We are preparing an e-poster and a printed poster for poster presentation at a conference. The organizer define the dimension of the poster as follows (everything is prepared in .pptx format and then exported to .pdf):
- poster size in pixel: 1536px x 1080px
- poster size in cm: 54.2cm x 38.1cm
How is this not a contradiction? Both "sizes" have the same aspect ratio but the actual sizes differ. The px-size translates to roughly 40.64cm x 28.56cm which is significantly smaller. A quick google search revealed that indeed a lot of congress organizer (like here or here) request the exact same dimension as stated above and I really wonder why? Isn't this something which will definitely lead to different printed poster sizes or am I missing something?
