The United States (blue) and Denmark (orange), both drawn at their true size and the same scale. Islands and territories far from the main land are left out of the drawing; the area figures include them.

How many times does it fit?

Denmark would fit into the United States about 217 times. The number counts area, not shape: on a real map the smaller one would have to be cut up to fill the bigger one exactly.

Which has more people?

Denmark has 5.8 million people, the United States has 326.7 million people. Denmark is more crowded: about 134 people share each square kilometre, against 35 in the United States.

Why do maps get sizes wrong?

Most world maps on walls and in apps use the Mercator projection. It keeps shapes and directions right, which is why sailors loved it, but it stretches everything the further it is from the equator. Greenland looks as big as Africa on such a map, even though Africa is about fourteen times bigger. Denmark lies further from the equator than the United States, so on a wall map it looks bigger than it really is.

The drawing on this page uses an equal-area projection centred on each place, so the two shapes can be compared fairly.

How big is a square kilometre?

A square kilometre (km²) is a square that measures one kilometre on each side. About 140 football pitches fit into it. So a country of 40 000 km² is as big as 40 000 such squares put together – that is more than five million football pitches.
