The United States spans nearly 9.8 million km², but not all states share equally in that vast territory. The 10 smallest states by area could fit inside Alaska more than 100 times over. Despite their small size, many of these states punch far above their weight in population density, economic output, and historical significance. Here is the complete ranking.
10 Smallest US States by Total Area
| Rank | State | Total Area (km²) | Population (2025 est.) | Density (per km²) |
|---|---|---|---|---|
| 1 | Rhode Island | 4,001 | 1,112,000 | 278 |
| 2 | Delaware | 6,446 | 1,018,000 | 158 |
| 3 | Connecticut | 14,357 | 3,626,000 | 253 |
| 4 | New Jersey | 22,591 | 9,290,000 | 411 |
| 5 | New Hampshire | 24,214 | 1,402,000 | 58 |
| 6 | Vermont | 24,906 | 647,000 | 26 |
| 7 | Massachusetts | 27,336 | 7,033,000 | 257 |
| 8 | Hawaii | 28,313 | 1,440,000 | 51 |
| 9 | Maryland | 32,131 | 6,185,000 | 192 |
| 10 | West Virginia | 62,756 | 1,770,000 | 28 |
Rhode Island: America's Smallest State
Rhode Island covers just 4,001 km², making it smaller than many individual counties in western states. Despite its tiny size, it has an official name that is one of the longest: "State of Rhode Island and Providence Plantations" (shortened officially in 2020). You could fit approximately 425 Rhode Islands inside Alaska, the largest state. Despite its small area, Rhode Island has over 640 km of coastline thanks to Narragansett Bay, which reaches deep into the state.
New Jersey: Small but Densely Packed
While New Jersey ranks only 4th smallest by area, it is the most densely populated state in the entire country at 411 people per km². Its position between New York City and Philadelphia makes it one of the most urbanized corridors in America. Despite its "Garden State" nickname, nearly 95% of New Jersey's population lives in urban areas, and it has more diners per capita than any other state.
Small States, Big History
Many of the smallest states played outsized roles in American history. Delaware was the first state to ratify the US Constitution on December 7, 1787, earning it the nickname "The First State." Massachusetts was home to the Plymouth Colony (1620) and the cradle of the American Revolution, hosting the Boston Tea Party and the battles of Lexington and Concord. Connecticut is known as the "Constitution State" because its Fundamental Orders of 1639 are considered the first written constitution in the Western tradition.
Size Comparisons
To put these sizes in perspective: Rhode Island is about the same size as the county of Los Angeles, California. The entire state of Delaware is smaller than Yellowstone National Park. You could fit all 10 of the smallest states inside Texas and still have room left over. Hawaii, despite being an archipelago of 137 islands, has a total area smaller than Maryland. Vermont, while similar in area to New Hampshire, has less than half its population, making it one of the most rural states in the Northeast.
Why the Small States Are All in the North-East
Eight of the ten smallest states are in New England or the Mid-Atlantic, and the reason is chronology. They were surveyed and settled first, when boundaries were drawn around existing colonial charters, river systems and days of travel rather than across open territory.
The states admitted later were carved from federal land on a far larger grid. The Land Ordinance of 1785 established the rectangular survey system, and everything west of the Appalachians was divided into townships six miles square, which produced the straight-line boundaries and much larger units visible on any map of the American West.
Hawaii is the exception on this list, small because it is an archipelago rather than because of when it was drawn.
Small Area, Outsized Influence
Size has almost no relationship to political weight in the American system. Every state elects two senators regardless of area or population, which means Wyoming's 577,000 residents and California's 39 million have identical representation in the upper chamber.
New Hampshire has held the first presidential primary since 1920, a position protected by state law requiring it to schedule at least a week before any similar contest. Delaware's corporate law and Court of Chancery have made it the registered home of a very large share of publicly traded American companies, including a majority of the Fortune 500.
Rhode Island was the last of the thirteen colonies to ratify the Constitution, holding out until May 1790 over the absence of a bill of rights, having been the first to declare independence from Britain fourteen years earlier.
Density Is Where the Small States Lead
New Jersey is the most densely populated state at roughly 470 people per square kilometre, ahead of Rhode Island, Massachusetts and Connecticut. The north-eastern corridor from Boston to Washington is among the most continuously urbanised stretches of the developed world, and the geographer Jean Gottmann named it Megalopolis in 1961.
That density inverts the usual American pattern. Alaska, the largest state, has under half a person per square kilometre, so New Jersey is roughly a thousand times denser than the state that dwarfs it in area.
It also explains why the small states carry more economic weight than their size suggests: Massachusetts, Connecticut, New Jersey and Maryland all rank high in output per head, driven by finance, pharmaceuticals, higher education and proximity to the capital.
The Ones That Nearly Were Not States
Several of the smallest have unusual origins. Vermont existed as an independent republic from 1777 to 1791, with its own currency and postal service, after settlers rejected competing New York and New Hampshire land claims.
West Virginia was created during the Civil War, when the western counties of Virginia refused to leave the Union and were admitted separately in 1863. It remains the only state formed by seceding from a Confederate state.
Delaware, Maryland and Pennsylvania spent eighty years disputing their boundaries until Charles Mason and Jeremiah Dixon surveyed the line between 1763 and 1767. That survey later became the symbolic division between free and slave states, which is why a boundary settlement between three small colonies ended up naming a cultural fault line.
How the Ten Compare
All ten smallest states combined cover about 246,000 square kilometres, which is still substantially less than Texas alone at roughly 696,000, and a fraction of Alaska's 1.72 million. Around 425 Rhode Islands would fit inside Alaska.
Put another way, the entire north-eastern cluster occupies less ground than a single large western state while holding tens of millions more people, which is the clearest summary of how differently the two halves of the country were assembled.
The Quirks the Small States Are Known For
Delaware charges no sales tax, which makes its shopping centres a destination for residents of Pennsylvania, Maryland and New Jersey. New Hampshire does the same and adds no income tax on wages, funding itself through property taxes instead.
Rhode Island held the longest official name of any state, the State of Rhode Island and Providence Plantations, until voters shortened it by referendum in 2020 because of the word plantations. Connecticut's highest point, Bear Mountain at 725 metres, would not register as a foothill in Colorado.
Vermont has the second-smallest population of any state at around 647,000, ahead only of Wyoming, and is one of the few with no city above 50,000 residents.
What Counts as Area, and Why Rankings Differ
State area figures vary between sources because of what they include. Total area counts inland water; land area does not, and coastal states with large bays or lakes shift position depending on which is used.
Rhode Island is the clearest example: Narragansett Bay makes up a substantial share of its total area, so its land area is smaller still relative to the states just above it. Delaware and Maryland are similarly affected by Chesapeake Bay.
Michigan is the extreme case in the other direction, ranking far higher by total area than by land because of its Great Lakes waters. Any ranking of smallest or largest states should therefore say which measure it is using, and this one uses total area.
Hawaii, the Outlier on the List
Hawaii is the only entry not attached to the mainland, and it is small for a different reason: it is an archipelago of eight main islands and well over a hundred smaller ones, strung across 2,400 kilometres of Pacific.
It is also still growing. Kilauea on the Big Island has been among the most active volcanoes on earth, and lava entering the sea has repeatedly added new land, while the Loihi seamount to the south-east is building the next island beneath the surface.
It was the last state admitted, in August 1959, seven months after Alaska, which is why the two sit at opposite ends of almost every ranking: the largest state and one of the smallest joined the union in the same year.
