Africa isn’t small at all. It’s the world’s second-largest continent, covering 30.37 million square kilometers, roughly 20% of Earth’s entire land area. The reason it looks small on most maps comes down to a 450-year-old cartographic choice that warps the size of every landmass depending on how far it sits from the equator.
How the Mercator Projection Shrinks Africa
The map you’ve probably seen most often, whether on a classroom wall, in a textbook, or on Google Maps, is based on the Mercator projection. Created in 1569 by Dutch cartographer Gerard Mercator, it was designed for a very specific purpose: helping sailors navigate the ocean. It allowed mariners to draw a straight line between two ports, follow a constant compass bearing, and arrive where they intended. For that job, it worked brilliantly.
The tradeoff is severe. Flattening a sphere into a rectangle requires stretching the surface, and the Mercator projection stretches landmasses more and more as they get farther from the equator. Countries near the poles balloon in size while countries near the equator stay close to their true proportions, or even appear to shrink relative to everything around them. Africa sits almost entirely within the tropics, straddling the equator. Canada, Russia, Greenland, and Scandinavia sit near the top of the map, where distortion is greatest, so they look enormous by comparison.
The result is a map where Greenland and Africa appear roughly the same size. In reality, Africa is 14 times larger. Greenland covers about 0.8 million square miles. Africa covers 11.7 million.
How Big Africa Actually Is
The numbers are staggering once you see them laid out. You could fit the United States, China, India, Japan, Mexico, and most of Europe inside Africa’s borders simultaneously, and still have room left over. The U.S. alone accounts for only about 32% of Africa’s land area. China covers roughly 31.6%. India adds another 10.8%. Stack all of those countries together and they still don’t match Africa’s total footprint. The continent is home to 54 countries and 1.2 billion people.
Interactive tools like “The True Size Of” let you drag country outlines across different latitudes on a Mercator map, watching them grow or shrink as they move. Dragging Greenland toward the equator, for instance, reveals how dramatically the projection inflates it. Dragging Russia into Africa’s latitude shows that Russia, which dominates the top of most world maps, could fit inside the continent.
Why This Distortion Matters
The Mercator projection was appropriate for navigation from 1569 through about 1700. But it was never designed to be the default map for classrooms, news broadcasts, or atlases. No projection was ever specifically designated as ideal for general reference maps, yet Mercator became the standard anyway, largely through habit and convenience.
Psychologists point out that humans innately equate size with importance. When the countries that appear largest on a map are overwhelmingly in Europe and North America, and when Africa and South America are visually minimized, the effect on perception is real even if unintentional. The countries inflated by the Mercator projection tend to be wealthier nations in the global north, while the countries that get shrunk are disproportionately in the developing world. Critics argue this visual imbalance reinforces a worldview where European and North American nations seem naturally dominant, while equatorial regions seem peripheral.
Research from the University of Michigan notes that this map has likely had a subconscious impact on how people understand global power and geography. Students who grow up seeing Africa as roughly the same size as Greenland absorb that impression without questioning it. The distortion becomes invisible precisely because it’s everywhere.
Schools Are Starting to Switch
In 2017, Boston’s public school system began phasing in a different map for its classrooms: the Gall-Peters projection. Unlike Mercator, the Gall-Peters projection preserves the relative area of landmasses. Africa appears much larger compared with Europe and North America, reflecting its true scale. The tradeoff is that shapes get distorted instead. Countries near the equator look stretched vertically, and those near the poles look compressed. It’s not a perfect map (no flat map of a round planet can be), but it corrects the size problem that Mercator makes worse.
The reaction from students was telling. Teachers reported kids saying “Wow” and “No, really? Look at Africa, it’s bigger” when they saw the Peters map for the first time. Boston’s assistant superintendent called the switch part of a three-year effort to decolonize the curriculum across the district’s 125 schools and 57,000 students, 86% of whom are non-white. The district didn’t remove Mercator maps entirely but committed to purchasing only Peters projection maps going forward.
No Flat Map Gets It Perfectly Right
Every map projection involves compromise. You can preserve accurate shapes, or you can preserve accurate sizes, but you cannot do both on a flat surface. The Mercator projection prioritizes shape and navigational angles. The Gall-Peters projection prioritizes area. Other projections, like the Robinson and Winkel Tripel (used by National Geographic), try to split the difference, accepting moderate distortion in both shape and size to produce something that looks more balanced overall.
The core issue isn’t that one projection is “wrong.” It’s that most people encounter only the Mercator projection and never learn about the distortion baked into it. Once you understand that the familiar world map inflates northern landmasses and compresses equatorial ones, Africa’s true size clicks into place: a continent large enough to swallow the U.S. and China together, with room to spare.
