TrueSize: Compare Countries

Explore the true size of countries, continents, and regions with TrueSize app. Move territories around an interactive map and compare their real proportions without the size distortion of traditional flat maps.

Key Features

• True-size comparisons

Compare countries and regions using spherical geometry, without the size distortion caused by flat map projections.

• 750,000+ geographic regions

Explore countries, territories, states, provinces, historical borders, islands, and more.

• Historical timeline

Play through history or jump to any year, BC or AD, and watch borders, names, and flags change on the map.

• Divide and merge

Split any country into its states or provinces with one tap, then merge the pieces into your own shapes.

• Population tool

Draw a circle anywhere on the map and see roughly how many people live inside it, shown as 3D columns, along with the population density.

• Languages and language families

See the approximate areas where languages and language families are spoken, then move and compare them like any other region.

• Natural features

Explore mountains, peaks, deserts, islands, peninsulas, archipelagos, seas, bays, lakes, rivers, river basins, all 52 tectonic plates, and famous roads.

• Geography games

Play the TrueSize Challenge to guess the larger territory, test your knowledge with the Flag Quiz, or try Split the People: draw one line that divides a place's population in half.

• Measurement tools

Measure true geodesic distances in kilometers or miles, check compass bearings, and draw custom shapes.

• Edit any boundary shape

Modify the vertices of countries, regions, and other map shapes directly on the map. Add, move, select, or delete points with Undo and Redo support.

• Facts and geographic details

View population, area, flags, and useful facts for regions you explore.

• Import & edit GeoJSON / TopoJSON files

Load your own map data, modify shapes, simplify or merge boundaries, and export your changes. Ideal for students, educators, and GIS enthusiasts.

• Share your discoveries

Create and share interactive map comparisons with others.

Why TrueSize?

Traditional flat maps can significantly distort the apparent size of countries and regions, especially near the poles. TrueSize uses spherical geometry to provide more realistic size comparisons while letting you freely move and explore territories around the globe.

From the creators of TrueSize.net, the official TrueSize app brings interactive geography tools, hundreds of thousands of regions, a historical timeline, population and language maps, games, measurements, and custom geographic data to your device.

Rediscover the world as it truly appears – clearly, accurately, and interactively.
