Major League Soccer ( MLS ) -- Current MLS soccer-specific stadiums

Soccer-specific stadium is a term used mainly in the United States and Canada to refer to a sports stadium either purpose-built or fundamentally redesigned for soccer and whose primary function is to host soccer matches, as opposed to a multi-purpose stadium which is for a variety of sports. A soccer-specific stadium may host other sporting events (such as lacrosse, American football and rugby) and concerts, but the design and purpose of a soccer-specific stadium is primarily for soccer. Some facilities (for example Toyota Park, Toyota Stadium and Mapfre Stadium) have a permanent stage at one end of the stadium used for staging concerts. A soccer-specific stadium typically has amenities, dimensions and scale suitable for soccer in North America, including a scoreboard, video screen, luxury suites and possibly a roof. The field dimensions are within the range found optimal by FIFA: 110-120 yards (100-110 m) long by 70-80 yards (64-73 m) wide. These soccer field dimensions are wider than the regulation American football field width of 53 1⁄3 yards (48.8 m), or the 65-yard (59 m) width of a Canadian football field. The playing surface typically consists of grass as opposed to artificial turf, as the latter is generally disfavored for soccer matches since players are more susceptible to injuries. However, some soccer specific stadiums, such as Portland's Providence Park and Creighton University's Morrison Stadium, do have artificial turf. The seating capacity is generally between 18,000 and 30,000 for a Major League Soccer franchise, or smaller for college or minor league soccer teams. This is in comparison to the much larger American football stadiums that mostly range between 60,000 and 80,000 in which the original North American Soccer League teams played and most MLS teams occupied during the league's inception. As opposed to gridiron-style football stadiums, where the front row of seats is elevated several feet above the field of play to allow spectators to see over the heads of substitute players and coaches on the sidelines, soccer-specific venues typically have the front row closer to the level of the pitch.
