I haven't had to use it on my screens but there is an icon_scale config
node in the gtk plugin that works both
on gtk2 and gtk4 and lets you set a scale factor to anything as a float.

This allows you to:

- scale up the icons by 2, 3 or whatever factor you need

- set the font size in your gtk2 theme

- enable the cross-grid feature so grid points get a 3x3 pixel cross instead
of a single pixel

Regards,

Erich
