- Hokkaido (Japan) is 68% of the size of Ohio.
- Ohio is larger by 37,300 km² (14,400 mi²), which is 47% of the area of Hokkaido (Japan).
- Measured in Belgiums: Ohio is about 3.78, Hokkaido (Japan) about 2.57.
How they differ
- Ohio also has the larger population: 11.8 million against 5.4 million, 2.17× as many people.
- Per square kilometre that is 102 in Ohio against 69 in Hokkaido (Japan): Ohio is 1.47× as densely populated.
- Their centres are about 9,650 km apart.
- Together Ohio and Hokkaido (Japan) cover 195,000 km², close to the size of Senegal (196,000 km², 0.7% bigger).
- The gap between them, 37,300 km², is about the size of Netherlands (37,100 km²).
- At Hokkaido (Japan)'s density, Ohio would have 8.0 million people (it has 11.8 million). At Ohio's density, Hokkaido (Japan) would have 8.0 million (it has 5.4 million).
- Hokkaido (Japan)'s centre is 3.0° of latitude, about 330 km, farther north than Ohio's.

- Laid side by side, Ohio and Hokkaido (Japan) would cover 195,000 km², about the same size as Senegal.
- Together they have 17.2 million people, about as many people as Guatemala.

- Wikidata's official figure of 116,000 km² agrees with our measured area of 116,000 km², to within 2%.
- Our measured 78,800 km² is 5.6% below Wikidata's official figure of 83,400 km². Official figures can include inland water or count land that an outline draws differently. This difference is flagged for review.

Sources and method
- Outlines
- Natural Earth, 1:10m Admin 1 - States, Provinces, public domain
- Boundary
- De facto, as drawn by Natural Earth. A region is drawn whole, every island included; a country is its main territory.
- Area
- Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded.
- 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.
