Football is one of the most popular sports in the world; it is played on a field that can be called by several different names depending on the region. In the United States, the term "football field" is commonly used, but other synonyms for the same thing include "pitch," "gridiron," and "playing surface." In Europe, "pitch" is the most commonly used term, while in Australia and New Zealand, it is known as the "oval." In South Africa, the term "field of play" is used. Whatever the name, the dimensions of the field are generally the same for all varieties of football, and the field is typically divided into two halves, with various markings indicating the location of the goalposts and the center line.
