Roger Federer’s 237-week reign as world No. 1 is still standing, over a decade after it ended — from February 2004 to August 2008, every single ranking release had his name on top. Novak Djokovic has the far bigger career total, 428 weeks against Federer’s 310, and he still holds the outright record for total time at No. 1. But even Djokovic’s longest unbroken run tops out at 122 weeks — barely half of Federer’s streak. Pete Sampras needed three separate stints just to crack 100 weeks straight.
Total weeks measure a career. Consecutive weeks measure a peak nobody could touch — and on that measure, Federer still stands alone.
