# Line spacing in report [closed]

I need your help. I'm using this command:

\renewcommand{\baselinestretch}{1.5}
\normalsize

to create a spacing between the lines. But I'm still not sure where to insert it, wether before the begin{document} or after or before each text? Because there is one paragraph in the four pages I wrote till now, where there is no line spacing and I don't know why. Or do you know another command which would apply for the whole text? A package probably?

My code:

\documentclass[10pt]{report}
\usepackage[utf8]{inputenc}
\usepackage{titlesec}
\usepackage[left=35mm,right=35mm,top=35mm,bottom=35mm]{geometry}
\titleformat{\section}{\Huge\bfseries}{\thesection}{1em}{}
\titleformat{\chapter}{\huge\bfseries}{\thesection}{1em}{}
\titlespacing*{\section}{0pt}{3.5ex plus 1ex minus .2ex}{8.3ex plus .2ex}
\titlespacing*{\chapter}{0pt}{3.5cm}{2cm}
\begin{document}

\chapter*{Kapitel1}

\section*{Einleitung}

\subsection*{1.1 Motivation}

See the package setspace. –  Marco Daniel May 12 '13 at 12:49
@MarcoDaniel thank you Marco, I think you have to insert this: \usepackage{setspace} \onehalfspacing But it is still not working. –  abdu May 12 '13 at 12:56
Please show us an mwe. I am sure that it works. –  Marco Daniel May 12 '13 at 13:02
@abdu A tip: If you indent lines by 4 spaces or enclose words in backticks , they'll be marked as code, as can be seen in my edit. You can also highlight the code and click the "code" button (with {} on it). — Only inline markup () works in comments. –  Qrrbrbirlbel May 12 '13 at 13:26
@Qrrbrbirlbel ok thanks! –  abdu May 12 '13 at 13:36
