History of Badminton Scoring: From 15 Points to Rally Scoring
Modern badminton uses rally scoring to 21 points, but the sport wasn't always scored this way. For over a century, badminton used a side-out scoring system where only the server could score — and men played to 15 while women played to 11. Here's how and why that changed.
Origins of Badminton
Badminton evolved from battledore and shuttlecock, a game played for centuries across Europe and Asia. British military officers stationed in India during the 1860s played a competitive version with a net, bringing it home to England.
In 1873, the Duke of Beaufort introduced the game to guests at his country estate, Badminton House, in Gloucestershire. The sport took its name from the house. By 1877, the Bath Badminton Club had published the first formal rules — including the 15-point scoring system that would last for over a century.
The Original 15-Point System
Under the traditional scoring system used from the sport's formalization until 2006:
The biggest criticism of this system was unpredictable match lengths. With side-out scoring, rallies where the server lost produced no score change — matches could stall for extended periods, making TV scheduling nearly impossible.

First Written Rules
The Bath Badminton Club publishes the first codified rules. Men's games to 15 points, women's to 11 points, side-out scoring only.
BWF Founded
The International Badminton Federation (now BWF) is established, standardizing rules internationally across member nations.
Olympic Debut
Badminton appears at the Barcelona Olympics — still using the traditional 15-point side-out system. Singles and doubles events included.
5x7 Experiment
BWF trials a radical new format: best of 5 games to 7 points with rally scoring. Tested at select events but abandoned — too many stoppages, players disliked the format.
21-Point Trials
BWF tests 21-point rally scoring at selected tournaments. The response from players, broadcasters, and fans is overwhelmingly positive.
Rally Scoring Adopted
BWF officially adopts 21-point rally scoring for all sanctioned events. Games to 21, win by 2, cap at 30. No more side-out. Same rules for men and women.
11x5 Proposed
BWF proposes switching to best of 5 games to 11 points for shorter, more TV-friendly matches. Member nations vote against the change.
11x5 Revisited
The 11-point format is discussed again at BWF council. Once again, it fails to gain enough support. The 21-point system remains.
Why BWF Changed to Rally Scoring
The switch to rally scoring in 2006 was driven by several factors, all connected to making badminton more viable as a spectator and broadcast sport:
TV Broadcasting
Predictable match lengths (45-90 minutes) made scheduling reliable for broadcasters. Side-out matches could run 2+ hours unpredictably.
Spectator Engagement
Every rally produces a point. No more 'dead' rallies where the score stays the same. Fans can follow the action easily.
Fairness
Side-out scoring gave an advantage to the player who won the toss and chose to serve first. Rally scoring neutralized this.
Gender Equality
The old system had different point totals for men (15) and women (11). The new system uses 21 for everyone.
Commercial Viability
Sponsors and event organizers needed consistent broadcast windows. Rally scoring delivered this reliability.
Simpler Rules
No more setting, no more side-out complexity. Score on every rally, first to 21, win by 2. Easy for new fans to understand.
Old vs New System Comparison
| Old System (pre-2006) | Current System (2006+) | |
|---|---|---|
| Points per game | 15 (men) / 11 (women) | 21 (all) |
| Scoring type | Side-out (serve to score) | Rally point (every rally) |
| Deuce rule | 'Setting' at 13/14-all | Win by 2 at 20-20, cap 30 |
| Gender difference | Yes (15 vs 11) | No (21 for all) |
| Avg match length | Unpredictable (1-2.5 hrs) | 45-90 minutes |
| Games per match | Best of 3 | Best of 3 |
| Mid-game interval | None standard | 60 seconds at 11 |
Impact on the Sport
Rally scoring fundamentally changed how badminton is played and watched:
- Attacking play:With every rally worth a point, aggressive play is rewarded more. Players can no longer afford to play safe — losing a rally always costs a point.
- Fitness:Matches became more physically demanding. Every rally matters equally, so players must maintain peak intensity throughout. Fitness became a bigger differentiator.
- Comebacks:Rally scoring makes comebacks more possible. The receiving side scores directly instead of needing to win serve first, then win another rally to score.
- TV growth:Predictable scheduling and constant scoring action made badminton far more attractive to broadcasters. Olympic and World Championship viewership increased significantly.
- Accessibility:Simpler rules made the sport easier for new fans and casual players. No more explaining side-out or setting — just "score on every rally, first to 21."

Frequently Asked Questions
When did badminton change from 15 to 21 points?
The BWF officially adopted the 21-point rally scoring system in 2006, replacing the old 15-point (men) / 11-point (women) side-out system. The change took effect for all BWF-sanctioned tournaments immediately. The 2006 Thomas and Uber Cup was among the first major events under the new rules.
What was the old badminton scoring system?
Under the old system, men's singles and all doubles were played to 15 points, while women's singles was played to 11 points. Only the serving side could score — if the receiving side won a rally, they gained the serve but no point (side-out). At 13-all or 14-all (9-all or 10-all in women's), the player who reached that score first could choose to 'set' the game, extending it by a few extra points.
Why did badminton change to rally scoring?
The BWF changed to rally scoring primarily to make matches more TV-friendly with predictable durations (45-90 minutes vs potentially 2+ hours). Rally scoring also made every rally exciting for spectators, removed the complexity of side-out rules, and eliminated the scoring difference between men's and women's games.
What is 'setting' in old badminton rules?
Setting was a rule in the old 15-point system. When the score reached 13-all, the player who first reached 13 could choose to 'set' the game to 5 more points (playing to 18), or continue to 15. At 14-all, the game could be set to 3 more points (playing to 17). In women's 11-point games, setting was available at 9-all (set to 3, play to 12) and 10-all (set to 2, play to 12). Setting added a tactical element that no longer exists.
Has badminton always been best of 3 games?
Yes, badminton has consistently used a best-of-3 format for individual matches throughout its modern history. The BWF briefly experimented with a best-of-5 format to 7 points (with rally scoring) in 2002, but this 5x7 system was abandoned after trials. The current best-of-3 to 21 points has been the standard since 2006.
Could the scoring system change again?
It's possible. The BWF periodically reviews the scoring system. In 2014, they proposed an 11-point, best-of-5 format to shorten matches further for TV, but member nations voted against it. In 2018, a similar proposal for 11x5 was again discussed but not adopted. Any future changes would need to be approved by BWF member associations.
