Ultimate is a non-contact, self-refereed team sport played with a flying disc (or Frisbee™).

Two teams of seven players compete on a playing field about the same length as a football field, but narrower. At each end of the playing field there is an end zone. Each team defends one end zone. They score a goal if one of their players catches the disc in the opposite end zone.

Ultimate relies upon a Spirit of the Game that places the responsibility for fair play on every player. There are no referees; the players are solely responsible for following and enforcing the rules, even at World Championship. Competitive play is encouraged, but never at the expense of respect between players, adherence to the rules, and the basic joy of play.

Playing Surface Measurement:

The playing field is a rectangle area with dimensions as shown in the image.

The perimeter lines surround the playing field and consist of 2 sidelines along the length and 2 endlines along the width.

The perimeter lines are not part of the playing field.

The brick mark is the intersection of 2 crossed 1 metre lines in the central zone set 18 metres from each goal line, midway between the sidelines.

8 brightly-coloured , flexible objects (such as plastic cones) mark the corners of the central zone and the end zones
