What was Federer's highest ATP doubles ranking?

Federer’s highest ATP doubles ranking was No. 24, reached on 9 June 2003. Although he became far more famous as a singles player, Federer was also an accomplished doubles competitor early in his career and at the Olympics.

His biggest doubles achievement came at the 2008 Beijing Olympics, where he won the men’s doubles gold medal for Switzerland with Stan Wawrinka. Federer also won eight ATP doubles titles and finished with a 131-93 doubles match record according to his career summary.

A common mix-up is confusing No. 24 in doubles with Federer’s singles peak: he reached No. 1 in singles in February 2004. The two rankings measure separate disciplines, and Federer’s doubles ranking was earned during a period when his singles schedule and success increasingly dominated his career.
