What Is The Official Nba Ball Size?

The Official NBA Ball Size is a size 7 basketball. It is 28.5 inches in circumference and weighs 22 ounces.

Introduction

The official NBA ball size is 29.5 inches in circumference. That’s the same size as a women’s basketball, but smaller than a men’s ball, which has a circumference of 30 inches. The NBA has used this ball size since 2006, when it was first introduced.

The reason for the change was twofold: to help players with their shooting, and to increase scoring. The smaller ball was easier to control and shoot, and it resulted in more points being scored.

There are some drawbacks to the smaller ball, though. It can be more difficult to handle, and it doesn’t bounce as well as a larger ball. But overall, the NBA is happy with the decision to switch to a smaller ball, and there are no plans to change back.

The official NBA ball size is 29.5 inches in circumference, or about three inches smaller than a regulation volleyball.

The Official NBA Ball Size for Women

The basketball used in women’s NBA games is 28.5 inches in circumference around the widest part of the ball, which is about 11.4 inches in diameter. This size is also used for all levels of women’s basketball up to the college level. The size 6 ball, which is what most elementary school children use when they start playing basketball, has a circumference of 28.5 inches as well.

Why the NBA Uses a Different Ball Size for Men and Women

The basketballs used in the NBA have a circumference of exactly 29.5 inches (74.9 cm). They weigh 22 ounces (623 grams). These are the official ball specifications set by the National Basketball Association.

Interestingly, the women’s game also uses a different size ball. The WNBA uses a smaller ball that has a 28.5-inch (72.4 cm) circumference and weighs 20 ounces (567 grams).

The main reason for this difference is that the women’s game is played on a smaller court. The WNBA court is 84 feet (25.6 m) long, while the NBA court is 94 feet (28.7 m) long. This means that the players need to be able to handle the ball more quickly, and the smaller ball makes it easier to do so.

This is the size that has been used by the league for many years now, and it doesn’t appear that this will be changing anytime soon. So, if you’re looking to buy an NBA ball, make sure that it is 28.5 inches in circumference.
