How this round robin plan works
Round robin gives every team a match against every other team. It is the fairest common format because no team is eliminated early and final rankings reflect a full set of results.
The trade-off is match volume. With 8 teams there are 28 matches; with 12 teams there are 66. This generator shows the full cost before you commit to the format.
Use the estimate to decide whether a league schedule is realistic for your venue and days. If the total is too high, move to group stage, which keeps multiple games per team while cutting overall match count.
With the current preset, the calculator returns 28 matches across 7 rounds. At 30 minutes per match and 8 matches per day, the event needs about 4 days of scheduled play.

Frequently Asked Questions
+How do I calculate the number of round robin matches?
Use the formula n × (n minus 1) divided by 2. For 8 teams: 8 × 7 / 2 = 28 matches. For 12 teams: 12 × 11 / 2 = 66 matches.
+How many rounds does a round robin take?
An even number of teams needs n minus 1 rounds; an odd number needs n rounds. With 8 teams that is 7 rounds; with 9 teams that is 9 rounds.
+When does round robin become impractical?
Beyond 12 to 16 teams, match count usually exceeds what one or two days can hold. Group stage splits teams into small round robin pools, capping each pool at 4 to 6 matches per team before a knockout.
