I think the top of my answer [here](https://discourse.jupyter.org/t/is-it-possible-to-change-the-font-and-size-of-the-output-text/3383/2) may relate to your question. You’ll want to change `fontSize` in `Settings`. Although, it isn’t limited to the output font size.

UPDATE:  
In JupyterLab version 2.1.2, you can just go `Settings` \> `JupyterLab theme` \> `Increase Code Font Size` several times, and it will increase the font sizes from both the code and code output.

I changed it but it only changes for the text editor. What I want is an increase in the font size on notebook, which I can’t find

What you are talking about is true for input cells, but it doesn’t have any effect for output cells

What version of JupyterLab are you using? JupyterLab is very much under active development and you need to use the latest to take advantage of the many options being actively enhanced.

I just tested version 2.1.2 and you can increase the code and code output size both by repeatedly going to `Settings` \> `JupyterLab Theme` and selecting `Increase Code Font Size`. (Go [here](https://github.com/fomightez/bendit-binder) and use any launch badge button to confirm in your own browser.)

Just to clarify, does your output font size increase while you are working with notebooks or using text editor?

I use it through [MyBinder.org](http://MyBinder.org). You can say you want version 2.0. For example, see [here](https://github.com/fomightez/bendit-binder/blob/1c8da104d5c9c82a739639064ad418b99b1d8f7d/requirements.txt).

Thanks, I managed to resolve the issue by updating jupyterlab. I dont know why it doesn’t come preinstalled with the latest version when I install the latest version of anaconda. Anyway thanks once again…

Probably, something I pointed out in another response yesterday might help you in considering this. And that is that JupyterLab is under very active development presently. As you saw version 2 is relatively new. Anaconda often is about offering a stable package that works best in the full management system and what gets installed may not be the latest and greatest for that reason. There’s compromises.

In Version **3.5.0** , Settings → Advanced Settings Editor, select “Theme” in left navigator, then in User Preferences, make change for “ **code-font-size** ”.
