I know that it is perhaps not the best contribution.
But my solution, a few weeks ago, was to stop using Cursor, instead using other alternatives, and to check every so often if Cursor is finally stable or working as before.
Not just because of this problem, but because of many other recurring ones.
i simply solve this with setting the Font Size to 15 then zoom in the whole IDE. If we can’t make the Chat Font Size bigger, we can make the IDE’s Font Size smaller then zoom in all of them. It’s pretty effective for me.
What good alternatives you recommend as of now?
This no longer works today, any altnernative?
Where do I add it? Adding it to settings.json had no effect, as mentioned by others it no longer seems to work.
Are you sure you installed this extension?
Yes. I couldn’t get it work, not with “reload config” and restarts. At some point all of a sudden it worked. But by then I had the font size set to 24. When trying to lower it a bit to 14 the font size got reduced back to the original and now I can’t get it bigger anymore.
I made it work using this answer:
But I agree that it should have been much simpler. I spent way too much time trying to figure this out 
I’m on Cursor v0.50.7 on ubuntu 24.04 and the new setting only changes the font size of the LLM text, the chat input box where we type the messages into is not respecting the change in the “Chat text size” setting.
I tried everything suggested here. Nadda.
So, I did what every code-pirate does: edit the source code. This will probably be overwritten with each app update, but it’s simple to edit again. I created a shortcut to the file and left myself the instructions below so that I can re-edit this in about 15 seconds.
Here’s the file location on Windows:
C:\Users\USERNAME\AppData\Local\Programs\cursor\resources\app\out\vs\workbench\workbench.desktop.main.css
Search for:
.aislash-editor-input
It will probably look like this:
.aislash-editor-input{cursor:text!}
Change it to this, or something similar:
.aislash-editor-input{cursor:text!important;font-size:16px!important;line-height:1.5!important}
Restart Cursor.
Happy Dance.
Note: you will likely see a little message “Your Cursor installation appears to be corrupt. Please reinstall.”
It appears after each restart. Just close it and move on. I find that it is a small price to pay for legible text.
Does not work well. At first, it worked; however, as long as I started chatting, the font size rolled back.
