Excellent Football 2011

Football is played on a field 360 by 160 feet (120.0 by 53.3 yards; 109.7 by 48.8 meters).The longer boundary lines are sidelines, while the shorter boundary lines are end lines. Sidelines and end lines are out of bounds. Near each end of the field is a goal line; they are 100 yards (91.4 m) apart. A scoring area called an extends 10 yards (9.1 m) beyond each goal line to each end line. The end zone includes the goal line but not the end line.While the playing field is effectively flat, it is common for a field to be built with a slight crown—with the middle of the field higher than the sides—to allow water to drain from the field.
