For some reason, the font-sizes on macOS appear very small.
For example, if I use Apple's own Pages and set the zoom to 100%, I would expect it to represent the page accurately on my display. However, it is actually way smaller on the display. The same holds for Microsoft's Word. Only Libre Office's Writer seems to get the right result.
So, I am wondering what might be going on there and whether something can be done about it.

This is on a MacBook Pro (Retina, 15-inch, Mid 2014), 2880-by-1800 resolution at 220 pixels per inch.
