understanding font size

Just out of curiosity, what is the unit for font size? koreader only displays a numerical value. Thank you for your attention.

It's just that: a numerical value ;p. Probably not even close to a point, given how it's affected by potentially-user-configured DPI scaling.

It gets thrown through the usual blender of DPI scaling according to user-preference, which leads to a value in pixels, and, for reflowable content, that is run through a sieve to round it to the nearest integer value in a scale of supported values (a scale recently updated to basically offer full granularity in steps of 1px).
In the end, CRe honors a px value (you never get to actually see that value, but you could, with a simple well-placed print statement).

Hi

What does DPI do? The default is 96 but when I increase the DPI I don't see much change. Does increasing it make it better to look at text?

For reasons that aren't completely clear to me the program's DPI and the crengine DPI aren't completely linked. Generally speaking you'll see more of a difference by playing around with Settings → Screen.

Oh, right, yeah, what @Frenzie said. The DPI button in the bottom menu is indeed... weirder .

I think it's preferable to increase the crengine DPI (in the bottom menu) btw. You definitely see it with certain CSS units as well as image size.
