# How to reduce the margins

I am making a report using latex, it is looking fine but there is a really large space taken up by the margins. Here is the main tex file

\documentclass[fontsize=13pt]{scrreprt}
\usepackage[pdftex]{graphicx}
\usepackage{color}
\usepackage{gensymb}
\usepackage{mathtools}
\usepackage{fancyhdr}

%%    homebrew commands -- to save typing
\newcommand{\HRule}{\rule{\linewidth}{0.5mm}}
\def\onequarter{\frac{1}{4}}
\pagestyle{fancy}
% New colors

\definecolor{orange}{RGB}{255,127,0}

\begin{document}
\input{./title.tex}
\input{./cert.tex}
\input{./ack.tex}

\tableofcontents
\input{./intro.tex}
\input{./learn.tex}
\input{./comp_list.tex}
\input{./comp_desc.tex}
\input{./block.tex}
\input{./ckt_dia.tex}

How may I reduce the margin to maybe half of what it is right now?

These "larger margins" are good typography. Please read the documentation for koma-script. –  Martin Schröder Oct 19 '11 at 21:37

The easiest way is perhaps to use the DIV=<value> option for the document class, see table 2.1 in section 2.6 Options and Macros to Influence the Page Layout in the (English version of) the KOMA-script manual (dated 2013-12-19). You can choose integers from 6 to 16, where larger numbers give a larger type area, i.e. smaller margins.

For example

\documentclass[fontsize=13pt,DIV=14]{scrreprt}


Browsing the manual, I also see that you can set the type area with

\areaset[BCOR]{Width}{Height}


where BCOR is binding correction. Read chapter 2 Construction of the page layout with typearea of KOMA script's manual for more information.

Options and Macros to Influence the Page Layout can now be found in section 2.6. The German title is Einstellung des Satzspiegels und der Seitenaufteilung. –  ComFreek Aug 5 '14 at 10:58
@ComFreek Thanks, I edited my answer slightly. –  Torbjørn T. Aug 5 '14 at 11:28

You can use the geometry package to easily change the margins:

\usepackage[top=tlength, bottom=blength, left=llength, right=rlength]{geometry}


Or

\usepackage[letterpaper]{geometry}


EDIT: For KOMA-Script, you should use the typearea package that is part of the bundle to change the page layout, not the geometry package. See Chapter 2 of the KOMA-Script Documentation

You can, but you shouldn't - the page layout done by koma-script is good typography. –  Martin Schröder Oct 20 '11 at 8:26
