Compare country outlines on a map that corrects Mercator distortion.

TrueSize is an interactive map for checking how large countries and regions are relative to one another when projection distortion is removed. Users can search for places, place them on the map, and compare their apparent footprint across latitudes using map or globe views.

Why it stands out

  • Focuses specifically on the common Mercator-size misconception rather than general map browsing.
  • Supports both country and region comparisons, not just sovereign states.
  • Includes a globe view alongside the flat map for projection-aware exploration.
  • Offers broad language support for an educational visualization tool.

Good to know

  • Small-screen use may require portrait orientation; the site warns that landscape leaves too little vertical space.
  • It is mainly a visual comparison tool, not a full GIS platform for precise measurement or spatial analysis.
  • The comparison depends on simplified outlines, so it should not replace authoritative boundary or area datasets.

Under the radar: Press K to jump straight to search instead of opening it with the mouse.
