Could not find setting for editor UIs' font sizes

trying to make the interface more readable, the fonts of the settings’ pages are hard to read with the small fonts:


Is there a mechanism I have not seen, or are these UI fonts of the atom-dialogs set in stone? (not the editor pane, I know where those settings are tweaked, already done)

I think you’re looking for Settings>Themes>UI Settings>Fonts

I’m using Atom Material UI and under Settings>Fonts I can adjust the font size, which changes the text size in the tree, tabs, and other menus. I’m not sure if other themes have the same feature but I can’t see why they wouldn’t.
