The a0poster class file is well suited for creating large posters. It is based on the article class file, but uses large paper sizes and large fonts. The following class options govern the paper size and orientation:
| landscape | landscape (default) |
| portrait | portrait |
| a0b | "DIN A0 big" (default) |
| a0 | DIN A0 |
| a1 | DIN A1 |
| a2 | DIN A2 |
| a3 | DIN A3 |
The available font sizes and their declarations are shown in Table 1. You will need to make sure you use scalable fonts, as the standard Computer Modern fonts won't be available in large sizes. For the Times/Helvetica/Courier combination, use the mathptmx, helvet and courier packages:
\usepackage{mathptmx}
\usepackage[scaled=.90]{helvet}
\usepackage{courier}
