Early soccer balls were organically shaped pig or cow bladders bundled in leather. The iconic soccer ball pattern emerged over time. American football evolved from rugby into its familiar oblong shape by the late 1800s to allow throwing.

The Similarities between Football (American Football) and Soccer are: Both games allow substitutions, although the numbers are different. Both the sports have goal posts, although they are of different dimensions. Both the sports have rectangular shaped fields, but the length and width varies.

Regulation soccer balls have a circumference of 27-28 inches. American footballs are longer at 11 inches and bigger around at 28 inches end to end. Football’s larger size aids grip and throwing. Soccer’s smaller dimension allows better ball control with the feet. My brother and I had fun comparing ball sizes across different sports growing up.
