# Setting exact margins

I am writing a document for which I need the margin to be exactly as follows: left, right, top and bottom text margin all equal to 1in, distance from bottom of the paper to page number equal to 0.75in (I don't have any footnote or header to set).

I tried to use the fullpage package in LaTeX but it does not give me the 0.75in to the page number. Is there a way to force that? I tried to set manually the margins for a 8.5x11 paper but I am not succeeding.

I tried but after writing:

\documentclass[PhD]{class_file}
\usepackage[margin=1in,footskip=0.25in]{geometry}


I get the error message \paperwidth (0.0pt) too short.

I don't see the \paperwidth is set to 0.0pt anywhere though..

Also it seems to me that depending on which machine I use to compile my tex file, I get different margins, even when I set them up manually (without using geometry). Is it possible?

Using the geometry package things seem to work a bit better now (I changed machine and the problem with the paper width previously mentioned disappeared).

\usepackage[margin=1in,footskip=0.25in]{geometry}


gives me without problem upper, right and left margin of 1in. But the lower margin is 1.2in and I can't change it to be 1in even by using bottom=1in or bottom=0.8in. I really don't see how this can happen. Maybe a problem with the spacing between lines? The class files I am using can be fund at http://www.math.ucla.edu/help/tex/uclathes/

I erased the margin settings of uclath12.clo as the margin I need are different from the ones that this file gives. Thank you.

You should try the geometry package. For example \usepackage[margin=1in]{geometry} provides a left/right/top/bottom margin of 1in. – Werner Feb 29 '12 at 0:19
Please provide class_file.cls if you're allowed. – rdhs Feb 29 '12 at 17:05

You can use geometry package.

\documentclass[12pt,english]{article}
\usepackage[a4paper,bindingoffset=0.2in,left=1in,right=1in,top=1in,bottom=1in,footskip=.25in]{geometry}
\usepackage{blindtext}

%In the middle if you want to change the margins use
{\newgeometry{left=0.8in,right=0.8in,top=1in,bottom=1in}

%to restore old margins, use

Expanding on Werner's comment, to get the page number's baseline 0.75 in above the page's bottom edge, use footskip:

\documentclass[letterpaper]{article}
\usepackage[margin=1in,footskip=0.25in]{geometry}

\begin{document}
Lipsum
\end{document}
