NBA recommends that the air pressure in a basketball must be between 7.5 and 8.5psi. You can use this standard measurement as a guide to get the required air pressure for your basketball. A quick way to check if your ball has the proper air pressure is by taking this simple test.
There are various measurements used for air pressure. Among them are pounds per square inch, millimeters of mercury, atmospheres, and pascals. In the United States, we measure this force using psi, or pounds per square inch. Conventional wisdom is that a basketball needs 8 psi to be properly inflated. A car tire, just for a comparison, needs 40 psi.
The recommended air pressure for a basketball is 7.5 to 8.5 psi (pounds per square inch). That is also the NBA basketball air pressure recommendation. As you can see, there isn’t a fixed air pressure endorsement by the NBA, but you can use this recommendation as a guide to getting the right air pressure.
An NBA regulation ball is inflated to between 7.5 and 8.5 psi. By regulating a basketball’s air pressure, the NBA can ensure fair playing conditions.
A regulation basketball used in NBA play is inflated to an air pressure between 7.5 and 8.5 pounds of pressure per square inch. Many balls are inflated to the average pressure of 8 pounds. Regulating a basketball's air pressure ensures fair playing conditions throughout a league. A ball's internal air pressure determines the height of its bounce.
Air pressure is what allows the basketball to bounce high and is measured in different ways. Basketballs are measured in PSI or pounds per square inch. A basketball should be about 8 PSI. For comparisons sake, a football needs between 12.5 and 13.5 pounds PSI, whereas a tennis ball needs a pressure of 14 PSI. A car tire has a pressure of 40 PSI!
The amount of PSI needed is anywhere from 7 to 9 pounds of air pressure, most Men’s 29.5″ basketballs are usually 8 PSI. There is a reason for that, due to materials used in the basketball, over-inflating the ball will could cause issues such as losing air and possibly creating a small leak on the rubber air valve.
