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.
Tottenham Hotspur Stadium
The football pitch of the stadium has a standard dimension of 105m x 68m, this is equal to the pitches at Old Trafford and The Emirates stadium, which is 440 square metres larger than the pitch at White Hart Lane. The overall grass surface is 114.58m x 79.84m, including the perimeter between the pitch and the stands. The stands are placed close to the pitch so as to enhance the atmosphere on match days, and the distances between the stands and the pitch minimised – from the front of the stand to the pitch on the west, north and east sides of the pitch and at the south end of the pitch.
In order to keep the football pitch in optimum condition, there are two different surfaces – a Desso GrassMaster hybrid grass pitch for football, and a synthetic turf surface underneath to be used for NFL games, as well as concerts and other events. The football pitch can be retracted in a way similar to that of the Arizona Cardinals' home stadium, but it is the first in the world to split into three sections before retracting. Each of the three sections weighs more than 3,000 tonnes, and is made up of 33 smaller trays, making a total of 99 trays, with a combined weight of 10,000 tonnes. The retracting pitch slides under the South Stand and the south podium, and the surface can be switched in around 25 minutes. The NFL pitch is placed 1.5m beneath the natural turf surface, and the change in height when the surface is switched also produces ideal sightlines for the front row for both codes.
