The format you pick decides almost everything else about your tournament: how many games you need, how much gym time to book, how long teams stick around, and whether a team that drove an hour goes home after one bad half. Here's how the four common basketball formats compare, with the math you need to plan each one.
The quick answer
| Format | Games for 8 teams | Guaranteed games per team | Best for |
|---|---|---|---|
| Single elimination | 7 | 1 | One-day events, tight gym time |
| Double elimination | 14 | 2 | Competitive fields that want a second chance |
| Round robin | 28 | 7 | Small fields (4–6 teams), leagues |
| Pool play → playoffs | 12 + 7 = 19 | 3 | Most weekend tournaments |
(Pool play row assumes two pools of four, with every team advancing to an 8-team playoff. Advance fewer teams and you need fewer games.)
Single elimination
Lose once and you're out. It's the simplest bracket and the fastest to run: N teams play N − 1 games, because every game eliminates exactly one team and all but the champion get eliminated. Eight teams need 7 games across 3 rounds; sixteen teams need 15 games across 4 rounds.
If your team count isn't a power of two (4, 8, 16, 32), the top seeds get byes — a free pass into round two. Twelve teams in a 16-slot bracket means four byes, which go to seeds 1–4.
The catch: half the field plays one game. If teams paid a real entry fee or traveled to get there, that stings. Single elimination works best for free events, short evening tournaments, or as the playoff stage after pool play.
Double elimination
Teams are out after their secondloss. Losing in the winners bracket drops you into the losers bracket, and the winners of both brackets meet in a grand final. You'll need roughly 2N − 2 games(plus one more if you play an “if necessary” reset game when the losers-bracket team wins the first final). Eight teams: about 14 games.
Every team is guaranteed two games, and the bracket rewards the best team rather than the luckiest one. The trade-off is time: the losers bracket runs long, and the last few rounds can't be played in parallel. Double elimination is easiest with 4, 8, 16, or 32 teams — that's also what Tipoff supports for this format today, with a single grand final.
Round robin
Everybody plays everybody once. The game count grows fast: N × (N − 1) ÷ 2. Four teams need 6 games, six teams need 15, and eight teams need 28. Standings are decided by record, then tiebreakers (Tipoff uses wins, then point differential, then points scored).
Round robin is the fairest format and gives every team the most basketball, which is why leagues use it. For a one-day tournament it only really works with four to six teams — or as the first stage of pool play.
Pool play into playoffs
The format most weekend tournaments use: split the field into small round-robin pools (usually 3–4 teams), then seed the top finishers into a single-elimination playoff. Every team gets at least two or three games, and the bracket still ends with a real championship game. We break it down in detail in What is pool play?
How to estimate your gym time
The formula that matters when you're booking courts:
Example: pool play with 12 teams (three pools of four) is 18 pool games. Add an 8-team playoff (7 games) and you're at 25 games. On two courts with one-hour slots, that's about 13 hours — a two-day weekend. On four courts, it fits in one long Saturday.
Also remember that later rounds can't all run at once: a final can't start until both semifinals finish, so your last couple of hours will leave courts empty. Build in buffer.
Which should you pick?
- Charging an entry fee or teams traveling? Pool play or double elimination — guarantee at least two games.
- One gym, one evening, free event? Single elimination.
- Four to six teams? Round robin, optionally with a championship game between the top two.
- Multiple age groups or skill levels? Run separate divisions, each with its own format.
On Tipoff you pick the format per division, and the app seeds the bracket and builds a timed schedule across your courts in one step — so you can try each format against your real team count and court hours before you commit. Start with our step-by-step setup guide.
