How big is a basketball?

The official size of a basketball used in the NBA is 29.5 inches in circumference. However, the size of a basketball will change based on the level of play. For example, a ball used in junior high school basketball may be 27.5 inches in circumference. The size of the ball is not the only thing that can vary, as the weight of a basketball can also range from 18 to 22 ounces, with the latter the required weight of all NBA basketballs.

What size is a women’s basketball?

A women’s basketball is slightly smaller than a men’s basketball. The official size of a women’s basketball is 28.5 inches in circumference, compared to the men’s 29.5 inch basketball. The difference may seem small, but it can make a big difference on the court. A smaller ball is easier to handle and control, and it also bounces more smoothly.

The evolution of the NBA basketball ball

What size is a basketball rim and backboard?

The basketball rim is 18 inches in diameter and is attached to a backboard that is 6 feet wide and 3.5 feet tall. The basketball hoop is set at a height of 10 feet for both men’s and women’s games. The basketball rim is made of metal and has a standard size of 18 inches in diameter.

There are also rims that are made for children that are smaller in diameter, usually between 14-16 inches. The basketball rim is considered an important part of the game and players must be able to shoot the ball through the hoop from different distances and angles in order to score points.

What are the dimensions of a basketball court?

The dimensions of an NBA basketball court are 50 feet wide by 94 feet long. The court is divided into two halves by the center circle, and each half is further divided into three sections by the free-throw line and the quarter circle.

NBA court dimensions have not changed much over the last 80-plus years.

Free throw line distance

The free-throw line is located 15 feet from the backboard.

Three-point line

The NBA three-point line distance varies by where you are on the court. It is 22 feet from the hoop in the corners and 23 feet 9 inches from the hoop at the top of the arc.

Indoor vs outdoor basketballs

There is a difference between indoor and outdoor basketballs.

Outdoor basketballs are generally made of rubber to withstand the harder concrete surface, while indoor basketballs are made of synthetic leather or composite materials to give the ball a softer feel.

Rubber changes the feel and bounce of the ball, so indoor and outdoor basketballs feel and perform differently. Outdoor balls not only need to withstand more wear and tear, but they also need to be able to bounce on a variety of surfaces and withstand weather conditions.


Whether you’re looking for a basketball for a man, woman, your young child, or a gift for the gym rat that lives on the court, there are many sizes and styles of balls available online that will be sure to satisfy their needs.
