How BWF groups decide who goes through

State the ranking rule before anyone plays

The difficult part of a group table is deciding which column you are allowed to read next. A three-way tie can become a two-way tie. At that point, continuing straight on to point difference can give you the wrong qualifier. Group A below is designed to catch precisely that mistake.

This guide applies Regulation 16 of the BWF General Competition Regulations, version 6.0 (1), in force from 9 November 2024. The players and scores are invented. The top-two qualification rule is our example’s competition format; Regulation 16 ranks the group, but does not by itself decide how many qualify. Check the regulations adopted by your event, including any later amendments.

For planning, a full round robin of n entries needs n × (n − 1) ÷ 2 matches. A knockout of the same entries needs n − 1. Four players therefore mean six group matches rather than three knockout matches. That is the court-time cost before any qualifying knockout begins.

How many players in a group

“Knockout” is the number of matches a bracket for the same players needs. “Rounds” is the fewest time slots the matches fit into, and “Courts” is the most you can use at once. Both follow from the fact that nobody can play two matches at the same time.

Four is a convenient planning example: three matches per player and three rounds of two matches. That is a recommendation, not a BWF limit. The table gives pairing slots, not a timetable with adequate rest. Duration, shared players across events and the event’s rest rules still have to fit. An eight-player group needs 28 matches; a knockout needs seven.

If the top two in each group go through, use a power-of-two number of groups. Two groups send four players to the semi-finals and four groups send eight to the quarter-finals. Three groups would send six, and a six-player knockout needs byes.

Who plays when

Regulation 16.4 recommends an order based on tournament ranking order; it is not a fresh draw for each round. We show the sequences for three to six entries here. In the worked group the numbers are the four seeds, so 1 v 4 is Aarav against Kabir.

In this four-player sequence, each player appears once per round and the first two ranked entries meet last. The rounds are our grouping of BWF’s continuous order into matches with no shared player. A round ending does not establish that everyone has had enough rest for the next one.

1. Group of 3

   1 v 32 v 31 v 2

   Seed 3 plays twice in a row. With three players, someone has to.

2. Group of 4

   1 v 42 v 31 v 32 v 43 v 41 v 2

3. Group of 5

   1 v 52 v 43 v 51 v 42 v 51 v 34 v 52 v 33 v 41 v 2

   One player sits out each round, and each player sits out exactly once.

4. Group of 6

   1 v 62 v 43 v 51 v 42 v 53 v 61 v 32 v 64 v 52 v 31 v 54 v 65 v 63 v 41 v 2

Regulation 16.5 overrides that recommended order: matches between players from the same Member must be completed first. “Member” means the national association here. Extending that policy to a shared club or academy would be a local competition choice. Publish it as such; do not present it as the wording of 16.5.

Group A, match by match

Take a club championship with four seeds in Group A: Aarav 1, Vihaan 2, Arjun 3 and Kabir 4. They play in the order above, and the scorer writes down every game score, because the tie-break rules need them.

In every row the winner’s figure comes first. Points are the totals across all games in the match, including games the winner lost.

The same results as a grid show the whole group at once. Read along a row for that player’s games against each opponent.

Adding up each player’s matches, games and points gives this.

Kabir lost all three and finishes fourth. The other three have two wins each, and only two of them can go through.

Breaking ties between players who finish level

For singles and doubles, follow Regulations 16.2.1–16.2.4.2. Count how many entries remain tied at each stage. That count determines the next comparison.

1. Matches won

   The player with more wins ranks higher. Games and points play no part yet.

2. Two players level: their own match

   Regulation 16.2.2: with exactly two level on wins, the winner of their match ranks higher.

3. Three or more level: game difference

   Regulation 16.2.3: games won minus games lost across all group matches. Higher ranks first.

   If that leaves exactly two level, their own match decides.

4. Still three or more level: point difference

   Regulation 16.2.4: points won minus points lost across all group matches. Higher ranks first.

   If that leaves exactly two level, their own match decides again.

5. Still three or more level: draw lots

   Regulation 16.2.4.2 requires lots. Holding the draw openly and recording it is a sensible local procedure.

Regulations 16.2.3.1 and 16.2.4.1 explicitly return a remaining two-way tie to head-to-head. Point difference is not an automatic next column after game difference.

