Discover why your world map has been lying to you and how we reveal the truth

Why Do Maps Lie About Size?

The Mercator projection, used by most online maps including Google Maps, was created by Gerardus Mercator in 1569. It was designed for one specific purpose: navigation at sea.

While the Mercator projection brilliantly preserves angles and directions (making it perfect for sailing), it comes with a massive trade-off: it dramatically distorts the size of landmasses, especially as you move away from the equator.

The Result?

  • β€’ Greenland appears the size of Africa (it's actually 14Γ— smaller)
  • β€’ Alaska looks larger than Mexico (Mexico is actually bigger)
  • β€’ Europe seems comparable to South America (it's less than half the size)
  • β€’ Antarctica appears as the largest continent (it's actually 5th largest)

The Mathematics of Distortion

The Mercator projection stretches the Earth like pulling taffy. The distortion increases exponentially as you move toward the poles. Here's the shocking math:

Distortion by Latitude

Equator (0Β°)No distortion
30Β° North/South15% larger
45Β° North/South41% larger
60Β° North/South100% larger
70Β° North/South192% larger
80Β° North/South475% larger

How to Use TrueCountrySizes

πŸ”

1. Search & Add Countries

Type any country name in the search box. Our intelligent search finds countries, continents, and even U.S. states. Click to add them to the map at their true geographic location.

βœ‹

2. Drag to Compare

Click and drag countries anywhere on the map. Watch them dynamically resize based on latitude. The further from the equator, the more dramatic the size change!

Why This Matters

πŸŽ“ Educational Impact

Map projections shape our worldview. When we see Greenland as large as Africa, or Europe as comparable to South America, it affects our understanding of global geography, politics, and economics. Accurate size perception helps us better understand our planet.

🌍 Global Perspective

The Mercator projection tends to exaggerate the size of developed nations in the Northern Hemisphere while minimizing regions near the equator. Understanding true sizes helps combat geographic bias and promotes a more accurate global perspective.

🧭 Better Decision Making

From understanding climate patterns to appreciating biodiversity, from planning travel to analyzing global trade, accurate geographic knowledge leads to better informed decisions in both personal and professional contexts.
