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


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:


Does anyone know any better ways to do this?

Best Answer

  • 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.
