In American Football, there are 100 yards on the field (120 including the 10 yard endzones), however they don't start in the middle of the field...(except for the coin toss).
High school, college and NFL football fields are the same size. A standard football field is 120 yards long. The playing field is 100 yards (300 feet) long, and each end zone is 10 yards (30 feet) deep. The field has a uniform width of 53 1/3 yards (160 feet). If you calculate the entire area of a football field, including the end zones, it works out to 57,600 square feet (360 x 160). One acre equals 43,560 square feet, so a football field is about 1.32 acres in size. The field is marked with a yard line every 5 yards, and every 10 yards is marked by a field number.
