About Equal Earth Lab
Equal Earth Lab is an independent project for people who want to understand what world maps preserve, what they change, and how to make useful comparisons.
What the project does
The world map lets you inspect country outlines, switch projections and move a copy of a country to see how its appearance changes. The selected comparisons connect that visual experiment with area figures calculated from a consistent geographic model. Articles explain the decisions behind those results, and the map maker creates a map you can use in a document or presentation.
The first edition is in English and offers Equal Earth, Robinson and Mercator. The maps use real geographic data; illustrations are generated from those data and the stated projection equations. They are not generated pictures of invented geography.
Independent of the projection’s creators
Equal Earth was designed by Bojan Šavrič, Tom Patterson and Bernhard Jenny in 2018, as documented in the projection reference. They created the projection; this website explains and implements it. Equal Earth Lab does not claim to be their official website or to speak for them.
The project is also independent of Natural Earth, the United Nations, the African Union and the software projects cited in our sources. A citation identifies the source of a claim or dataset. It does not imply endorsement.
What makes a comparison useful
An area ratio is meaningful only when the two sides use compatible definitions. Our figures are boundary-model estimates, measured on a 6,371 km sphere. They are not presented as official national land-area statistics. Island scope, geographic partitions and generalized coastlines are explained in the methodology.
The prose is drafted with AI assistance and published under the project name. We distinguish mathematical calculations, source-based facts and editorial advice. The editorial policy describes how revisions and corrections should be handled. No fictional author biography or external-review claim is used.
