I don't know, however....

I never use Akregator, and never install *webkit* intentionally. I suspect 
your problem is related to why I never install *webkit*. AFAICT, WebKit has 
no support for the "physical" sizes that KDE depends on. That is, fonts in 
KDE are sized in points. A point is a physical size, 1/72" on paper, and 
1/72" on a PC screen only in cases where the DE's desktop pixel density 
matches the physical pixel density of the display. When they don't match, 
physical sizes essentially become logical sizes. Either way, these "physical" 
sizes are DPI dependent, that is, rendering a given "physical size" requires 
more pixels per glyph as display density increases beyond 96. In cases where 
density is below 96, most web browsers assume 96 regardless what the physical 
density actually is.

In WebKit, instead of a point attempting to equal 1/72", it corresponds 1:1 
to a pixel. Whether a WebKit pixel is physical or logical is something I'm 
not currently up to speed on, but you can see what I'm talking about by 
loading http://fm.no-ip.com/Auth/dpi-screen-window.html in various browsers. 
I've not tested FF 22 or 23 yet to see what if any difference(s) from 
previous versions may exist, but at least up through 21 you'll see a match 
between Firefox (or SeaMonkey up through rv21) and Konq configured to use the 
KHTML engine, compared to Chromium or Rekonq or Konq configured to use 
WebKit. The latter render point sizes in pixels, because that's the way 
WebKit is. If your display is at or near 96 DPI, you won't see a difference 
among the five. However as display density is increased more than nominally 
above 96, pixel sized objects get progressively smaller physically, while 
point sized objects do not - until DPI reaches 192. Beyond that point things 
get more complicated, which I won't try to get into here, and likely does not 
apply to the problem you seem to be describing.
