Posters (beamerposter/tikzposter/a0poster)

A conference poster is one enormous A0/A1 page — a title banner (title, authors, affiliation, logos) on top, then blocks arranged in columns below. LaTeX offers several options — beamerposter (reuse beamer), tikzposter (a modern TikZ-based class), and the bare-bones a0poster or box-based baposter. This page helps you pick.

How posters work

A poster is one giant sheet (A0 ≈ 84×119 cm), read from a distance. So the basic shape is large fonts, a title banner, and titled blocks arranged in columns. The class handles the paper size and font scaling; you place the blocks into columns.

beamerposter — reuse beamer

If you know beamer, beamerposter is the quick path. Layer beamerposter on the beamer class and set size, scale, and orientation. You reuse beamer’s block, columns, and themes at poster scale, with familiar syntax.

latex
\documentclass[final]{beamer}
\usepackage[size=a0,scale=1.4,orientation=portrait]{beamerposter}
\begin{document}
\begin{frame}{}
  \begin{columns}
    \column{0.5\textwidth}
      \begin{block}{はじめに} 本文。 \end{block}
  \end{columns}
\end{frame}
\end{document}

tikzposter — a modern dedicated class

tikzposter is a dedicated class built on TikZ, with attractive defaults. Declare something like \documentclass[25pt,a0paper,portrait]{tikzposter}, write content with \block{title}{body}, and arrange the blocks in columns. \usetheme{Board} (plus color styles) restyles the decorated boxes. A go-to when you want it to look polished.

latex
\documentclass[25pt,a0paper,portrait,margin=10mm]{tikzposter}
\usetheme{Board}
\begin{document}
\maketitle
\block{はじめに}{ここに本文。}
\end{document}

a0poster / baposter — bare-bones / box-based

a0poster is the original, minimal class: it just sets A0 paper and scaled fonts — you lay things out yourself with multicol or minipage (beamerposter is built on it). baposter is organized around a grid of boxes that auto-align and resize, with color schemes. Both work, but tikzposter/beamerposter are more common today.

  • You know beamer → beamerposter.
  • Polished, fast → tikzposter.
  • Minimal, hand-laid → a0poster.
  • A grid of boxes → baposter.
