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).
A football field is marked with yard lines every 5 yards starting at either end zone line. If a player crosses either of the sidelines with the ball, he is considered to be out of bounds and the next play begins where the ball went out of bounds.
