Correct answer sanjaykr

With 18.1 update of Adobe illustrator,  we have added an UI option under preferences > User interface section to either turn off scaling completely or allow users to snap to lower or higher supported scale factor. Since Ai only supports 100%, 150% and 200% scale factors, users can choose to snap to 100% or 150% when his/her OS ui scale is between 100% to 150%. E.g. for 125% users can select lower supported scale factor to snap Ai ui to 100% and higher supported scale factor to snap to 150%. Similarly for OS ui scale 175%, users can snap AI's ui scale to 150% or 200%.

If you have defined the environment variable UI_SCALE_FACTOR=1, Then this preference will not work.

Yes, I was having this problem in Windows. I created a new environment variable called "UI_SCALE_FACTOR" with a value of 1, relaunched the app and now it's fixed.

Hello,

If you want to keep the windows scaling to 125% , 150% or any scale and still would like to keep Ai 's UI at 100% than you can define a system wide environment variable UI_SCALE_FACTOR=1

This will ignore the OS scale setting for Ai and will always launch in 100%.

Hi Matthias,

Below are the steps to set his environment variable.

1. Right click on "my computer" icon

2. Click properties,

3. Select Advanced System Settings or Advanced Tab (Based on your OS)

4. Click on the "Environment Variables..." button.

5. Click New... button on System Variables section, You can also set this in User Variables section, if you would like to keep the change limited to current logged in user.

6. In the "New system variable" dialog, enter UI_SCALE_FACTOR in variable name field

7. Enter 1 in the Variable value field

8. Click OK

Relaunch AI.

I don't think it's a bug, it's more like ignorance to force UI sizes and incredible inconsistencies of any kind on us.

At 125%

Photoshop, Premiere and After Effects come with small icons and menu font sizes.

Illustrator and InDesign on the other hand come with huge icons and menu font sizes.

At 124%

All look the same but Photoshop's and Acrobats menu font size is smaller than that of e.g. Illustrator.

Photoshops preferences to increase the UI font size seem to have no effect at all.

Are you really suggesting professionals should use Adobe tools to create Websites with a responsive Web Design, when Adobe themselves cannot even get close to a consistent and responsive user interface within their products?

Please do us a favour and build at least a checkbox into the preferences which UI enlargement we prefer, small, huge or ultra huge. You managed that for the experimental Photoshop preferences and 4K. So before you always wrong at least one half of your customers, give us at least a choice for the lesser evel.

And please ... don't force us to use Windows preferences as a switch for YOUR program behaviour.

Yeah, this question is NOT answered. My Windows scaling is set at 100%.  Illustrator CC is sized properly, but CC 2014 UI is giant.  Other CC 2014 applications are fine as well.   How does Adobe manage to muck up something so elementary.

This should be an easy and QUICK fix.

Correction.  My Windows font size is indeed set at the default 125%.  But this does not explain why AI CC looks fine (along with all the other CC 2014 desktop applications), but AI CC 2014 is giant.  Again, please fix this yesterday.

PS:  Please do not tell me to change the size to 124%.  That is an absurd solution that only serves as a dodge on Adobe's part.

EDIT:  InDesign CC 2014 is obnoxiously large too.  Ugh.

I switched to 100% and changed fontsize and other items in the advanced Win settings (Personalize/Windows Color (or something like that (I use a Dutch Win7))). Fiddling for an hour or so made things workable. AI and ID are good now.

Hours to make it all work again, yesterday and today: app. 5!!! Thanks, Adobe.

124% Windows font size seems to fix this.

Indeed. But some other windows are going to look vague, like Chrome's. Tried other Clear Type settings: no luck. Had to go back to 125%. The new versions of AI and ID are unworkable for me. PS and DW are good. Weird!!

Hi Levitsky,

It looks like your windows scale setting is >= 125% and Ai is scaling the UI to adapt to OS Scale settings, as in 17.1 it used to trigger at >=126% and many users complaint that Ai is not scaling at 125% scale which was case for most of the users. If you keep your windows scaling less than 125%, it will launch in 100% scaling.

Same problem here. I need 125% on my Win7 screens. Does this mean that I cannot use AI CC2014? It was good in CC.

I don't have CC so I can't test this, but apparently since 17.1 on Windows the illustrator UI scales to 150 or 200% depending on your OS scaling settings. it might have something to do with it:
