How to Inflate a Basketball – With a Pump and Air Compressor

Last Updated May 13, 2024 Last Updated February 28, 2024 by Brian Aquino

A basketball needs to be inflated at recommended air pressure for it to perform at its best. If you are wondering how to inflate a basketball, here we’ll explain easy ways to pump up the ball. Inflate the basketball at recommended PSI (pound-force per square inch), it will have consistent bounce while dribbling and precise flight to the hoop while shooting the goal.

As we know new basketballs come inflated and the best basketballs will retain the PSI for a long time. However, it loses some pressure after playing a couple of games – resulting in inconsistent bounce and poor performance. Weather also plays a role in the air pressure: the pressure drops if you are playing in either too cold or too hot weather on outdoor courts. Also, the basketball gets deflated if you don’t play with it for too long. So, if your ball is flattened by any of the above causes, we’ll guide you through the process of how you can inflate a basketball at home following easy steps.

How to Inflate a Basketball Properly – Right Ways

It is important to inflate a basketball properly and in the right way for feel, bounce, and durability. An under-inflated basketball will not bounce well while dribbling, bank shots will fall back and the ball will not travel the expected distance in long bounce passes.

On the other hand, an over-inflated basketball will bounce too high, bank shots will be too hard and off the rim. Plus, the bounce passes will travel a longer distance than expected – resulting in weak performance. Therefore, it is essential to follow the recommended PSI advised by the basketball company while inflating the ball.

How to Find out If the Basketball is Properly Inflated?

properly inflated basketballAs we mentioned above, an over-inflated or under-inflated basketball will not perform well.

The NBA official basketballs are inflated between 7.5 to 8.5 PSI. Most of the official size or close basketballs have recommended PSI from 7 to 9. Simply attach the gauge nozzle with the valve to monitor the air pressure.

Do not worry if you don’t have an inflation gauge. There is another ancient way of finding if the basketball is inflated properly – follow the below steps;

  1. Hold the basketball still at your face level at 90ᵒ
  2. Release it without any force and let it drop down straight

  4. A properly inflated ball will bounce back up to your waist, over or under-inflated will bounce either higher or lower
