Countries in South America by Size

South American Countries by Size


South America is a continent of great variety, and that also goes for its countries, with the largest occupying a land area close to the size of the entire United States including Alaska, and the smallest country on the continent around the size of Wisconsin. These nations are diverse and quite different, and from huge mountain ranges to amazing coastlines and wonderful scenery, there are plenty of things that make each of the South American nations worth exploring.

This massive country is by far the largest in South America, and it is also the only country on the continent where Portuguese is the predominant language, as opposed to Spanish, which is spoken in most other South American nations. The country has two massive cities with over ten million people each, including the business center of Sao Paulo and the famous beach city of Rio de Janeiro, while the vast rainforest of the Amazon means there are some very remote areas too.

Peru is the third largest of the countries in the region, is roughly twice the size of Texas, and has a similar population to the state, meaning Peru is generally quite low in terms of population density. With parts of the country in the Andes and another region covered by the Amazon forest, this is not necessarily a surprise.

This long strip of land on the east coast of the continent is one of the longest north to south countries in the world, but never reaches over 220 miles from east to west. With a total territory a little larger than Texas, its population is much lower, with the majority of people living in the central area of the country, and the southern part of Chile is very sparsely populated.

The second of South America's landlocked countries is slightly smaller than California and is also relatively sparsely populated. One of the interesting aspects of the country is that it is home to the largest hydroelectric dam on the continent, near the Iguazu Falls, and this electricity plant produces far more electricity than the country needs, exporting most of the energy to Brazil. It is also home to Mennonite immigrants.
