You’ve seen it a thousand times. Hanging on the wall of your third-grade classroom. Taped to the back of a library door. It’s the world map of continents, that blue and green rectangle we all use to make sense of the giant rock we live on. But here’s the thing—most of those maps are lying to you. Not because cartographers are evil, but because it’s physically impossible to peel an orange and flatten the skin without it tearing or stretching into something unrecognizable.
Earth is a sphere. Paper is flat.
When you look at a standard Mercator projection, Greenland looks like it’s the size of Africa. It isn't. Not even close. Africa is actually fourteen times larger. This weird distortion messes with our heads. It changes how we perceive the importance of nations and the scale of the Seven Continents. Honestly, the way we define "continent" is kind of a mess anyway. Is it about tectonic plates? Culture? History?
Depends on who you ask.
The Seven Continent Model is Just One Version
Most of us grew up learning there are seven continents: North America, South America, Europe, Asia, Africa, Australia, and Antarctica. But if you head over to Russia or parts of Eastern Europe, they’ll tell you there are six. They combine Europe and Asia into one massive landmass called Eurasia. And they aren't wrong.
If you look at a world map of continents from a strictly geological perspective, Europe and Asia are the same piece of dirt. There is no ocean separating them. The Ural Mountains are the traditional "border," but mountains don't usually define the end of a continent. In much of Latin America, people are taught that North and South America are just one big continent called "America."
It’s all a bit arbitrary.

Take the Olympic rings, for example. There are five. Why? Because the IOC doesn't count Antarctica (no people) and they treat the Americas as one. So, depending on your school system, the "correct" number of continents fluctuates between four and seven.
Geologically, we might even argue for "Afro-Eurasia." That’s a single, continuous landmass containing over half the world’s population. But that doesn't make for a very easy-to-read map.
The Mercator Problem and How It Warps Your Brain
Gerardus Mercator created his famous map in 1569. He wasn't trying to trick anyone. He was trying to help sailors navigate. Because the map keeps lines of constant bearing straight, a navigator could draw a line between two points and stay on course.
The side effect? It stretches the poles.
Look at a world map of continents using the Gall-Peters projection instead. It looks "stretched" and "ugly" to most people because we are so used to the Mercator version. But Gall-Peters shows the actual relative sizes of the landmasses. Suddenly, South America looks huge. Africa looks like a giant. Europe shrinks to a tiny nub.
Dr. Arno Peters, who promoted this projection in the 1970s, argued that the Mercator map was Eurocentric. By making Northern Hemisphere countries look larger, it subconsciously made them seem more powerful. Whether you buy into the politics or not, the math doesn't lie.
Africa is Way Bigger Than You Think
If you take the true land area of Africa—roughly 30 million square kilometers—you can fit the United States, China, India, and most of Europe inside it. Yet, on many digital maps, it looks comparable in size to Greenland, which is actually only about the size of Mexico.
Defining the "Big Seven"
Let’s look at the heavy hitters on the world map of continents through a more nuanced lens.
Asia is the undisputed heavyweight. It covers about 30% of Earth's land area and holds 60% of the population. It’s got everything from the highest point (Everest) to the lowest (Dead Sea). But where does it end? The border with Europe is a squiggly line through the Urals, the Caucasus, and the Turkish Straits. It’s a cultural boundary more than a physical one.
Africa is the only continent that sits squarely across the equator, stretching into both the northern and southern temperate zones. It’s the most "central" landmass on the globe. It is also the most genetically diverse place on Earth. In fact, there is more genetic variation within the continent of Africa than in the rest of the world combined.
North America and South America are linked by the Isthmus of Panama. Fun fact: The Panama Canal is the only reason they aren't technically one continuous piece of land. Geologically, they sit on different plates, which is why we usually split them up.
Antarctica is a weird one. It’s a desert. Seriously. It’s the coldest, driest, and windiest place on Earth. If you looked at a world map of continents that showed what was under the ice, Antarctica wouldn't look like a solid chunk. It would be a series of islands and mountains. The ice is just so thick (up to 4.8 kilometers) that it levels the whole place out.
Europe is technically a peninsula of a peninsula. It’s small, but its jagged coastline and navigable rivers made it a powerhouse for trade and exploration.
Australia is the only continent that is also a single country (mostly). It’s the smallest of the seven, but it’s the oldest geologically. It’s surprisingly flat because it hasn't had much tectonic activity to build mountains for millions of years.
The Continents You Can't See
Think we’ve found them all? Think again.

In 2017, a group of geologists made headlines by "discovering" Zealandia. This is a massive chunk of continental crust that is 94% underwater. New Zealand is just the highest peaks of this sunken continent. If the oceans were drained, your world map of continents would have an eighth member.
Then there’s the Kerguelen Plateau in the Indian Ocean. It’s another submerged microcontinent.
Basically, the map we use is just a snapshot of a specific moment in time with a specific amount of water in the buckets. If sea levels rise or fall, the shapes we obsess over in geography class change completely.
Why the "World Map of Continents" Still Matters
Even with all the distortions and the "Eurasia" debates, these maps are the primary way we organize human knowledge. We use them for climate data, migration patterns, and logistics.
When you look at a map, you aren't just looking at dirt and water. You’re looking at how humans have decided to slice up the world. Understanding that those slices are a bit fuzzy—that "Europe" is a social construct and "Greenland" is tiny—actually makes you better at understanding global affairs.
Actionable Insights for the Curious
- Check out a Globe: If you want to see the world without distortion, a physical globe is the only way. Digital 2D maps will always lie to you.
- Use the True Size Tool: There’s a website called The True Size Of. You can drag countries around and see how they actually compare when you move them away from the distorted poles of a Mercator map.
- Look at the Dymaxion Map: Designed by Buckminster Fuller, this map projects the world onto a 20-sided shape. It has almost no distortion of landmass shapes or sizes and shows the world as one continuous "island" in a single ocean.
- Think Tectonically: Next time you look at a map, try to ignore the country borders. Look at the mountain ranges and the deep ocean trenches. Those are the real borders of our world.
- Question the "Up": There is no reason the North Pole has to be at the top of a map. "South-up" maps are perfectly valid and offer a completely different perspective on how we view the "top" and "bottom" of the world.
Stop trusting the rectangle on your wall. The world is much weirder, and much more interconnected, than a standard projection lets on. Explore the variations, acknowledge the distortions, and realize that every map is just one person's way of trying to make sense of a very big, very round home.
