I would like to change text files font in Quick Look on OSX.

Tried to find answers on support forums but found none.

    AFAICT this is not possible with the default QuickLook plugin for text files. What should be possible is using a different one that generates formatted HTML previews of text files. Maybe something like this already exists, I haven't found it yet though. – Daniel Beck Dec 31 '13 at 01:37

You will not be able to change the size of the font directly in the pop up (discussed here), but you can change the size of the pop up box to make the text larger and easier to ready. @Howie in an answer to a Super User question did a great job at explaining how to do this:

From Ars Technica Forum, courtesy of username DarylF2:

I figured it out, and is was actually pretty simple.

Show the package contents for "/Library/QuickLook/iWork.qlgenerator/" and edit "/Library/QuickLook/iWork.qlgenerator/Contents/Info.plist".

Change the "QLPreviewHeight" parameter value from "600" to your new value (I used "1000") and change the "QLPreviewWidth" parameter value from "800" to your new value (I used"1333").

That's it.

I didn't need to reboot or even log out and log back in for this to take effect, but I did need to open a few Pages document Quick Look previews before it seem to "take".

As always, back up the original file first and realize you are editing a file Apple didn't intend for the end user to edit.

I just tested it and it works for iWork documents only. PDF and other types of previews aren't affected. I'll try to see if there is more to it than that.
