Choosing the right tournament format: groups, knockout or mixed

The format determines the number of matches, how long the day lasts and the experience of the participants. A poor choice can knock out half the teams after a single match, or, on the contrary, stretch the event into the evening.

There are three main families: group stages, knockout and the mixed format that combines the two. The right choice depends above all on the number of teams and the time you have.

Every losing team leaves the tournament. It is the shortest format and the easiest to understand, ideal when time is very limited.

Its drawback: a team might travel hundreds of kilometres to play just ten minutes. For a friendly tournament, that is often frustrating. Keep it for the final phases or events that are very tight on time.

Each team faces all the others in its group. It is the fairest format: a bad start does not ruin the whole day.

In return, it generates a lot of matches. With many teams, plan several groups running in parallel and enough courts to keep up the pace.

You start with group stages to guarantee everyone several matches, then the top-ranked teams play a knockout phase. It is the most widely used format for one-day tournaments.

It strikes a good balance between fairness and suspense: the final phase raises the stakes without penalising those who start badly.

Start from the number of teams and the total time available. Divide the time by the length of a match and the number of courts to estimate how many games fit into the day.

If the maths gets complicated, a tool like Cancha simulates the schedule based on the chosen format and shows you straight away whether the day fits the time slots. You make adjustments before the event, not during it.
