NBA Basketballs
The NBA uses a size 7 basketball for all game play. The weight of the ball is 22 ounces with a circumference of 29.5 inches. That size ball is also used by FIBA for international competition. Women’s basketballs have a slightly smaller circumference of 28.5 inches.
The Spalding NBA Official Game Ball
The Spalding NBA Official Game Ball is NBA’s official basketball. Made of leather and measuring 29.5 inches in circumference, the basketball has an inner rubber bladder that is inflated to a pressure of 7-9 psi. The ball is broken in or “seasoned” before each game by rubbing its surface with a grindstone.
The Wilson Evolution
The Wilson Evolution is the official game ball of the National Basketball Association (NBA). It is manufactured by Wilson Sporting Goods and was introduced in the 2006-07 NBA season, replacing the Spalding EFlevation.
The Wilson Evolution is composed of an innovative material that promises softer touch and feel, consistent bounce, and enhanced durability. The ball is made of a microfiber composite leather that Wilson touts as being 25% more responsive than traditional leather. The ball has a full-grain leather cover with perforated panels for better grip and feel. It also has a butyl bladder for improved air retention.
The Wilson Evolution was designed to meet the NBA’s exacting specifications for size, weight, bounce, and shape. The ball is 29.5 inches in circumference (size 7), which is the standard size for all men’s basketballs. It weighs 22 ounces, which is also the standard weight for all men’s basketballs. The ball has a unique 13-panel design that helps it retain its round shape after extended use.
The NBA switched to the Wilson Evolution because players were looking for a softer, more responsive basketball that would provide better grip and feel on the court. The new material also promised to be more durable than traditional leather, meaning that balls would not need to be replaced as often. So far, the Wilson Evolution has been well-received by players and fans alike and it looks like it will be the official game ball of the NBA for many years to come.

Why the NBA Uses a Specific Size Ball
The NBA uses a size 7 basketball for all of their games. This might seem like a random number, but there’s actually a lot of science that goes into the size of the ball. The size of the ball affects how easy it is to shoot, how well it bounces, and how fast the game is played. Let’s take a closer look at why the NBA uses a size 7 basketball.
The Diameter of the Ball
The official diameter of a basketball used in the NBA is 9.43 inches. This is a bit larger than the ball used in college basketball, which has a diameter of 9.25 inches. The smaller ball is said to be more difficult to handle, and that’s one reason why the NBA uses the larger size.
In addition to the size of the ball, there are also differences in the weight and material used. A regulation NBA basketball weighs 22 ounces, while a college ball weighs 20 ounces. The NBA ball is also made of synthetic leather, while the college ball is made of genuine leather. These subtle differences make a big difference to players, and they help to give the NBA an edge in terms of skill and competition.
The Circumference of the Ball
The circumference of the ball is 29.5 inches, which is only 1/2 an inch larger than a regulation size 28.5-inch basketball. The NBA goaltending rules state that the ball must pass through the basket from above and completely drop through the bottom of the net. The ball is also newer and made of synthetic material that helps it grip the air better and makes it easier for players to handle.
The Weight of the Ball
The weight of the ball is another big consideration. A ball that’s too light will be easily swatted away by defenders. Conversely, a ball that’s too heavy will be difficult to control and make shooting harder than it has to be. The official NBA weight for a basketball is 22 ounces, or 1.3 pounds.
