An official NFL football is slightly larger than high school or other professional leagues. The length should measure about 11 inches from tip to tip, and the in circumference at the center of the football should measure about 22 inches.imilar to other levels of football, the NFL uses an egg-shaped football, but the NFL has specific rules to the size, shape and materials used for the football. The Digest of Rules of the NFL explains the official size requirements for the football, along with other basic rules for playing the game.
Next, how long is a football field? According to the NFL rule book, a field is 360 feet, or 120 yards, long. (By the way, did you know that NASAâs International Space Station is about the size of a football field?o letâs do some math. A person driving at 55 m.p.h. would cover 80.7 feet per second. Multiply that by 5 and the person would drive 403 feet over 5 seconds -- or more than the 300 feet or 360 feet length of a football field.
