How long is a football field?

An American football field is 100 yards from goal line to goal line, with a 10-yard end zone at each end, making the full length 120 yards, or 360 feet. The width is 53 and one third yards, which is 160 feet, an odd-sounding number that comes from the sport's early standardization when field dimensions were fixed in feet. Goalposts stand at the back of each end zone in the NFL and college, with the crossbar 10 feet high and uprights 18 feet 6 inches apart in the pros, slightly wider in high school.

Some useful comparisons since this question usually arises from converting mental units. A football field including end zones is just under seven percent of a mile, so about 14.7 fields laid end to end make a mile. A soccer pitch is larger and, unusually among major sports, variable, with international matches typically around 115 by 74 yards, since the laws specify ranges rather than fixed dimensions. Canadian football uses a notably bigger field at 110 yards of play plus 20-yard end zones and greater width, which is why the Canadian game features more open-field space and three downs instead of four. The hash marks, where the ball is spotted after plays ending near the sideline, are much closer together in the NFL than in college, which meaningfully changes offensive geometry between the two levels.
