Drag both across a Mercator map and watch how they change with latitude.

Lambert azimuthal equal-area projection centered on Oregon: it preserves areas, so both appear in their true proportion. The United Kingdom has been rotated across the globe, without changing its shape or size, until its center sits on the center of Oregon.

Which is bigger, the United Kingdom or Oregon?

People often say the United Kingdom is about the size of Oregon, and it’s true: they’re almost the same. Their populations, on the other hand, are nothing alike.

The difference is 4,320 sq mi (11,189 km²), roughly the size of the Gambia (4,361 sq mi).

The United Kingdom is the 78th-largest country in the world, and Oregon is the 9th-largest US state.

Population and density

The United Kingdom has a population of 69.5 million (World Bank, 2025) and Oregon 4.3 million (US Census Bureau, July 1, 2025 estimate).

That’s 739 per sq mi (285 per km²) in the United Kingdom and 43 per sq mi (17 per km²) in Oregon: the United Kingdom has 17.0 times as many people per square mile as Oregon.

Although it’s smaller, the United Kingdom has more people: 16.3 times as many as Oregon.

Why they look different on a regular world map

On the Mercator projection, used by Google Maps and many world maps, everything gets bigger the farther it is from the equator. The United Kingdom, centered at 54° N, comes out 2.9 times bigger than it really is overall; Oregon, at 44° N, 1.9 times.

That’s why on those maps the United Kingdom looks bigger than Oregon: on paper it takes up 1.45 times as much space, when in reality Oregon is 1.05 times as big.

That doesn’t happen on the map on this page: it uses an equal-area projection centered on Oregon. To move them across a Mercator map yourself, open them in the True size map.

From end to end

The longest straight line between two points of the United Kingdom is about 770 mi (1,240 km), running south to north; for Oregon it’s about 460 mi (740 km), southwest to northeast.

End to end, the United Kingdom is 67% longer than Oregon, even though it covers less area: its shape is more stretched out.
