# Changing the font size with \emph

In the .tex document I created, the emphasis command \emph{text} is frequently used (note that I use \documentclass{llncs} ). However, the .pdf preview shows the emphasized text as smaller that the plain text. What would be the way to change the font size for the text in \emph{text}. I would be good if one is able to set the option at the beginning, and not change every occurrence of \emph{}.

• Please, show a minimal example. – egreg Apr 20 '12 at 8:51
• i have noticed italic text looking smaller, on occasion. the effect is never visible when i print out. have you checked how your stuff looks when printed? – wasteofspace Apr 20 '12 at 16:28
• No, I haven't. I'm surprised that there is that much to take into account with such a simple task. With huge in the answer below, the emph. text looks a lot bigger with Adobe. Your suggestion is that it would look normal when printed? – boy Apr 20 '12 at 20:16

You could use

\let\oldemph\emph
\renewcommand\emph[1]{{\huge\oldemph{#1}}}


For future reference (for other users), the llncs documentclass is available here

\documentclass{llncs}

\let\oldemph\emph
\renewcommand\emph[1]{{\huge\oldemph{#1}}}

\begin{document}

Here is some \emph{emphasized} text

\end{document}

• Thanks. This works, but the text is too large now. Which parameter. How could I specify the font size between normal and large? – boy Apr 20 '12 at 9:01
• @boy that's up to you! my pdf viewer shows the emphasized text as I would expect it. perhaps this is a viewer issue... – cmhughes Apr 20 '12 at 9:04
• @boy That's why I asked for a minimal example. The "problem" can be just related to the viewer. – egreg Apr 20 '12 at 10:00
• @boy, @cmhughes: This solution will break the use of \emph in the context of other fontsizes, \huge will be used everywhere, even if the surrounding font size is \tiny. On my system I don't have any problem with llncs + \emph. So before a solution a minimal example and the pdflatex log file is needed. – Ulrike Fischer Apr 20 '12 at 12:48
