School and Training Plans

"Football games are played on a rectangular field that measures 120 yards (110 m) long and 53.33 yards (48.76 m) wide. Lines marked along the ends and sides of the field are known respectively as the end lines and side lines, and goal lines are marked 9 yards (8.2 m) outward from each end line. Weighted pylons are placed on the inside corner of the intersections of the goal lines and end lines.
White markings on the field identify the distance from the end zone. Inbound lines, or hash marks, are short parallel lines that mark off 1 yard (0.91 m) increments. Yard lines, which run the width of the field, are marked every 5 yards (4.6 m). A line one yard wide is placed at each end of the field. This line is marked at the center of the two-yard line in professional play and at the three-yard line in college play. Numerals that display the yard lines in multiples of ten are placed along both sides of the field.
Goalposts are at the center of the plane of each of the two end lines. The crossbar of these posts is ten feet (3 meters) above the ground, with vertical uprights at the end of the crossbar 18 feet 6 inches (6 m) apart for professional and collegiate play and 23 feet 4 inches (7 m) apart for high school play. The uprights extend vertically 10 yards on professional fields, a minimum of 10 yards on college fields, and a minimum of ten feet on high school fields. Goal posts are padded at the base, and orange ribbons are normally placed at the tip of each upright." [American football. Wikipedia]
