# spacing between paragraphs in beamer

Is there any way to increase spacing between paragraphs in beamer without doing it manually in each paragraph?

I don't want to write \medskip, or other command manually all time (ok, if there's no choice I will, but...)

I also tried with \setlength{\parskip}{number of mm} in the preamble. That seemed nice to me but nothing happened.

And I don't want to itemize all my documents.

So, any suggestions? Thanks!

EDIT: Here there's a sample code. I used \setlength{\parskip}{8mm} in preamble and it doesn't work. Also tried moving it just after begin{document}.

\documentclass{beamer}
\usetheme{AnnArbor}
\usecolortheme{crane}
\usepackage[spanish]{babel}
\title{Title}
\author {MyName}
\institute{MyInstitute}
\date {\today}
\newtheorem{defi}{Definici\'on}
\newtheorem{ejem}{Ejemplo}
\newtheorem{teo}{Teorema}
\newtheorem{lema}{Lema}
\newtheorem{coro}{Corolario}

\setlength{\parskip}{8mm}

\AtBeginSection[]
{
\begin{frame}
\tableofcontents[currentsection]
\end{frame}
}

\begin{document}
\begin{frame}{Contents}
\tableofcontents

\end{frame}

\section{Testing}

\begin{frame}

hello world\\

bye world\\
\end{frame}
\end{document}

• \parskip is the correct approach. Try to give the number including a unit, e.g. \setlength{\parskip}{2cm} – samcarter is at topanswers.xyz Jul 4 '16 at 17:45
• If \setlength{\parskip}{<len>} doesn't work in your preamble, please provide us with something that replicates your behaviour. You must be doing something different. As a last resort, attempt putting \setlength{\parskip}{<len>} just after \begin{document}. – Werner Jul 4 '16 at 18:02

The problem is, that you are using \\. If you want a new paragraph use an empty line (or in the few occasions, this is not an option use \par)
\begin{frame}
