Regulation size of basketball may vary depending on official leagues. Here are some of the NBA’s basketball regulation size rules for certain leagues:
FIBA (International Basketball Federation)
The size rule of basketball for FIBA is extremely strict. It must be size 7, and it must have the presence of the serial number and the name of the manufacturer.
The circumference of the balls is 30.7 inches, while the weight ranges from 567 to 650 gm. When these balls drop from 70.8 inches, they might bounce to a height of 51.2 inches or even more.
These FIBA-approved basketballs must pass various stringent tests (For instance, valve and heat tests).
Juniors and Youngsters
For the juniors, the recommended circumference of basketballs is 27.75 inches (size 5), while their weight is approximately 18 oz.
For children younger than 7, choosing balls with a circumference of 22 inches and a weight of around 8 oz is recommended.
National Basketball League
Spalding produces NBA basketballs. Their official size for men’s tournaments must be 29.5 inches in circumference.
With 22 oz weight, these balls might be inflated with pressure from 7.5 to 8.5 psi. They are size seven and are made from orange leather with black lettering.
For the women, the basketball size is a bit different. These balls are still produced mainly by Spalding but are smaller (size 6). Their circumference will range from 28.5 to 29 inches, weighing 18 to 20 oz.

When they drop from 6 feet, their bounce height could be between 51 and 56 inches.

Indoor vs. Outdoor Basketballs
Basketballs used indoors and outdoors might vary in their materials.
Basketballs used outdoors and indoors might vary in their materials. An indoor basketball is made of full-grain leather, while an outdoor one is made from rubber.
Although indoor basketballs may feel smooth when touching, they will become somewhat broken in and easier to grip after a few uses, like baseball mitts.
You should not use leather basketballs as the concrete surface of an outdoor court may cause the leather to wear and roughen, eventually ruining your ball’s grip.
Some indoor basketballs are made from synthetic or composite leather. As for the pros, they won’t be broken in like regular leather balls. But their quality is inferior.
Outdoor basketballs, also known as “street” balls, feature a rubber surface, allowing them to absorb the rougher surface of a concrete court without losing the ball’s grip.
Rubber balls are also good options for beginners as it is the most straightforward basketball to control.
What Are Materials Used To Make Basketball?
