How Much Does a Basketball Weigh: Find Out Here

How Much Does a Basketball Weigh

There are many things to learn when it comes to basketball. Apart from the game itself that we love to watch, we still need to know some things, especially if we plan to play ourselves.

We can learn about the basketball pitch, the rules and regulations of the game, and even more about the ball itself. The ball used in basketball is unique, like the material, design, and weight.

Weights of Different Basketballs

There are different types of balls used for basketball and some vary according to the type of competition they are used in. NBA, WBNA, and other governing bodies usually have their standard ball weight for competitions.

NBA Standard Basketball Weight

The NBA has an official specification of how their balls should be, and there’s a constant weight and size that must be applied to every ball that will be used in the competition.

An NBA-approved ball is 29.5 inches, has a circumference of 75 inches, and weighs 1.4 pounds. The air pressure required to inflate the ball is 7.5 to 8.5 pressure per square inch.

WNBA Standard Basketball Weight

The ball used by the Women’s National Basketball Association isn’t the same as the NBA-approved ball.

The NBA ball is 29.5 inches and weighs 1.4 pounds. However, the WNBA ball has a smaller size and weighs 1.1 pounds.

NCAA Standard Basketball Weight

The NCAA typically uses Wilson basketballs. The balls produced by Wilson are slightly different from the ones produced by the NBAs Spalding Basketball.

A proper NCAA men’s ball has a 30-inch circumference and weighs 1.4 pounds. The NCAA women’s ball is 29 inches in circumference and weighs 1.25 pounds.

FIBA Standard Basketball Weight

Molten produces the balls used by FIBA. The balls are large compared to the NBA balls. 

The Molten ball for men has a circumference of 30.7 inches compared to the NBA with a circumference of 29.5 inches. The women’s ball also has a circumference of 29 inches. 

However, despite the increase in the size of the ball,  they still weigh less than the NBA standard basketballs.

Standard Youth Basketball Weight

The basketball used by the junior leagues is different from those used in the professional leagues.

Professional league basketballs fall under the 6 and 7 size categories, and they measure between 28.5 to 29.5 inches in circumference and weigh between 1.25 to 1.38 pounds.

Youth basketballs fall within the size five range. They have a circumference of 27.5 inches and can weigh between 1.06 to 1.25 pounds.

Different Weights and Sizes of a Basketball

Just like clothes come in different sizes and weights, the same applies to basketballs. 

There are different sizes and weights of basketball, and they are grouped into named classes based on their measurements.

Size 7

Basketballs that fall under size 7 have a maximum circumference of 29.5 inches, and they can weigh up to 1.38 pounds. This class is the biggest basketball size, and it’s used by major leagues like the NBA and NCAA. 

Size 6

The balls in this class can have a circumference of up to 28.5 inches and weigh up to 1.25 pounds. This class is used mainly by the WNBA and NCAAs women basketball. 

Size 5

Size 5 balls have a circumference of 27.5 inches, and they can weigh up to 1.06 pounds. This class is popular among youth basketball competitions. Size 5 balls are also convenient for kids between 9 and 11 years old.

Size 4

This ball has a circumference of 25.5 inches and weighs .9 pounds. It is suitable for kids between the ages of five and eight.

Size 3

This ball has a circumference of 22 inches and weighs .6 pounds. It is suitable for kids between the ages of four to eight. This class of ball is often called a mini basketball.

Size 1 

Size 1 balls have a circumference of 16 inches and weigh .5 pounds. They are the smallest size of balls, and they can be used by preschool kids between 2 to 4 years. 

Why Is the Weight of the Ball Important?

The way a basketball moves greatly depends on how much it weighs. There is a standard weight that all players must get used to before the main competition.

Once the players become familiar with the right weight, they can adjust the training ball to meet that exact specifications and get used to it before a game.

Also, keep in mind that a poorly inflated ball will not bounce as expected, and it is likely to change trajectory when launched.


The weight of a basketball is very important to the game since the weight affects how the ball will bounce, travel in the air, and how other players will handle it. 

To answer your question about basketball weight, the weight depends on who is producing the ball and its measurements!
