What is the accepted pressure range for footballs?
between 12.5 and 13.5 psi
The NFL’s rules require that a football be between 12.5 and 13.5 psi.
What are some factors that could affect air pressure in the footballs?
Changes in temperature, evaporating rain, and barometric pressure affect the pressure inside the football.
How do you tell if a football is properly inflated?
Proper Inflation and Feel Footballs used in the NFL are inflated to 13 psi, but a proper range can fall between 12.5 and 13.5 psi, according to Wilson Sporting Goods. A football shouldn’t be squeezable, it should be taut and firm, but not hard.
What PSI is the ball inflated to for testing?
between 8.5 psi and 15.6 psi
FIFA says the air pressure in a regulation soccer ball must be between 8.5 psi and 15.6 psi. You don’t want your soccer ball to be inflated to the wrong pressure for several reasons….SOCCER PRESSURE TABLE.
| BALL SIZE | PRESSURE |
|---|---|
| SIZE 4 | 8.5 – 15.6 PSI |
| SIZE 5 | 8.5 – 15.6 PSI |
What PSI is a Premier League football?
The ball should be inflated to a pressure of 0.6 and 1.1 bars (8.7 and 16.0 psi) at sea level.
Why does a football deflate in cold weather?
The “P” is pressure. But it proves that, when it’s cold, the pressure inside a football drops. In this specific situation, it could be that some pressure was removed from the balls, and that the 51-degree temperature did the rest. Regardless, when the mercury drops, footballs naturally deflate, at least a little.
How does temperature affect air pressure in a ball?
This is because the gas molecules inside the ball expand as temperature increases. As the gas molecules expand, their energy increases and they bounce around faster inside the ball. That’s why higher pressure leads to a higher bounce of the ball. Likewise, a lower temperature will lead to a lower pressure.

Why does my football keep deflating?
The inner bladder and valve components of a ball leak air gradually over its lifespan and, improper aftercare such as playing on unsuitable surfaces; inflating the ball to the incorrect pressure and failing to deflate when storing also contribute to gradual air loss.
What was the PSI of the Patriots footballs?
The consultants concluded that the drop in the p.s.i. of the Patriots’ footballs — the average was 11.3 p.s.i. — could not be fully explained by the Ideal Gas Law; it was too steep. But the smaller drop in the p.s.i. of the Colts’ footballs could indeed be explained by the laws of physics.
How many Colts balls were deflated?
That’s quite the contrast from the way the NFL handled leaks during its Deflategate investigation. Three days after the AFC Championship, which is when the Colts accused the Patriots of using under-inflated balls, ESPN’s Chris Mortensen falsely reported 11 of 12 Patriots footballs were deflated by two pounds of air.
