About SportsBracket

Bracket planning for organizers who need the numbers before the draw.

SportsBracket is built for tournament organisers who need to understand a competition before they commit to a format. Start with the estimator to get accurate match counts, then build and share the bracket, export a PDF, and manage your event checklist — all in one place.

What you can use today

  • Estimate match count, round count and byes for any sport, format and participant count.

  • Bracket creation with up to 16 participants free, unlimited on Pro — with live shareable bracket links.
  • PDF export for print-ready bracket sheets suitable for weigh-in tables, walls and officials.

What we are building toward

  • More verified sports and national rulesets, with source links and organiser overrides.
  • Club management — multiple organisers under one account with shared brackets and checklists.
  • Additional bracket formats: full repechage (IJF 2.5.4), Swiss, and custom pool structures.
  • Scoreboard and live display tools for mats, screens and event day staff.
  • Club branding on exported PDFs and shared bracket pages.

Why start with the calculator?

The hard part of tournament software is not drawing boxes. It is knowing which boxes should exist for the chosen sport, ruleset and number of participants.

A small category might need pools. A senior judo category might use quarter-final repechage. A custom event might need organiser-defined rules. The estimator makes those choices visible before you commit.

Once the math is trustworthy, full bracket creation, PDFs and live display can be built on top of the same model — instead of guessed by hand at every event.

Built from real event experience

SportsBracket is developed in Sweden by people who organise combat sports competitions — including national judo events, Europacups, and club championships across multiple age groups and weight categories.

The planning guides on this site are written from that experience: real repechage formats, actual SJF weight categories per age group, mat planning with referee constraints and rest periods, arena presentation, and the difference between IJF competition systems at different athlete counts.

The content is reviewed against IJF Sport and Organisation Rules and corrected when rules change. If you find an error, contact us — we fix it.
