GLOBAL — Russia remains the world’s largest country by total area, covering about 17.1 million square kilometres, while Canada, the United States and China occupy the next positions under commonly used international area comparisons. Nigeria, with approximately 923,768 square kilometres, ranks among the world’s larger countries but sits well below the top 20.

A widely shared ranking of country sizes offers a useful snapshot of the enormous differences in national territory. However, some figures and labels need clarification: rankings can change depending on whether they count land alone, inland water, coastal waters or overseas territories. Some lists also include dependent territories and special administrative regions alongside sovereign countries.

The World’s Largest Countries

Using the commonly cited total-area figures, the leading countries are:

  • Russia: 17,098,242 km²
  • Canada: 9,984,670 km²
  • China: 9,596,960 km²
  • United States: approximately 9.5 million km², depending on the treatment of coastal and territorial waters
  • Brazil: approximately 8.5 million km²
  • Australia: approximately 7.7 million km²
  • India: approximately 3.29 million km²
  • Argentina: approximately 2.78 million km²
  • Kazakhstan: approximately 2.72 million km²
  • Algeria: approximately 2.38 million km²

Russia’s territory stretches across eastern Europe and northern Asia, making it larger than any other country by a considerable margin. Canada is second in the conventional total-area ranking, while China and the United States are close enough that their order can depend on the measurement standard used. The United States is placed third in some datasets that count additional waters, while China is third in others.

Where Nigeria Stands

Nigeria covers approximately 923,768 square kilometres, according to the World Bank’s 2024 surface-area data. It is Africa’s 14th-largest country by area, behind countries including Algeria, the Democratic Republic of the Congo, Sudan, Libya, Chad, Niger, Angola, Mali, South Africa, Ethiopia, Mauritania, Egypt and Tanzania, depending on the dataset and territorial definitions applied.

Nigeria is larger than several countries that are economically or geographically prominent, including the United Kingdom, Ghana, Uganda, Portugal and South Korea. Its land area also makes it substantially larger than many European states. Yet size alone does not determine population, economic output, natural-resource wealth or political influence.

Important Corrections And Differences In The Viral List

Canada’s figure: The widely accepted total area of Canada is about 9.98 million km², not the much larger 15.6 million km² figure that appears in some World Bank surface-area tables. Different source conventions and water-area accounting can produce substantial discrepancies, so figures should not be mixed within one ranking.

United States and China: The two countries are close in area. A ranking should state its measurement method rather than imply that their positions are universally settled. The CIA World Factbook’s 2025 figures list the United States at 9,826,675 km² and China at 9,596,960 km², placing the United States ahead under that dataset.

France: France is often listed at around 551,000 km² when only metropolitan France is counted. Its total area is larger when overseas departments and regions are included. The figure must therefore specify whether it refers to mainland France or the French Republic’s full territory.

Denmark: Denmark proper is relatively small, but the Kingdom of Denmark also includes Greenland and the Faroe Islands. Including Greenland dramatically changes the total. A list that gives Denmark about 43,000 km² is referring to Denmark proper, not the entire kingdom.

Macao: Macao is not a sovereign country. It is a Special Administrative Region of China and should be separated from a ranking of independent countries. Monaco, by contrast, is a sovereign state and covers about 2 square kilometres.

Largest Is Not The Same As Most Populous

Territorial size is only one way of comparing countries. Russia is the largest by area, but India is the world’s most populous country. Bangladesh, despite its relatively small territory, has a very large population, while Australia occupies a vast area with a comparatively small population.

Population density, climate, geography, infrastructure, natural resources and the distribution of habitable land all influence how national territory is used. Large desert, mountain, tundra or forest regions may contribute substantially to a country’s area without supporting dense settlement.

The ranking is therefore best understood as a measure of geographical extent rather than national strength or development. It also highlights why clear definitions matter: a country’s position can shift when inland waters, coastal waters, overseas regions or associated territories are counted differently.
