Largest Countries by Land Mass – Top 10 Rankings and Facts

When measuring the Earth by sheer territorial extent, a small number of nations command extraordinary proportions. From the frozen expanses of Siberia to the tropical breadth of the Amazon, the ten largest countries by land mass together cover roughly half of the planet’s total land area. Understanding how these rankings are determined requires examining not only the figures themselves but also the measurement standards that produce them.

Russia holds the uncontested lead, followed closely by Canada in second place. The positions beyond the top two, however, become less straightforward. Differences in how sources define total area, whether to include inland waters, and how to treat disputed territories mean that the rankings for third and fourth place can vary depending on the reference used. This article examines the verified data, the sources behind it, and the nuances that shape the way these vast nations are ranked.

The figures presented draw from multiple authoritative sources, including the United Nations Statistics Division, the CIA World Factbook, Britannica, Wikipedia, World Population Review, and Statista. Where discrepancies exist, they are noted explicitly rather than smoothed over. Readers seeking to verify individual country measurements can consult the Wikipedia list of countries and dependencies by area or the CIA World Factbook directly.

What Are the Top 10 Largest Countries by Land Mass?

The ten countries listed below represent the most comprehensive ranking based on total area figures consistently reported across multiple major sources. All figures are expressed in square kilometers and include land mass combined with inland water bodies.

• The United States and China are separated by roughly 200,000 to 270,000 km² depending on which source is consulted.
• Brazil ranks fifth with the Amazon basin comprising a substantial portion of its 8.5 million km².
• Australia is the smallest continent while simultaneously being the sixth-largest country by area.
• Kazakhstan holds the distinction of being the largest landlocked country in the world.
• Algeria rounds out the top ten as the largest country on the African continent.

Complete Top 10 Table by Total Area

Is Russia the Largest Country by Land Size?

Russia’s status as the largest country on Earth is unambiguous. Its total area of approximately 17.1 million square kilometers places it roughly 7.1 million km² ahead of its nearest competitor, Canada. No major source disputes this ranking. The country spans two continents, extending from Eastern Europe across the entirety of northern Asia, and crosses eleven time zones. Its land mass represents about 11 percent of all the dry land on the planet, a proportion unmatched by any other nation.

The scale of Russia creates geographic and climatic extremes that few other nations experience. Approximately 65 percent of its territory lies in Siberia, where temperatures regularly plunge below minus 30 degrees Celsius in winter. The northernmost settlement of Canada shares similar Arctic conditions, yet the two countries reach their vast sizes through entirely different configurations. While Russia’s territory stretches unbroken across a single landmass, Canada occupies the northern portion of a continent with significant coastal exposure on three sides.

No disputed territory materially affects Russia’s ranking. Even the annexation of Crimea in 2014, which remains unrecognized by much of the international community, adds only approximately 27,000 km² to the total—an amount too small to shift any positional ranking among the world’s largest countries.

How Does US Land Area Compare to China and Others?

The third and fourth positions on the global ranking belong to the United States and China, but the order depends entirely on which measurement methodology is applied. According to the United Nations Statistics Division and the CIA World Factbook, the United States ranks third with approximately 9.83 to 9.87 million km². Both sources include territorial waters and coastal waters in their totals, a method that favors the United States due to its extensive coastline and large non-contiguous states such as Alaska.

Britannica and Wikipedia, however, reverse this order. These sources prioritize land area over total area, placing China at roughly 9.6 to 9.7 million km² slightly ahead of the United States. The difference stems from how each organization treats inland waters. China has comparatively fewer lakes and inland water bodies than the United States, which means its total area advantage shrinks when water is factored in differently across sources. The variation between the two countries amounts to between 200,000 and 270,000 km², a relatively narrow margin when compared to the gap between first and second place.

Both nations also incorporate territories whose inclusion can affect the total. The United States counts Alaska, Hawaii, Puerto Rico, and various Pacific and Caribbean territories. China’s total includes mainland territory, Macau, Hong Kong, and various islands. Each also holds disputed border regions that different sources may treat differently.

