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.
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. This basketball size chart gives you the size, radius, weight, and PSI (pressure per square inch) and a reference for what age group it should be used for.
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.
or simply “psi.” Your basketball will likely direct you to inflate the ball somewhere between 7 to 9 pounds per square inch.
An NBA basketball must be inflated to a pressure of 7.5 to 8.5 PSI. The WNBA uses the same pressure regulations.
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 ...
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.
