One loss
Grand final, and the reset
Top box: the entrant who arrives undefeated. Bottom box: the one who arrives out of the losers bracket, already carrying a loss. The second match is played only if the undefeated entrant loses the first — at that point they have lost once, and one loss does not eliminate anybody in this tournament.
What 11 teams look like in two brackets
Eleven entrants sit in a 16-slot draw, so the winners bracket runs 4 rounds — round of 16, quarter-finals, semi-finals and final — and the losers bracket runs 6 behind it. The sheet carries 15 winners boxes and 14 losers boxes, plus the grand final that joins them.
Everybody except the champion has to lose twice, which fixes the total at 20: 10 winners-bracket matches, 9 losers-bracket matches and one grand final. Single elimination for the same 11 entrants is 10, so the second chance costs 10 extra matches. That ratio holds at every size and it is the only honest way to budget the day.
Five of the 16 slots are empty, so five of the 11 entrants skip round one. They are the top five seeds, because a bye is one fewer match to win and that belongs to whoever earned the seeding. On a single-elimination sheet that is the end of the matter. Here it also punches five holes in the losers bracket, which is the part nobody expects.
The 11-team losers bracket, round by round
The 6 losers rounds are 4, 4, 2, 2, 1, 1 boxes wide — 14 boxes in all, of which 9 are played at 11 entrants. They come in pairs: an odd-numbered round takes a fresh batch of beaten entrants from the winners bracket, and the round after it folds the survivors together. Beaten entrants therefore arrive on a timetable — quarter-final losers join at losers round 2, semi-final losers join at losers round 4 and the beaten winners finalist joins at the losers final.
Losers round 2 is 4 boxes wide and it is the one that goes wrong. Drop winners match 1 into losers box 1 and an entrant meets the person who has just knocked them out about half the time, which is precisely what the second life was for. The losers are dropped in reversed here instead, and at 11 entrants that makes the rematch impossible in that round.
Five of the 14 losers boxes cannot be played at all. One of them has nobody on either side and drops out of the tournament entirely: 11 entrants in a 16-slot draw simply do not generate enough first-round losers to fill the opening losers round. The rest are walkovers, marked as such.
Running an 11-team double elimination
20 matches at a quarter of an hour each is about 5 hours of court time. On one court that is a long session; the losers bracket is where the time goes, because 9 of the 20 matches happen in it and none of them can start until the winners round above has finished.
Decide before anybody plays whether the grand final can be reset. If it can, the schedule is 20 matches with a 21th held in reserve. If it cannot, an entrant can win this tournament having lost once, against somebody who has lost nothing — defensible, but only if it was said at the start rather than after the 20th match has gone the wrong way.
15 winners boxes and 14 losers boxes will not share one A4 sheet legibly: 30 boxes carrying 20 matches for 11 entrants. Print the two brackets as separate landscape sheets and pin them side by side, which is how they get used anyway — the winners bracket is watched and the losers bracket is administered.
Common questions
How many matches in an 11 team double elimination bracket?
20, or 21 if the grand final is reset. 10 of them are in the winners bracket and 9 in the losers bracket, because every entrant but the champion has to lose twice and 11 entrants therefore absorb 20 losses.
How many rounds is an 11 team double elimination tournament?
4 winners rounds and 6 losers rounds, then the grand final — 20 matches for 11 entrants. The losers bracket needs roughly twice as many rounds because it folds in a fresh batch of beaten entrants after every winners round: quarter-final losers join at losers round 2, semi-final losers join at losers round 4 and the beaten winners finalist joins at the losers final.
Where do the byes go in an 11 team double elimination bracket?
To the top five of the 11, the same as single elimination — but with a second consequence here. Five of the 14 losers boxes then have no loser coming, because a walkover produces none, so they are marked unplayable on the printed sheet rather than left looking live.
