A world in scale

Every place people call home belongs to the same world. Seeing scale more clearly can make that shared map feel fairer.

Choose a country and the comparison animates, so the relationship feels immediate instead of abstract.

Share this part of the story

Share a clearer comparison when you want other people to see home the way you see it.

How this works · sources & limits

These are rounded reference total-area figures, including inland water, based on CIA World Factbook area listings. France means metropolitan France only. Africa uses the existing site’s 30,370,000 km² reference. Definitions and editions can differ; these are comparisons, not boundary determinations.

Circle radii scale by the square root of area, so circle areas — not diameters — are proportional. These are not country outlines or a geometric packing claim. The curated country list is not an exhaustive territorial inventory.

Inputs stay in this page’s memory; nothing is sent to a server or saved. Share only what you want others to see.
