American Football, simply football in the United States and Canada, is a team sport where two teams of eleven players advance an oval-shaped football down a rectangular field to score points. The football is moved by the team on offense through designed running or passing plays, while the defense attempts to stop their momentum. The offense must successfully gain ten yards in four plays or the ball is turned over to the defending team. Points are scored when one team moves the ball into the opposing team’s end zone, resulting in a touchdown (six points), by kicking the ball through the field goal post (three points, one extra point after a touchdown), or by tackling the offense inside their own end zone resulting in a safety (two points). The NFL (National Football League) is the professional league in the United States.
American football field goal posts are centered above the outside edge of both end zones on a football field. Comprised of a crossbar and vertical uprights, professional field goal posts reach a height of 35’ | 10.7 m and are capped with orange flags to visualize the direction and strength of the wind. A field goal’s crossbar is placed at 10’ | 3.05 m above the playing surface and the vertical uprights are split by 18.5’ | 5.64 m on professional and college fields (23’4” | 7.11 m for High School). Padding should always be placed on the field goal base for player safety.

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. American football fields are made of either natural grass or artificial turf.
