Round robin: give everyone a full set of opponents
In a single round robin, each entrant plays every other entrant once. For singles, an entrant is a player; for fixed doubles, it is a team. The total match count is n × (n − 1) ÷ 2. Eight entrants produce 28 matches, with seven matches per entrant. That makes round robin useful for a small social group, but demanding for a short session with many entrants.
Decide your match length and standings rules before play. If you split entrants into groups, calculate each group separately and allow time for the next stage.
Knockout: work toward a clear final
A single-elimination draw needs n − 1 completed matches to produce a winner, excluding a third-place match or other consolation play. Eight entrants need seven matches. Some entrants may receive byes when the field does not fill a bracket. Knockout is a practical choice when the final is the focus and court time is tight.
Double elimination gives entrants a route through a losers’ bracket after a first loss. It creates more opportunities to compete, but the final structure and possible reset affect the schedule. Check the actual generated draw before promising an end time.
Groups followed by knockouts: balance participation and a final
Group play gives entrants several opponents before the leading players or teams advance. For two groups of four, a single round robin creates 12 group matches. Advancing two entrants from each group adds two semifinals and one final: 15 matches in total, before any third-place match. Publish qualification and tiebreaking rules so players understand what they are playing for.
Open Ladder: keep the competition going between events
A ladder works when members arrange matches over time rather than completing a fixed draw in one day. Courtira’s Community Open Ladder uses Elo ratings. Members can submit their own results for opponent confirmation; undisputed results are accepted after 24 hours. Agree on how challenges, availability and disputes will be handled before inviting players.
Estimate court time before inviting players
Multiply the number of matches by your expected match duration, then divide by available courts for a rough capacity estimate. For example, 28 matches at 20 minutes on four courts require at least 140 minutes of court capacity. That is a lower bound, not a schedule: player rest, dependent rounds, warmups, overruns and court changes can extend the day.
Allow a buffer and choose scoring that suits your sport and group. A short social session and a full-set championship need different schedules.
