Increase default note width when popped out

Things I have tried

I’ve tried researching the help on this subject and also Google searching, without any luck.

What I’m trying to do

I simply want to increase the default width of the note when it is popped out into its own window. It is too thin at present. I cannot see any setting for this. Does one exist? If not, is there a simple CSS hack that can fix this? I am using the Nord theme.
