The competition is divided into two stages: group round robin and knockout. Five matches have been played in the group stage, and the team that won three matches in the knockout stage wins. Players can't participate in more than two competitions (each player can only participate in two competitions at most), and the team that gets the top two is eligible to participate in the knockout.
In the knockout stage, the champion and runner-up were decided, and the team that lost in the semi-final tied for third place; The team that lost in the quarter-finals tied for fifth place; The team that finished third in the group stage tied for ninth place. The other two groups play round robin, and the group ranking is decided according to the results.
In addition, not all teams participating in the Sudirman Cup are eligible to win the championship. The Sudirman Cup adopts the "promotion and demotion" system, and only teams participating in A-level competitions are eligible to compete for the championship. After each cup, the last team in the A-level competition will be relegated to the B-level, and it will miss the championship competition in the next competition. The first place in the B-level team can be promoted to A-level.
In the first eight Sudirman Cups, there were only six A-level teams; In the 9th Sudirman Cup, A-level teams expanded to 8 teams; Starting from the 12th Sudirman Cup on 20 1 1, the number of teams participating in the highest-level A-level competition in Sudirman Cup has increased to 12.
