# Beamerposter scale parameter, text font size and title font size

I want to create a poster with `beamerposter` with pagesize 240cm (width) x 120cm (height) with two columns. Will the following line of code produce what I need?

``````\usepackage[size=custom,width=240,height=120,scale=1,debug]{beamerposter}
``````

If so, what does the `scale` option do? If I set it equal to `2` then will my font size and paper size double?

Secondly, I need to have the title font size of 10cm and text size of 5cm (with the title in the center). How can I code this?

Can anybody know how to change title and text font size of the following beamerposter template: robjhyndman.com/researchtips/beamer-poster. I have to set height of at least 10cm for title font. –  amir Apr 27 '12 at 13:25
I think this post has your answer. Check the solution. tex.stackexchange.com/questions/51556/… –  R. Schumacher Apr 27 '12 at 16:24

I am not very expert but recently I am also working with `beamer` to create a poster. The scale option is for your font size. Like I use

``````\documentclass[final, 12pt]{beamer}
\usepackage[size=custom,width=77,height=107,scale=1.4,orientation=portrait]{beamerposter}
``````

I choose scale size 1.4, then I choose `\Large` size for my title, so it will multiply by 1.4 than the usual font size (`\Large` in `12pt` Beamer is `16.24pt`). Now you have to calculate for your's one...

You can get the font sizes in wiki.

Scale tends to increase font, figures etc to completely fill the page. Here is something you might find useful:

``````\documentclass[final]{beamer}
\usepackage[scale=1.20]{beamerposter}
\newlength{\sepwid}
\newlength{\onecolwid}
\newlength{\twocolwid}
\newlength{\threecolwid}
\setlength{\paperwidth}{240cm}
\setlength{\paperheight}{120cm}
\setlength{\sepwid}{0.025\paperwidth}
\setlength{\onecolwid}{0.21875\paperwidth}
\setlength{\twocolwid}{0.4625\paperwidth}
\setlength{\threecolwid}{0.70625\paperwidth}
\setlength{\topmargin}{-1in}
\usetheme{confposter
``````
