12 team bracket

Twelve entrants make 4 rounds and 11 matches in a 16-slot draw, with four byes. Type your names over the sample ones and print.

What a 12-team draw looks like

12 entrants need a 16-slot bracket, because a knockout draw halves the field each round and only a power of two halves cleanly all the way down. That gives 4 rounds: round of 16, quarter-finals, semi-finals and final.

Four slots are empty, so four of the 12 entrants skip round one and join at the quarter-finals. They go to the top four seeds, because a bye is one fewer match to win and that advantage belongs to whoever earned the seeding.

The match count is fixed at 11 whatever the byes do, because every match eliminates exactly one entrant and all but the winner must be eliminated. That identity is the quickest way to check any bracket, printed or drawn: count the boxes, and if it is not 11 something is wrong with it.

Running a 12-entrant tournament

Eleven matches is a long evening on one court and a comfortable afternoon on two. The first round is 8 matches on its own, so it is worth having somewhere for people to be while they wait.

Seeding 12 entrants means seed 1 meets a bye first and cannot meet seed 2 before the final. The slot order for 16 slots runs 1, 16, 8, 9, 4, 13, 5, 12, and so on, generated from the size rather than copied from a table — which is what makes it right here and not only for sixteen.

If nobody has a ranking, draw it at random instead. A guessed seeding is worse than none: it puts an error into the draw systematically, and with 12 entrants that error decides the tournament more often than the guess was ever worth.

Printing a 12-team sheet

16 slots — 12 entrants and 4 byes — fits one A4 sheet in landscape at a size somebody can write in.

The print stylesheet removes the header, the navigation, the advertisement and the URL, so 8 first-round boxes and everything after them are all that reaches the paper. Names print into the boxes if you have supplied them and come out empty if you have not, which is how one page gives you both a filled 12-entrant draw and a blank sheet to fill in at the table.

Print a spare. A 12-entrant draw takes one name written in the wrong box to become a sheet somebody has to redo, and it happens at most draws.
