I as a kid and adult too saw the countries the way they were shown in any World Map. And I bet you also think the same way too unless you are a Cartographer or Geologist or child of any of the two. Chances are also less that you might be studying or researching on Mercator projection. So, if not, here I bring you something that will give you a completely different perspective on seeing the world.
The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569.
The reason why certain countries looks bigger or smaller than others is because of something called the Mercator Projection. Putting a 3D planet on a two-dimensional map was something of a challenge for early cartographers and so Gerardus Mercator came up with a solution. In 1569 he designed a map that could be accurately used for navigation purposes, but the downside was that his system distorted the size of objects depending on their position relative to the equator. Because of this, landmasses like Antarctica and Greenland appeared much larger than they actually are.
