Africa and the Mercator bias, maintained and promoted by...

To our descendants, to our children,

This image above is a perfect visual representation of the Mercator Projection bias, showing how our flat maps often distort the true scale of the world.

​Here is a breakdown of what this image illustrates:

​1. The Map-Maker's Dilemma

​Because the Earth is a 3D sphere (an oblate spheroid), it is mathematically impossible to flatten it onto a 2D surface without some form of distortion. The Mercator projection, which we see most often, was designed in 1569 for marine navigation.

​2. The Illusion of Scale

​The Mercator projection stretches objects as they move away from the equator toward the poles.

• ​Africa sits right on the equator. Because distortion is minimal there, its massive width (7,200 km) is represented more accurately.
• ​Russia is located far to the north. On this map, it is stretched horizontally to a massive degree. While it looks twice as wide as Africa visually, the actual distance shown is only 6,400 km.

​3. Geographic Reality

​In reality, Africa is enormous. It has a landmass of about 30.37 million km². To put that in perspective, you could fit the United States, China, India, Japan, and most of Europe inside the African continent, and still have room to spare.

​Why does this matter?

​Maps aren't just tools; they shape our perception of importance. By making northern countries look larger and southern countries look smaller, the Mercator projection has historically influenced how we perceive the "power" or "significance" of different regions.
