Question 1

What is the True World Map / The True Size of countries?

Accepted Answer

True World Map (trueworldmap.com) is an interactive cartographic comparison tool that displays the true relative sizes of countries, continents, and islands. Standard flat world maps rely on the 1569 Mercator projection, which severely exaggerates polar landmasses. True World Map allows you to select and drag any nation across latitudes and watch its boundary reproject dynamically using geodesic spherical geometry to reveal its actual physical land area.

Question 2

Why is the standard Mercator world map distorted?

Accepted Answer

The Mercator projection was invented in 1569 by Gerardus Mercator specifically for maritime navigation. On a Mercator map, lines of constant compass bearing (rhumb lines) are straight lines. Because Earth is spherical, lines of longitude naturally converge at the poles; however, a cylindrical Mercator projection forces longitude lines to remain parallel. To preserve correct local angles and shapes (conformality), the map must stretch north-south distances by the secant of the latitude, inflating polar landmasses by sec²(latitude) in land area.

Question 3

What is the true size of Africa compared to Greenland?

Accepted Answer

In reality, Africa encompasses 30,370,000 square kilometers (11,725,000 square miles), making it approximately 14 times larger than Greenland (2,166,086 square kilometers / 836,330 square miles). On a conventional Mercator map, Greenland appears equal in size or larger than the entire African continent because Greenland is centered around 72° North latitude where area distortion reaches approximately 10.5×.

Question 4

How big is Russia compared to Africa?

Accepted Answer

On standard classroom Mercator maps, Russia appears twice the size of Africa. In reality, Africa (30.37 million km²) is nearly double the land area of Russia (17.10 million km²). When Russia is moved down to the equator on our interactive map, it easily fits inside Africa with over 13 million square kilometers of land to spare.

Question 5

Why do digital mapping services like Google Maps and OpenStreetMap use Web Mercator?

Accepted Answer

Web mapping platforms standardized on Web Mercator (EPSG:3857) because it maps the world into a perfect 256x256 pixel square at zoom level 0. This enables seamless quadtree tile slicing at every zoom level. Additionally, Mercator is conformal, meaning road intersections and street corners remain true 90-degree right angles at local city levels.

Question 6

What are equal-area map alternatives like Equal Earth and AuthaGraph?

Accepted Answer

Equal-area map projections preserve accurate relative land areas. The Equal Earth projection, developed in 2018 by Tom Patterson, Bojan Šavrič, and Bernhard Jenny, is officially adopted by the United Nations and displays all continent proportions accurately. The AuthaGraph, invented by Hajime Narukawa, unfolds a 96-triangle tetrahedron to produce a seamless 2D flat map that preserves both proportional area and continent shapes.

Question 7

How big is Australia compared to Europe or the United States?

Accepted Answer

Australia spans 7,692,024 square kilometers (2,969,907 square miles). When placed over Europe, Australia stretches all the way from the Atlantic coast of Spain to Eastern Poland, and from Scandinavia down to the Mediterranean. It is roughly the same geographic footprint as the contiguous United States (excluding Alaska).

Question 8

Which country experiences the greatest Mercator projection enlargement?

Accepted Answer

High-latitude northern nations experience the greatest visual distortion. Greenland is inflated by over 1,000% (10.5× area distortion at 72°N). Northern Canada (Ellesmere Island at 80°N) is inflated by over 3,300% (33× area distortion), and Svalbard (Norway at 78°N) is inflated by over 2,300% (23× area distortion).
