I didn't mention the height. But for reference, at the back it's
about 6.5 cm.

No, of course not. We're talking maps, which use two-dimensional
coordinates, so the height doesn't enter into it. FWIW, my keyboard
in north-south direction is 51 cm or 0.0000046° wide, and in east-west
direction it's 0.000002° deep.
It's interesting to note that phk has specified a location to 7 places
of decimals in north-south direction. That's a resolution of a little
over a centimetre.

This is irrelevant in the current situation.
