Arena Football League and Other Leagues
The average American football field is 360 feet long and 160 feet wide. The field is delineated by yards, which makes it 120 yards from the back of one end zone to the back of the other, and about 53.3 yards wide. Field goal posts are placed in the middle back of each end zone, with a crossbar that sits 10 feet off the ground with vertical uprights that are 18 feet 6 inches wide. These dimensions are consistent through most ranks of football.
Offensive and Defensive Zones
The football field is split into offensive and defensive zones that are each 50 yards long. The defensive zone starts at midfield, which is the 50-yard line, and stretches back to the end zone that the defensive team is protecting. The offensive zone begins at the 50-yard line and extends to the goal line at the end zone that the opposing team is protecting. For example, when a team has the ball on its side of the field at the 40-yard line, it is said to be on its own 40-yard line.
Hash Marks
After each play, the ball is placed at the spot of the ball where the ball carrier's body hit the ground and was considered down by contact. If the ball is outside of the hash marks, the ball is replaced inside the hash marks before the next snap. The hash marks are a series of two lines marking each yard of the field from end zone to end zone. In the NFL, the set of hash marks is 70 feet 9 inches from the sideline, creating an area that is 18 feet 6 inches wide, in which the ball always is placed before each snap to prevent the play from starting too close to the sideline. In college football, the hash marks are set farther apart, meaning that the short side of the field, which is considered the area closer to the sideline from where the ball is snapped, is much closer to the sideline than in the NFL.
Canadian Football League
The Canadian Football League (CFL) has many rules that are much different from the NFL, starting with the fact that its field is 20 yards longer than the NFL. While the dimensions of the offensive and defensive zone are the same as in the NFL, each end zone is 60 feet deep in comparison to 30 feet deep in the NFL. This makes passing plays much more viable as they get closer to the end zone in the CFL because of the additional room for the receivers to run.
Arena Football League and Other Leagues
The Arena Football League is an indoor league that features numerous former college and NFL players. The field is about half the size of the NFL field, with the 25-yard line acting like the 50-yard line in the AFL. The length of the field usually is around 200 feet long, depending on the dimensions in the arena. In addition, smaller high schools that play seven- or eight-man football Adidas F50 adizero TRX FG [http://www.hotsoccercleats.com/adidas-soccer-cleats/adidas-f50-adizero-trx-fg.html] might play on fields that are smaller than regulation size.
