Why Everyone Misplaces Africa

Ask a room of adults to sketch the world and the same map comes out: a huge Europe near the middle, a monstrous Greenland, and an Africa about the size of Mexico drifting somewhere warm. That map came from a wall poster, and the wall poster came from Gerardus Mercator, a 16th-century cartographer solving a navigation problem, not a truth problem. His projection keeps compass bearings straight, which sailors loved, and pays for it by inflating everything far from the equator.

What Mercator does to your head

On a Mercator map, Greenland looks roughly the size of Africa. In reality Africa is about fourteen times larger: 30.4 million square kilometres against Greenland's 2.2 million. The continent swallows the United States, China, India, Japan and most of Europe at once, with room to spare. Scandinavia looks like a subcontinent on the poster; it is smaller than Madagascar's neighbourhood. None of this is a fun fact for its own sake. If your inner Africa is a third of its true size, every place inside it is compressed toward its edges, and your pins land hundreds of kilometres toward the coasts and toward the north.

Miles Off plays on a globe partly for this reason: the sphere has no favourite latitude. But you bring the poster in your head to every round, so it helps to overwrite it deliberately.

The vertical truth

Africa is nearly symmetric about the equator: it reaches about 37°N in Tunisia and about 35°S at Cape Agulhas. That symmetry is the single most useful correction you can make. Cairo sits at 30°N, the latitude of New Orleans and Shanghai. Tunis, on Africa's north coast, is at 36.8°N, which is north of Tokyo. Meanwhile the distances are continental: Cairo to Cape Town is on the order of 7,000 kilometres, almost twice New York to Los Angeles. When the game asks for Kinshasa or Lusaka, most players pin far too high, because their inner Africa has been squashed from below.

Europe is further north than you think

The other half of the distortion is that Europe feels "middle" when it is actually high. London (51.5°N) is north of Calgary. Paris sits within half a degree of Vancouver. Madrid matches New York, Rome matches Chicago, Athens matches San Francisco. Berlin is north of every point in the contiguous United States. Europe lives at Canadian latitudes and gets away with it because the Gulf Stream keeps it unseasonably warm, which is a climate tell working in reverse.

Recalibrating, practically

• Re-anchor the equator. It crosses Africa through Gabon, the Congos, Uganda, Kenya and Somalia; in South America through Quito and the mouth of the Amazon; in Asia through Singapore's doorstep and Borneo. Say the list until it is boring.
• Pin the extremes. Dakar for Africa's westernmost bulge, the Horn for its easternmost, Tunis and Cape Agulhas for top and bottom. Four corners give the continent its true frame.
• Practise the pairs. Cairo–New Orleans, Tunis–Tokyo, London–Calgary, Madrid–New York. Latitude pairs are cheap to memorize and transfer to every neighbouring city.
• When in doubt, go lower and bigger. For interior African places, bias your pin toward the equator and away from the coasts. The continent has more middle than your instincts believe.

The reveal arc will tell you how it is going; the Hardest Places chart suggests it is going badly for almost everyone, which is excellent news for anyone who fixes it.
