The Largest States in the US: A Complete Guide by Area and Population

When asking about the largest state, the answer depends on what you're measuring. The largest state by land area is Alaska, by a massive margin. The largest state by population is California, which holds the title for the most residents.

This guide provides the definitive Top 10 lists for both metrics, answers common comparison questions, and explores the data behind the biggest and smallest states.

Quick Facts: Largest & Smallest

Largest US States by Total Area (Top 10 List)

This list ranks the states by their total geographic area, including both land and water. The scale of Alaska is truly unique; it is more than twice the size of Texas.

Largest US States by Population (Top 10 List)

This list ranks the states by their total estimated population as of 2024. The top two states, California and Texas, are the only ones with populations over 30 million.

Common Comparisons: Area vs. Population

Many large states (by area) have very small populations, and vice versa.

Is Texas or California bigger?

By area, Texas is significantly bigger than California. Texas is the 2nd largest state at 268,596 square miles, while California is the 3rd largest at 163,695 square miles. You could fit California into Texas about 1.65 times.

By population, the situation is reversed. California is the most populous state, while Texas is second.

Which is bigger, Oregon or Wyoming?

By area, Oregon is slightly larger than Wyoming. Oregon is the 9th largest state at 98,379 square miles, while Wyoming is 10th at 97,813 square miles.

The most dramatic difference is in population: Wyoming is the least populated state in the entire country, while Oregon has roughly 7 times more residents.

What About the Smallest States?

The smallest states in the US provide a stark contrast to the giants on the Top 10 lists.

The Smallest State by Area: Rhode Island

The smallest state in the US by total area is Rhode Island. It covers only approximately 1,045 square miles, making it smaller than many individual counties in larger states.

The Smallest State by Population: Wyoming

The smallest state by population is Wyoming. Despite being the 10th largest state in terms of land area, it has the fewest residents, with an estimated population of only 584,000.

A Closer Look at the Giants

Alaska: The Vast Wilderness (The Largest by Area)

Alaska's size is difficult to comprehend. At 665,384 square miles, its landmass is vast, but it is one of the least populated places in the country.

It ranks as the 3rd least populated state, with only Wyoming and Vermont having fewer residents. Its immense size and low population density mean it is dominated by mountains, glaciers, and untouched wilderness.

California: The Population Powerhouse (The Largest by Population)

While only the 3rd largest state by area, California is the undisputed leader in population. With over 39 million residents,

it is home to approximately 12% of the entire US population. This population is concentrated in major economic and cultural hubs, making it a state defined by its dense cities, large-scale agriculture, and diverse economy.
