A typical basketball

A basketball is a spherical inflated ball used in a game of basketball. Basketballs typically range in size from very small promotional items only a few inches in diameter to extra large balls nearly a foot in diameter used in training exercises to increase the skill of players. The standard size of a basketball in the NBA is 9.5 to 9.85 inches (24.1 to 25.0 cm) in diameter.[1]

Nearly all basketballs have an inflatable inner rubber bladder, generally wrapped in layers of fiber and then covered with a tacky surface made either from leather (traditional), rubber, or a synthetic composite. As in most inflatable balls, there is a small opening that allows the pressure to be increased or decreased.

The surface of the ball is nearly always divided by "ribs" that are recessed below the surface of the ball in a variety of configurations and are generally a contrasting color. An orange surface with black ribs and a possible logo is the traditional color scheme of basketballs but they are sold in various colors.

Balls are generally designated for indoor (generally made of leather or absorbent composites), or all-surface use (generally made of rubber or durable composites, also known as Indoor/Outdoor balls). Indoor balls tend to be considerably more expensive than all-surface balls due to cost of materials. In addition, brand new all-leather indoor balls must be "broken in" first to achieve optimal grip before use in competition. The abrasiveness of asphalt and the dirt and moisture present in an outdoor setting will usually ruin an indoor ball within a very short period of time, which is why an indoor/outdoor ball is recommended for recreational players.

Aside from the court and the baskets, the basketball is the only piece of equipment necessary to play the game of basketball. During the game, the ball must be bounced continuously (dribbling), thrown through the air to other players (passing) and towards the basket (shooting). Therefore, the ball must be very durable and easy to hold on to. The basketball is also used to perform tricks (sometimes called freestyling), the most common of which are spinning the ball on the tip of one's index finger, dribbling in complex patterns, rolling the ball over one's shoulder, or performing aerobatic maneuvers with the ball while executing a slam dunk, most notably in the context of a slam dunk contest.


A historic basketball.

In early December 1891, the chairman of the physical education department at the School for Christian Workers (now Springfield College) in Springfield, Massachusetts, instructed physical education teacher James Naismith, known to many as the inventor of basketball, to invent a new game to entertain the school's athletes in the winter season. Naismith assembled his class of 18 young men, appointed captains of two nine-player teams, and set in motion the first ever basketball game, played with a soccer ball and two peach baskets tacked to either end of the gymnasium.

The first purpose-built basketballs were made from panels of leather stitched together with a rubber bladder inside. A cloth lining was added to the leather for support and uniformity (identity). A molded version of the early basketball was invented in 1942. From 1967 through 1976, the American Basketball Association (ABA) used a distinctive red, white and blue basketball that is still seen from time to time. For many years, leather was the material of choice for basketball coverings, however in the late 1990s, composite materials were put forth and have rapidly gained acceptance in most leagues due to their superior performance in harsh outdoor game conditions.

Notable basketball manufacturers[edit]


A Spalding basketball

Spalding was the first company to produce a basketball for official use. Company founder A.G. Spalding made the first dedicated basketball in the last years of the 19th century at the behest of James Naismith. It has produced basketballs since that time and has produced the NBA’s official game ball since 1983. The company also produces a wide variety of balls for the consumer market.

In June 2006, the NBA announced that Spalding would be introducing a new official game ball for play beginning in the 2006 season. It was made from a microfiber composite with moisture management that was supposed to provide better grip and feel. However, there were several complaints about the new basketball. Many players complained that the new ball was slippery, hard to hold and that the increased friction caused cuts on player's hands. Many elite players called for the NBA to bring back the old ball, even bringing a grievance to the National Labor Relations Board to revert to the original leather ball. On December 11, 2006, NBA commissioner David Stern announced that the NBA would switch back to the old leather model starting at the beginning of 2008. In 2008, Spalding became the Official Basketball Provider of the Ball4Real World Tour.[2] Horween Leather Company's leather is used to make National Basketball Association basketballs.[3]

Spalding became the new supplier for NBL (Australia) in 2010.[4]


Molten GL7 basketball

Molten, a Japanese sporting goods manufacturer, has the current contract to provide game balls for:

Through the 2006–07 season, it had to provide balls for both Europe-wide competitions organized by Euroleague Basketball (company), the Euroleague and ULEB Cup (now the Eurocup). However, Euroleague Basketball has now signed Nike as its ball provider.[5] Molten's top-of-the line product is the GL7/GL6, a leather ball with a distinctive 12-panel design, a high-density cushioning foam below the surface and special soft rubber seams, a flatter pebbled finish providing increased contact area and a flattened seam between the panels (called a "Full-Flat Seam"). Molten also produces a wide variety of balls at all price points for the consumer market.


Wilson Solution basketball

Wilson's top-of-the-line product is the SOLUTION ball, named for its ability to absorb moisture over the course of a game and retain its grip. The ball is the official ball of all NCAA postseason tournaments, most notably the men's and women's Division I tournaments, and is used by many NCAA teams during the season as well by many high school leagues. Like Spalding, Wilson produces a variety of balls for the consumer market as well. Since 2012 Wilson's SOLUTION ball is the official ball of the 2nd Bundesliga in Germany.[6]


Rawlings TEN basketball

Rawlings has manufactured basketballs since 1902. The company is known for producing a 10-panel ball (known as the TEN), along with traditional 8-panel balls. The TEN basketball is the official ball of the Amateur Athletic Union and the "Gus Macker", the largest 3-on-3 basketball tournament in the United States.[7]


Nike 4005 basketball

Nike, as noted earlier, now has the contract to produce balls for the Euroleague Basketball Company (including the Euroleague). In the Philippines the NCAA and UAAP use the Nike 4005 Official Tournament Balls.
