How many pounds of air should a soccer ball #5 have?

A soccer ball #5 should be inflated with 8 to 10 psi of air. This is the standard recommended by most sport organizations, including FIFA. To calculate the amount of air needed, multiply the pressure in pounds per square inch (psi) by the surface area of the ball. A #5 soccer ball has a surface area of 2750 square inches, so 8 to 10 psi of air would be 22 to 27.5 pounds of air. To maintain the ball's performance and shape, it is important to check the inflation level at least once a month.
