South London is indeed the biggest part of London by land area, encompassing roughly 59 square miles (153 km²) across many diverse boroughs south of the River Thames. While it covers the largest geographic area compared to other London sub-regions, it is not the most populous, with approximately 1.66 million residents, less than East London’s roughly 2.88 million people. Understanding South London’s size, population, borough composition, and its place within Greater London offers valuable insight into London’s urban geography and development.
Defining South London: Geography and Boroughs
South London is defined broadly as all London boroughs situated south of the River Thames, which acts as a natural boundary from North, East, and West London. It comprises both inner boroughs closer to the city center such as Lambeth and Southwark and outer boroughs including Bromley (the largest London borough by area), Croydon, Kingston, and Richmond. Together, these boroughs form the largest sub-region of Greater London by land size.
Geographic Size: Largest London Sub-Region
South London’s approximate area is 59 square miles (153 square kilometers), making it the biggest part of London geographically. The entirety of Greater London covers around 607 square miles (1,572 km²), so South London constitutes a significant portion of London’s total area. Bromley alone accounts for a large share of this land, helping South London exceed the combined land areas of North or East London boroughs.
Population and Density Comparisons
Although South London is the largest by area, it has a smaller total population density compared to East London. South London houses around 1.66 million people, with a population density of about 4,253 people per km², whereas East London has approximately 2.88 million residents and a higher density exceeding 6,200 people per km².
