How much bigger is Delaware than Rhode Island?
By land area Delaware is 1.88× Rhode Island: 1,949 sq mi against 1,034 sq mi in the Census Bureau's 2010 measurements. The difference, 915 sq mi, is 88% of Rhode Island's own land area. By total area, which adds inland, coastal and territorial water, the ratio is 1.61×: 2,489 against 1,545 sq mi. Water makes up 33% of Rhode Island's total area and 22% of Delaware's.
Rhode Island is the smallest state on both measures and Delaware the second smallest. The next state up, Connecticut, has 4,842 sq mi of land, 2.5× Delaware's. At the other end of the table, Alaska's land area is 293 times Delaware's and 552 times Rhode Island's.
Population: Rhode Island has more people on less land
On July 1, 2025 Rhode Island had 1,114,521 residents and Delaware 1,059,952 (Census Bureau, Vintage 2025): 54,569 more people in Rhode Island, 5% more, on 47% less land. Delaware is growing faster: it added 9,829 residents in the year to July 1, 2025 (0.9%), Rhode Island 4,106 (0.4%).
Per square mile of land that is 1,078 people in Rhode Island and 544 in Delaware, 1.98× as dense. Among the 50 states Rhode Island ranks 2nd for density, after New Jersey, and Delaware 6th.
Delaware has the larger economy. The Bureau of Economic Analysis puts its 2025 GDP at $121.9 billion and Rhode Island's at $88.2 billion in current dollars, 1.38× as much: about $115,043 per resident in Delaware and $79,174 in Rhode Island.
Coastline: Rhode Island has the most for its size in the lower 48
NOAA's general coastline, published in 1975 and taken from large-scale nautical charts, is 40 miles for Rhode Island and 28 for Delaware. Per 100 sq mi of land that is 3.9 miles in Rhode Island, more than any other state in the lower 48, and 1.4 miles in Delaware. On NOAA's tidal shoreline, which also follows sounds, bays, rivers and creeks to the head of tidewater, the two are almost level: 384 miles for Rhode Island and 381 for Delaware.
The first state and the last of the thirteen
Delaware: December 7, 1787
Delaware was the first state to ratify the Constitution, on December 7, 1787, by a unanimous 30 to 0 vote of its convention (National Archives). The US Senate counts it as the first state to join the Union.
Rhode Island: May 29, 1790
Rhode Island was the last of the thirteen original states to ratify. Its voters had rejected the Constitution in a referendum in March 1788. Threatened with being treated as a foreign government, the state called a ratifying convention in 1790, which ratified on May 29, 1790, by two votes (National Archives). The US Senate counts Rhode Island as the 13th state.
Counties: three in Delaware, five in Rhode Island
Delaware has three counties (Kent, New Castle and Sussex), the fewest of any state in the Census Bureau's 2020 county list, and all three are coded as active governments. Rhode Island's five (Bristol, Kent, Newport, Providence and Washington) are coded as “nonfunctioning legal entities”: they exist in law but have no county government. Connecticut's eight counties carry the same code, and no other state has every county coded that way.
Drawn to scale: Delaware next to Rhode Island
Both states at the same area per pixel. Delaware is 96 miles long and 9 to 35 miles wide, according to the State of Delaware.
Computed from our map data with a Mercator projection, Rhode Island is drawn at 1.79× its true area and Delaware at 1.66×, so on a Mercator web map Delaware looks about 1.7× Rhode Island's size instead of 1.88×.

- US Census Bureau, State Area Measurements and Internal Point Coordinates (2010). Total area adds inland, coastal and territorial water to the land; marsh and swamp count as land. Ranks are among the 50 states.
- Population
- US Census Bureau, Vintage 2025 population estimates (July 1, 2025). Density divides the July 1, 2025 population by the 2010 land area.
- GDP
