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.
Polo Fields
The Polo Fields is a large multi-purpose stadium and sporting field in San Francisco's Golden Gate Park. Despite its name, polo is rarely played on the Polo Fields. The facility has a multitude of uses. There are six regulation soccer fields surrounded by a .67-mile cycle track. Wooden bleachers overlook the field and track. Above the bleachers is a dirt track used for running and horse riding.
