The international association of soccer, FIFA, lays out the required soccer field dimensions for all international matches, including the World Cup, the European Championships, the Olympics and any qualifying games. For FIFA to recognize any international match, it must be played on a field the dimensions of which fall into the range laid out in FIFA's Laws of the Game handbook.
Field Dimensions
The touchline of an Olympic soccer field must be 100 meters -- 110 yards -- to 110 meters -- 120 yards -- long and the goal line must be 64 meters, about 70 yards, to 75 meters, about 80 yards, wide. These dimensions apply to both men and women's games. Wembley Stadium, where the men's and women's soccer finals were held during the 2012 Summer Olympics in London, is 105 meters by 68 meters.
