Set fontsize of 14pt in article class

articleclass-optionsfontsize

I would like to set the fontsize of 14pt in the article class. But, using What point (pt) font size are \Large etc.?, I obtain:

Questions:

I am assuming that the output means that the closest font size available is 14.4pt. Why did the font size not default to 12pt or 14.4pt instead of 10pt?
How do I set the font size to 14.4pt. Using \documentclass[14.4pt]{article} yields identical output as above.

Best Answer

To use the article document class with a basic font size of 14pt (14.4pt for sticklers for detail), you should run

\documentclass[14pt]{extarticle}

There's also extreport and extbook. These three document classes provide the following extra font size options (other than the usual 10pt, 11pt, and 12pt, of course): 8pt, 9pt, 14pt, 17pt, and 20pt.

[Tex/LaTex] Change font size of \Large etc.

The size for article.cls with option 11pt are declared in size11.clo. You can copy the definitions and change them. E.g. the original \Large is setup like this:

\newcommand\Large{\@setfontsize\Large\@xivpt{18}}

So use in your preamble (or a local sty).

\makeatletter %only needed in preamble
\renewcommand\Large{\@setfontsize\Large{13pt}{18}}
\makeatother

The 18 is the baselineskip (in pt). Adjust it to the value you want to use.

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}
