A single elimination bracket has N minus 1 matches where N is the number of teams. So 8 teams equals 7 matches, 16 teams equals 15 matches.
Single elimination removes a team after one loss. Double elimination gives every team a second chance through a losers bracket before they are removed from the tournament.
Roughly 2 times N minus 1 or 2 times N matches depending on whether the grand final needs a reset. For 8 teams expect 14 to 15 matches.
Choose double elimination when fairness matters more than speed. It is popular for esports, wrestling, and premium youth tournaments where teams travel long distances.
Every team plays every other team exactly once. Standings are decided by wins, points, or head to head. It is the fairest format because a single upset does not end anyone's tournament.
N times N minus 1 divided by 2. So 6 teams equals 15 matches, 8 teams equals 28 matches. Round robins take longer, plan your days accordingly.
Yes. Many clubs run round robin pools first, then take the top finishers into a single or double elimination knockout. Save the setup with a free account to unlock group stage plus bracket workflows.

Single elimination formula: total matches = teams − 1. Rounds = ⌈log₂(teams)⌉.
Double elimination formula: total matches = (teams × 2) − 2 (grand final reset may add 1 more).
Round robin formula: total matches = teams × (teams − 1) / 2. Each team plays teams − 1 games.
Byes: needed when team count is not a power of 2. Byes = next power of 2 − team count.
Plain-English definitions for the terms every tournament director should know.
A team's ranking going into the bracket. The #1 seed is placed opposite the lowest seed so top teams do not meet until later rounds.
