What fits
- Australia is 81% of the size of United States.
- United States is larger by 1,756,000 km² (678,000 mi²), which is 23% of the area of Australia.
- Measured in Belgiums: United States is about 308, Australia about 251.
How they differ
- United States also has the larger population: 340.1 million against 27.6 million, 12.3× as many people.
- Per square kilometre that is 36 in United States against 3.6 in Australia: United States is 10.0× as densely populated.
- Their centres are about 14,500 km apart.
- A standard web map misstates the comparison: United States at 45°N is drawn about 2.0× too large and Australia at 26°S about 1.2×, so the map shows United States as 1.98× the size of Australia instead of 1.23×.
- Together United States and Australia cover 17,138,000 km², close to the size of Russia (16,980,000 km², 0.9% smaller).
- The gap between them, 1,756,000 km², is about the size of Sudan (1,856,000 km²).
- At Australia's density, United States would have 34.0 million people (it has 340.1 million). At United States's density, Australia would have 276.4 million (it has 27.6 million).
- United States's centre is 70.5° of latitude, about 7,840 km, farther north than Australia's.

Sources and method
- Outlines
- Natural Earth, 1:10m Admin 0 - Countries, public domain
- Boundary
- De facto, as drawn by Natural Earth. Main territory: the largest landmass and every part within 1,000 km of it.
- Area
- Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded. Comparisons use main-territory area.
- Drawing
- Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
