The football field is 120 yards long and 53.5 yards wide. There is a labeled yard line every ten yards. On each end of the field there is an area called the end zone. If you run the ball into the end zone it is a touchdown. The team that scores the touchdown gets six points and a chance to get an extra point by kicking a field goal.
