Office pools and prediction contests around NCAA tournament time. The 64-slot bracket is huge but readable on A3 landscape, and exporting as PDF means everyone can fill it in on their tablet.

Generate once, share the PNG. Each participant fills in their predictions in their own image editor, then sends back. Compare manually or in a spreadsheet.
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.
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.
Standard single-elim is 64. For First Four, run 4 mini-brackets first and feed the winners in.
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.
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.
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.
