Basketball enjoys a huge fan following all over the world. It was invented in 1891 in Springfield, Massachusetts, by Canadian physical education instructor James Naismith. The first basketball game was played using a soccer ball. In 1894, the soccer ball was replaced by a ball made by Spalding. The first purpose-built basketballs were made from panels of leather stitched together with a rubber bladder inside. Over the years, the ball went through several modifications, and in 1942, a moulded version of the early basketball was invented.

What You'll Learn
Early basketballs were made of laced leather
Basketball has come a long way since its inception in 1891 when the game was first played with a soccer ball. Early basketballs were made of laced leather, with the first basketball being manufactured in 1894. This ball was 32 inches (81 cm) in circumference, about 4 inches (10 cm) larger than a soccer ball, and weighed less than 20 ounces (567 grams). The leather used for these early basketballs was susceptible to moisture damage, which led to the adoption of composite materials in the 1990s.
Leather continues to be a preferred material for basketball construction even today, with the NBA adopting full-grain leather balls as its official balls in 1983. The Horween Leather Company in Chicago is the exclusive supplier of leather for the NBA Game Ball. The leather-making process involves sorting leather pieces by the clarity of their grain, thickness, and size. The leather is then coloured and preserved in tanning drums. It undergoes a double drying process and is finally graded, trimmed, packaged, and shipped to China for cutting and sewing.
The shift to composite materials in the 1990s improved the durability of basketballs, especially in harsh outdoor playing conditions. Synthetic materials also provided more consistency in ball performance. This transition from leather to composite materials was part of the ongoing evolution of basketball design, which included innovations such as microfiber covers and updated pebbling patterns to enhance grip and control.
The first molded basketball, introduced in 1948, eliminated the need for laces. This ball had a construction and size of 30 inches (76 cm) that were ruled official in 1949. While the materials and designs have evolved, the traditional colour scheme of a basketball remains brownish with an orange surface, black ribs, and a logo.

Leather was phased out due to its limitations when exposed to moisture
Basketballs have undergone a significant evolution since the sport's inception, with the materials used for their construction playing a pivotal role in this transformation. Early basketballs, dating back to the late 19th century, were predominantly crafted from leather. This choice of material was a natural progression from the soccer balls initially used in the earliest basketball games.
Leather, however, presented several limitations, especially when it came to moisture exposure. Leather is a natural material that can absorb water, leading to changes in weight, texture, and overall performance. This becomes particularly relevant when considering the impact of sweat and humidity during intense basketball games. The moisture absorbed by the leather could affect the ball's grip, making it slippery and challenging to control.
Additionally, leather's tendency to absorb moisture could result in uneven weight distribution within the ball. This inconsistency in weight could influence the ball's trajectory, making it unpredictable for players during shots, passes, and dribbles. The moisture could also accelerate the breakdown of the leather over time, reducing the ball's durability and necessitating more frequent replacements.
To address these limitations, a shift occurred in the 1990s, with basketball manufacturers embracing composite materials. These synthetic alternatives, such as synthetic rubber, offered enhanced durability and performance, especially in harsh outdoor playing conditions. The introduction of microfiber covers further improved grip and control, providing players with a more consistent and reliable playing experience.
The evolution from leather to composite materials in basketball construction was a response to the inherent limitations of leather when exposed to moisture. This transition not only improved the performance and consistency of the ball but also contributed to the sport's growing popularity and the development of professional leagues.

In the 1990s, basketballs started to be made from composite materials
Basketballs have undergone a series of design changes since the game's inception in 1891. The sport was created by James Naismith, a physical education teacher at the School for Christian Workers, now known as Springfield College, in Springfield, Massachusetts. The first basketball game was played with a soccer ball, and the first dedicated basketball was manufactured in 1894. This ball was made of laced leather and weighed less than 20 ounces.
Over time, basketballs began to be made from different materials, with companies like Spalding, Molten, Wilson, and Nike becoming prominent manufacturers. In 1948, the first molded basketball was introduced, eliminating the need for laces. This ball had a construction and size of 30 inches in circumference, which was ruled official in 1949.
The standardization of inflation pressure has been another significant development in the evolution of basketballs. The NBA mandates a pressure range of 7.5 to 8.5 PSI, ensuring a consistent bounce and feel across all basketballs used in the league. This standardization contributes to fair play and helps maintain the integrity of the game.
Today, most basketballs are inflatable and made from leather, synthetic composite, or rubber. The traditional color scheme remains brownish with an orange surface, black ribs, and a logo. The balls undergo multiple quality assurance tests to ensure they meet the required standards in terms of inflation, circumference, rebound, and consistency.

Full-grain leather balls were adapted by the NBA in 1983
The game of basketball was invented in 1891 by James Naismith, a physical education teacher at the School for Christian Workers, now known as Springfield College. The first basketball game was played using a soccer ball, and the first dedicated basketball was manufactured in 1894. It was made of laced leather and weighed less than 20 ounces.
Over the years, the design of basketballs has evolved, with the introduction of different materials and construction techniques. In 1948, the first molded basketball was introduced, eliminating the need for laces. This was followed by the development of the first basketball specifically for indoor use in 1942 by Spalding, a company founded by former baseball player A.G. Spalding.
In 1983, the NBA adapted Spalding's full-grain leather ball as its official ball. Leather was a traditional material for basketball coverings, and Spalding had been producing the NBA's official game ball since then. The leather used for the NBA Game Ball comes exclusively from the Horween Leather Company in Chicago, one of the oldest leather tanneries in the United States.
The process of making the NBA Game Ball involves sorting leather pieces by the clarity of the grain, thickness, and size. The chosen pieces are then colored and put into tanning drums for preservation and tanning. The leather is stamped with a 1,000-ton press to create the distinct pebbling on basketballs. The embossed leather is then painted with lighter coats to achieve the desired combination of color, durability, and feel.
After the leather is prepared and assembled, the basketballs undergo multiple quality assurance tests. These tests include inflation, measurement, and rebound tests to ensure consistency in form and performance. The final step is "waking the windings," where the balls are rebounded at 20 miles per hour, 50 times. Once they pass these tests, the basketballs are delivered to the teams and are ready for gameplay.

Synthetics and rubber are also used to make basketballs
Basketballs have come a long way since the game was first played in 1891 using a soccer ball. The first dedicated basketball, manufactured in 1894, was made of laced leather and weighed less than 20 ounces. Over time, the design of basketballs has evolved, with different materials being used to improve performance and durability.
Today, basketballs are typically made from synthetic rubber, rubber, composite, or leather. The use of synthetic materials and rubber in basketball construction offers several advantages over traditional leather. Synthetic materials, for example, are more durable than leather, especially in harsh outdoor playing conditions. This makes them ideal for withstanding the wear and tear of outdoor courts and blacktop playgrounds. The shift to synthetic materials in the 1990s also brought about more consistency in ball performance.
The outer covering of a basketball is made from these modern materials, while the inner construction consists of a bladder and a carcass. The bladder, which holds air, is made of butyl rubber, ensuring the ball remains inflated during play. The carcass, meanwhile, provides structure and shape to the ball.
While leather basketballs are still used, they are now often reserved for official game balls, such as the NBA's official game ball, which has been produced by Spalding since 1983. The leather for these balls undergoes a rigorous three-week process, including sorting, colouring, tanning, stamping, painting, and drying. The balls are then inflated and go through multiple quality assurance tests to ensure they meet the required standards for circumference, rebound, and consistency.
