[Tex/LaTex] reduce margins for documentclass book

Question

I am using documentclass book but want to shrink margins to 0.5 on each side and not have margin notes so the text can be wider. Is there any way to request that or is that not legal for a book?

Answer 1

This does not look really nice -- it's hard to read, but setting margin=0.5in generates small margins.

I don't recommend this.

\documentclass[a4paper]{book}

\usepackage[margin=0.5in,nomarginpar]{geometry}

\usepackage{blindtext}

\begin{document}
\blindtext[10]
\end{document}
