The United States is made up of 50 individual states that vary greatly in size. When talking about land area, Rhode Island ranks as the smallest. Yet, when we discuss population, Wyoming-the 10th largest state by area-comes in with the smallest population.
The 5 Smallest States by Land Area
If you're familiar with U.S. geography, you might be able to guess which are the smallest states in the country. Notice that four of the five smallest states are along the eastern coast where the states seem to be crammed into a very small area.

- Rhode Island is only 48 miles in length and 37 miles wide (77 x 59 kilometers).
- Rhode Island has over 384 miles (618 kilometers) of coastline.

2) Delaware-1,949 square miles (5,047 square kilometers)
- Delaware is 96 miles (154 kilometers) in length. At its thinnest point, it is only 9 miles (14 kilometers) wide.

The 5 Smallest States by Population
When we turn to look at the population, we get an entirely different perspective of the country. With the exception of Vermont, the states with the lowest population are among the largest by land area and they're all in the western half of the country.
A low population with a large amount of land means a very low population density (or people per square mile).
1) Wyoming-579,315 people
- Ranks as the 10th largest in land area - 97,093 square miles (251,470 square kilometers)
- Population density: 5.8 people per square mile
2) Vermont-623,657 people
- Ranks as the 45th largest in land area - 9,217 square miles (23,872 square kilometers)
- Population density: 67.9 people per square mile
3) North Dakota-755,393
- Ranks as the 19th largest in land area-69,000 square miles (178,709 square kilometers)
- Population density: 9.7 people per square mile
- Ranks as the largest state in land area-570,641 square miles (1,477,953 square kilometers)
- Population density: 1.2 people per square mile
5) South Dakota-869,666
- Ranks as the 17th largest in land area-75,811 square miles (196,349 square kilometers
