# How to make a figure span on two columns in a scientific paper?

If I just try to set the figure's size to 0.9\textwidth my figure will just end up on the right column, sized to be two-columns wide.

Has anyone done this before?

I think we need a minimal example of what you are doing. There are lots of possible variations here. Did you try \begin{figure*}, for example? –  Joseph Wright Sep 16 '10 at 21:05
That's exactly what I was looking for, thanks. I thought adding an * only removed the figure's numbering? –  levesque Sep 16 '10 at 21:07
You're confused with equation* –  Will Robertson Sep 16 '10 at 22:51
figure* and table* are two column figures and tables, respectively. –  TH. Sep 16 '10 at 23:52
I had a similar problem, in \documentclass[twocolumn]{article}--but using figure*[width=\textwidth] sends it to the bottom of the document, not breaking the columns. –  isomorphismes Jun 3 at 9:17
