A seeded knockout, double elimination, or round-robin groups into a knockout, for singles or doubles. Matches are best of three games to 21 by default, and group tables rank on matches, then games, then points.
Scoring rules on this page are summarised from the documents above. The tool itself accepts any score, so house rules work too.
Best of three games, each to 21 points with rally scoring. At 20-all the game continues until one side leads by 2, and at 29-all the side that scores the 30th point wins the game. That is Law 7 of the BWF Laws of Badminton.
For a day event with 8 to 16 entries per category, round-robin groups of three or four feeding a knockout give everyone several matches. For a quick event, a single-elimination draw with a best-of-three-games format is fastest; double elimination guarantees two matches each.
Run each category as its own tournament. The tool keeps one event per page in your browser, so for several categories at once use the share link to save each one, or open the page in separate browsers or devices.
By matches won, then games won minus games lost, then points won minus points lost, then points won.
