An AFL (Australian Football League) field is an oval-shaped grassed ground with dimensions that vary, but the standard size typically ranges between 135 to 185 metres in length and 110 to 155 metres in width. The exact size can differ from one stadium to another, but these are the official ranges for professional AFL matches. The field includes marked areas such as the goal square, centre square, and boundary lines, with the playing surface size adhering to these dimensions.
