The playing field is 100 yards long.
It has stripes running across the field at five-yard intervals.
There are shorter lines, called hash marks, marking each one-yard interval. (not shown)
On each end of the playing field is an end zone (red section with diagonal lines) which extends ten yards.
The total field is 120 yards long and 160 feet wide.
Located on the very back line of each end zone is a goal post.
The spot where the end zone meets the playing field is called the goal line.
The yardage from the goal line is marked at ten-yard intervals, up to the 50-yard line, which is in the center of the field. After reaching the 50-yard line, the yardage markers start to descend (40, 30, 20, 10) every ten yards until they reach the opposite goal line.
