Just how wide is a football field? The NFL, NCAA and high schools have similar standards for width with some very slight differences for other dimensions. Canadian football has its own set of standards. Here, you'll get the full scoop on the dimensions of both American and Canadian playing fields.
The outside width of an NFL American football field is 53-1/3 yards. This width is the equivalent of 160 feet. The length of an American football field is 120 yards or 360 feet. The length figure includes the endzones which are ten yards each. Most people do not include the endzones when referring to length. In this case, you can say that a football field is 100 yards long.
Notice that you never see NFL football teams competing with Canadian CFL teams. One reason for this is that the football fields have different dimensions. A Canadian football field is a little wider than its US counterpart. Their football fields are a 65 yards wide. The length of the Canadian field is 150 yards and the end zones are twenty yards each. Without the endzones, the length is effectively 110 yards.
American high schools have slightly different football field dimensions than the NFL. The goal posts of a high school field in the USA are ten feet high. The width of the posts amount to 23 feet and four inches. NCAA and NFL are still ten feet high, but they shorten the width to 18.5 feet.
In case you're wondering about "football" in the World Cup sense: A "soccer" field, as it's called in the United States, is 64 to 75 meters wide and 100 to 110 meters long according to FIFA standards for international games. Games that are not international can be played on a field that is 45 to 90 meters wide and 90 to 120 meters long.
