Size one and two footballs are not typical to most fields. They are the categories reserved mostly for promotional footballs and their size and weights will vary depending on the company that created them.

Size four footballs are used with players between eight and twelve years old. They are slightly bigger than size three footballs, with circumferences between 25-26 inches and tend to be slightly heavier, 12-13 ounces, when compared to other footballs.
