ePoster Template You can use this template for creating your ePoster, or use it as a guide. The format for ePosters is “wide screen” or 16:9. Please do not change the size or format. Use only one slide – no additional slides will be allowed. When you add images, make sure that they are  large enough to be displayed without pixelation.  Larger images are better if you want visitors to be able to zoom in on them. They should be least 960 pixels wide. Do not scale images past 100%. If you want an a background image for your whole slide,  it must be at least 1920x1080 pixels. When you’re done, export the poster as a PDF and submit.
