The largest countries in the world by area in 2026

What Is the Largest Country in the World?

Russia is the largest country in the world, at 17,098,242 square kilometres (6,601,665 square miles). The scale is difficult to hold in the head: Russia covers roughly 11 percent of all land on Earth, spans 11 time zones, stretches 9,000 kilometres from the Baltic exclave of Kaliningrad to the Bering Strait, and is larger than the United States and China put together. It is nearly twice the size of Canada, the second-largest country, and bigger than the entire continent of Antarctica.

Country size sits alongside population as one of the two basic facts about any nation, and the two rarely line up, as our world population statistics make clear. India ranks only seventh by area yet holds more people than the nine countries above it combined, while Russia holds 11 percent of the land and 1.7 percent of the people. Where those people actually cluster is a separate story again, set out in our largest cities in the world analysis.

The full list runs to 195 sovereign states covering about 148.9 million square kilometres of land, roughly 29 percent of the planet surface. The distribution is extraordinarily lopsided: the ten largest countries hold close to half of all land, the twenty largest hold around 60 percent, and the smallest hundred together account for under 5 percent. Between Russia and Vatican City, at 0.44 square kilometres, sits a size ratio of about 39 million to one, one of the widest gaps in human geography.

One definition decides most of the argument. Total area, the measure used in almost every ranking including this one, means land plus inland water: lakes, rivers and reservoirs count, but territorial seas and exclusive economic zones do not. Land-only area excludes the water entirely. That single choice reorders positions two through four, which is why two reputable sources can publish different lists and both be right, and why any serious ranking of the largest countries in the world has to state its measure up front.

Canada is mostly lakes; Russia is mostly land: Russia holds 16.4 million km2 of dry land, while nearly 900,000 km2 of Canada total area is inland water, more than any other country on Earth.

Top 20 Largest Countries by Area, 2026

Before the rankings, one caution about precision. Area figures look exact, down to the last square kilometre, but they rest on surveys, projections and political judgements that carry real uncertainty, and a country coastline or river border can shift the total by thousands of square kilometres depending on where the line is drawn and when it was last measured. The numbers below are the best available consensus figures, not immutable constants.

The table ranks the 20 biggest countries by total area, with land-only area, share of world land and population density alongside. Reading across the rows shows how little size tells you about anything else: Mongolia is the eighteenth largest country and the emptiest on Earth at about 2 people per square kilometre, while India, seventh by area, packs in 489. The steep drop after the top five is the other thing to notice, since Brazil at 8.5 million km2 is more than triple Argentina at number eight.

What Are the Top 10 Largest Countries in the World?

The ten largest countries in the world by total area are Russia (17.1M km2), Canada (9.98M), the United States (9.83M), China (9.60M), Brazil (8.52M), Australia (7.69M), India (3.29M), Argentina (2.78M), Kazakhstan (2.72M) and Algeria (2.38M). Together they cover nearly half of all land on the planet while holding about 47 percent of its people, and they include the largest country on every continent except Europe, where Russia also happens to top the list.

The shape of the ranking is a cliff rather than a slope. Russia is in a class of its own, then four countries cluster between 8.5 and 10 million km2, then Australia sits alone at 7.7 million, and after that the numbers collapse: India, at seventh, is less than half of Australia and less than a fifth of Russia. By the time the list reaches Algeria at tenth, the areas have fallen below 2.4 million km2, and by twentieth place, Chad, they are down to 1.28 million. Only 20 countries on Earth exceed a million square kilometres at all.

It is worth pausing on how thinly those giants are spread. Six of the top 10, Russia, Canada, the United States, Brazil, Australia and Kazakhstan, are among the least densely settled large countries on the planet, and much of their territory is desert, tundra, rainforest or mountain. Only India and China combine enormous size with enormous populations, which is a large part of why they dominate global economic and demographic conversation while Canada and Australia, despite being physically vast, rarely enter it on scale alone.

