  A world map for everyone
  The Equal Earth Wall Map is for schools, organizations, or anyone who needs a map showing countries and continents at their true sizes relative to each other. Africa appears 14 times larger than Greenland as it actually is. And wherever you live, the map has you covered. Download a choice of three versions centered on these regions: Africa/Europe, the Americas, and East Asia/Australia.
  Other features include:
  •  It’s free. Download the map and print as many copies as you want.
  •  It’s big. The map measures 55” wide x 29” tall (1.4 x 0.74 meters). You can print it even larger thanks to the very high resolution.
  •  Just enough detail.  The 2,600+ map labels provide geographic context without overwhelming you with too much information.
  •  Professional design. With pleasing colors, readable type, and clear visual hierarchies, this is a map that you will want to look at.

We have a map that works fine, it’s called a globe.

I bet you can even find some that are the correct oblate spheroid.

It really is kind of unfortunate that the Earth is an oblate spheroid. It complicates a lot of things. I’ve been a fairly vocal proponent of stopping the Earth’s spin to eventually correct for this (we hope).

That would further simplify things by wiping out human life on Earth. Nuclear submariners might last a few years.

For a one foot diameter globe, the diameter difference would be about 1mm. You couldn't tell without calipers or such. A typical commercial globe will be more oblate than that unintentionally.

The Generic Mapping Tools (GMT) supports a lot of projections, their documentation is well worth a browse: https://docs.generic-mapping-tools.org/6.0/cookbook/map_proj...

Technically it does not shrink Africa’s size but it inflates the apparent size of northern and southern areas.

It seems clear that the problems of African developement can be fixed by topping the evil cadre of cartographers that keep it down. On the other hand, Africa has an obvious advantage by coming first in alphabetical order.

Africa has also been in the middle of most world maps for a long time.

We have the technology to fix this: all maps should be dynamic, using a planar projection centred on the viewer’s coordinates. It will embiggen all local geography while omitting distant lands. We’ll call this approach the Egocentric Cartographic Model.

Seems like a perfectly cromulent solution.

> Created by the cartographer Gerardus Mercator for navigation, the projection distorts continent sizes

AIUI the important word here is ‘nagivation’. If you use the other projections for navigation you’re going to have a bad time.

It depends. Some distort angles. Others distort distances. Some distort both, but only half as much. You can't have neither.
