Mmh, I'm unsure how much it helps to compare the different applications.
      * gedit is a native Gnome application and respects their desktop
        guidelines. --> 24x24 px toolbar icons, text below (always)
      * Firefox is a multi-platform application that (most of the time)
        respects platform specific rules --> 24x24 px toolbar icons, no
        text (which seems to be the default for Firefox)
      * LibreOffice is also multi-platform, but we care less about
        platform specific characteristics (mainly driven by saving
        effort ... for Windows, sharing toolbar and menu icons - no
        further comment on that) --> 16x16 px toolbar icons, no text

As said, our small toolbar icons are 16x16 px, the larger ones are 26x26
px. Thus, there is no way to perfectly align LibO/OOo to what the Gnome
Desktop defines/requires.

Moreover, one of our main problems is, that we do offer too many toolbar
elements per default ... thus we have to omit the labels and "hitting"
the buttons gets harder (due to their small size). Increasing the icon
size (better: automatic setting) will improve that, but we won't improve
the understandability of the metaphors :-)

Here is some more information ...

I don't know whether this helps in general, but in Gnome there is a DPI
setting that is used to scale the font display. At least for my screen
is 96x96 DPI (using the command above).

Cheers,
Christoph
