Poor vision

Hi @GertFrobe:

I want to point out that in the same dialog box you can also increase the size of the anchor points, sizing handles and bounding box visual aids independently of the the UI scaling. When I'm teaching how to use the Direct Selection tool it is impossible for my students to see the tiny anchor points on my screen to figure out if an anchor point is selected, or not. Making them larger is invaluable in that situation.

Note that in my demo below I jumped from Small to Large and skipped the two intermediate steps. There are four choices—I'm just showing the two extrememes.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

I'm actually taking a break from looking for my misplaced glasses! Fortunately I have already set my phone up for increased font size when I can't find my glasses 🤓

The setting you are looking for can be found in Edit -> Preferences -> User Interface Scaling.  (If you are on a Mac, I think it is InDesign -> Preferences -> User Interface Scaling.) You can use the slider to increase the size of the interface, but it won't take effect until you restart InDesign
