Mercator keeps directions useful, but stretches land near the poles.
Mercator makes Greenland look close to Africa in size because Greenland sits far north, where the projection stretches land dramatically. In reality, Africa covers about 30.4 million km², roughly fourteen times Greenland’s 2.2 million km².
Russia spans high northern latitudes, so Mercator exaggerates much of its outline. Its real area is about 17.1 million km² compared with roughly 9.8 million km² for the United States, making Russia about 1.7 times larger, not overwhelmingly bigger.
Mercator paints Antarctica as an endless white band wider than Africa, Asia and Australia combined. Released from its polar prison and measured honestly, Antarctica is only about 44 percent larger than the United States, not the planet-sized continent the map suggests.
A standard Mercator world map enlarges places near the poles.This equal-area country size comparison keeps every selected shape on one shared scale, so you can compare the actual size of countries and continents without the familiar map distortion.
Mercator was built for navigation, not for comparing the real size of countries.
A navigation breakthrough
In 1569, the Flemish cartographer Gerardus Mercator published a world map for navigation. Its key advantage was that a constant compass bearing could be drawn as a straight line. Achieving that required stretching the map more and more towards the poles.
That design was brilliant for sailors, but misleading for comparing land area. Places at high latitudes, including Greenland, Canada and Russia, appear far larger relative to tropical regions than they are on the globe.
The distortion formula
On a spherical Mercator map, the local area scale factor is sec²(latitude). It is 1 at the equator, 4 at 60° north or south, and about 10.5 at 72°. Distortion varies across a country because a country covers a range of latitudes.
The poles cannot be shown because the scale tends towards infinity. Web Mercator remains practical for zoomable maps, but not for honestly comparing country area.
This interactive country size comparison tool answers how big countries really are. Unlike a standard world map, it compares every selected shape using mathematically verified equal-area scaling.
A true size map displays countries with area-preserving geometry instead of enlarging places near the poles. Use the comparison tool above to place two country or continent shapes on the same honest visual scale.
A country’s real size is its surface area on the curved Earth, measured here in square kilometres. The coral and blue shapes are normalised so their visible areas match the real-world ratio.
Choose any two available countries or continents for an instant country size comparison. The result gives both areas and states exactly how many times larger one place is than the other.
From true size to real travel
See how countries really compare, then save the places that inspire you and turn every journey into maps, stats, stamps and TripBooks.
Pick any two places and the tool draws them at the same scale, with a plain-English answer telling you which one is bigger and by how much.
Tap the first picker and search the available countries, territories and continent groupings.
Tap the second picker. Both places appear side by side on the same canvas.
Both shapes are drawn at the same visual scale, so the size difference reflects their real area ratio.
Swap the two places or search again to compare examples such as Greenland and Africa, Russia and the USA, or Australia and Europe.
These frequently searched real country size comparisons use the same rounded areas shown by the tool. Choose the pair above to inspect their outlines at one equal scale.
Africa is about fourteen times larger than Greenland: 30.4 million km² compared with 2.2 million km².
Russia is about 1.7 times the size of the United States: roughly 17.1 million km² versus 9.8 million km².
Antarctica is about 1.4 times larger than the United States, not the endless continent suggested by a Mercator map.
South America is about 1.75 times larger than Europe: approximately 17.8 million km² compared with 10.2 million km².
Europe is about 1.3 times larger than Australia by area, although their familiar map shapes can suggest a different balance.
Brazil is about 1.1 times larger than Australia, making this one of the closest popular country size comparisons.

USGS Professional Paper 1395EPSG identifies WGS 84 / Pseudo-Mercator, commonly called Web Mercator, as a projected coordinate reference system for web mapping and visualisation. Google Maps and Apple MapKit document Mercator-based coordinates, while standard OpenStreetMap tiles use EPSG:3857.
EPSG:3857 official registry entryGoogle documents that Maps world coordinates use the Mercator projection and clip the otherwise infinite map near 85° latitude. Apple MapKit and OpenStreetMap tile documentation describe the same broad web-mapping convention.

Choose two places to compare their real land area at the same visual scale.
It means the country’s real surface area on the curved Earth, usually measured in square kilometres. A true-size comparison removes the visual inflation created by common flat world maps.
For country comparisons, true size, real size and actual size describe the same measurement: surface area on Earth, normally stated in square kilometres. The different phrases refer to the same goal of comparing places without Mercator area distortion.
It is an equal-scale comparison map rather than one flat map of the whole world. Showing two selected outlines together makes their real area ratio easier to judge without introducing the area distortion of a Mercator world map.
Mercator maps preserve direction for navigation, but stretch land more as it approaches the poles. That makes Greenland, Canada and Russia look much larger than they really are.
Both country shapes use an equal-area projection and one shared visual scale. Their displayed areas therefore remain proportional to their real surface areas.
Yes. Greenland covers about 2.2 million km² and Africa about 30.4 million km², so Africa is roughly fourteen times larger. Mercator distortion makes them appear far closer in size.
Greenland lies at high northern latitudes, where the Mercator projection enlarges area dramatically. Its real area is about 2.2 million km², compared with Africa’s 30.4 million km².
Equal-area projections such as Equal Earth, Gall-Peters and Mollweide preserve relative area. Every flat projection changes something, but equal-area maps are the right choice for comparing country size.
Yes. The searchable dataset includes countries, territories and seven continent groupings, so comparisons such as Greenland versus Africa work instantly.
Country geometry comes from Natural Earth through the world-atlas dataset. Country areas are calculated from that spherical geometry, while the displayed continent totals use published reference areas cited in the methodology section.
Yes. The comparison tool is free and designed for phones, tablets and desktop browsers, with responsive country pickers and an equal-scale visual that adapts to the screen.
Yes. The country and continent comparison tool is free to use on mobile and desktop, with no account required.
Mercator preserves local angles and compass directions, which made it useful for navigation. It remains familiar and practical for some maps, but it is not suitable for comparing the relative area of countries.
Every flat map projection distorts something. Equal-area projections preserve relative size, so shapes may look less familiar while the amount of area shown remains honest.
