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 backboard measures 6 feet wide and 3 1/2 feet tall.
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.
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.
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. Most basketballs have inflation instructions printed right on them.
An NBA basketball must be inflated to a pressure of 7.5 to 8.5 PSI. The WNBA uses the same pressure regulations.
The recommended air pressure in a basketball is between 7 and 9 pounds per square inch (psi). When dropped from a height of 6 feet, a properly inflated basketball should bounce upward between 52 and 56 inches (http://www.bestsoccerbuys.com/balls-basketball. html). The basketball coach at a local high school purchased 10 new basketballs for the upcoming season, inflated the balls to pressures between 7 and 9 psi, and performed the bounce test mentioned above.
Basketball What is the recommended inflation level for a basketball? 7 to 9 PSI (pounds per square inch) What does PSI mean? PSI means Pounds per Square Inch. Why should I not inflate a ball over the intended PSI? Over-inflation may damage the integrity of the ball and it will not perform to standards.
