Tools

True Size Comparison

Drag countries around a world map and compare their real sizes, free of Mercator distortion.

embeddable
Country Compare

Compare any two countries side by side — 44 World Bank / UNDP indicators (including urbanization, fertility, GDP growth, inflation, trade shares, health, education, the Human Development Index, military spending and renewables) plus surface area and derived density — with CSS ratio bars and shareable links.

embeddable
Country Distance

How far apart are two countries? Capital-to-capital great-circle distance in km and miles, with the centroid distance for comparison, a flight-time estimate, the share of Earth's circumference and a route mini-map.

embeddable
World Map Coloring

Color a blank world map to mark the countries you've visited, lived in, or want to explore — with travel stats, a legend, and free PNG/SVG export and share links.

embeddable
Metric Maps

Color-graded world maps for every indicator: 46 metrics — population, GDP per capita, life expectancy, CO₂ emissions, the Human Development Index and more — one choropleth page per metric with a full ranking table, free PNG/SVG export and an embeddable view.

Area Converter

Convert any area between km² and mi² and feel its real size — “≈ 2.3 × Beijing”, “43% of Central Park” — with analogy cards over a curated reference library of cities, landmarks, islands and regions.

embeddable
Time Zone Overlap

Find when two or three countries share working hours: overlap windows labeled in each side's local time (Beijing 08:00 ⇄ New York 19:00), a 24-hour strip per country, and the closest compromise when the working days never touch — DST computed live by the browser's Intl, never stored.

embeddable
Antipodes Finder

Pick a country and find its antipode — the exact point on the other side of the Earth. A world map pins the answer while the tool reports whether it falls on land (and in which country) or in the ocean, with the nearest coast and its distance.

Country Outline Quiz

Guess the country from its true-projection silhouette — free guessing from the full country list, and every wrong guess reveals the great-circle distance, a direction arrow and a proximity percentage. Five countries a game, six guesses each, silhouettes baked from Natural Earth boundaries at build time.
