Round robin: more opponents, more matches
Eight entrants in a single round robin produce 28 matches, seven per entrant. Four courts can host four matches at once, so a numbered round-based plan needs seven waves. With assumed 20-minute matches and five-minute gaps, that is a 170-minute playing window before check-in, warmups or long breaks. In fixed doubles, the eight entrants are teams, not individual players.
Single elimination: fewer matches, an earlier exit for some
Eight entrants need seven matches to decide a champion: four quarterfinals, two semifinals and a final. Even with four courts, those stages run in sequence. At an assumed 45 minutes a match with ten-minute gaps between stages, a no-overrun example needs 155 minutes. This is not a recommended rest policy: choose appropriate recovery time for your sport and players. First-round losers have played only once.
Groups followed by knockouts: a middle ground
Two groups of four create 12 group matches. Advancing two entrants from each group to semifinals adds three knockout matches, giving 15 total. Each entrant gets three group matches; finalists play five matches in all. A third-place match adds one more. Publish group qualification and tiebreaking rules before the first result.
Court capacity is not the same as an executable schedule
Total match-minutes divided by courts gives a capacity minimum. It ignores round dependencies and player rest. A final cannot start before its semifinal winners are known, and a player cannot be on two courts at once. Compare both the total capacity and the actual order of matches, especially when later rounds use fewer courts.
Build a plan for delays
Keep a realistic finish buffer, decide what to do if courts become unavailable and tell players where official schedule updates appear. Do not quietly change qualification or scoring after people have started. If you need to change the event plan, explain the change clearly and make sure participants understand it.
Use the format that fits your purpose
Choose round robin when several opponents for everyone matter most. Choose knockout when a clear championship path matters and entrants accept an early exit. Choose groups into knockouts when you want participation plus a final. Double elimination and Compass Draw offer other experiences, but inspect their actual generated draws rather than applying single-elimination time estimates.
