Sidelines in the context of Pitch (sports)

A pitch or a sports ground is an outdoor playing area for various sports. The term pitch is most commonly used in British English, while the comparable term in Australian, American and Canadian English is playing field or sports field.

For most sports the official term is field of play, although this is not regularly used by those outside refereeing/umpiring circles. The field of play generally includes out-of-bounds areas that a player is likely to enter while playing a match, such as the area beyond the touchlines in association football and rugby or the sidelines in American and Canadian football, or the "foul territory" in baseball.

The end zone is the scoring area on the field, according to gridiron-based codes of football. It is the area between the end line and goal line bounded by the sidelines. There are two end zones, each being on the opposite side of the field. It is bordered on all sides by a white line indicating its beginning and end points, with orange, square pylons placed at each of the four corners as a visual aid (however, prior to around the early 1970s, flags were used instead to denote the end zone). Canadian rule books use the terms goal area and dead line instead of end zone and end line respectively, but the latter terms are the more common in colloquial Canadian English. Unlike sports like association football and ice hockey which require the ball/puck to pass completely over the goal line to count as a score, both Canadian and American football merely need any part of the ball to break the vertical plane of the outer edge of the goal line.

A similar concept exists in both rugby football codes, where it is known as the in-goal area. The difference between rugby and gridiron-based codes is that in rugby, the ball must be touched to the ground in the in-goal area to count as a try (the rugby equivalent of a touchdown), whereas in the gridiron-based games, simply possessing the ball in or over the end zone is sufficient to count as a touchdown.
