Ruler Bar works well in my environment (mostly text-only messages, others not tested yet), but I had to play around with the settings (e.g. scale of marks) quite a bit to make it exact for my font (Lucida Console, 11 px) - 135%, by the way.

I would suggest to improve the add-on in a way which enables automatic calculation of fixed font widths.
