However I'm not at all clear how the system knows how big my display is, if I connect a smaller display to the same output then the text will be smaller even though I have changed nothing. Is the correct absolute size dependent on me having set up my display correctly at some point?
In fonts and printing there are always 72 points per inch. In theory monitors report their horizontal and vertical image sizes in millimetres via EDID. Windows ignores this and usually assumes 96 dots/pixels per inch, resulting in a 3pt to 4px conversion.
Unfortunately I can't remember if X-Windows on Linux takes a similar approach (more consistent) or the correct approach.
Hope this helps, Tim.
