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.
Calcio Fiorentino
Matches last 50 minutes and are played on a field covered in sand, twice as long as it is wide (approximately 80x40 meters). A white line divides the field into two identical squares, and a goal net runs the width of each end.
