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.
Comparison of Canadian football and rugby union
Although both codes are played on similar sized rectangular fields, the dimensions of rugby union fields can vary up to maximum size that is larger than the fixed size of Canadian football fields. Rugby union fields are limited to a maximum length of 144 m long (and 100 m between goal lines) and width of 70 m, while Canadian football fields have a fixed length of 150 yd (137 m) long and width of 160 ft (48.8 m). Both sets of measurements include scoring zones at each end. These are fixed to 20 yd and called the end zone in Canadian football, but of unspecified length in rugby union.