A steep drop after the big five: Russia stands alone at 17.1 million km2, four countries bunch between 8.5 and 10 million, and by twentieth place the figure has fallen below 1.3 million km2.

Why Is Russia the Largest Country in the World?

Russia size is the product of four centuries of eastward expansion across Siberia, a landmass that was sparsely populated and offered little organised resistance, unlike the crowded borders to its west. From the sixteenth century onward, fur traders, cossacks and imperial administrators pushed the frontier from the Urals to the Pacific, and by 1867 the empire had stretched so far it sold Alaska to the United States. What remains is a country that touches 14 nations, crosses 11 time zones and holds the world fourth-longest coastline at 37,653 kilometres.

The catch is that most of it is barely habitable. Around two-thirds of Russia sits on permafrost, and the vast majority of its 144 million people live west of the Urals in the European fifth of the country, leaving Siberia and the Far East nearly empty. The result is a nation with 11 percent of the world land and about 1.7 percent of its population, though that emptiness contains enormous mineral, gas and timber reserves that anchor its place among the largest economies in the world despite a modest showing in GDP per capita terms.

The size also carries costs that rarely show up in a ranking. Governing 17 million square kilometres means maintaining roads, rail, power and defence across distances that would swallow most countries whole, and the Trans-Siberian Railway alone runs 9,289 kilometres, taking about a week end to end. Permafrost thaw is now buckling that infrastructure as the Arctic warms, and Russia far east is emptying out as people move west, so the practical map of the country is smaller than the political one.

Russia alone holds 11 percent: one country covers more than a tenth of all land on Earth, while the five largest together hold over a third and the smallest hundred share under 5 percent.

Is the US or China the Third Largest Country?

This is the most-argued ranking in geography, and both answers are defensible. By total area, which includes inland and coastal waters, the United States ranks third at 9,833,517 km2 and China fourth at 9,596,960 km2, the order used by the CIA World Factbook and most standard sources. Counting land alone, China (9,388,211 km2) overtakes the United States (9,147,593 km2), because a meaningful slice of the American figure is water, including the Great Lakes and coastal waters that the US counts and China largely lacks.

The same quirk decides second place. Canada total of 9,984,670 km2 includes almost 900,000 km2 of lakes, more inland water than the rest of the world combined, so on land alone Canada falls behind both China and the United States to fourth. In other words the entire order from second to fourth depends on a definition rather than a fact, which is why reputable sources disagree and why any credible ranking has to say which measure it is using. Russia first place, at least, is unchallenged either way. For the American figures behind these debates, see our US GDP report and US population data.

There is a second wrinkle in the American number. The US total of 9,833,517 km2 includes the Great Lakes and coastal waters, but different US agencies have historically published figures from 9.37 million to 9.83 million km2 depending on what they counted, which is why older sources sometimes place the United States fourth or even below China. China figure is comparatively clean, since it has far less inland water, so its ranking moves less between measures than any of its rivals.

Drop the lakes and the order changes: counting land only, China rises above the United States and Canada falls to fourth, which is why sources disagree on who ranks second, third and fourth.

Which Country Is Largest on Each Continent?

Russia is the largest country on two continents at once, since it is both the biggest country in Europe and the biggest in Asia, straddling the Ural divide. Elsewhere: Canada leads North America at 9.98 million km2 and the Western Hemisphere overall; Brazil leads South America at 8.52 million km2, covering nearly half the continent; Australia leads Oceania at 7.69 million km2, being the only country there of any size; and Algeria leads Africa at 2,381,741 km2, a title it took from Sudan when South Sudan seceded in 2011.

The pattern reveals how unevenly the continents are carved up. South America has 12 countries and Brazil takes 47 percent of it, while Europe packs roughly 44 countries into a smaller landmass than Brazil alone. Africa, the second-largest continent, is split among 54 nations, which is why its biggest country ranks only tenth globally. The commercial consequences of that fragmentation run through everything from trade to travel, as our most visited countries data illustrates.

Russia tops two continents at once: it is the largest country in both Europe and Asia, while Canada, Brazil, Australia and Algeria lead North America, South America, Oceania and Africa.

