# Why is my left margin slightly larger than my right margin

I've noticed that my left margin is slightly larger than my right margin while making a document. Here's an MWE of what I'm describing:

\documentclass[11pt]{article}

\usepackage[
showframe,
marginparwidth=0cm,
marginparsep=0cm,
margin=0.75in]{geometry}

\begin{document}
\begin{center}
\Huge lallalalalalal\\
\end{center}
\end{document}


And here's an image of the rendered PDF output:

Is there any way to make the left and right margins perfectly equal? I'm using LuaLaTeX.

• I don't see the difference with your MWE, compiled with pdflatex from texlive2016. Feb 20, 2017 at 18:14
• Your margin length settings can be combined into a single margin=0.75in.

• Remember to pass also the paper format, probably you want paper=letter. Feb 20, 2017 at 18:22
• @samcarter I used lualatex to compile this document which has this problem. You're right, pdflatex displays the document properly. Feb 20, 2017 at 18:43

The fix is to add a \RequirePackage{luatex85} to the preamble of the document, which fixes the margins and gives the expected output.
