Which format should your football tournament use?

A league is a round robin. Every team meets every other team, and the table ranks them by points, most often 3 for a win, 1 for a draw, 0 for a defeat. Nobody is knocked out, so a bad afternoon in week two does not end anyone's season.

The cost is the number of matches. A single round robin is n(n−1)/2 games: 6 teams play 15, 8 teams play 28. Home and away doubles it, so 8 teams play 56 and 10 teams play 90. That suits a season of weekly matchdays. It does not fit a one-day event.

A single round robin also leaves home advantage uneven when you have real home grounds. If venues matter, play home and away, or hold the whole event on one neutral pitch.

In JudgeMate: start from Create → Football. For a season, pick a league and switch on Home and away rounds. For a one-day event, pick the round robin format in an event category; the same switch exists there too. Points default to 3/1/0.

A knockout bracket produces a champion in the fewest matches: always one fewer than the number of teams. Sixteen teams play 15 matches, and a field that is not a power of two gets byes in round one.

A drawn knockout match needs a winner on the day. Law 10 of the IFAB Laws of the Game allows extra time of two equal periods of up to 15 minutes each, then kicks from the penalty mark: five each, taken alternately, then sudden death. Some youth competitions skip extra time and go straight to penalties.

Two extras soften the format. A third-place match gives the losing semi-finalists a game and a podium. A consolation round gives the first-round losers one more match among themselves, which matters when teams have travelled for the day.

In JudgeMate: choose the knockout format, then switch on Third-place match and, if you want it, Consolation round for first-round losers. A full consolation bracket, played on to a plate final, is a separate option.

Many club tournaments use this structure, and so does the World Cup. Teams play a small round robin in groups, the top finishers go into a bracket, and everyone gets at least two or three matches before anyone goes home.

Twelve teams in three groups of four play 18 group matches. Take the top two from each group and you have six teams, which does not fill a quarter-final. Add the two best third-placed teams and the bracket has eight. With quarter-finals, semi-finals, a third-place match and a final, the whole event is 26 matches.

The best third-placed teams come from different groups and never played each other, so head-to-head cannot rank them. They are compared on points, then goal difference, then goals scored. The 2026 World Cup took the 8 best of its 12 third-placed teams the same way, without head-to-head. Keep the groups equal in size, or a team from a group of five has played one match more than a team from a group of four.

In JudgeMate: choose groups plus knockout and set the number of groups (1 to 4), how many advance from each group, and how many of the best remaining teams join them (0, 1 or 2). That cross-group ranking uses points, goal difference and goals scored, and needs equal groups. A tie no criterion separates is shown in the group table for you to settle.

In a two-legged tie each team hosts one match and the aggregate score of both decides who goes through. A 2-1 home win followed by a 1-1 away draw is 3-2 on aggregate.

For decades a level aggregate went to the side with more goals scored away from home. UEFA abolished the away goals rule in all its club competitions from the 2021/22 qualifying rounds. A level aggregate in UEFA competitions now goes to extra time at the end of the second leg and then to a penalty shoot-out. Check your own competition's rules, because national cups and youth leagues may skip extra time.

Two legs double the match count of every round. An eight-team knockout over two legs, with a one-off final, is 13 matches instead of 7.

In JudgeMate: in the knockout format, switch on Home and away. Both legs are added up after the return leg, a level aggregate is settled by the shoot-out result, and away goals do not count double. The final stays a single match. The option is not offered in groups plus knockout.

Football rules split into two families when teams finish on the same points.

Head-to-head first. The matches between the tied teams decide before the rest of the table counts. In Spain, article 29 of the RFEF Competition Regulations (formerly article 201 of the General Regulations) separates two clubs first by goal difference in the two matches they played against each other, then by overall goal difference. At the 2026 World Cup, teams level on points in a group were separated first by the results between them.

Goal difference first. The whole season counts before the direct matches. The Premier League separates clubs level on points by goal difference, then by goals scored; head-to-head results come in only after that.

Neither is more correct. Head-to-head rewards winning the big games. Goal difference rewards the season as a whole and punishes collapses against weak teams. Pick one, write it into your rules and publish it before the first match, because the same results can produce a different order.

In JudgeMate: a league has a Tie-break order setting with two presets: head-to-head, then goal difference, then goals scored (the default), or goal difference, then goals scored, then head-to-head. Changing it reorders the whole table, rounds already played included. Tournament group tables always use head-to-head first.

Count matches against pitches and hours before you announce anything. For a fixture list with kick-off times, the schedule maker builds one without an account, and the bracket generator prints a knockout or round robin draw.
