Modern football originated in Britain in the 19th century. Though “folk football ” had been played since medieval times with varying rules, the game began to be standardized when it was taken up as a winter game at public schools.
How did the football get its shape?
A football is a prolate spheroid, and it’s shaped that way because that’s also the shape of an inflated pig’s bladder, which is what the first footballs were made of. Soccer balls were also made of pig’s bladders, but as soon as technology permitted, those balls got rounder, which made them easier to kick.

How many psi is a football?
The NFL requires that all game footballs be inflated to a pressure between 12.5 and 13.5 pounds per square inch (psi), and that they weigh 14 to 15 ounces (397 to 425 grams), ESPN reported. The footballs in the playoff game were underinflated by 2 psi.
How hard should a football feel?
A football shouldn’t be squeezable, it should be taut and firm, but not hard. If you are using an older football, remember that leather hardens over time, so it may feel harder than a newer football. If your ball looks wobbly in flight, this can be a sign of a deflated ball, so check the psi.