Applying it to Group A

1. WinsKabir has none and is fourth. Aarav, Vihaan and Arjun have two each, so three players are level and the next step is game difference. Their own matches can’t separate them, because Aarav beat Vihaan, Vihaan beat Arjun and Arjun beat Aarav (see the diagram below).
2. GamesAarav is +3, Vihaan +1 and Arjun +1. Aarav is first, and Vihaan and Arjun are left level.
3. Head-to-headWith exactly two level, their match decides. Vihaan won it 2–1, so Vihaan is second and goes through.
4. PointsArjun’s +20 is the best point difference in the group, but it is never consulted. Once the ladder is down to two players it goes back to their match, not on to points.

Mistakes that change the result

A 21–19, 21–19 win and a 21–3, 21–2 win each contribute +2 to game difference. Their point differences are very different. That difference matters only if the regulations take the tie that far.

When only two players are level on wins, game difference isn’t used at all. The match between them decides, even if the loser has the better game difference over the whole group.

Game and point differences are totals over all of a player’s group matches. That is what the regulation says: total games, total points. A mini-table built only from the matches among the tied players gives different answers. Aarav’s +3 includes the win over Kabir.

Regulation 16.2.5 can change the table more substantially: if a player or pair cannot complete all group matches, their results are deleted from the group calculation. A retirement during a match counts as non-completion. Suppose Kabir retires during the match against Arjun in round 3. Remove Kabir’s results and recalculate using only the three remaining players’ matches:

Everyone now has one win. Game difference puts Arjun second and Vihaan third. Their head-to-head has not changed, but the table reaches a different decision because the three players are no longer tied on game difference. Include the withdrawal rule in the pre-event explanation.

For a local event, consider simultaneous final-round matches where courts and rest requirements allow. That reduces one match’s information advantage. It is an organising recommendation, separate from Regulation 16’s ranking calculation.

Setting up groups for your own event

Separate the competition choices from the ranking calculation. The following are local planning suggestions, not additional clauses of Regulation 16.

1. Decide the groups. Aim for four players in each, and a power-of-two number of groups. Eight players make two groups of four and sixteen make four. Three per group is acceptable, and five is about the limit unless you have courts to spare.
2. Publish the seed-placement method under your event’s draw rules. The snake below is one illustration: A, B, B, A, then repeat. Regulation 16 is not authority for choosing that placement method.
3. Print the named order of play. Apply the same-Member requirement where it governs the event; use any same-club extension only if your local regulations adopt it.
4. Record every game score as it is played. The umpire’s score sheet already has them.
5. Put the ranking order and the withdrawal rule on the group sheet, where players can see them before the first match.
6. With two groups, the usual pairing for the knockout is first in A against second in B, and first in B against second in A. That keeps the two group winners apart, and each group’s top two apart, until the final.

Eight seeds placed A, B, B, A, A, B, B, A. The seed numbers in each group add up to 18.

Keeping the tally

You need one table, which you can draw on the group sheet: a row for each player, with matches won, games won–lost, game difference, points won–lost and point difference, like the tally in the worked group. After each match, add the two players’ numbers to their rows. The sums are small enough to do by hand.

When the last match is in, start with wins and see who is level. If it is exactly two players, read their match. If it is three or more, compare game difference. Sorting the table by wins, then games, then points won’t do the job, because a plain sort skips the head-to-head step, and in Group A it would put Arjun above Vihaan.

Group sheets to download

We have made sheets for a group of four, with BWF’s order of play already filled in. Print the PDF and keep the group on paper, or use the spreadsheet and let it work out the ranking.

The workbook has a blank tab and an example tab with Group A in it. Enter the players, then the games won and total points for each match. It tallies the group and applies the ladder, including head-to-head, and shows which step decided each place. If three or more players are level on everything, it says to draw lots. If a player withdraws, clear all of that player’s scores first.

Team events

For team competitions, first distinguish the tie between teams from the individual matches within it. Regulation 16.3 ranks teams by ties won. The event regulations define the tie’s composition and any format-specific changes; the singles-and-doubles ladder cannot simply be copied across.

The ladder is longer because there are more levels to count. Under Regulation 16.3, three or more teams level on ties won go to the difference between ties won and lost, then to matches, then games and then points, with lots as the last resort. Whenever only two teams are left level, the tie between them decides.

Whenever the ladder is down to exactly two level teams, the tie between them decides again.

Withdrawals work a little differently too. Under 16.3.7, a team unable to complete its group ties loses its group results. Under 16.3.8, non-completion of one match inside a tie is treated differently: that match counts as completed without the conceding side scoring another point. Do not apply the individual-group deletion rule to that single match.

An event-specific regulation can replace parts of this general ladder. Establish which regulations govern before calculating places. A correctly added table can still apply the wrong competition rules.
