ATP No.1 Ranking by Weeks: All-Time Historical Analysis

The ATP World No.1 ranking represents the pinnacle of men's professional tennis, determined by a 52-week rolling points system. Novak Djokovic's 428+ weeks at No.1 is the all-time record, a testament to sustained dominance across surfaces. This guide analyzes every aspect of the No.1 ranking.

Federer held the record for consecutive weeks at No.1 with 237 weeks from February 2004 to August 2008. Djokovic's longest streak was 122 weeks. Connors held 160 consecutive weeks in the 1970s. These streaks require exceptional consistency across all four Grand Slams and Masters events.

The youngest No.1 in ATP history is Carlos Alcaraz, who claimed the top ranking at 19 years and 4 months after winning the 2022 US Open. Federer became the oldest No.1 at 36 years old. Hewitt reached No.1 at 20, while Connors first topped the rankings at 22.

The current ATP ranking system awards 2,000 points for a Grand Slam title, 1,000 for Masters 1000 events, and lesser amounts for lower-tier tournaments. A player's ranking consists of their best 19 results over 52 weeks. This system rewards consistency and punishes extended absences, making prolonged No.1 tenures especially impressive.
