This is a critical function since I work in Premiere Pro almost daily. It worked a couple of years ago, and now with 4K and 8K screens, it no longer is a minor bug.

I use 4k monitors set at the higher resolutions. My biggest issue with font size is that I can't increase them for the Effects and Media Browser tabs. I would like to be able to increase font size a bit beyond the current largest setting.

If "across the board" means in all applications then that is a viable option. But it's not for those who are happy with the Windows font-size as-is but only having trouble with PrPro.

Premiere conforms to the Windows UI scaling. This is relatively new.
Have you tried increasing it in the windows control panel "Display" section, under "scale and layout" ? I've attached a picture.
Set it to 150% or something. Everything will get bigger, but slightly blurry, since it's a kinda lame bilinear upscale. However, when you restart, Premiere will use its own native scaling instead, so it'll no longer be blurry.

Agree absolutely. And need better contrast options - I do not work in a cave and I do not have 30:20 vision.

I endorse this request.

Yes please! I use the comments field in the marker panel constantly to annotate my footage make selections - often with detailed descriptions. I am constantly leaning in and squinting to read my own notes.

Other Adobe apps like Photoshop and Illustrator have scaling options built into them, so hopefully this is in the works for Premiere too.

Yes! I just upgraded from 2017 and on my UHD monitor this is a big problem.

YES!!! I use a 4k monitor and I have to lean in to read it! I don't want to have to change my screen resolution; i want to make the fonts of the UI bigger or smaller in settings!

after effects and encoder also!
