Gall-Peters Projection

I saw this map for the first time yesterday and stared at it for about 10 minutes. The Gall-Peters projection shows land masses in their true proportion and has 90 degree lat-log interceptions.

I'm accustomed to looking at a Mollweide projection (lower). I bet you didn't picture Germany being that far north. I didn't. I think I need to go back to grade two.

Actually, there are a great many 'equal area' map projections out there, and Gall-Peters is not one of the better ones. It distorts the polar areas east-west, as well having some long stretching. No cylindrical map projection can do a good job representing the whole Earth, hence the more 'realistic' Mollweide projection (also equal area)

There are some 200+ projections in regularly published collections, although many fewer in regular use. You cannot display the Earth on a plane map without distortion; you can only select the distortions you want to show.
