Why Map Projections Matter: The Mercator Misconception

Here is a simple truth: All flat maps are wrong.

The Earth is a sphere (well, an oblate spheroid). A map is a flat piece of paper or a 2D screen. It is mathematically impossible to flatten a sphere without distorting something. You have to sacrifice shape, size, distance, or direction.

The choices map-makers (cartographers) make about what to distort have shaped our view of the world for centuries—often leading to significant misconceptions.

The Villain? The Mercator Projection

The most famous map in the world is the Mercator Projection, created by Gerardus Mercator in 1569. It became the standard for navigation because it preserves straight lines. If you draw a line from London to New York on a Mercator map, that is the constant compass bearing you need to sail.

However, the cost of this navigational utility is massive distortion of size as you move away from the Equator.

The Greenland Problem

On a standard classroom Mercator map:

  • Greenland looks roughly the same size as Africa.
  • In Reality: Africa is 14 times larger than Greenland. You can fit the USA, China, India, and most of Europe inside Africa.

The European Bias

Because the distortion enlarges the northern hemisphere (where Europe and North America are), it subconsciously reinforces a view where these regions are "larger" and more dominant than the countries near the equator (Africa, South America, South Asia). It literally makes the Global North look bigger than the Global South.

Other Viewpoints

To correct this, other projections have been proposed:

  • The Gall-Peters Projection: This map preserves area accurately. Africa looks enormous (correctly), and Europe looks quite small. However, it distorts the shape of countries, making them look stretched and "melty."
  • The Winkel Tripel: Used by National Geographic, this is a compromise projection. It tries to balance size and shape distortion so that nothing is too extreme. It looks the most "right" to the human eye.

The Solution: Go 3D

The only accurate way to view the world is on a globe. That’s why digital mapping has been such a breakthrough. When you zoom out on Google Earth (or in the game modes on Atlas Arcade), you are seeing a 3D representation. Greenland is small. Africa is huge. The Pacific Ocean covers nearly half the planet.

At Atlas Arcade, we use dynamic globe visualizations whenever possible to give you the truest representation of our world. We believe that understanding the true scale of nations is the first step in understanding the true scale of our global community.

Next time you look at a wall map, remember: it's lying to you. And that's okay, as long as you know how.
