I had brought up this issue many years ago and still no solution has been offered.
When do you plan to enlarge the marked place on the screen and similar ones?
I hope you do not "in the middle of this century"!

Hello,

i have the same problem in the last version 23.0.2.
1920px document at 100% is 2900px width...

Please fix it, it is difficult to work correctly with this problem

Scaling looks like some workaround created in hurry, user interface loses clarity, menus are unnecessarily bigger, scaling objects becomes harder etc... All that is needed is ability to change UI font size (just like in photoshop)

and where does one find this slide bar. It is too small to see.... where is it???

Illustrator has a nice way to size the interface... what about InDesign? There is no slidebar, like the one in Illustrator?

Left side is a gradient mesh and to the right is a regular path. Why are the handles so small on the mesh object?

in addition to scaling it is also harder to MOVE an object when zoomed out.

In the CC illustrator version you have to zoom in SUPER far to be able to scale an object . A lot further than before. It starts rotating if you want to grab the object while you are still zoomed out, quite frustrating. This is the reason I do not use the CC illustrator version. It would be great if scaling possibilities would work like in the previous versions, it is much more user friendly. My fellow illustrators experience the same frustration.

Sorry, forgot to clarify, I'm in Windows 10 Build 17134.165

I have a Dell P2415Q (3840x2160px with scaling to 150%)

In response to @Raghuveer, is it fixed? Yes and no.
The slider works (and is more intuitive than previous option) but the elements size relations are weird. In the tiniest size, bars look alright for a tiny UI but the Start Screen is pretty big (what would look like a normal size, buttons are HUGE in relation to the rest of the UI) also the Tutorial screen is pretty big in relation with the rest (couldn't take a screenshot of this).
Here's my screenshots of sizes 1 to 3 (3 being normal): https://photos.app.goo.gl/bQhwxpoTMMU9fFJm7

Thanks for the fix, even with the current beta state it's much better than what we used to have.

I am afraid of beta softwares. When is the release?

The user interface scale is too small to be seen by the average person unless their nose is 6" from the screen. Not all users are 20 year olds on smart phones. PLEASE fix this as it's been an issue for years! Even with the "large tabs" option clicked, the entire interface is too small.

For the record, I'm using an iMac 27", I'm over the age of 35 with good eyesight, and really like Adobe. However, the interface makes me almost wish there was another product out there as good. Please fix this!

PS on a related note, it would be nice to control what Adobe wants to snap to, ie paths, intersections, anchors, etc. Would be super awesome to have a panel where you can disable them individually.

I've seen references to the beta build, am wondering if it is installed side by side with the regular version or if it replaces it on the users computer?

Same here - on every scaled High-Res-Screen i am having issues with microscopic icons and text :(

I use a 150% scaling of the Illustrator interface, but the rulers and size indicators remain 100%

Windows

And the rulers do not scale together with the UI.

I have the same issue, it drives me crazy. The same problem also occurs with InDesign.

No, only the size of the points changes, but not the size and position indicators

Illustrator ver.: 22.1 (64-bit)

Problem:

Since an update at the beginning of this year (I think), the UI scaling has become unusable on my laptop, which is an ASUS UX501VW with a 4k 15.6-inch screen. UI scaling is set to the maximum value (200%) but have a look at the screenshot on a 15.6-inch screen and you will see that it is not going to work out unless I put my face 20cm in front of the screen. Also the UI becomes extremely difficult to navigate because the buttons and menu options all become super tiny. Take a look at the screenshots of comparison.

Wierd enough, since the same update, the Photoshop UI scaling has improved dramatically. Before, the UI will either be super tiny at 100% scaling or super large at 200% scaling. I believe this change in UI scaling is related. Please take a look. Thanks in advance.
