# Add a 3mm margin to every side of an A4 document [duplicate]

I have created a document in LaTeX and the document is complete, but the printers have asked for a 3mm white board applied to the PDF, so the overall size is 6mm wider and taller than standard A4.

How would I do this?

I found a similar question but this is for A5 paper instead: Add a 3mm margin to every side of an A5 document

\documentclass[a4paper, twoside, 12pt, hidelinks, final]{article}

\usepackage[top=1in, bottom=1in, left=0.75in, right=0.75in, headheight=35.4pt, footskip=35.4pt]{geometry}

\begin{document}

\clearpage\mbox{}\clearpage

\end{document}

• @Niklas Much appreciated! That looks like something I could work with and achieve what I am after possibly. – AeroMaxx Aug 13 at 15:10
