# Dose .eps graph has fixed size? so \includegraphics[scale=0.7]{foo.eps} means 0.7 of that size

An .eps graph is too large to fit in a two column article. So I have to increase the font in the graph, and scale it down, otherwise the font is too small to see.

I am thinking if the .eps graph has fixed size, then I can change that size and don't need to increase font and scale down.

David Carlisle gave a good answer. As a sidenote, your thinking is correct. – mvkorpel Jun 28 '14 at 17:34
