Rankings measure how players and pairs perform over time, not just at a single tournament. The BWF updates standings weekly using a rolling one-year results window.
Players earn points by competing in graded tournaments and advancing through the draw.
BWF uses a rolling 52-week window — only results from the last year count.
A player's ranking is based on up to 10 of their highest-scoring results in that period.
World rankings are published every Thursday on the BWF website.

Why this matters for players