Where Brazil and Australia Stand

Below the US-China comparison, Brazil and Australia occupy fifth and sixth place respectively with clear consistency across all major sources. Brazil’s total area of approximately 8.5 million km² makes it the largest country in South America by a substantial margin. The Amazon basin alone covers roughly 5.5 million km², a region that influences both the country’s size ranking and its global ecological significance.

Australia, at approximately 7.7 million km², presents a unique case as the only nation that is also an entire continent. Its total area includes the mainland and smaller islands such as Tasmania. Unlike countries with significant inland water bodies, Australia’s measurements remain relatively straightforward, with no major disputes affecting its reported land area.

What Is Land Mass vs Total Area and How Is It Measured?

Understanding the distinction between land mass and total area is essential for interpreting why the same country can receive different measurements from different sources. Land mass refers strictly to the dry surface area of a country, excluding any bodies of water. Total area combines land mass with inland water bodies such as lakes, rivers, and reservoirs. The UN Statistics Division maintains standardized definitions that most international databases attempt to follow, though variations persist.

Several factors account for the variations observed across authoritative sources:

• Inland water inclusion: Some organizations include all lakes and rivers within recognized borders; others subtract them for a land-only figure. This single factor most directly explains the US-China ranking discrepancy.
• Coastal waters and continental shelf: The UN and CIA may include coastal waters or extend measurements to the edge of the continental shelf, adding significant area for countries with broad maritime exposure.
• Overseas territories: The United States includes Puerto Rico, Guam, American Samoa, and other Pacific territories. Whether these are included affects the final total.
• Disputed territories: Countries in conflict over border regions may report different figures depending on which government is doing the reporting.
• Rounding and projection methods: Geographic measurements derived from satellite imagery can vary slightly based on how coastlines and borders are digitized.

Disputed Territories and Their Impact on Rankings

Disputed territories rarely shift rankings within the top ten, but they introduce measurement variability that can affect reported figures. China’s disputed borders with India, including the Aksai Chin region, and its island claims in the South China Sea add area that different sources may or may not include. Russia’s annexation of Crimea in 2014 remains unrecognized by much of the international community, and the UN and many national governments do not credit the additional 27,000 km² to Russia’s official total.

Argentina’s Antarctic claims, which include territory overlapping with the UK and other nations’ claims, represent one of the larger potential disputed additions. However, most international organizations exclude Antarctic territorial claims from official rankings, recognizing that no sovereignty is universally recognized in the region.

Largest Countries by Land and Population: A Different Ranking

When land area is considered alongside population, a striking contrast emerges. Russia, the world’s largest country by area, is home to approximately 144 million people—roughly comparable to Japan’s population despite occupying more than 17 million km². Australia, the sixth-largest country, supports only about 27 million residents across its 7.7 million km². Both nations rank among the most sparsely populated on Earth.

China and India present the opposite pattern. China, the third or fourth-largest country by area with approximately 9.6 to 9.8 million km², is home to roughly 1.41 billion people. India, ranked seventh globally with approximately 3.3 million km², has surpassed China as the world’s most populous nation with approximately 1.45 billion residents. Together, these two countries represent over 2.8 billion people—roughly 35 percent of the world’s total population—while occupying a combined area that places them fifth and seventh among the world’s largest nations.

Smallest Countries in Europe by Land Area

At the opposite end of the scale, Europe’s smallest countries illustrate how dramatically area and population can diverge. The following figures are drawn from Britannica’s comprehensive country area data:

• Vatican City: approximately 0.44 km²
• Monaco: approximately 2.02 km²
• San Marino: approximately 61 km²
• Liechtenstein: approximately 160 km²
• Malta: approximately 316 km²
• Andorra: approximately 468 km²
• Luxembourg: approximately 2,586 km²

These microstates demonstrate that the relationship between territorial size and national significance is multidimensional. Monaco, with a land area of roughly 2 km², hosts one of the highest population densities of any sovereign territory, while Russia, with a land area over 8 million times larger, maintains a population density among the lowest on the planet.

