They are 100 yards on a football field. They are also an addition 10 yards in each end zone. The ball is placed in the middle (middle of the hash marks) when ever it is either turned over or down in the end zone on a kick off.
Near each end of the field is a goal line; they are 100 yards apart. A scoring area called an end zone extends 10 yards beyond each goal line to each end line. Yard lines cross the field every 5 yards, and are numbered from each goal line to the 50-yard line, or midfield (similar to a typical rugby league field). Two rows of lines, known as hash marks parallel the side lines near the middle of the field.
