How to use the true size map
- Choose one or more countries in the comparison set.
- Drag a colored country shape north or south on the map.
- Read the area, latitude, and Mercator scale factor.
- Compare places such as Greenland, Russia, Canada, Brazil, India, and the United States.
Why Mercator maps distort country size
Mercator projection is useful for navigation because it preserves local angles, but it cannot preserve true area on a flat map. Distance from the equator increases the scale factor, so countries near the poles look much larger than they really are.

FAQ
What is a true size of countries map?
A true size of countries map lets you move countries across latitudes so you can compare their real geographic area without being misled by Mercator projection distortion.
Why do countries look different sizes on a Mercator map?
Mercator projection preserves local shape for navigation, but it stretches land near the poles. Countries such as Greenland, Canada, and Russia appear larger than their real area.
How do I compare real country sizes with this tool?
Choose countries from the comparison set, drag the colored shapes on the map, and watch the scale factor update as each country moves to a new latitude.
Does the tool compare countries by real area?
Yes. The tool shows country area and uses Mercator scale math to demonstrate how apparent size changes when a country is moved north or south.
