Design your Poster the same way you would design it for printing it for a poster hall. Instead of printing your poster, a PDF file of your poster is loaded into the platform, turning it into an ePoster. If your organizer requests a virtual poster (ePoster with an audio explanation), prepare your explanation on paper and practice speaking it out loud. You can then record the audio during the PDF upload process. Your organizer will provide you with more information how long your audio explanation should be. 

Whichever tool you use, ensure that your resolution is set to 72dpi (standard for screen resolution). 

Generally, for print, posters are suggested to be designed at 36" high by 48" wide or  91.4 cm high x 121.9 cm wide. This matches a 3:4 screen ratio. 

Many new devices and modern laptop screens have a wider screen with a 16:9 ratio. This would match a 36" high by 64" wide size. You can also use this size if you know that you do not need to print at all. 

Limit the content to the essentials and include up to 4 images and up to 3 charts. Viewers of your ePoster or virtual poster can zoom in and move it on their screen to view different areas of interest. Ensure to include a link and/or your email address to easily contact you. When adding links, use link shorteners such as This allows you to save text space and it makes it easy for anyone to copy it.  

You can use simple tools like Google Slides or Microsoft PowerPoint to design your Poster. In these tools, create a single slide and set the slide size correctly. Avoid animations, video, or interactivity as the ePoster is displayed for viewing, just like your printed poster in a normal poster hall.
