I need to make an A3 poster in Latex and I have seen a lot of A0 poster templates, but when I try to set the A3 size the font is huge. Any A3 poster template? or which is the best package to use?

  • can't you set the normal font size as well? which class you intend to use? A minimal example would help. Jun 7, 2015 at 12:40
  • I am trying to use this template: latextemplates.com/template/a0poster-portrait-poster which uses \documentclass[a0,portrait]{a0poster} but when I change it to a3, the writing size is huge @thewaywewalk.

  • all the A series paper is the same aspect ratio so you can design to A0 or A4 or whatever's convenient and just print to A3. Jun 7, 2015 at 13:01
  • Besides increasing the font size, what exactly poster class do for you? Does it really serve any useful function? Jun 7, 2015 at 15:22
  • @DavidCarlisle Want to make that an answer?

I admit it's a workaround to your problem, but I always resized my posters later with gs, in case I needed it PDF resizing with ghostscript.
