How they differ

Schleswig-Holstein is larger, but Île-de-France has the larger population: 12.4 million against 3.0 million, 4.19× as many people.
Per square kilometre that is 1,023 in Île-de-France against 191 in Schleswig-Holstein: Île-de-France is 5.35× as densely populated.
Their centres are about 792 km apart.
A standard web map misstates the comparison: Schleswig-Holstein at 54°N is drawn about 2.9× too large and Île-de-France at 49°N about 2.3×, so the map shows Schleswig-Holstein as 1.62× the size of Île-de-France instead of 1.28×.
Together Schleswig-Holstein and Île-de-France cover 27,500 km², close to the size of Solomon Islands (27,200 km², 1.2% smaller).
The gap between them, 3,330 km², is about the size of Turkish Republic of Northern Cyprus (3,320 km²).
At Île-de-France's density, Schleswig-Holstein would have 15.8 million people (it has 3.0 million). At Schleswig-Holstein's density, Île-de-France would have 2.3 million (it has 12.4 million).

Île-de-France is the 13th largest of the 18 regions of France and covers 1.9% of its area; it is the most densely populated of them.
Schleswig-Holstein lies about 5° of latitude (roughly 608 km) north of Île-de-France.

Sources and method

Outlines: Natural Earth, 1:10m Admin 1 - States, Provinces, public domain. The outline of Île-de-France 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.
