The Country Area Comparison tool lets you visualize and compare the physical size of any countries side by side. Select up to 10 countries, toggle between km² and mi², and see instant percentage comparisons showing how each nation's area relates to the others.

How to Use the Country Area Comparison Tool
The Country Area Comparison makes it easy to put geographic size into perspective. When geography lessons or news articles describe a country's size in square kilometers, it's hard to mentally visualize it. This tool creates an instant visual reference.
Step 1: Add Countries
The tool starts with the top 5 largest countries: Russia (17.1M km²), Canada (9.98M km²), United States (9.83M km²), China (9.6M km²), and Brazil (8.5M km²). Type any country name in the search box to add more countries to the comparison. The autocomplete suggests matches as you type.
Step 2: Read the Bar Chart
The horizontal bar chart shows each country's area proportionally. The longest bar is always the largest country in your selection. Hover over any bar to see the exact area value. Adding a small country like Switzerland (41,285 km²) next to Russia creates a striking visual contrast — Switzerland's bar is barely visible at 0.24% of Russia's area.
Step 3: Toggle km² / mi²
Switch between square kilometers and square miles with the toggle. For American audiences, mi² is the more intuitive unit. The United States at 9,833,517 km² is also 3,796,742 mi². Australia at 7,692,024 km² is 2,969,907 mi² — slightly smaller than the contiguous US but larger when Alaska is included.
Step 4: Compare Population Density
The comparison table shows population density alongside area, which reveals surprising patterns. Bangladesh (147,570 km²) has a population density of over 1,170 people per km², while neighboring Mongolia (1.56M km²) has just 2 people per km² — making Mongolia one of the world's least densely populated countries despite being larger than France, Spain, Germany, Italy, and Poland combined.
FAQ
How many countries can I compare?
You can add up to 10 countries at a time for comparison. The default view shows the top 5 countries by area: Russia, Canada, United States, China, and Brazil.
Is this tool free?
Yes, the Country Area Comparison is completely free with no signup required. The chart and all calculations run locally in your browser.
Is the area data accurate?
Area data is based on official total area figures including inland water bodies. The data matches standard geographic sources and is accurate to within published national statistics.
How do I switch between km² and mi²?
Use the unit toggle at the top. Switching to mi² updates both the chart labels and the comparison table. Russia, for example, spans 17,098,242 km² or 6,601,668 mi².
How is population density calculated?
Population density is calculated as total population divided by total area (in km² or mi² depending on your unit selection). Higher density countries like Bangladesh (1,265/km²) contrast sharply with Mongolia (2/km²).
Can I remove a country from the comparison?
Yes, click the × button next to any country name to remove it from the comparison. The chart and table update instantly. You must keep at least 1 country selected.
What does the percentage comparison mean?
The percentage comparison shows how large each country is relative to the largest country in your current selection. For example, if Russia is the largest, Canada at 9,984,670 km² would show '58.4% the size of Russia'.
