The United States is the third-largest country on the planet and occupies slightly less than 40% of the North American continent.

The US territory is divided into 50 states; 48 states are in the central part of the continent, known as the "contiguous United States," one state, Alaska, occupies the peninsula-like northwestern part of North America, and there is Hawaii, a tropical archipelago in the Pacific Ocean.

The states are constituent political units that together make up the United States.
The area of the 13 original states was largely defined by colonial charters and changed several times throughout their history. The size of many other state territories was determined by Congress. Relatively arbitrary straight lines following the lines of longitude and latitude defined the size of the states west of the Mississippi.


Measured by size, US states are as large or small as nation-states in the Old World. For example, California, the third-largest US state, is larger than Germany but smaller than France; Texas is three times the size of the United Kingdom, and Massachusetts is two-thirds the size of Switzerland.

Below is a list of the 50 US States by area size. From the largest to the smallest state of the United States.
