True Size of Countries

The true size of a country is its real surface area in square kilometres, measured on the curved surface of the Earth. World maps based on the Mercator projection distort this by stretching land near the poles. Our true size of countries tool lets you pick any two countries (or continents) and see them drawn at exactly the same scale — with a plain-English answer telling you which is bigger and by how much.

The best way to compare country sizes is to draw both countries at the same equal-area scale and compare their real surface area in km². This page does both: it renders the selected countries with matching visual-area scaling and shows the exact country size comparison underneath.

It is a real size comparison map rather than a single world map projection. Instead of showing every country at once, it lets you pick two countries or continents and renders them at equal scale, which is the clearest way to see their actual size without Mercator distortion.

For country comparisons, true size, real size and actual size all refer to the same idea: the real surface area of a country on Earth, usually measured in square kilometres. The phrases differ because people search for the concept in different ways.

Mercator stretches the world vertically more and more as you approach the poles. At Greenland's centroid (about 72°N), the area scale factor is roughly ten — meaning the Mercator map shows Greenland about ten times larger than it really is. That's why Greenland looks comparable to Africa on most world maps, even though Africa is fourteen times bigger.

Yes. Greenland is about 2.16 million km², while Africa is about 30.4 million km². You could fit roughly fourteen Greenlands inside the African continent. The illusion that they are similar in size comes entirely from the Mercator projection.

Mercator is a cylindrical map projection invented by Gerardus Mercator in 1569. It preserves angles and shapes locally — which is why it's still the default for navigation and digital maps like Google Maps and OpenStreetMap. The trade-off is that it badly distorts area, especially near the poles. Our true size of countries tool reveals exactly how much.

Equal-area projections such as Gall–Peters, Mollweide, Hammer, and Equal Earth all preserve area and show the true size of countries. They distort shape instead. The Robinson projection is a popular compromise. This tool uses an equal-area projection (Equal Earth) under the hood when it draws two countries side-by-side — so the visual sizes you see are honest.

Country borders are stored as latitude/longitude polygons from the open Natural Earth dataset. We compute each country's real area on the spherical Earth using standard spherical-geometry math, which gives a true surface-area number in km². When you compare two countries, we render both shapes using the same equal-area projection at the same scale — so their visual sizes honestly reflect the real ratio.

Russia's centroid sits around 61°N — high enough that Mercator inflates its area by roughly four times. The USA's centroid is near 38°N, where the distortion is only about 1.6×. So Mercator inflates Russia much more than the USA, making the size gap look enormous. In reality Russia is only about 1.7 times the size of the USA, not five times.

No. Mercator can't even draw Antarctica properly — most maps clip it as an infinite stretched band. Antarctica is about 14.2 million km² — bigger than the United States but smaller than Russia. On a true size of countries comparison, Antarctica fits between the USA and Russia in area, not above all of them.

Yes. The whole tool is mobile-first. The two pickers stack cleanly on small screens, the visual comparison resizes to fit your viewport, and one-tap preset buttons load iconic comparisons like Greenland vs Africa or Russia vs USA without any typing.

Areas are computed from open Natural Earth country boundaries on the WGS-84 spheroid using standard spherical-geometry math, giving a true surface-area number in km² that matches published country areas to within a fraction of a percent. The Mercator distortion factors in the Top 10 table are computed using sec²(latitude), the standard formula for Mercator area distortion.
