Bracket sizing and byes
Single-elimination brackets only exist in power-of-two sizes: 2, 4, 8, 16, 32, 64. When your team count falls between two of those, the bracket maker rounds up and inserts byes for the highest seeds. So 11 teams becomes a 16-slot bracket with five byes, all assigned to the top five seeds. That preserves the 'top seeds shouldn't meet until late' principle and gives lower seeds a real path through the play-in round. If you'd rather have everyone play round one, pad the field with practice slots or switch to a round-robin format on a separate page.
Printing for the wall
The bracket renders as plain SVG, which is why it stays sharp on any paper size — A4, A3, US Letter, US Tabloid. For a wall-sized print, export as PDF and send it to a copy shop with 'fit to page' on A2 or A1; the lines and labels remain crisp because there's no rasterisation in the pipeline. For digital sharing, PNG export rasterises at 2× the on-screen resolution which is plenty for Slack, Discord, or email. Match colours to your event by tweaking team names with emojis (🟦 🟥 🟩) — they print fine and scan well from across a room.
FAQ
Frequently asked questions
What about absolute?
Run an extra bracket with the top 8 from across weights. Generate, print, run after the divisions.
Can I edit team names after generating the bracket?
Yes. Click any team slot in the bracket and the name becomes editable. Edits stick across re-renders within the same session. If you reseed the bracket the edits are preserved as long as the team count doesn't change.
Does the bracket support double-elimination or losers' bracket?
Not yet. The current bracket maker is single-elimination only. For most amateur and one-day tournaments single-elim is the right format because it keeps the schedule predictable. Double-elim is on the roadmap; if it would help you, send a note via the contact page so we know to prioritise it.
How do I score matches?
Click a team in any matchup to mark them as the winner — they advance automatically to the next round. Click again to undo. The bracket doesn't track scores numerically; it just tracks who advanced, which is the only state the bracket itself needs.
