I have tried the usual shortcuts and tried to find something in preferences but have had no luck. It is mentioned in another thread that it's not possible, but can someone confirm? I am using 2016b.

Hi Neil,
In R2016b there is no option to change the font size in 'App Designer'

As of R2019a you can control the font size of the App Designer editor from the preferences panel. mathworks.com/help/matlab/creating_guis/app-designer-preferences.html
You can also zoom the entire App Designer window using ctrl+mouse wheel or ctrl and + or - and ctrl + 0 to restore.

Just started using app designer, finally I can ditch VB for GUIs! But...I work on multiple monitors of different quality, diagonal size, and dot pitch/resolution. The app editor REALLY needs options to set font size and contrast, overall it is the visually toughest GUI I have to use, AND it has no adjustability!! Pease don't invent anything fancy, just the controls from regular Matlab editor would be fine.

To be more specific, a lot of the entire GUI is small grey text on a slightly different grey background - very hard to read. On my GPU if I pull the "extra gamma" slider down to 0.5 from 1.0 the GUI is far easier to read, but the rest of Windows is of course too dark. Suggestions: 1. Increase contrast between text and background to normal Matlab levels. 2. Add ability to change editor font size. 3. Add ability to change ribbon/menu/library size, although contrast is more important.

Well...I just came back a year later with 2017a...and app designer is still a low contrast, small font, unadjustable, unreadable nightmare. Unlike every other code editor ever. Even Notepad is adjustable. My only guess is no-one at Matlab has every tried to use this "editor". :-(

Here's a composite screen cap example. Left is illegible App designer, right is normal Matlab editor. For a correct comparision, set browser magnification so the right side is your normal code size. Then try to read the left side.

Dear Melissa, can you actually connect to the person responsible for App Designer and report our problems? Or, alternatively, there must be a way to solve the issue by editing internal Matlab files like .xml, .css, .js.
