Mac OS 14.1, InDesign 19.1
Can confirm the feature is there and works, but introduces a bug. Once the UI is scaled above Small, View Actual Size is no longer accurate. There is already a thread on this.
Hopefully it is being tracked as a bug.

The jump between scaling options is too big and difficult to use, even the "small" option – see attached comparison with Illustrator.

Having the same number of scaling increments as Illustrator would resolve this.

My Creative Cloud Desktop app is not offering the InDesign 2022 version, and says I am up to date (with 2021).

Hi, any support for the Dell 8K monitor? Everything is too small!

This sucks – no way to increase UI Scaling on a Mac. Come on Adobe! So inconsistent! UI Scaling is in Photoshop, but not Illustrator or InDesign. I can make the anchor points (nodes) larger in Illustrator, but not in InDesign.

CONSISTENCY PLEASE!

Same UI Scaling options as Illustrator would be ideal, this really needs done – InDesign is causing unnecessary eye strain during longer sessions.

I'm glad to see this is labeled as started but is there any new updates when we will see a UI scale slider. It is pretty insane that you guys are only now starting to explore this.

This fixed it for me:
Go to your desktop icon>Properties>Compatibility>Change DPI settings
I changed the settings like so on the screenshot and it worked.

Good to hear Adobe is finally addressing this. It is a major accessibility issue for people with uncorrectable vision problems. A speedy solution would be greatly appreciated. I've gotten around this to some extent by changing the display resolution, but you can only go so far before the program becomes unusable.

Hi Abhinav,

great to hear you are on the case with this now, thank you.

One thing i’d like to throw into the mix which may be of use to you on this subject actually occurred as a bug/glitch of some sort while i was working in inDesign cc2019/20. I don’t know what i did to make it happen but i came back to my system after a break and woke it from sleep. And i found the inDesign UI frame tools/icons/rulers/etc showing as a fluorescent green one time and red on another occasion (more than once). And although this was obviously a bug of some sort, the truth is, i actually liked it! The fluorescent appearance of the icons, etc., just gave it all more clarity, even at the smaller sizes. After i finished the work for the day, or shutdown the system, next time i came back to it it will have disappeared.

It struck me that this could be a good feature/option to have as a preference and go some way toward a cure for the problem. I did write in to the community about this weirdness at the time, and i took screenshots more than a year ago but don’t remember getting any response. Anyhow, i’ve attached the two screenshots for you to see, hope this helps. And it would be good to hear what you think of this as a possible aid to the solution.

Best wishes,
Richard

Same goes for the handles on paths. I an barely see them, there should be an option to increase/decrease their size like in Illustrator

Adobe has today, via Twitter, confirmed that they are working on this feature for an upcoming update.

"Hi David, thanks for your patience. I am afraid I do not have any specific date, but the product team is already working to add this feature in future releases of InDesign. You may use this UserVoice(https://bit.ly/37nX7m6) to upvote & add your comment. Thanks! ^AM""

Still waiting...

Ironic commentary: We are waiting since 2017 cause they have not enough funds to set 1-2 programmers day by day for 1 month to implement this functionality.

Still waiting... meanwhile.... no answers... no advance.... struggling on a tiny/huge interface.

Will they wake up when Affinity make a big step forward? I think not...

96 comments dating back to 2017 and we are in 2021 with no good resolution to this. This is a needed update for individuals that are responsible for designing things. A blurry, scaled interface is a slap in the face for people that pixel peep. Let's face it, 4K is not exactly "new" technology.

Ignoring logical user requested updates like this only furthers the narrative that the membership fees are not worth it. I don't believe that is the case. I earn a living off your software. That being said, it is a pretty big issue when we're all trying to stay at the bleeding edge and we're waiting 4 years for updates that have been standard in other Adobe Software for years.

I got a new laptop with a HD 4k screen and its already scaled to 250% but the user interface is still too small. Even if increasing my OS scaling to 300%+ fixed it (which it doesn't), it would still be infuriating to have everything on my computer scaled that high all the time, or have to adjust it every time I wanted to use the program. I am a graphic design student and I am required to use Indesign for presenting and turning in every project/assignment I do. It worked great on my older laptop with standard resolution, but now it is really frustrating to try to do anything with the program.

I just don't understand why a professional-grade product doesn't account for high-resolution screens, or even include a simple in-program UI scaling slider or option.

Hi all -

I had this same issue. If you are on windows 10, try this.

Go to your display settings and make sure ALL monitors are set to 125% for scale and layout.

This fixed it for me.

Yesssssss, please get this fixed. The lack of feedback or fix from a professional public company is a bummer. It's a pretty huge annual subscription cost for something that has this problem and which has been fixed for Photoshop and Illustrator.

I have had this issue for over two years on a 4K Cintiq using Windows 10. InDesign is blurry when the system scaling is set to 200%, and it's unreadably small when the system is set to 100%. When is this NECESSARY feature going to be implemented in InDesign?

Just for giggles, set the scaling in the operating system to 200% and then set InDesign’s scaling to maximum.

Don’t forget to restart InDesign after making those changes. InDesign scales based on the operating system scaling factor for your monitor.
