The forum post you linked to is from two years ago. Graphene now has a built-in theme option to change the width:
Graphene Theme Options >> Display Options >> Column Width Options
Also, there is no need to use a custom css plugin, as Graphene has supported that feature for a long time:
Graphene Theme Options >> Display Options >> Custom CSS
That is always your best bet. You can read more about how to do that (even after you’ve made changes) in the post I’ve written here:

I don’t see anything wrong with your site now, other than the advert on the right side is too wide and you’ve added nothing to the left-hand widget area.
