A Couple of Reminders
You can design posters in Microsoft PowerPoint by changing the size of the slide to the dimensions of your printed poster. PowerPoint is installed on most campus computers and is available for both Windows and Mac.
You can also use Adobe Creative Suite products such as Illustrator, Photoshop, and InDesign.
Make sure you find out what file format is accepted for printing your poster. In some cases, you may need to export your finished poster as a .pdf.
Using graphics can be helpful on a poster because it breaks up the text and helps illustrate your points. Make sure the images you use are free from royalty and copyright. Below are some sites that offer royalty-free images. Most of these are either in the public domain or under a Creative Commons license, which allows you to reuse images for free as long as you credit the original creator.
