Compare Map Projections

Last Update: Aug 16, 2016 (see below)

Note: English is not my native language. Probably there’ll be a lot of mistakes here. Sorry!


This site ist about map projections, specifically about world map projections.
A map projection is needed to show the spherical surface of the earth on a flat map (see What’s a Map Projection?).
There is some info about projections (see below), but more importantly, it’s about their appearance: Out of more than 100 different map projections you can select two at a time to view their differences and similarities in a direct comparison.


Sometimes, two map projections might look so similar that it’s hard to tell the difference.
Sometimes, you might see the difference but want to study it more closely.
Maybe you want to compare the distortions which are present in each and every map projection.
Or maybe you dont’t want to compare map projections but rather browse a bunch of nice projection images.
You can do all of that here on this website.

For more detailed information about the spirit and purpose of this website, read What’s this all about?


To select thw two projections you’d like to compare, you’ve got four options:

  1. In the Selection Form you can choose two projections from the menus;
  2. in the List of projections you can see the names of and some basic information about the provided projections – again, you can choose two of them to compare (at the time being, this might not work on small screens);
  3. in the Selection via Thumbnail you can pick the desired projections… well, from a list of thumnails;
  4. and the Suggested Pairings provide a list of projections, always in twos, being (in my opinion) recommonable pairings.

If you’re not familiar with map projection names, options no. 3 and 4 might be the best for you.

And then?

Die two projections you’ve chosen will be compared in three (simple mode) resp. eight (expert mode) different ways.
Sometimes you’ll see only one projection image at first and you’ll have to click it to switch to the second projection. Sometimes the images will be layered on top of each other semi-transparently.

I’m confused by these different kinds of comparison!

Read the short hints!
In case you never heard of Tissot’s indicatrix (which is part of the comparisons) read the article that explains it.

Single View

If you don’t want to compare but rather view the projections individually, head over to the Single View Section.
Maybe you want to share an image of you favorite map projection via email or social networks? – Okay, this can be done in the Single View section!

Are there any informations about map projections here?

In case you came here in search of informations about map projections – well, yeah, some basics are provided here:

Nonetheless, I highly recommend the site that are listed in the Links section! They are more extensive, more precise and better written than my own articles.

To be honest, this is a bit of a »quick & dirty« update – for nearly five months, nothing has happened here, so I was in a rush to get the stuff online at last. So in case you’ll find any typos more typos than usual in the new article; in case something shouldn’t work… fear not! In the days and weeks to come, I’ll take care of it.
