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? Quick Overview
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.

Respect! You can't sit on an inflated basketball and hit it with your feet, like a football, with the force of throwing a ball on a hospital object - as a result of this ball, it quickly loses its shape and comes into disrepair.
Inflate a basketball in the appropriate manner: put 1-2 drops of special oil on the opening of the nipple or the neck, take the ball by the panel, where the nipple is located, insert it into the new neck, inflate the ball to the value indicated in the vice tables.
We strongly recommend vicarious oil. Special oil is not only ahead of valve slippage and nipple walls, but it also makes the material of the nipple more elastic, protecting it from drying out.
The head is also due to a special buti for inflating balls, and the tip of the head is due to buti equal, smooth, without sharp edges and burrs.
ATTENTION! Always vicorate the vowels for the nipple or the ball, in the other case, you risk damaging the nipple and lose it without a ball.
The amount of grip that is recommended for balls made of different materials and in different types of winding:
| Riven gri | Recommended vice (bar) | Recommended vice (psi) |
| Basketball rubber balls, size 5-7 | 0. 7-0.9 | 10-13 |
| Basketball rubber balls, size 3 | 0.6 | 8-9 |
| Basketball balls made of natural and synthetic skins, size 7 | 0.7-0.9 | 10-13 |
| Basketball balls with natural and synthetic skins, sizes 5 and 6 | 0.7-0.8 | 10-12 |
It is recommended to check the vise in the balls after the help of the monometer.
Rolling the ball creates a pressure and over the world stretching tension on the materials, from such preparations of the ball, with which the term of the ball's service is very fast.
Rolling the ball also negatively affects the game characteristics of the ball, first for everything on yoga.
Take care of that sight.
- After skin irritation wipe the ball with a damp cloth. At the time of the strong, vicorist fabric, soaked in a warm miles pink. Do NOT at any time do not beat up abrasive cleaning cats, and also take care of the retailers and aggressive speech.
- Let the ball dry naturally. If the ball is already wet, wipe it with a soft cloth. Dry the ball in a well-ventilated room, give it heat, at a temperature of + 20-25 ° C and a moisture content of 60-65%. Avoid direct sleepy changes and do not dry the ball nearby, or on the surface of the scorching devices. Trivals of mud, water, increased temperature lead to an increase in the physical powers of the ball and, as a result, its game characteristics, short term of service.
- It is recommended to store the balls in a dry ventilated area at a temperature of 5-25 C and an air humidity of 50-80%. The balls are due to protection from falling direct sleepy exchanges, diva, gases and chemical speeches.
- Balls made of synthetic and composite skins should be taken away and transported in a puffed-up look. In the other case, the deformation of the material of the coating and the opening of the panels is possible.
Thank you for the miraculous smile and brilliant wins! :)
Ball inflation pressure
Ball inflation pressure
A properly inflated ball is the key to a good game and durability.
If the ball is not sufficiently inflated, then this will entail a low rebound, poor handling, and an incorrect flight path. If the ball is pumped over, it can burst, change shape, cause pain during the game, and even cause injury.
First of all, when buying, carefully check the ball for mechanical damage, whether the ball is new and how it is packaged. Most often, the cause of the pressure drop in the ball is a damaged nipple. If you purchased the ball in a deflated state, then be sure to inflate it according to the instructions, checking the pressure, and leave the ball overnight. Check the pressure again the next day. If you bought the ball in an inflated state, then leave it for a day and see if it went down during this time. You can also use the "old Russian way" to determine the health of the nipple. To do this, moisten your finger and attach to the nipple. A properly functioning nipple will not form bubbles. We draw your attention to the fact that if you purchased the ball and used it, then the guarantee for such a ball remains only after the provision of an expert opinion.
Back to pressure... The pressure in a ball depends on what sport the ball is for, what size it is, and what level of play it is. Different manufacturers measure pressure in different units, psi (pounds per square inch), bar (pressure unit approximately equal to one atmosphere), kgf / cm² (one kilogram of force per square centimeter), kPa (kilopascal). Pay attention to this!
The pressure in the ball is strongly influenced by the ambient temperature and atmospheric pressure. If we recall physics, then at high temperatures the substance expands, and at low temperatures, on the contrary, it decreases. So if, in winter, we pump up the ball on the street at -10 to the desired pressure, then after we bring the ball into a warm room, the pressure in it will increase slightly. This is true, for example, for soccer balls for games in winter. Therefore, it is better to inflate the ball directly where games or training are planned. If the operating pressure recommended by the manufacturer is not observed, the performance of the ball will be significantly worse and the ball will become unusable very quickly.
