How to make a tournament bracket
A tournament bracket turns a list of teams into a clear path to a single champion. Here is how to build one properly — the same steps Roundra automates for you.
1. Collect your participants
Start with a clean list of teams or players, one name each. Remove duplicates and blanks so every slot is meaningful. The number of participants decides the shape of the bracket: a field of 4, 8, 16, or 32 fills a knockout perfectly, while other counts need byes (explained below).
2. Choose a format
The format decides how a loss affects a team. The three most common are:
- Single elimination — one loss and you're out. Fast and easy to follow.
- Double elimination — a losers bracket gives each team a second chance.
- Round robin — everyone plays everyone; a standings table decides the winner.
Not sure which to pick? Read single vs double elimination or the round robin scheduler guide.
3. Seed the field
Seeding sets who meets whom. Standard bracket seeding pairs the top seed against the lowest seed, the second seed against the second-lowest, and so on, so the strongest teams only meet in later rounds. If you don't have rankings, a random shuffle produces a fair, unbiased draw.
4. Handle byes
When the number of teams isn't a power of two (2, 4, 8, 16…), the bracket rounds up to the next power of two and the empty slots become byes. A team drawn against a bye advances automatically to the next round. Good seeding awards byes to the top seeds so the draw stays fair.
5. Advance winners to the champion
As each match finishes, record the winner. That team moves into the next round, its slot filling the match above it, until the final crowns a champion. If you enter scores, the winner is the higher score; you can add an optional third-place match in elimination formats.
Build it in seconds
You can draw all of this by hand, or paste your list into Roundra and let it do the seeding, byes, and advancement automatically.
