How they differ
- Brittany is larger, but Massachusetts has the larger population: 7.0 million against 3.4 million, 2.05× as many people.
- Per square kilometre that is 332 in Massachusetts against 125 in Brittany: Massachusetts is 2.65× as densely populated.
- Their centres are about 5,260 km apart.
- A standard web map misstates the comparison: Brittany at 48°N is drawn about 2.2× too large and Massachusetts at 42°N about 1.8×, so the map shows Brittany as 1.59× the size of Massachusetts instead of 1.29×.
- Together Brittany and Massachusetts cover 48,500 km², close to the size of Slovakia (48,500 km², 0.1% smaller).
- The gap between them, 6,180 km², is about the size of Palestine (6,070 km²).
- At Massachusetts's density, Brittany would have 9.1 million people (it has 3.4 million). At Brittany's density, Massachusetts would have 2.6 million (it has 7.0 million).
- Brittany's centre is 5.9° of latitude, about 660 km, farther north than Massachusetts's.

- Massachusetts is the 45th largest of the 51 states and districts of the United States and covers 0.2% of its area; it is the 4th most densely populated of them.
- Brittany lies about 6° of latitude (roughly 659 km) north of Massachusetts.
- Shared out evenly, each person in Brittany would have about 7,990 m² and each person in Massachusetts about 3,010 m².

- Wikidata's official figure of 27,200 km² agrees with our measured area of 27,300 km², to within 2%.
- Our measured 21,200 km² is 23% below Wikidata's official figure of 27,300 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. The outline of Brittany is the departments Natural Earth draws there, joined along their shared borders.
- 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.