Timeline: How Country Size Measurements Have Evolved

Territorial boundaries and their measurement have changed throughout history, though the top ten largest countries by area have remained remarkably stable for decades. The following timeline highlights key moments relevant to how these nations’ sizes are understood and recorded:

1. Pre-1945: Colonial empires and territorial conquests regularly reshaped global boundaries. The dissolution of the Austro-Hungarian and Ottoman empires after World War I created numerous new sovereign states.
2. 1945–1991: The post-war period saw the establishment of the United Nations and the adoption of standardized international boundaries. The UN Statistics Division began compiling geographic and land area data for member nations.
3. 1991: The dissolution of the Soviet Union created 15 independent republics from what was previously the world’s largest country. Russia retained the top ranking despite losing roughly 8 million km² to the newly formed nations.
4. 2014: Russia’s annexation of Crimea added approximately 27,000 km² to its effective control, though the international community widely considers this action unlawful and does not reflect the change in most official area measurements.
5. 2015–2020: China’s land reclamation activities in the South China Sea added an estimated 12 to 15 km² of new land through dredging operations. The NASA Earth Observatory has documented these changes through satellite imagery.

The top ten largest countries by total area have not changed composition in documented history. What has changed is the precision of measurement, the standardization of definitions, and the political treatment of disputed territories that may or may not appear in official tallies.

What Is Certain and What Remains Unclear?

Despite the comprehensive data available, certain aspects of country area measurements warrant careful interpretation. The table below distinguishes between what is well-established across sources and what remains subject to variation or uncertainty.

Context: Why Country Size Matters Geopolitically

A nation’s land area influences its resource base, strategic positioning, and geopolitical leverage, though the relationship is not always straightforward. Russia and Canada benefit from enormous territory that encompasses vast energy reserves, mineral wealth, agricultural land, and freshwater resources. Russia’s natural gas and oil fields, spanning regions from West Siberia to the Yamal Peninsula, underpin its role as a global energy power. Canada’s boreal forests and hydroelectric capacity represent some of the largest renewable resource stores on the planet.

At the same time, enormous territory presents governance challenges. Infrastructure development across remote and climatically extreme regions requires substantial investment, and vast land area does not automatically translate into economic or military dominance. Australia, despite its sixth-place ranking, operates with a smaller defense budget and fewer international military commitments than several much smaller nations. Kazakhstan’s 2.7 million km² make it Central Asia’s largest country, yet its GDP and population are modest compared to much smaller nations such as the Netherlands or Singapore.

The World Bank land area indicators track agricultural land, forest coverage, and land use changes over time, providing data that complements simple territorial measurements. These resources reveal that area alone tells only part of a country’s story—how that land is used, managed, and inhabited matters equally.

Sources Behind the Data: Who Measures Country Size?

Several organizations contribute to the body of geographic data that informs country size rankings. Each brings distinct methodologies, coverage priorities, and definitions that collectively produce the variations noted throughout this article.

The CIA World Factbook provides total area figures that include land and water within recognized boundaries, emphasizing comprehensive territorial measurement for each country profile. — CIA World Factbook

The UN Statistics Division maintains geospatial data standards that aim to harmonize how member nations report their territorial measurements, including inland waters and coastal baselines. — UN Statistics Division

World Population Review aggregates data from multiple authoritative sources including the UN, CIA, and national statistical offices, presenting comparative rankings that highlight where sources agree or diverge. — World Population Review

Summary: Key Takeaways on Largest Countries by Land Mass

Russia stands alone as the world’s largest country by total area, commanding approximately 17.1 million km² across eleven time zones and two continents. Canada holds a secure second position at roughly 10 million km². The third and fourth rankings remain genuinely contested between the United States and China, with each country favored by different authoritative sources depending on how inland waters and coastal measurements are treated. The remaining top ten—Brazil, Australia, India, Kazakhstan, Argentina, and Algeria—hold consistent positions across virtually all major sources.

Land mass versus total area represents the most significant factor behind measurement variations, and understanding this distinction is essential for anyone comparing country size data. The relationship between territorial area and population is equally revealing: China and India dominate by population while ranking third or fourth and seventh by land area, whereas Russia and Canada occupy enormous territory with relatively modest populations.
