In American Football, there are 100 yards on the field (120 including the 10 yard endzones), however they don't start in the middle of the field...(except for the coin toss).
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.
