Largest Countries in the World (by Area)

Antique map

When you think about the largest countries in the world, which countries come to mind? The answer would probably depend on whether you’re talking about the largest size in total area or the most populous country. For our purposes, we’re going to focus on the largest countries in square kilometers. This accounts for the surface area which is the land area and the bodies of water in a given country. You can also measure in square miles.

Many people are surprised to learn what countries are in fact the largest by area. While some are no-brainers, others may make you raise an eyebrow. It’s time to test your knowledge as we look at the largest countries in the world by area. See if some of your guesses made the list!

Country Size Matters

As we look at the largest countries in the world by area, there are several factors to consider. These include:

  • How we measure a country’s size
  • How we display a country’s real size

Understanding these concepts will help you understand how countries are ranked according to their total area. Many people don’t realize what goes into measuring a country’s size and often mistake a country’s size.

NOTE: Country rankings aren't definitive; instead they provide an approximate comparison. Country data vary enormously depending on the sources, and there is an absence of reliable data on some countries.

How Do You Measure a Country’s Size?

A country's total area includes its landmass and a region of the sea extending out to (or beyond) its continental shelf. Different countries measure their oceanic area differently, which can lead to some flexibility in the rankings. We've gone with the official areas listed in the CIA World Factbook, but some might argue that we should only measure a country's land area. In that case, the rankings would change slightly. China would be the second largest country, followed by the United States of America, then Canada.

In a surprising change from the norm, as national borders have been fairly fixed for the past decades, Russia has arguably gained area (if one includes Crimea in the count). Crimea would add another 27,000 square kilometers to Russia's already boggling size.

How Do You Display a Country’s Real Size?

Map projections are often discussed when talking about how a country’s real size is displayed. The commonly used Mercator projection can certainly give a false impression of how big different countries are. To fit in a 3D globe onto a flat plane, areas near the poles are stretched out and made bigger. When you take that into consideration, Russia, Canada, and the United States of America are all very big in reality. These three have all held the top three spots, in the order, since the U.S. incorporated Alaska in the 1900s.

What Are the 10 Largest Countries by Area?

Now that we have a better understanding of how a country’s size is measured and how a country’s real size is displayed, it’s time to reveal the world’s largest countries by area.

The countries of the world are diverse in terms of language, in terms of wealth, in terms of culture— they're also very diverse in terms of size. The smallest countries measure just a couple of square miles, and the biggest are absolutely massive. Here are the world's largest countries, listed in order of total area.

What Are the Largest Countries by Continent?

While those are the largest countries when you consider all of the countries in the world, it’s also interesting to look at the largest countries by continent.

This is a bit of a tricky category, since the absolute largest country, Russia, straddles two continents (or not, depending on which model of the continents you follow). "Asian" Russia would still be the largest country in Asia. Greenland is also questionable, since it's technically governed by Iceland.

You’ll notice that Antarctica is not on the list. This is because it has no countries. However, if it was a country itself, it would be the second largest in the world behind Russia.

Using the Seven Continents model popular in the U.S., let’s take a look at the largest countries when you divide them entirely by continent.

Africa

When you look at the countries in Africa, you’ll notice that the size of all of the countries varies. Algeria is the largest while The Republic of Congo is the smallest. Many other countries fall in the middle.

Here’s a fun fact about countries in Africa...several of them are home to well-known landmarks. You can take one of our quizzes to test your knowledge! In the meantime, here’s a look at the largest countries in Africa:

  • Algeria: 2,381,741 sq. km
  • The Republic of Congo: 342,000 sq. km 
  • Sudan: 1,886,068 sq. km
  • Libya: 1,759,540 sq. km
  • Chad: 1,284,000 sq. km
  • Niger: 1,267,000 sq. km
  • Angola: 1,246,700 sq. km
  • Mali: 1,240,192 sq. km
  • South Africa: 1,221,037 sq. km
  • Ethiopia: 1,104,300sq. km

Asia

Asia is home to the fourth largest country in the world, China. Interestingly enough, there are several very small cities in China, such as Hong Kong, which is only 1,110 square kilometers. When you look at other Asian countries, you’ll notice that there are several very small countries, such as Afghanistan and Yemen. This is how several countries in Asia rank when it comes to their size:

  • China: 9,706,961 sq. km
  • India: 3,287,590 sq. km 
  • Kazakhstan: 2,724,900 sq. km

  • Afghanistan: 652,230 sq. km
  • Yemen: 527,968 sq. km

Europe

Compared to countries on other continents, countries in Europe are very small. Even the largest on this list, Turkey, is not that big when you look at the sizes of other countries around the world. You’ll notice that the United Kingdom is not listed as it is under 100,000 square kilometers.

  • Turkey: 783,562 sq. km
  • France: 551,695 sq. km

North America

North America is home to the second largest country in the world, Canada. With more than nine million square kilometers of space, Canada lags far behind the first-place holder, Russia which measures 17 million square kilometers. The USA doesn’t fall far behind Canada when you look at its measurement as it is the second-largest country in North America.

  • Canada: 9,984,670 sq. km
  • The United States: 9,372,610 sq. km

  • Australia: 7,692,024 sq. km
  • Papua New Guinea: 462,840 sq. km
  • New Zealand: 270,467 sq. km

  • Guyana: 214,969 sq. km
  • Uruguay: 181,034 sq. km

Final Thoughts

As you consider all of the largest countries by area, you’ll notice that they range greatly in size. It’s important to note that typically a country’s total area includes its landmass and a region of the sea extending out to (or beyond) its continental shelf. But different countries measure their oceanic area differently, which can lead to some flexibility in the rankings.

It’s also interesting to not only look at the largest countries in the world as a whole but also how they rank within their own continent. Many people often wonder why Antarctica is not on the list. this is because it has no countries to call its own. But, if it was a country itself, it would be the second largest in the world behind Russia.

So, the next time you’re playing a trivia game, impress your friends and win the game when it comes to questions about the largest countries in the world!
