Mercator Vs True Size of Each Country

Map found via reddit, click for larger version
While it’s well known that the mercator projection distorts the world, the maps here show very clearly by how much. Countries close to the equator barely change, whereas countries further north shrink dramatically.

The maps are all the work of climate data scientist @neilrkaye.

You can see an animation below:

The map also gives a bar graph to show the relative size of the world’s largest countries:

Finally, here’s an example to what happens to Mexico and Greenland when you swap them:

      That’s simply not possible, or you have to distort the shape of each country. It’s simply not possible to project the correct size AND shape from a globe to a flat map. See e.g. Gall-Peters projection that retains the correct size, but not the shape.

        Maybe, if that is the correct size, the earth is not a globe, but a flat plane.

      you just have to type “world map” in google to find what you requested.

    Loved your maps. Especially that gif which scales down the distortion due to Meractor projection. That was awesome! May I use your images on Quora?

      As long as you give credit back should be fine.

    Really cool projection, but it appears the world doesn’t fit together anymore. Are you planning on finishing the Atlas?

    Well done! Nicely highlights the impact of using conformal vs. equal are projections.

    Interesting! It completely breaks my understanding of world geography!

    My impression is that terrestrial globes do not more accurately represent country sizes. Is that right? If so, why? Are globes more accurate? Could they be?

    Thank you so much for your brilliant work. But why don’t you put the countries in the real size together, like Mercator? – Mercator should be canceled.

    I think it’s brilliant – such a simple and clever way of demonstrating the Mercator distortion.

    Can I ask you to reconsider your response of 5 Dec 2021? Could one take the Mercator projection map of the world ( as you have) and place at the ‘centre of gravity’ of each country not a scaled version of the Mercator projection but a scaled version of a gnomonic projection of that country with its ‘tangent point’ placed on that country’s centre of gravity.
    Yes, that’s a different tangent point for each country.
    Is it doable? Or a disproportionate ( sorry for the pun) amount of work

    Thank you
