What size is an nba basketball? Size Of An NBA Basketball

What size is an nba basketball? Knowing what size basketball to use is important for any basketball player or coach. Using the correct basketball size ensures that games are played to competition rules and allows players to develop their ball skills and shooting technique which is essential for players of all ages.

Our comprehensive guide features a basketball size chart which clearly shows the correct basketball size by age. From kid’s size balls through to regulation NBA basketballs, we cover the recommended basketball sizes for players of all ages.

Our guide also covers the weights, circumferences, and recommended ball pressures for each basketball size, meaning you’ll find all the information you need to buy a basketball for you, your child, or someone else with confidence.

BASKETBALL SIZES BY AGE

It is essential that players of all ages use the correct size basketball. Not only will it ensure the competition rules are adhered to, but it will also allow key skills such as shooting, dribbling and receiving the ball to be developed. The older the player, the bigger size basketball they will use.

Using a basketball that is too big at an early age will lead to a less enjoyable experience, as the heavier ball will make the basketball harder to catch, more difficult to control when dribbling and more of a struggle to pass or shoot accurately.

Training with a ball that is too small for you can also cause issues. Whilst you might be able to master all the required skills with a smaller, lighter ball, when it comes to playing matches with the correct size ball, you may struggle to adjust to the bigger and heavier ball.

As you’d expect, the diameter of a basketball/circumference of a basketball gets bigger as the ball size increases. As the balls increase in size, the weight of a basketball also increases, with size 7 basketballs weighing more than twice as much as a size 3 basketball!

Youth basketball weights are lighter to allow players to develop skills and use a ball that is proportional to the size of the player. As mentioned previously, the size and weight of a basketball will have a great bearing on player performance, development, and enjoyment, so it is imperative to choose the right size basketball.

Basketball Inflation and Pressure Regulations

The inflation and air pressure of a basketball is also key to a game of basketball, as it not only affects ball performance but also has an impact on the weight of the basketball.

Using a ball that is over-inflated with an air pressure that is too high could result in the ball exceeding the ball weight and air pressure regulations. If a basketball has too little air inside, it will be too light and not fit within air pressure rules. This would impact the performance of the basketball, with the bounce off the ground and backboard being reduced.

The inflation of a basketball is easy to change. If your basketball needs more air pressure, simply use a pump and needle system by inserting the needle into the valve in the outer cover of the basketball and pumping air into the ball. If your basketball’s air pressure is too high and needs deflating, separate your needle from the pump and insert fully into the basketball. You should then hear the air coming out of the ball.

Once you are satisfied enough air has been removed, remove the needle, and check the weight and the air pressure of the ball to make sure it aligns with competition rules. To check the air pressure of your ball, use a ball pressure gauge reader by inserting the needle of the reader into the valve for an accurate reading in pounds per square inch.
