# How to write a Thesis with font of size 14pt? [duplicate]

I want to write my thesis in latex, with a font of size 14pt. I wrote

\documentclass[14pt,oneside,a4papper]{book}


but the font is not of 14pt. Can someone tell me how can I write with 14pt? Thank you!

• memoir suport 14 pt fonts. Beside this it also has many other features which can be handy ... – Zarko Jun 19 '17 at 20:04
• @Huang_d if I try to use extsize package, it tells me that "MiKTeX encountered an internal error." – g.pomegranate Jun 19 '17 at 20:07
• @g.pomegranate Great! I then suggest you to ask a new question about this specific issue. Please remember to add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – ebosi Jun 19 '17 at 22:12

The book class supports only 10, 11, and 12pt sizes. You need the extbook to be able to use 14pt. Better options exist, like scrbook or the memoir class, both support 14pt size out of the box.

\documentclass[14pt,oneside,a4paper]{extbook}
\usepackage{geometry}

\begin{document}

some text here ..

\end{document}
