The aquatics discipline of swimming is considered the flagship event at every edition of the World Aquatics Championships since its introduction in 1973. While open water swimming events were added to the program in 1991, it is considered a separate discipline to swimming.

The number of events competed for at each edition of the championships has grown steadily through the years. In 1973, 29 events were swum: 15 for men and 14 for women, all in the pool. Since 2015, the combined number of events for men and women including pool and open water events has been 49, a drastic increase compared to the first edition. Historically, 50 different events have been held across the 17 editions of the championships.

Long course events have been competed since the inaugural edition of the championships in 1973. The youngest male swimmer to participate in the World Swimming Championships was Ahnt Khaung Htut from Myanmar, who was 12 years old in 2015. He took part at the 100m backstroke and 100m breaststroke events. The youngest female swimmer to participate in the World Swimming Championships was 10 year old Alzain Tareq from Bahrain in 2015. She participated at the 50m butterfly and 50m freestyle events.

Open water swimming events have been competed since the sixth edition of the championships in 1991. From 2000 to 2010, FINA organized in even years specific championships for open water swimming events, being the FINA World Open Water Swimming Championships.

A select number of athletes have won medals at both long course and open water events, including Oussama Mellouli from Tunisia, Hayley Lewis from Australia, Gregorio Paltrinieri from Italy, Florian Wellbrock from Germany, and Sharon van Rouwendaal from the Netherlands.
