The purpose of the dots: to create friction, aiding grip and dribbling
The game of basketball has come a long way since its inception in 1891 by James Naismith, a charming, well-mustachioed P.E. teacher. In the early days of the sport, teams used soccer balls, which, combined with the oil-polished hardwood gym floors, made it challenging for players to maintain their grip on the ball. Naismith and sporting goods maker A.G. Spalding collaborated on a new design for a ball that would be easier to handle. They decided that the ball needed to be larger and have an added source of friction.
The dots on a basketball, also known as "pebbling," serve the purpose of creating friction, aiding grip, and enhancing dribbling capabilities. These raised dots increase the number of contact points with the court, increasing friction and preventing the ball from slipping out of the player's hands. The dots also help create a uniform surface, improving the ball's performance during shooting and dribbling.
The process of creating these dotted basketballs involves treating leather with a specific tanning process, adding essential oils to make the leather stickier and easier to grip. The leather is then taken to a special press, where dots are embossed to create each individual pebble. This process was pioneered by the Horween Leather Company, which has been manufacturing the NBA's speckled leather for over 60 years.
The standard size for a basketball is 29.5 inches in circumference, with 122 dots per square inch, resulting in over 35,000 dots on the entire surface. These dots are typically arranged in a regular pattern and made of rubber or other comfortable grip materials. They are an essential part of the basketball's construction, providing durability and making the ball easier to control and dribble.

The history of the dots: introduced in the 1950s to combat slippery soccer balls
The introduction of dots on basketballs dates back to the early days of the sport in the late 19th century. In 1894, basketball teams were using soccer balls, which had slick surfaces. When combined with the oil-polished hardwood gym floors, this created a slippery playing experience, making it challenging for players to handle the ball effectively.
James Naismith, the inventor of basketball, collaborated with his friend and sporting goods maker, A.G. Spalding, to design a new ball that would improve the players' ability to grip and control it. They decided that the ball needed to be larger and have an added source of friction. This led to the introduction of the dots, also known as "pebbles," on the basketball's surface.
The Horween Leather Company, which has been manufacturing the NBA's speckled leather for over 60 years, uses a specialized process to create this unique texture. This process involves various steps, including inspecting, baiting, pickling, tanning, re-tanning, drying, and grading the leather. Finally, the leather is embossed with dots to create each individual pebble, providing extra points of contact and enhancing friction.
The pebbling on a basketball helps players grip the ball and improves their control during dribbling and shooting. While the dots do provide additional traction, they cannot completely prevent slippage, especially when the ball becomes sweaty during gameplay. Over time, the pebbling on a new basketball wears down and becomes less pronounced, but it remains an essential part of the ball's construction, contributing to its durability and performance.

The name of the dots: officially pebbling, also called pebbles
The many dots covering a basketball are officially called pebbling, or pebbles. The dots are raised, textured surfaces on the ball that help players grip it and provide a uniform surface for shooting and dribbling. The dots are typically arranged in a regular pattern and are made of rubber or another material that is comfortable to grip.
The origin of pebbling can be traced back to the early days of basketball when teams were using soccer balls. The slick surface of the soccer ball, combined with the oil-polished hardwood gym floors, created a slippery playing experience. Players struggled to handle the ball and focus on the game.
James Naismith, the inventor of basketball, collaborated with his friend and sporting goods maker, A.G. Spalding, to design a new ball that would be easier for players to handle. They decided that the ball needed to be larger and have an added source of friction. This is where pebbling comes in. The dots, combined with a rough, well-treated leather surface, create more points of contact with the court, enhancing friction.
The first pebbled Spalding basketball was a success, and players could dribble the ball without it slipping out of their hands. The Horween Leather Company has been manufacturing the NBA's pebbled leather for over 60 years. The process of creating this leather involves a series of steps, including inspecting, baiting, pickling, tanning, re-tanning, drying, and grading horsehide leather. At the end of this process, the leather is taken to a special press, where dots are embossed to create each individual pebble.

The number of dots: over 35,000 on a standard basketball
The standard size for a basketball is 29.5 inches in circumference. On average, a basketball has 122 dots per square inch, which means there are over 35,000 dots on its entire surface. These dots, also known as "pebbles", are added to the ball to improve a player's grip. The raised dots give players a better way to hold onto the ball, especially when it is new and the pebbling is more pronounced.
The dots were first added to basketballs in the 1950s by the Horween Leather Company, which has been manufacturing the NBA's speckled leather for over 60 years. The company's unique process of making NBA-certified leather involves inspecting, baiting, pickling, tanning, re-tanning, drying, and grading all the horsehide leather. At the end of this process, the leather is taken to a special press, where dots are embossed to create each individual pebble.
The addition of these dots solved a problem that players were facing in the early days of basketball when teams were using soccer balls. The slick surface of the soccer ball, combined with the oil-polished hardwood gym floors, made it difficult for players to handle the ball properly. The dots, combined with rough, well-treated leather, create more points of contact with the court and enhance the amount of friction, allowing players to dribble the ball without it slipping out of their hands.

The manufacturing of the dots: created through a complex leather tanning process
A basketball is made from black butyl rubber, which gives the ball its bounce and ability to retain air. The inner bladder is created by melting the rubber into flat panels, which are then attached to form the basketball shape. The bladder is then inflated and left for 24 hours to ensure its correctness. Polyester or nylon threads are then wrapped around the inner bladder to create a spherical shape and prevent deformation.
The cover of the basketball is made from different materials, with high-quality basketballs featuring a leather cover. The leather goes through a complex tanning process to prepare it for use on the basketball. First, the hides are cleaned of dirt, blood, salt, and hair. They are then soaked to remove any remaining excess salt or dirt, and all non-leather-making components are removed to prepare for the production of clean and flat pelts.
The next step is the tanning process, which turns the hides into leather. Tanning changes the chemistry inside the leather fibres, making it more durable and preventing the breakdown of enzymes from bacteria and fungi. There are several methods of tanning, including vegetable tanning, which is the oldest method and uses extracts from wood and nuts of trees and shrubs. This method produces distinctive and high-quality leather but takes longer than other processes.
Another method is chrome tanning, which involves soaking the hides in baths containing acidic salts and chromium tanning agents. The acidity of the bath is decreased until the hides absorb the chromium agents. This method is faster and less labour-intensive than vegetable tanning, and the resulting leather is consistent and durable.
Once the leather is tanned and cut to the required thickness, it is ready to be used for the basketball. The material is unfolded and cut into six panels that will be wrapped around the ball and stitched together. If the manufacturer wishes to add decals or graphics, they are applied by hand at this stage, usually through stickers that are glued to the ball. After the leather patterns are injected, the stickers are removed, leaving only the desired graphics on the ball.
