Under 9 Badminton Rules: Denmark's 2026/27 Format

Last checked: August 2026 · Written by the Badminton House player-led team.

These under 9 badminton rules belong to Badminton Danmark and DGI's Danish competition format for the 2026/27 season. They are not universal BWF laws for every U9 player. A province, country, club, or event may define its junior age groups and playing format differently.

This guide turns the current Danish documents into a court-and-event checklist. Confirm your own competition regulations before copying it, especially if you are outside Denmark or preparing for a later season.

What are Denmark's under 9 badminton rules in 2026/27?

Under Badminton Danmark and DGI's 2026/27 U9 format, play uses a shorter court, a 145 cm net, and best-of-three games to 15. Singles occupies one half of the court; doubles keeps the full width. In both, the rear doubles service line becomes the back boundary.

Badminton Danmark and DGI describe the scaled game as intended to fit children's physical and mental prerequisites, create more quality contacts and more even matches, and support age-appropriate learning. Those are the organisers' stated aims, not guaranteed outcomes for every child.

Keep the attribution beside the numbers when sharing the table. “Denmark U9, 2026/27” tells a parent or volunteer exactly what the measurements describe and prevents the sheet being mistaken for a permanent international rule.

Where are the U9 court lines, and how high is the net?

Under Badminton Danmark and DGI's 2026/27 U9 court rules, singles uses the centre division and outside doubles sideline to create a half-width court, while doubles uses both outside doubles sidelines. Both stop at the rear doubles service line. Lower the net to 145 cm and measure it before play.

Mark U9 singles: half width and shorter length

Each player uses the matching half on the opposite side of the net. The outside boundary is the doubles sideline, not the narrower ordinary singles sideline. The inside boundary follows the court's centre division. Because the painted centre service line does not normally continue all the way to the net, extend the division visibly with suitable court tape where the organiser guide calls for it.

At the rear, the doubles long service line is now the back boundary. The strip between that line and the standard back line is out. Name the line during the briefing instead of saying only “short court”; players and scorers then know which existing marking decides a close call.

Mark U9 doubles: full width and the same shorter length

Both doubles sidelines remain in, so no width conversion is needed. The rear doubles service line again becomes the back boundary on both sides. This is the simplest memory rule: U9 singles and doubles share the same reduced length, while singles uses half the width and doubles uses all of it.

Measure 145 cm; do not copy the old video measurement

The current official page says the net height for both U9 and U11 is 145 cm from 2026/27. It also warns that the practical setup video was made for the earlier 135 cm U9 height. The demonstration may show how a net can be adjusted, but its old target number is not current.

Bring a measuring tape or net-height gauge. Do not use a racket head as a ruler and do not estimate by appearance. Measure, adjust, measure again, then check that the net and any temporary court tape are secure before the first warm-up.

How does scoring work, and what changed from 2025/26?

Under Badminton Danmark and DGI's 2026/27 U9 scoring rules, singles and doubles use best-of-three games to 15. A side needs a two-point lead, so 15–14 continues and 16–14 finishes. The cap is 21: at 20–20, the next rally ends the game at 21–20.

• 15–13: game finished; the leader has reached 15 and leads by two.
• 15–14: continue; the lead is only one.
• 16–14: game finished; the lead is two.
• 20–20: play one more rally.
• 21–20: game finished at the cap.

Use the 145 cm measurement established in the court setup above. Replace the superseded 135 cm figure on any reused diagram, volunteer note, invitation, or checklist.

Do not confuse a break between separate matches with an interval inside a match. The current organiser guide allows ten minutes between matches in the event format it describes, with a shorter break by agreement. That is a scheduling rule for this context, not a universal BWF interval between games.

How should an organiser run the Danish U9 event format?

Choose pools or Swiss Ladder after the entry count is known, then verify that the draw supplies the intended amount of play. The 2026/27 guide plans for four to six singles and two to five doubles matches per player. Publish the court, net, score, and rest rules before the event.

The official 2026/27 U9 and U11 organiser guide changes the event structure with participant numbers. Avoid summarizing that as “everyone plays everyone.” A pool may suit one entry count, while Swiss Ladder can repeatedly pair players on results when the field is larger or levels are not known in advance.

Use the guide's participant-count table after entries close. This article explains the two available structures, but it does not replace that table or give the organiser discretion to choose by preference alone. Record the entry count, open the current-season row, and copy its recommended structure into the working schedule.

After copying the structure assigned by the official participant-count table, check the promised match range player by player. A draw that looks balanced on paper still needs enough court slots to deliver the stated four to six singles and two to five doubles matches.

Before publishing, assign one organiser to audit every player's singles and doubles total against the chosen row. Mark any court or timing conflict on the working draw, correct it, and repeat the count before sending schedules to families and volunteers.

1. Confirm scope. State “Badminton Danmark/DGI U9, season 2026/27” on the working sheet.
2. Close entries before fixing the draw. Use the guide's participant-count format rather than forcing every field into one bracket.
3. Count player opportunities. Check for four to six singles and two to five doubles matches per player.
4. Prepare the physical court. Measure 145 cm, mark the half-court division, and brief the rear boundary.
5. Separate scoring from scheduling. Put 3 × 15 on the scorecard and the between-match rest in the timetable.
6. Repeat the briefing. Tell players which sideline and rear line apply before their first match.

For a mixed-gender entry list, follow the guide's current boys' singles, girls' singles, and combined doubles categories rather than inventing another division. If a local sanctioning body publishes a different category or draw rule, that local event document controls.

After entries close, return to the official participant-count table, confirm the draw row, and check every player's scheduled match total before publishing the event.
