How this single elimination plan works
Use this tournament format generator to decide how a competition should run before you build the final schedule. Enter the number of teams, choose a format, and compare match count, rounds, byes, play time, and tournament days in one planning console.
The tool is built for organizers who need a fast answer: school tournaments, office events, esports cups, sports leagues, club nights, and local competitions. It favors practical planning over account setup, so the first result is available immediately.
Single elimination includes a readable SVG bracket preview with BYE slots for non-power-of-two team counts. Round robin, group stage, Swiss, and double elimination provide match-count logic and scheduling guidance for early planning.
With the current preset, the calculator returns 15 matches across 4 rounds. At 30 minutes per match and 8 matches per day, the event needs about 2 days of scheduled play.

Frequently Asked Questions
+What is the best format for a quick tournament?
Single elimination is usually the fastest. It needs exactly n minus 1 matches to produce one champion, so a 16-team event finishes in 15 matches.
+What format is best when every team should play more than once?
Round robin or group stage. Round robin has every team play every other team, which maximises play time but creates many matches. Group stage is a middle ground: teams play a small round robin in their group, then the best teams advance to a knockout.
+How do I estimate how many days my tournament will take?
Divide total matches by your planned matches per day. A 32-team single elimination event (31 matches) at 8 matches per day takes about 4 days. Use the Matches per Day field to try different schedules.
