I want to make a poster using the a0poster package. I want to modify the text margins, so the text should be wider. I'm using boxes in a portrait, three column poster, but I have problem trying to get boxes bigger (one white page and after the text). Thanks

  • No results modifying the value of \textwidth? – karlkoeller Jun 28 '13 at 16:07
  • I mean something like \addtolength{\textwidth}{1cm} – karlkoeller Jun 28 '13 at 16:17
  • Done!..thanks!..I was thinking taht could be more difficult (change the .cls file or something). Thanks again! – Alejandro Guarnizo Jun 28 '13 at 16:45

You can simply increase the width of the text in the page adding the line:


If 1cm is not enough or too much, change it to your needs.

  • Done!!..thank you...I was thinking that in that a0poster class I will need to modify the .cls file. Thanks again! – Alejandro Guarnizo Jun 28 '13 at 17:03
  • There is one inconvenient in this answer, it only reduces the right margin, due to the longer lines. The left margin remains the same. – fccoelho Aug 13 at 16:32
