[Tex/LaTex] Tikzposter – Text Size

fontsizetikzposter

So, I have to create a poster (unfortunately) and of course use my favourite tool LaTeX – but here is where it gets problematic:

How does text or typeset size in TikZposter work – because it makes no sense to me…

So let me elaborate:
I use a0paper – and just start writing stuff.
If I use 12pt, I can fit what seems a reasonable amount of text on it (for A0) – and trying to compare it with plots sized explicitly (say 10cm wide) suggests this would be a an OK size (about twice the height I would expect from 12pt on normal A4 paper). But then the point measurement makes no sense – that is supposed to be absolute??

If I use 25pt or similar (because typeset on a poster should be large) the amount of text that fits on the poster is miniscule – which feels wrong given how large A0 is…

The PDF is sized correctly when I look at the milimetre measurements – so that seems OK, but zooming in to 100% gives me maybe half the size it should be on my laptop… (100% is maybe 40cm wide when A0 would be 89cm wide in portrait mode)

*So, how do the point sizes in TikZposter work?

Should I maybe use a different poster class? (assuming they are easier to work with)*

The most basic example for creating a poster:

\documentclass[a0paper,25pt]{tikzposter}

\begin{document}
\maketitle

\block{Background and Motivation}{
A test poster regarding text size. There is no space here for nay reasonable explanation of content...
}

\begin{columns}
\column{0.3}
\block{}
{
Especially with 3 columns there is no horizontal space for content... - this is width 0.3
}
\end{columns}

\end{document}

Once on uses 3 columns, suddenly a single sentence won't fit into it any more…

Best Answer

A0 is as wide as 4 A4-papers. So your column is more or less as wide as an standard A4 paper.

You can try out the fontsize in A4:

\documentclass[12pt]{scrartcl}
\usepackage{lmodern}
\begin{document}
Especially with 3 columns there is no horiEspecially with 3 columns there is no hori

\fontsize{25pt}{30pt}\selectfont Especially with 3 columns there is no hori
\end{document}

enter image description here

On A4 a 12pt font is okay, if you have only one column, with 2 columns it will imho be a bit to large. This means that on A0 a 25pt font (~ double size than 12pt) is okay if used in columns which use a size from 0.5 to 0.35 of the textwidth but can be too large if the columns gets significally smaller.
