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.
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.
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.
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 adult for assistance. 3 basketballs: 1 basketball at 8 psi, 1 basketball at 9 psi and 1 basketball at 6 psi (psi = pounds per square inch) 1 Air pump. 1 Pressure gauge. 1 “Yardstick” style tape measure. 2 Different surfaces: 1 wood surfac,; 1 concrete surface. Marker (mark each basketball with the correct psi)
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.
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.
The standard pressure recommended for a basketball is 7 – 9 PSI (48.26 – 62.05 kPa). Unless you have a pressure gauge, and many air pumps do (we’ll talk about that in the next section), then you will not know what the air pressure in your basketball is. Not to worry, there is a simple method that you can use to check the inflation of your ball. It won’t give you the PSI (or kPa), but it will be good enough to get you back out on the court.
