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.
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.
This is a youth basketball size used for girls and boys ages 9 – 11. Size 4: 25.5″ 14 oz: 7.5 to 8.5: 5-8 year old boys and girls. Size 3: 22″ 10 oz: 7.5 to 8.5: Mini basketball for boys and girls ages 4-8 years old. Size 1: 16″ 8 oz: 7.5 to 8.5: Micro Mini basketball for boys and girls ages 2-4 years old.
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 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.

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.
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.
For a 29.5″ basketball (mens) and a 28.5″ basketball (womens), the recommended air pressure range is 7 - 9 PSI. The irony is almost no one has a gauge to accurately check the PSI rating on a basketball while inflating it because most pumps aren’t equipped with a gauge and ones that are rarely give an accurate reading.
