[Tex/LaTex] Is it possible to use 12 pt font size in the achemso package

achemsofontsize

I am typesetting a report using the achemso package, because it is required that my report be in American Chemical Society (ACS) format. However, I am not submitting to an ACS journal. It is required that my report be in 12 pt Times New Roman font with 1.5 line spacing. I think that achemso by default uses Times New Roman (that is what it looks like), and I can accomplish 1.5 line spacing with \onehalfspacing.

How can I accomplish 12 pt font size in achemso? I have tried:

\documentclass[12pt]{achemso}

But I get this warning/error:

LaTeX Warning: Unused global option(s):
[12pt].

Is there any way I can still use achemso and enforce 12 pt font size?

Best Answer

In a word, 'no'. The achemso class is intended purely to support submissions to the ACS, and so has no features which are not needed for that purpose. The achemso package is intended to support producing more general documents which need some of the features of the class. You should use a suitable general class (for example report) and load appropriate packages.

[Tex/LaTex] Scrbook: Using fallback calculation to setup font sizes

This message tells you that KOMA-Script has a problem with your given fontsize (see the answer of @cgnieder for the mechanism KOMA-Script uses).

Why do you not only use \documentclass[fontsize=12pt]{scrbook}? Then you can delete \KOMAoptions{fontsize=12pt} and \renewcommand*{\bibfont}{\normalfont\changefontsizes{12pt}}.

The low level commands to change the fontsize are for example

\fontsize{12pt}{14.5pt}\selectfont

or (depending on your font and standard fontsize!) you can use \large for 12 pt fontsize if you have a 11 pt standard font.

You can enclose titlepage, table of contence and bibliography with for example

{\fontsize{12pt}{14.5pt}\selectfont ...}

to change the standard font size only for the part ... .

But that is only a hack. I would oversee this astonishing rule and use 11 pt everywhere ...

You're halfway there. The following code should do what your require. See the comments in my code for explanation.

enter image description here

\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}
