beamerposter 的文本缩放

Question

我正在使用 beamerposter 包为会议制作海报。我制作了自己的样式文件。但是，我无法确定海报的正确缩放比例是多少才能看得清楚。考虑到比例以及我使用 12pt beamer 字体大小作为基本字体大小的事实，我甚至无法理解“真实”字体大小是多少。

我阅读了以下问题的答案，但找不到答案。 Beamerposter比例参数、文字字体大小、标题字体大小。

我的 tex 文件中的相关行是

\documentclass[final,12pt]{beamer}
\usetheme{mystyle}   %The style is an adaptation of I6pd2 style
\usepackage[size=custom,width=240,height=120,scale=2]{beamerposter}
\usepackage[absolute,overlay]{textpos}
\usepackage{verbatim}
\usepackage[english]{babel}
\usepackage{amsmath,amsthm, amssymb, latexsym}
\usepackage[latin1]{inputenc}
\title{\Huge  Best Poster Ever!}
\author{Me\inst{1},- Someone else\inst{2}}
\institute{
\inst{1} INST1 \qquad
\inst{2}  INST2}
\begin{document}
\begin{frame}
\begin{textblock}{3.5}(0.1,3)
\begin{block}{\Large Introduction}
This is going to be a great poster, once I'll figure out the best scaling for text size!
\end{block}
\end{textblock}
\end{frame}
\end{document}
