About Matchup Generator
Turn a list of participants into pairings — either simple head-to-head matchups or a full tournament bracket. Seeding can follow the order you entered or be randomised.
Simple matchups versus a bracket
Simple matchups pair everyone once and stop: good for a single round, a discussion exercise or a one-off draw. A bracket carries winners forward, so it needs a participant count that halves cleanly — 4, 8, 16, 32. Any other number requires byes, where some entrants skip the first round.
Random seeding or as entered?
Seeding as entered assumes your order means something — strongest first, so the top seeds meet last. Random seeding removes that assumption and any suspicion of favouritism, at the cost of possibly pairing the two strongest entrants in round one.
How many rounds will a bracket take?
A single-elimination bracket of n players takes log₂(n) rounds: 8 players is 3 rounds, 16 is 4, 32 is 5. Total matches is always n − 1, because every match eliminates exactly one participant and all but the winner must be eliminated.
