I use the "slides" class to get full size equations for a presentation. (Yes, it needs to be in Powerpoint ;) )

However, I want to have the standard math font (like in the article class). There seems to be no option like serif for the beamer class. The reason, I'm not using the beamer class is that I get a "picture" just the size of my equation in Powerpoint with the slides class. With beamer or article, I get a bigger "picture" with a lot of white space around my equation.

Minimum example:


  • 3
    It seems that you want to use the standalone class instead of slides. – jub0bs Dec 9 '13 at 20:44
  • That does work, indeed. Could it be, that the slides class just has a default \begin{huge} ... \end{huge} in it? Seems like the symbols are about that size. Thanks for the hint :) – Bazi Dec 10 '13 at 7:15
  • Try pdfscreen. I like to use a 4.5" by 6" for 3x4 screens, or 4.5" by 8" for 9x16 wide screen. – John Kormylo Dec 10 '13 at 14:57
  • To get equation numbers with standalone, use parbox to set the width. – John Kormylo Dec 12 '13 at 21:25

I just followed egreg's lead in his answer at What are all the font styles I can use in math mode?, which indicated how the LaTeX kernel sets up math fonts.

\DeclareSymbolFontAlphabet{\mathrm}    {operators}
\DeclareSymbolFontAlphabet{\mathcal}   {symbols}
\DeclareMathAlphabet      {\mathbf}{OT1}{cmr}{bx}{n}
\DeclareMathAlphabet      {\mathsf}{OT1}{cmss}{m}{n}
\DeclareMathAlphabet      {\mathit}{OT1}{cmr}{m}{it}
\DeclareMathAlphabet      {\mathtt}{OT1}{cmtt}{m}{n}

\DeclareSymbolFont{operators}   {OT1}{cmr} {m}{n}
\DeclareSymbolFont{letters}     {OML}{cmm} {m}{it}
\DeclareSymbolFont{symbols}     {OMS}{cmsy}{m}{n}

y = mx + b ~~~\omega\Omega \mathbf{\Omega}\mathit{\Omega}

Note: equation also has margins, so you really can't get much smaller.


\backgroundcolor{lightgray}% to show margins

A = \pi r^2
