What Tournament Bracket Generator Does
This bracket generator builds a single-elimination tournament bracket for 2 to 64 teams or players in one click. Enter the entrants in seed order and it places them in the standard seeding pattern — 1 against the lowest seed, 2 in the opposite half — so the strongest entrants can only meet late in the tournament. When the number of entrants is not a power of two, the top seeds receive first-round byes.
Click the winner of each match to move them forward; the rounds fill in through to the champion. Changing an earlier result automatically clears any later picks that depended on it. When you are done, download the bracket as a PNG image to print, post in a group chat or put on a screen. Nothing is stored online and no account is needed.
For casual events with no ranking, Random draw shuffles the entrants with your browser’s cryptographically secure random generator before seeding.

Formula Used by Tournament Bracket Generator
Bracket size and byes
Slots = next power of 2 ≥ entrants · byes = slots − entrants · rounds = log₂(slots)
Worked example
10 teams.
- Next power of two: 16
- Byes: 16 − 10 = 6, to seeds 1–6
- Rounds: log₂16 = 4
Result: Four rounds; 9 matches are played in total (always one fewer than the number of entrants).
Standard First-Round Pairings

| 16 | 1–16, 8–9, 4–13, 5–12, 2–15, 7–10, 3–14, 6–11 |
How to Read Your Result
Why seeding matters
Without seeding, the two best entrants could meet in the first round and one of them would be out early, making the final less competitive. Standard seeding rewards the higher seeds with the easiest path, and in a perfectly predictable tournament the top seeds would reach the semifinals.
How many games to schedule
A single-elimination bracket always has exactly one fewer match than entrants, because every match eliminates one entrant and all but the champion must be eliminated. Plan time slots and courts from that number.
