I want to create a TeX document for which the first (summary) page is \documentclass[10pt]{article}, but for which the rest of the document is \documentclass[12pt]{article}. Is there an easy way to do this?
[Tex/LaTex] How to change font size mid document
fonts
Related Solutions
The exact configuration depends on the fncychap style you’re using, but in general, there are a few macros for adapting the style, as described in section 2.1 of the fncychap documentation. The ones for changing the font etc. are \ChNameVar{stuff}, \ChNumVar{stuff} and \ChTitleVar{stuff}. Here’s an example for the style Sonny using pdfLaTeX:
\documentclass[12pt]{report}
\usepackage{xcolor}
\usepackage[T1]{fontenc}
\usepackage[Sonny]{fncychap}
% defaults:
%\ChNameVar{\Large\sf}
%\ChNumVar{\Huge}
%\ChTitleVar{\Large\sf}
% custom:
\ChNameVar{\Large\fontfamily{put}\selectfont\color{blue}}
\ChNumVar{\Huge\fontfamily{pzc}\selectfont\color{red}}
\ChTitleVar{\Large\fontfamily{phv}\selectfont\scshape\color{green}}
\begin{document}
\chapter{Hello World!}
Foo bar baz
\end{document}
For some more details on how to change the font and also how to do it with XeLaTeX, LuaLaTeX, or ConTeXt, see How do I use a particular font for a small section of text in my document?.
Also note that in some fncychap styles, variables influence the following variables; e.g. in my example, “Hello World!” and the rules would be red if I hadn’t specified their color. I’m not sure if that’s a bug or intended behavior.
You're halfway there. The following code should do what your require. See the comments in my code for explanation.
\documentclass[12pt]{scrreprt}
% The "12pt" class option sets \normalsize to 12pt and \footnotesize to 10pt.
% If not modified, the font size in footnotes will correspond to \footnotesize.
\usepackage[a4paper, left=2.5cm, right=3cm, top=2.5cm, bottom=2.5cm]{geometry}
\usepackage{mathptmx} % loads Times New Roman
\usepackage{setspace} % for interline spacing
\onehalfspacing % interline spacing of 1.5 in main text, 1 in footnotes
\usepackage{lipsum} % dummy text
% Here, I redefine \tabular to automatically switch to
% \footnotesize within the scope of a tabular environment.
\let\oldtabular\tabular
\renewcommand{\tabular}{\footnotesize\oldtabular}
\begin{document}
\chapter{Foo bar}
An outline of intellectual rubbish%
\footnote{Man is a rational animal, so at least I have been told.
Throughout a long life, I have looked diligently for evidence
in favour of this statement, but so far,
I have not had the good fortune to come across it.%
}
\lipsum[1-5]
\begin{table}
\centering
\begin{tabular}{|c|c|c|}
\hline
hello & see ya & bye\\
\hline
\end{tabular}
\caption{Foobar}
\end{table}

You can change font size using
\fontsize{10}{12}\selectfont(the first number is the pt size of the font, the second number the space in pts between lines: this becomes the value of\baselineskip), but in general I think it's better to try using things like\tiny,\small,\scriptsize,\normalsize,\footnotesize,\large,\Large,\LARGE,\hugeand\Huge(and the corresponding environments (e.g.,\begin{small} ... \end{small}). I think\footnotesizewould give you a 10pt font in a document with 12pt set in its document class options.And if the summary page is done using a special environment, like
\begin{abstract} ... \end{abstract}likely what you want can be done a completely different way, such as by using the abstract package. (It's hard to give concrete advice without knowing more about the details of the summary page, however.)
