Frequently asked questions
How does the country size comparison work?
Each country is drawn with an equal-area projection centred on itself and both use the same scale, so the outlines show true relative size, free of the Mercator stretch that makes Canada or Russia look enormous on most web maps.
Is the UK bigger than ...?
The United Kingdom is about 242,500 km². That is a little smaller than Ghana or Romania, and about the size of the US state of Oregon (255,000 km²). Try it above.
Why do sources give different areas for the same country?
Some include inland water, lakes and coastal waters and some don't, and some count disputed territory. This tool uses total area from the mledoze/countries dataset.
