Frequently asked questions
What size should a conference poster be?
The most common are 36×48 inches (landscape) and 48×36 (portrait) in the US, and A0/A1/A2 in Europe. We host 36×48, 48×36 and A2 templates so you can match your conference's spec.
Which LaTeX package makes posters?
Our templates use tikz and a poster-style column layout so text stays crisp at print resolution — no blurriness when you scale up, unlike raster tools.
Is there a tri-fold poster template?
Yes — our tri-fold academic poster template splits into three panels for a portable, table-top display.
Do I need to install LaTeX?
No — open any template on LetX and it compiles in your browser in seconds, on any operating system.
Can co-authors edit a poster together?
Yes — LetX supports real-time collaboration, and your unpublished work is never used to train AI.
