What's the biggest country?

"Biggest" seems like the one geography superlative that shouldn't need a definition. But depending on whether you count water, and how much of the land is actually farmable, the ranking changes twice — and Canada, the textbook #2, ends up nowhere near the top.

Total area (including inland water) Land area (water excluded) Arable land
Total area, land area, and arable land for the six largest countries by total area Russia, Canada, the United States, China, Brazil, and Australia ranked by total area, with every bar drawn to the same scale so bar length matches real area; a tick marks each country's land area and a teal bar its arable land. Canada ranks 2nd by total area but falls to 6th in the world by arable land; the United States rises to 1st by arable land despite ranking 3rd by total area.

Canada is the world's 2nd-biggest country by total area, and only the 6th-biggest by farmable land. About 9% of its area is fresh water, which drops it to 4th by land alone, and only about 4.3% of its land is arable. The United States, with over 16% of its land arable, has the most farmland of any country, roughly tied with India.

Every ranking of "biggest" answers a narrower question than it seems to. Before accepting one, ask what's being counted: total area, dry land, or land people can actually use.

Three rankings, three different runners-up

Canada is the world's 2nd-biggest country by total area — and only the 6th-biggest by farmable land. Every bar above is drawn to the same scale, so its length is the country's real total area. The tick mark shows how much is dry land once inland water is subtracted. The teal bar shows how much is actually arable — land that could grow crops, the roughest available proxy for "usable." Notice how small the teal bars are next to the full territories.

Canada's slide isn't a data quirk — it's two real geographic facts compounding. About 9% of Canada's total area is fresh water (it holds more lakes than the rest of the world's countries combined), which alone drops it from 2nd to 4th once you count land only. Most of what's left is boreal forest, tundra, or Arctic permafrost — only about 4.3% of Canada's land is arable, one of the lowest shares of any large country. The United States, by contrast, has plenty of temperate, non-mountainous land suited to agriculture: over 16% of its land is arable, more than triple Canada's share — enough to make the 3rd-largest country by total area the largest by usable farmland, roughly tied with India, which is not among the six largest countries by area but has about half of its land in crops.

Total-area rankings for the U.S. and China specifically vary by a small margin across sources depending on how coastal waters and territories are counted — the CIA World Factbook convention used here (U.S. 3rd, China 4th by total area) is the most commonly cited, but at least one UN-statistics-derived source reverses that order. Arable-land ranks are world ranks, which include India (not one of the six countries shown). The two are close enough to swap places by year and source: FAO's 2019 figures put the U.S. at about 157.7 million hectares and India at about 156.1 million.
