A new system will be used for this tournament. The new format was unveiled in March 2025. This is the third different format in three editions. Despite some slight changes, the format is very adjacent to the format previously used for the European Handball Championship when the tournament still had 16 teams (the format has been discontinued due to the European Handball Championship expanding to 24 teams). Head coach of Croatia,
Ivica Tucak, supports the format change, saying it gives teams a second chance to come back if they stumble earlier in the tournament. •
