[Tex/LaTex] How to specify font size less than 10pt (or more than 12pt)

fontsize

I'm trying to make a document that has a very small font throughout, I tried this:

\documentclass[0.5mm, a4paper]{article}
\documentclass[7pt, a4paper]{article}

But it doesn't seem that they allow me to go anything below 10pt.

This hack make it work, but not for the section headers:

\fontsize{4mm}{5mm}\selectfont

Does anyone know any better ways to do this?

extsizes classes offer a base font size between 8 and 20 pt, you may choose the extarticle class
KOMA-Script classes support freely customizable base font sizes and you may specify them by any TeX length unit like pt, bp or mm, so you might use scrartcl.

I recommend to use a KOMA-Script class.

Constructing an answer from the comments:

Using the extsizes package:
```
\usepackage[9pt]{extsizes}
```

Using the scrextend package:

\usepackage{scrextend}
\changefontsizes[11pt]{9pt}

Using the anyfontsize package:

\usepackage{anyfontsize}
\fontsize{9}{11}
\selectfont

Also, use a scalable modern font which scales well to lower font sizes (eg: lmodern, kpfonts). However, in general, it is not recommended to not use such small font sizes in the interest of readability.

[Tex/LaTex] How to get the font sizes I need when they are in between the defaults? SAE Class progress

My solution to this problem was to first change the base class of my SAE class file from article to extarticle:

% The extarticle class allows for 9 pt font as the normalsize font.
\LoadClass[twocolumn,9pt]{extarticle}

This took care of most of the font sizes I needed, and allowed me to use a 9 pt. font as the \normalsize font in the document. For the fonts that were not available via the normal font size commands, I defined two additional font sizes in the following way:

% Define two additional exact font sizes to meet SAE guidelines. These font sizes are not included as part of the extarticle class, so we define them here. A 15pt font (baseline skip = 15*1.2 = 18), and an 11 pt font (baseline skip = 11*1.2 = 13.2). The general rule of thumb is that the baseline skip is 1.2 times the font point size. We will need to use \SAEtitlesize in the title definition, and SAEheadtwosize in the \subsection{} definition (heading level 2).
\newcommand\SAEtitlesize{\@setfontsize\SAEtitlesize{15pt}{18}}
\newcommand\SAEheadtwosize{\@setfontsize\SAEtwohead{11pt}{13.2}}

% A note about font sizes in this class: The class is based off the extarticle class, which supports 8-20pt font sizes as the default. Here we select 9pt fonts as the default \normalsize font. Thus in the SAE document class you will get the following font point sizes for each latex fontsize command:

% \tiny:         5 pt
% \scriptsize:   6 pt. 
% \footnotesize: 7 pt. SAE asks that text inside tables is 7 pt. Use \footnotesize before tables for this.
% \small:        8 pt. SAE asks for caption fonts to be 8 pt. Use \small for captions.
% \normalsize   9 pt. This should be the standard fontsize for the text body, as well as for 4th level headings (in bold/italic). This should also be the size of the paper number at the top of the page (in bold), and the size of the nomenclature/definitions/abbreviations at the end of the paper.
% \large        10 pt. This should be the size of 3rd level headings (in bold, \subsubsection{}), and the affiliations
% \Large        10.95 pt. 
% \SAEheadtwosize 11 pt. This custom font size should be the size of Heading level 2 (subsection{})
% \LARGE        12 pt. This should be the size of the author list (in bold), and all 1st level headings (in bold), including abstract, introduction, body headings, summary, references, contact info, acknowledgements, definitions/abbreviations, and the appendix heading.
% \huge         14.4 pt. 
% \SAEtitlesize 15 pt. This custom font size should be the size of the title.
% \Huge         17.28 pt.
