American Football fields are rectangular playing  fields with a required length of 120 yards   (360′ | 109.75 m) and a width of 53.3 yards ( 160′ | 48.8 m). Based on yards, the field of   play in a game of football refers to the 100  yards  between the two opposing end zones  on either side of the field at 10 yards | (30′ | 9.15 m)  deep. White markings designate each individual  yard on the field and are separated by full field lines  every ten yards. The central hash marks are located 20 yards (60′ | 18.25 m) inwards from each team’s side line. Team areas are centered at the 50 yard line and extend 25 yards (75′ | 22.8 m) in both directions.
