Ever looked at a map and felt like Greenland was basically as big as Africa? Yeah, me too. It’s a total lie. Or, well, it’s a cartographic compromise. Most of the maps we grew up staring at in classrooms are based on the Mercator projection, which was designed for sailors in the 1500s—not for people trying to figure out which country actually takes up the most space on this rock we call home.
When you start looking at countries according to size using actual, hard data instead of distorted map shapes, things get weird. Russia is massive, obviously. But did you know you could fit the entire United Kingdom into Canada about 40 times? Or that Brazil is actually larger than the contiguous United States?
Honestly, the way we perceive the world is kinda broken. If you’re planning a trip or just want to win a pub quiz, knowing the real footprint of these nations matters. Let's dig into the actual numbers as of 2026.
The Heavyweights: Russia and Canada
Russia is in a league of its own. It’s huge. We're talking 17,098,242 square kilometers. To put that in perspective, it covers about 11% of the Earth's entire land surface. It spans eleven different time zones. You could take a train from Moscow to Vladivostok and spend a week just watching Russia go by outside your window.
Then there's Canada. It’s the second-largest country at 9,984,670 square kilometers. But here’s the kicker: Canada has more lake area than any other country on the planet. If you drained all that water, it might actually look a lot smaller. It’s a land of extremes, where the province of Quebec alone is over 1.5 million square kilometers—larger than most European countries combined.
The Great Debate: China vs. USA
This is where things get spicy. If you search for the third-largest country, you’ll get different answers depending on who you ask and how they measure "water."

Generally, China and the United States are neck-and-neck. China’s total area is roughly 9,706,961 square kilometers. The U.S. follows closely at about 9,372,610 square kilometers. However, some sources, like the CIA World Factbook, have historically ranked the U.S. higher by including coastal and territorial waters that other countries don’t count in their totals.
- China: Has more actual land. It's roughly 2.2% larger than the U.S. in terms of pure dirt and rock.
- USA: Wins on "total area" in some datasets because of its massive maritime territories and the Great Lakes.
It's basically a tie of giants. Both countries are roughly the same size as the entire continent of Europe. Think about that for a second.
Brazil and Australia: The Southern Giants
Brazil is the king of South America. At 8,515,767 square kilometers, it’s actually bigger than the lower 48 states of the U.S. Most people think of the Amazon, which is fair since 59% of the country is forest, but the sheer scale of the place is hard to wrap your head around. It borders every single country in South America except for Ecuador and Chile.
Then you have Australia. 7,692,024 square kilometers of mostly... well, outback. It’s the only country that is also its own continent. It’s about 1.1 times smaller than Brazil, but because it’s an island, it looks way bigger on some maps. Australia is roughly the same size as the United States (minus Alaska and Hawaii).
India and the Rest of the Top 10
India rounds out the big players at 3,287,590 square kilometers. It’s the seventh-largest country, but it’s the world's most populous as of 2026, with over 1.46 billion people. That means its population density is off the charts compared to places like Canada or Australia.
After India, the numbers start to drop off a bit:
- Argentina: 2,780,400 sq km (the largest Spanish-speaking nation by area).
- Kazakhstan: 2,724,900 sq km (the world’s largest landlocked country).
- Algeria: 2,381,741 sq km (the largest in Africa).
Why Maps Lie to You
We need to talk about the Mercator projection again because it’s the reason your brain thinks Greenland is a behemoth. Because the Earth is a sphere and maps are flat, something has to give. Gerardus Mercator decided to keep the angles right for navigation, which meant stretching everything near the poles.
Greenland looks the same size as Africa on a standard wall map. In reality, Africa is 14 times larger than Greenland. You could fit Greenland into Africa, and still have room for the U.S., China, India, and most of Europe.
Alaska is another victim of this. On a map, it looks like it could swallow half of Brazil. In the real world? Brazil is five times the size of Alaska.
The Practical Side of Size
Size isn’t just a fun fact; it dictates everything from climate to infrastructure.
Managing a country like the Democratic Republic of the Congo (11th largest) is a nightmare for logistics because of its dense jungle and 2.3 million square kilometers of territory. Meanwhile, a country like Kazakhstan has to deal with the sheer isolation of being landlocked and massive.
If you're traveling, don't look at a map of Australia and think, "Oh, I'll just drive from Sydney to Perth for the weekend." That's a 40-hour drive across nearly 4,000 kilometers. For context, that’s like driving from Madrid to Moscow.
Actionable Insights for Your Next Deep Dive:
- Use the "The True Size Of" tool: If you want to see how countries really compare, use online interactive tools that let you drag countries around the globe to see them shrink or grow based on latitude.
- Check the "Land Area" vs. "Total Area": When looking at rankings, always check if the data includes water. It can change the rank of countries like the USA, Canada, and China significantly.
- Don't trust the wall map: If you're teaching kids or learning yourself, look for a "Gall-Peters" projection or a "Winkel Tripel" projection. They aren't perfect, but they represent the actual area of countries much more accurately.
- Think in Population Density: Remember that size doesn't equal power or people. Mongolia is huge (19th largest) but has one of the lowest population densities on Earth, while Bangladesh is tiny (94th) and packed with 176 million people.
Understanding countries according to size is basically a lesson in humility. Our world is vast, but our mental image of it is often just a byproduct of 16th-century sailing charts. Next time you see a map, look at the equator—that's the only place where things are actually as big as they look.
