\BeginIndex{}{font>size}

The main document font size is one of the basic decisions for the document
layout. The maximum width of the text area, and therefore splitting the page
into text area and margins, depends on the font size as stated in
\autoref{cha:typearea}. The main document font will be used for most 
of the text. All font variations either in mode, weight, declination, or size
should relate to the main document font.


\begin{Declaration}
  \KOption{fontsize}\PName{size}
\end{Declaration}
\BeginIndex{Option}{fontsize~=\PName{size}}%
In contrast to the standard classes and most other classes that provide only
a very limited number of font sizes, the \KOMAScript{} classes offer the
feature of selection of any desired \PName{size} for the main document
font. In this context, any well known \TeX{} unit of measure may be used and
using a number without unit of measure means \PValue{pt}.\iffree{}{ More
  information about font size selection for experts and interested users may
  be found in \autoref{sec:maincls-experts.addInfos},
  \autopageref{desc:maincls-experts.option.fontsize}.}

If you use this option inside the document, the main document font size and
all dependent sizes will change from this point. This may be useful, e.\,g.,
if \IfCommon{maincls}{the appendix }%
\IfCommon{scrlttr2}{one more letter }%
\IfCommon{scrextend}{the appendix }%
should be set using smaller fonts on the whole. It should be noted that
changing the main font size does not result in an automatic recalculation of
type area and margins (see \Macro{recalctypearea}\IndexCmd{recalctypearea},
\autoref{sec:typearea.options},
\autopageref{desc:typearea.cmd.recalctypearea}). On the other hand, each
recalculation of type area and margins will be done on the basis of the
current main font size. The effects of changing the main font size to other
additionally loaded packages or the used document class depend on those
packages and the class. This may even result in error messages or typesetting
errors, which cannot be considered a fault of \KOMAScript, and even the
\KOMAScript{} classes do not change all lenghts if the main font size
changes after loading the class.

This\textnote{Attention!} option is not intended to be a substitution for
\Macro{fontsize} (see \cite{latex:fntguide}). Also, you should not use it
instead of one of the main font depending font size commands \Macro{tiny} up
to \Macro{Huge}!%
\IfCommon{scrlttr2}{ Default at \Class{scrlttr2} is
  \OptionValue{fontsize}{12pt}.}
