frame size beamer [closed]

Question

I am using beamer to create a simple presentation. I want to be able to set the width and height of all frames with respect to the slide size? Then I also would like to change the margin between columns, so that I make use of space more efficiently.

working example:

\documentclass{beamer}
\usepackage{times}
\usepackage{amssymb,amstext,amsmath,latexsym,mathtools}
\usepackage[italian,british]{babel}
\usepackage[T1]{fontenc}
\usepackage{csquotes}
\usepackage[style=authoryear-comp,firstinits=true,maxcitenames=2,maxbibnames=99]{biblatex}
\usepackage{cmbright}
\usepackage{setspace}
\usepackage{hyperref}
\usepackage{xcolor}

\usepackage{geometry}
\geometry{verbose}
\usepackage{movie15}


\begin{document}


\begin{frame}
\frametitle{abc}
abc
\begin{columns}[c]
\column{1.2in}
\framebox{\includegraphics[width=\linewidth]{fig.pdf}}\\
abc\\
\column{1.2in}
\framebox{\includegraphics[width=\linewidth]{fig.pdf}}\\
abc\\
\column{1.2in}
abc\\
\end{columns}
\end{frame}

\end{document}

Answer 1

Use fractions of \linewidth to fix the width of your columns. ex: \column{.3\linewidth} for each of three columns. The margins between the columns share the rest (.1\linewidth). If the margins of the slide itself are not fixed, use fractions of \paperwidth to fix the width of your columns.