Does a Bigger Country Mean More People?

Almost the opposite, in fact. Ranking countries by area and by population produces two lists that barely resemble each other. India is seventh by area but first by population, with more than 1.45 billion people, while Russia is first by area and ninth by population. China, fourth by area, is second by population, as our China population data details. Canada is second largest on Earth and holds fewer people than Poland; Australia is sixth and holds fewer than Nepal.

The reason is climate and terrain rather than coincidence. The biggest countries got big partly by absorbing land nobody was competing for, which usually means desert, tundra, ice or mountain: Siberia in Russia, the Arctic in Canada, the Outback in Australia, the Sahara in Algeria. Habitable land, not total land, drives population, which is why fertile river valleys and coastal plains hold the crowds, and why migration flows toward a handful of temperate, developed magnets, a pattern our US immigration statistics capture.

A useful way to see this is arable land rather than total land. Only about 7 percent of Russia is arable, against roughly 56 percent of India, so despite being five times larger Russia has less farmland than India in absolute terms. Canada arable share is under 5 percent and Australia about 6 percent. The countries that feed the most people are rarely the biggest ones on the map; they are the ones whose land happens to be flat, watered and temperate.

Size and population rarely match: India ranks seventh by area and first by population, while Russia ranks first by area and ninth by population, and Canada is second by area but 38th by population.

Which Large Countries Are the Emptiest?

Among the ten largest countries, the density spread is enormous. Australia (3.5 people per km2), Canada (4.4) and Russia (8.5) are among the emptiest places on Earth, while India, seventh by area, carries 489 people per km2, making it about 140 times denser than Australia. China sits at roughly 148 and the United States at 37, so even within the giants there is no common pattern at all.

Mongolia, eighteenth by area, is the least densely populated sovereign country in the world at roughly 2 people per square kilometre, the result of a landlocked steppe-and-desert geography with brutal winters. At the opposite end, micro-states such as Monaco and Singapore run past 8,000 and 20,000 people per square kilometre. Density shapes almost everything downstream, from infrastructure costs to how people shop and connect online, themes that run through our retail e-commerce data and social media statistics.

National density averages mislead badly in big countries, though, because they divide people by land that nobody lives on. Canada average of 4.4 people per km2 is close to meaningless when roughly 90 percent of Canadians live within 160 kilometres of the US border, and Australia average of 3.5 hides the fact that most of its population sits in a handful of coastal cities. Measured against habitable land alone, both look far more like ordinary developed countries, which is the more useful comparison.

India is 46 times denser than Russia: among the ten largest countries, Australia, Canada and Russia are nearly empty, while India packs in 489 people per square kilometre.

Which Country Has the Longest Coastline?

Canada has by far the longest coastline in the world at about 202,080 kilometres, more than five times Russia 37,653 kilometres despite Russia being nearly twice its size. The reason is the Arctic Archipelago: over 36,000 islands, each contributing its own perimeter, wrapped around a deeply indented northern shore. Indonesia (54,716 km) and Norway (58,133 km) rank high for the same reason, thousands of islands and fjords rather than sheer national size.

Coastline figures come with a warning, known to mathematicians as the coastline paradox: the finer the measuring stick, the longer the answer, because every bay contains smaller bays. A coastline measured at 1-kilometre resolution can be several times longer than the same coast measured at 100-kilometre resolution, which is why national figures vary so much between sources. The practical point stands regardless, that some large countries are overwhelmingly maritime while others, such as Kazakhstan and Mongolia, are landlocked entirely.

Coastline matters commercially far more than raw area does. A long, usable coast means ports, fishing grounds, offshore energy and an exclusive economic zone stretching 200 nautical miles out to sea, which is why countries such as Indonesia and the Philippines punch well above their land ranking in maritime terms. Kazakhstan, ninth largest country on Earth, has no ocean access at all, and that single fact shapes its trade routes, its costs and its politics more than its 2.7 million km2 ever could.

