Round Robin Calculator

n(n−1)/2 for a single round. Eight teams play 28 matches; sixteen teams play 120, because the count grows with the square of the field.

One fewer than the number of teams if that number is even, and the same as the number of teams if it is odd — because one team sits out each round.

One team receives a bye each round, so the schedule takes as many rounds as an even field one larger. Rotating the bye fairly is part of a good schedule.

Every pair meets twice, usually home and away. It doubles both the matches and the rounds, and it is what most football leagues use.

The circle method: fix one team and rotate the rest around it. It guarantees every pairing exactly once and it is easy to do by hand.

When every entrant should get a comparable number of matches and the strongest overall should win. A knockout is far shorter and considerably more vulnerable to a single upset.

A scheduling technique: fix one team and rotate the others around it, pairing across the circle. It guarantees every pairing exactly once and can be done on paper.

Commonly by head-to-head result, then goal difference or points difference, then goals scored. The tiebreakers should be published before the competition rather than decided when needed.

Pairing entrants with similar records each round rather than playing everyone. It identifies a winner in far fewer rounds than a round robin and is standard in chess.

Either void all their results or award walkovers, and the choice affects the final table materially. Deciding the policy in advance avoids an argument at the worst moment.

Yes, and frequently does with an even number of teams. That is why tiebreak criteria matter and why some formats add a playoff.

Matches times duration divided by concurrent capacity, which this calculates. Capacity is usually the binding constraint rather than the number of matches.
