Single elimination vs double elimination
One loss and out, or one loss and a second life? The difference in fairness is real, and so is the difference in how long your day becomes.

The core trade-off
Single elimination ends a team’s tournament on the first loss. It is the shortest event you can run and the easiest to schedule, but a single bad half-hour can remove the best team in the field.
Double elimination gives every team a second chance: lose once and you drop into the losers bracket, lose twice and you are out. The winner has to be beaten twice by the end, which makes the result a better answer to "who is best" — at the cost of roughly twice the matches.
The numbers for 8 teams
An 8-team single elimination bracket is 7 matches over 3 rounds. The same 8 teams in a double elimination bracket play 14 matches (2N − 2), across a winners bracket, a losers bracket and a grand final.
That is the whole decision in one line: about twice the court time in exchange for removing the "we lost once and went home" complaint. With one court, double elimination for 16 teams can be a two-day event.
Which one should you pick?
Pick single elimination when time is the binding constraint: a lunchtime office tournament, a school sports day, the last two hours of a festival.
Pick double elimination when teams travelled to be there, when entry fees are involved, or when the seeding is uncertain — the second chance also softens a bad draw.
One practical note: double elimination needs a power-of-two team count between 4 and 32 here. A 5-team double elimination bracket is not offered, because the losers-bracket routing for byes gets genuinely confusing for players standing at the desk.
Frequently asked questions
- How many extra matches does double elimination add?
- For N teams it is 2N − 2 matches instead of N − 1 — 14 instead of 7 for 8 teams, 30 instead of 15 for 16 teams.
- Can I run double elimination with 5 or 7 teams?
- Not in BracketBee: double elimination needs a power of two between 4 and 32. For awkward counts, a single elimination bracket with byes or a round robin works better.
- Can I switch between the two?
- Yes — change the format in the settings panel and the bracket redraws. Scores are cleared when the format changes, because the same match id means something different in each format.