Canada dwarfs everyone: at about 202,080 km, Canada coastline is more than five times Russia and longer than the next several countries combined, thanks to its 36,000-island Arctic archipelago.

What Is the Smallest Country in the World?

Vatican City is the smallest country in the world at 0.44 square kilometres, small enough to see in its entirety from the dome of St Peter Basilica and smaller than many city parks. Monaco follows at 2.02 km2, Nauru at 21 km2, Tuvalu at 26 km2 and San Marino at 61 km2. The gap between Russia and Vatican City comes to roughly 39 million to one, a ratio with no parallel in any other national statistic.

Small does not mean poor or unimportant. Monaco, San Marino and Liechtenstein rank among the wealthiest places per person on Earth, as our richest countries in the world ranking shows, and micro-states host outsized shares of global finance and corporate registration. Several of the smallest, however, face an existential problem that no ranking captures: low-lying island nations such as Tuvalu and Nauru sit only metres above sea level, so their area is not merely small but shrinking.

Vatican City fits inside a park: at 0.44 km2 it is the smallest sovereign state on Earth, about 39 million times smaller than Russia and visible in full from a single rooftop.

How Has the Map Changed Since 1946?

The number of sovereign countries has more than doubled in 80 years, from 76 in 1946 to 195 today. Decolonisation across Africa and Asia through the 1950s and 1960s added dozens of states, the collapse of the Soviet Union in 1991 added 15 at once, Yugoslavia fragmented into seven through the 1990s, and the newest arrival, South Sudan, seceded in 2011, an event that handed Algeria the title of largest country in Africa. Almost every change since 1946 has made countries smaller and more numerous rather than larger.

Outright territorial change is now rare and contested. The last widely accepted enlargement of a country by conquest was decades ago, and the post-1945 international order treats borders as effectively fixed, which is why annexations since 2014 have drawn sanctions rather than new lines on UN maps. Where areas do still shift, it tends to be through negotiated swaps, river-course changes, land reclamation, as in Singapore and the Netherlands, or the slow loss of coast to rising seas.

A few borders are still contested, and rankings quietly take a position by drawing them. Figures for Russia here exclude the territories in Ukraine, Georgia and Moldova that are not internationally recognised; Kashmir is counted under the administration recognised internationally rather than by claim; and Western Sahara, large enough to enter the top 60 on its own, is treated separately from Morocco. Antarctica, at 14 million km2, would rank second in the world if it were a country, but under the 1959 Antarctic Treaty it belongs to no one, and its claims are excluded from every national total.

Greenland is the other case that breaks most lists. At 2.17 million km2 it would rank twelfth in the world, ahead of Saudi Arabia, but it is an autonomous territory of Denmark rather than a sovereign state, so it does not appear in country rankings at all, while Denmark itself, at 43,000 km2, ranks around 130th. The same applies to French Guiana, Puerto Rico and dozens of other territories, which is why lists of the largest countries in the world and lists of the largest territories look quite different.

From 76 to 195 in 80 years: decolonisation, the Soviet collapse of 1991 and the breakup of Yugoslavia more than doubled the number of sovereign states, almost always by division rather than merger.

The Largest Countries in Numbers

A few numbers capture the geography of country size in 2026. Russia covers 17.1 million km2, 11 percent of all land, ahead of Canada at 9.98 million and the United States at 9.83 million. The world holds 195 sovereign states across 148.9 million km2 of land, the top 10 take nearly half of it, and the smallest, Vatican City, occupies 0.44 km2. Taken together, these figures describe a planet whose land is divided as unequally as its wealth, with a handful of giants holding most of the map and a long tail of small states sharing what is left.

Together these figures show that the largest country in the world is not merely a trivia answer but a lens on how borders were drawn, where people could actually settle, and which definitions a ranking chooses to use. Russia lead is beyond dispute; almost everything below it depends on whether you count the water. For anyone working with these figures, the safest habit is simple: state the source, state the measure, and remember that the map has been redrawn more often than it looks.
