally . ..
Wandered into Wikipedia, started reading about one thing, then follow the links about something else, and as usual - let's go.
I stopped, as usual, at a completely abstract article, it turned out to be an article about a basketball.
An "interesting fact" is given at the very end - Basketball has an average of 9 342 059 pimples.
And even a link to the source of this interesting fact is provided, leading to the site allexperts.com, where experts gather to give various facts a scientific explanation.
This number alerted me right away. It can be seen that the author of the article has a poor idea of what a million is (especially nine million).
A million is really very, very, very much. Really a lot. Seeing a million things at once is extremely difficult.
Do you think there are "a million" stars in the sky? An-no. Barely 6000 will be typed, visible to the naked eye.
A million can be seen at once and in one place, if, say, you cover the floor in a large empty room (for example, a hall) with newspapers, and then stand in a corner and look around the room. In this case, approximately (very approximately) a million newspaper letters will be visible. Can you imagine what a huge pile it is!
Let's move on to the pimples. There can't be 9 million of them, compare the size of the hall and the surface of a basketball.
From the same wiki article, we learn that the circumference of the official basketball (size 7) for men's competitions is 750-780 millimeters. But I no longer believe the author of the article, since he writes such nonsense, he went google. No, indeed, an average of 765 millimeters.
Go to WolphramAlpha and write "sphere circumference 765 millimeters", only in English, of course - "sphere circumference 765 millimeters". All this, of course, for the lazy. For those who have forgotten how to calculate the radius from the circumference, and the surface area from the radius.
For those lazy ones, it will be convenient to write at the very bottom of the page - the surface area is approximately equal to 186 283 mm 2 .
Now we find a high-resolution photo of a basketball in Google:
We mark a square on it (of course, such an uneven square) with sides of about 8x8 pimples. Those. it turns out that in a square of 25x25mm we have 64 pimples.
Well, on the total surface of 186 283 mm 2 we get ~19 075 pimples. And this is not counting the black stripes, in this calculation we will assume that the pimples are evenly distributed over the surface of the ball, not taking into account the black grooves-stripes and the logo.
Well, where are nine million (9,342,059) and where are nineteen thousand (19,075)?
Just think, 500 times the error came out...
If anyone is registered on Wikipedia, please correct it there. And then I have a principle - never edit either a wiki, or a lurka, or any other online encyclopedia.

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.
- 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.
