Don’t bother if you didn’t see it on your ball—not every manufacturer prints it on their basketballs. 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.
Maddie Meyer/Getty Images Sport/Getty Images. A regulation NBA basketball must contain between 7 1/2 and 8 1/2 pounds of pressure per square inch, or PSI. The ball also must exhibit an official NBA approval mark. At the beginning of an NBA game, each team must have access to six balls during the warm-up period.

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. Using Newton's laws of motion as an explanation, the ball's internal pressure applies force to any surface it hits, causing an equal force to repel ...
