For clarity, I'm not referring to launcher or icon size.

Using std Ubuntu 12.04 32 bit for an htpc. tweaking font settings for clickability at 3+ meters or 10 ft makes the font too big to fit into the gnome panel. I can`t seem to find where to adjust this size. I`ve added unsettings, ubuntu and gnome tweaks. I seem to recall the adjustability in lubuntu (though I could be wrong), but it was straight forward, and I didn't need it at the time. I've looked at etc/gnome* files, too but nothing jumped out at me.

somewhere the panel size must be defined... but where?
