- When you create your document in PowerPoint (instructions), Publisher, or another program, use the Page Layout function to make the dimensions of the electronic document conform to the size of the final poster you want before you begin to put in any text or other elements.
- Making posters smaller or larger after they've been designed causes formatting problems and pixellated or unclear images.
- In PowerPoint, change the "Slides sized for" to "Custom".
- One dimension must be 40 inches or less. This is due to the size of the poster paper. The other dimension can be smaller or larger, depending on your needs and how much paper is left in the printer.
- Please note: PowerPoint will not allow you to create a poster larger than 56" on one side.
- We recommend using Microsoft Publisher for creating posters that will be larger than 56 inches on any one side.
- Publisher will suggest that you use a template. You can start with one of the "Blank sizes" in the "Signs" category (look for one that is 36" on one side), or you can choose "More Blank Page Sizes" and choose "Create new page size" under the Custom heading.
- Publisher is not available on the Mac OS, but can be accessed via CloudPC (more information).
The most common poster size we see is 20" wide by 30" tall. A poster of this size, rotated correctly at printing, costs $8.33.
