Mercator Misconceptions: Clever Map Shows the True Size of Countries
This Clever Map Shows the True Size of Countries
Maps are hugely important tools in our everyday life, whether it’s guiding our journeys from point A to B, or shaping our big picture perceptions about geopolitics and the environment.
For many people, the Earth as they know it is heavily informed by the Mercator projection—a tool used for nautical navigation that eventually became the world’s most widely recognized map.
Mercator’s Rise to the Top
With any map projection style, the big challenge lies in depicting a spherical object as a 2D graphic. There are various trade-offs with any map style, and those trade-offs can vary depending on how the map is meant to be used.
In 1569, the great cartographer, Gerardus Mercator, created a revolutionary new map based on a cylindrical projection. The new map was well-suited to nautical navigation since every line on the sphere is a constant course, or loxodrome.
Geographic Inflation
The vast majority of us aren’t using paper maps to chart our course across the ocean anymore, so critics of the Mercator projection argue that the continued use of this style of map gives users a warped sense of the true size of countries—particularly in the case of the African continent.
Mercator’s map inadvertently also pumps up the sizes of Europe and North America. Visually speaking, Canada and Russia appear to take up approximately 25% of the Earth’s surface, when in reality they occupy a mere 5%.
As the animated GIF below—created by Reddit user, neilrkaye – demonstrates, northern nations such as Canada and Russia have been artificially “pumped up” in the minds of many people around the world.
Greenland, which appears as a massive icy landmass in Mercator projection, shrinks way down. The continent of Africa takes a much more prominent position in this new, correctly-scaled map.
This visualization also highlights how distorted neighboring countries can look in Mercator projection. In the GIF above, Scandinavian countries no longer loom imposingly over their European neighbors, and Canada deflates to a size similar to the United States.
Despite inaccurate visual features—or perhaps because of them—the Mercator projection has achieved widespread adoption around the world. This includes in the classroom, where young minds are first learning about geography and forming opinions on the relationships between countries.
Getting Reacquainted with Globes
Google, whose map app is used by approximately 150 million people per month, took the bold step of using different projections for different purposes in 2018.
The Earth is depicted as a globe at further zoom levels, sidestepping map projection issues completely and displaying the world as it actually is: round. The result is a more accurate depiction of countries and landmasses.
With 3D Globe Mode on Google Maps desktop, Greenland's projection is no longer the size of Africa.

At closer zoom levels, users are typically using maps for things like navigation, which the Mercator projection was designed for. The exact angles of roads and borders are preserved in this projection.
In the Right Direction
In a more globally connected world, geographic literacy is more important than ever. As people become more accustomed to equal area maps and seeing the Earth in its spherical form, misconceptions about the size of continents may become a thing of the past.

Visualizing the Most Common Pets in the U.S.
Lions, tigers, and bears, oh my!—these animals do not feature on this list of popular American household pets.
Visualizing The Most Common Pets in the U.S.
This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.
In this graphic, we visualized the most common American household pets, based on 2023-2024 data from the American Pet Products Association (accessed via Forbes Advisor).
Figures represent the number of households that own each pet type, rather than the actual number of each animal. The “small animal” category includes hamsters, gerbils, rabbits, guinea pigs, chinchillas, mice, rats, and ferrets.
What is the Most Popular American Household Pet?
Based on this data, dogs—one of the first domesticated animals—are the most common pets in the United States. In fact, around 65 million households own a dog, and spend an average of $900 a year on their care.
Rank | Species | Households |
---|---|---|
1 | 🐶 Dog | 65M |
2 | 🐱 Cat | 47M |
3 | 🐟 Freshwater Fish | 11M |
4 | 🐰 Small Animals | 7M |
5 | 🐦 Bird | 6M |
6 | 🦎 Reptile | 6M |
7 | 🐴 Horse | 2M |
8 | 🐠 Saltwater Fish | 2M |
Note: Households can own multiple pets, and are counted for all relevant categories.
Cats rank second, at 47 million households, and these smaller felines are a little less expensive to own at $700/year according to Forbes estimates.
But aside from these two juggernauts, there are plenty of other common pet types found in households across the country.
Freshwater fish can be found in 11 million households, along with small animals—rabbits, hamsters, guinea pigs—in 7 million. Meanwhile, nearly 6 million homes have birds or reptiles.
Pet Ownership is on the Rise in America
Forbes found that 66% of all American households (numbering 87 million) own at least one pet, up from 56% in 1988. One third of these (29 million) own multiple pets.
A combination of factors is driving this increase: rising incomes, delayed childbirth, and of course the impact of the pandemic which nearly cleared out animal shelters across the globe.
America’s loneliness epidemic may also be a factor. Fledgling research has shown that single-individual households with pets recorded lower rates of loneliness during the pandemic than those without a pet.
