A while back I found a community post (linked below) with a Rich Text formula to modify the field labels, though in my case it was to left align them rather than resize. You put the formula in one RTF field per table, then display that field on any form you want impacted. I typically stick this field at the bottom of my form and hide the label using the Alternate Label Text. I don't understand the mechanics, but having this simple formula in a field affects the entire form.
LeftAlign field formula:
"<img src onerror='$(\"table.LabelsLeft td.label,table.LabelsLeft label\").css(\"text-align\",\"left\");'>"
Since the forms are structured as tables, I imagine you could modify this formula to change the font size of the labels rather than the alignment. I have not tested this myself, though.
