Tennis polo
The sport is played on a grass field between 80 and 100 yards long and 50 to 65 yards wide. The goal area is a semicircular line with an 11-yard radius and the penalty mark at 13 yards from the goal. An experimental rule has a second semicircular line on the field with a 17-yard radius. Generally, a field for gridiron football or soccer can be used.
Soccer-specific stadium
In the 1980s and 1990s, first-division professional soccer leagues in the United States, such as the North American Soccer League and Major League Soccer, primarily used American football fields, many of which were oversized in terms of seating capacity and undersized in terms of width of the soccer field; they often used artificial turf (none of which, at the time, were approved for international soccer under FIFA rules). Although many of the baseball parks had smaller capacities, natural grass, and a wider field, these parks were generally in use during summer, when North American–based soccer leagues, such as Major League Soccer, also hold their seasons, and the irregular field dimensions and sightlines were often considered undesirable.
