The True Size of Countries (Mercator Map)
Drag countries on a Mercator world map to see how latitude changes their true scale in real time.
Move the comparison set
Drag any coloured country north or south. The map reports the projection's apparent scale at the new latitude.
No countries selected yet.
Try moving Greenland toward DR Congo to compare the contrast.

True Size Map Guide
Compare the real size of countries on an interactive world map
Drag countries across a Mercator map and compare their real geographic area while the tool reports latitude and projection scale.
How to use the true size map
- Choose one or more countries in the comparison set.
- Drag a colored country north or south on the map.
- Read the area, latitude, and Mercator scale factor.
- Reset positions whenever you want to return to the source geography.
Why Mercator maps distort country size
Mercator projection preserves local angles for navigation, but it cannot preserve area. Its scale increases with distance from the equator.

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.
Mercator is useful for navigation, but it does not preserve area. The country shapes and fixed area values remain unchanged as you move them.
