Ireland is 1.21× the size of Lake Michigan

Ireland (country) covers about 69,400 km² (26,800 mi²) and Lake Michigan (lake) about 57,500 km² (22,200 mi²). Below, both outlines are drawn at one scale and centred on each other. The Lake Michigan outline is Natural Earth’s, checked against the published area.

What fits

Lake Michigan is 83% of the size of Ireland.
Ireland is larger by 11,900 km² (4,600 mi²), which is 21% of the area of Lake Michigan.
Measured in Belgiums: Ireland is about 2.26, Lake Michigan about 1.88.

How they differ

Their centres are about 5,570 km apart.
A standard web map misstates the comparison: Ireland at 53°N is drawn about 2.8× too large and Lake Michigan at 44°N about 1.9×, so the map shows Ireland as 1.74× the size of Lake Michigan instead of 1.21×.
Together Ireland and Lake Michigan cover 127,000 km², close to the size of Nicaragua (129,000 km², 1.3% bigger).
The gap between them, 11,900 km², is about the size of Falkland Islands (11,600 km²).
Ireland's centre is 9.2° of latitude, about 1,020 km, farther north than Lake Michigan's.
Ireland ranks 122nd of 212 countries by area.
Lake Michigan is a lake and ranks 5th of the 104 lakes on sizeversus by area.
Laid out flat, Ireland stretches about 437 km north to south and 303 km east to west; Lake Michigan about 499 km by 255 km.
Poured over Ireland, the 4,918 km³ that Wikidata records for Lake Michigan would stand 71 m deep.
Wikidata’s published figure of 57,800 km² agrees with our measured 57,500 km², to within 2%.

Published figures: Wikidata (CC0). A lake or a sea has no legal boundary: the measured area is that of Natural Earth’s outline, and it is shown beside the published one.

Natural Earth’s outlines of the United States contain or lie within 4 km of the outline of Lake Michigan. That is what its geometry says, and it is not a statement about who owns the water or where any border runs in it.

Sources and method

Outlines: Lakes and seas: Natural Earth 1:10m physical vectors (public domain), kept only where the measured area is within 10% of the published one. Countries and regions: Natural Earth, 1:10m Admin 0 and Admin 1, public domain.
Boundary: De facto, as drawn by Natural Earth. A lake or a sea has no legal boundary of its own; the outline is a cartographic one.
Area: Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded. The published figure comes from Wikidata (CC0), fetched 2026-11-11, and is shown beside the measured one.
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.
