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 4 teams look like in two brackets
Four entrants sit in a 4-slot draw, so the winners bracket runs 2 rounds — semi-finals and final — and the losers bracket runs 2 behind it. The sheet carries 3 winners boxes and 2 losers boxes, plus the grand final that joins them.
Everybody except the champion has to lose twice, which fixes the total at 6: 3 winners-bracket matches, 2 losers-bracket matches and one grand final. Single elimination for the same 4 entrants is 3, so the second chance costs 3 extra matches. That ratio holds at every size and it is the only honest way to budget the day.
Four is a power of two, so the draw fills exactly: 2 first-round matches, nobody sitting out, and every one of the 2 losers boxes reachable by somebody. A double-elimination sheet is where an uneven field hurts most, and at 4 entrants it never arises.
The 4-team losers bracket, round by round
The 2 losers rounds are 1, 1 boxes wide — 2 boxes in all, of which 2 are played at 4 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 — the beaten winners finalist joins at the losers final.
At 4 entrants the losers bracket is one box wide the whole way down, so there is no ordering question in it: the 2 first-round losers meet, and the survivor plays whoever loses the winners final. Every larger field has a real choice about which loser drops in where, and most printed sheets make it badly.
Nothing on this sheet is wasted. All 2 losers boxes have two entrants who can reach them, both brackets fill, and the 6 matches are 6 matches somebody actually plays. That is true only because 4 is a power of two.
Running a 4-team double elimination
6 matches at a quarter of an hour each is about 1.5 hours of court time. On one court that is a single evening; the losers bracket is where the time goes, because 2 of the 6 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 6 matches with a 7th 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 6th match has gone the wrong way.
3 winners boxes above, 2 losers boxes below, and the grand final at the end — 6 boxes for 4 entrants, of which 6 are matches somebody actually plays. At 4 slots the whole tournament fits one A4 sheet in landscape at a size people can write in, which is the main reason double elimination gets run at all at this scale.
Common questions
How many matches in a 4 team double elimination bracket?
6, or 7 if the grand final is reset. 3 of them are in the winners bracket and 2 in the losers bracket, because every entrant but the champion has to lose twice and 4 entrants therefore absorb 6 losses.
How many rounds is a 4 team double elimination tournament?
2 winners rounds and 2 losers rounds, then the grand final — 6 matches for 4 entrants. The losers bracket needs roughly twice as many rounds because it folds in a fresh batch of beaten entrants after every winners round: the beaten winners finalist joins at the losers final.
Does a 4 team double elimination bracket need byes?
No. Four is a power of two, so all 4 slots fill, every entrant plays in round one, and both brackets are complete — no walkovers in the winners bracket and no unfillable boxes in the losers bracket.
