Free bracket generator (single & double elimination)

Need a tournament bracket for your event? With this generator you create the bracket for free: choose single or double elimination, set the seeds and the system builds the bracket automatically. Winners advance on their own and you share the bracket with a link. Nothing to install.

What you can generate

From a classic single-life bracket to brackets with a losers’ run, all configurable:

Single elimination: the classic single-life bracket; whoever loses is out.
Double elimination: with a winners’ and a losers’ bracket, so one defeat does not knock you out.
Seeding: order the favourites to split the bracket fairly.
Two-legged ties: enable home-and-away matches in the rounds you want.

How to create a tournament bracket step by step

Create a free account. Sign up in under a minute; no card required.
Create a competition and choose knockout. Select single or double elimination.
Add the teams or players and set the seeds. The order defines the seeding of the bracket.
Generate the bracket automatically. The system builds the round of 16, quarter-finals, semi-finals and final.
Enter the results and share the bracket. Winners advance on their own and the bracket updates live.

Worked example: a 16-team bracket with late withdrawals

Picture a bracket with 16 teams: you need exactly 4 rounds —round of 16, quarter-finals, semi-finals and final— because 2 to the power of 4 is 16. If only 12 teams actually sign up, the system hands out 4 byes (automatic passes) in round one so the numbers round up to the next power of two; those byes normally go to the top seeds, so nobody who does play round one is punished twice. And if seeds 1 and 2 are placed correctly, they sit on opposite sides of the bracket, so they can only meet in the final, never earlier in the quarters or semis.

Practical tips for your bracket

Put seeds 1 and 2 on opposite sides: so the two favourites can only meet in the final, never before.
Hand out byes with a criterion: if the number of entrants is not a power of two, give the round-one byes to the top seeds, not at random.
Agree the two-legged tiebreaker in advance: away goals, extra time or penalties —settling it after the result is known causes arguments.
Warn everyone about the grand final: in double elimination, the undefeated finalist may need to win the final twice, so nobody is caught by surprise.

Common mistakes

Drawing without seeds: in a competitive event, a fully random draw can knock out the two best entrants against each other in round one purely by bad luck.
Getting the byes wrong: if entrants are not a power of two and byes are not assigned, the bracket ends up unbalanced and some rounds make no sense.
Forgetting the grand final: crowning the winner of the first final without checking whether the undefeated finalist actually lost it, which forces a second match.
Changing format mid-tournament: switching from single to double elimination (or back) once the bracket is underway scrambles what has already been generated and confuses everyone.

Bracket, league or Swiss: which to choose

A knockout bracket is the fastest way to produce a single champion from a large group: with 16 entrants you only need 4 rounds (log2 of 16), against the 15 matchdays a double round-robin league would take, or the repeated pairings a Swiss system needs to settle a clear winner. In exchange, it is the toughest format: one bad day puts you out even if you were the best player in the tournament, something a league or Swiss system smooths out over more rounds. If you want speed and an unquestionable winner in little time, use a bracket; if you would rather let results even out over more matches, check our league or Swiss-system guides.

Frequently asked questions

Is the bracket generator free?

Yes. You can create and share your tournament bracket for free, with single or double elimination, seeding and live standings.

What is the difference between single and double elimination?

In single elimination you lose one match and you are out: it is the shortest format and the one with the most pressure on every match. In double elimination, your first loss sends you to the losers’ bracket; if you win it, you face the undefeated finalist from the winners’ bracket, and if you beat them a second final is needed (the bracket “reset”) because they had not lost a match yet.

How does seeding work in the bracket?

Seeding is the ranking you give entrants before the draw, based on their level. The system uses it to keep favourites apart in the early rounds, so the bracket stays balanced right up to the closing rounds.

How do I stop the two favourites meeting before the final?

By placing seed 1 and seed 2 on the two opposite ends of the bracket. As long as both keep winning, they can only meet in the final, never earlier in the quarters or semis.

What happens if the number of entrants is not a power of two (8, 16, 32)?

The system hands out byes (automatic passes): some entrants skip round one and go straight to round two, so the number of matches lines up with the next power of two. For example, 12 entrants generate 4 byes to reach 16.

How many rounds do I need for a 16- or 32-entrant bracket?

It depends on the size: 8 entrants need 3 rounds, 16 need 4, and 32 need 5 —the number of rounds is always the base-2 logarithm of the total number of entrants.

What is the “grand final” in double elimination?

It is the second final match, only played if the finalist who came in undefeated from the winners’ bracket loses the first final against whoever came through the losers’ bracket. Because that finalist had one life to spare, they must be beaten twice to be dethroned, hence the scoreboard reset.

Can matches be played home and away?

Yes. You can enable two-legged ties in whichever rounds you choose, useful above all in the quarter-finals, semi-finals or final, where a single match can hinge too much on luck.
