I seek to make a poster on Beamerposter that is printable on a 36" high x 48" wide laminated poster. I found samples on previous discussions in the site but I would like to be able to verify that they are indeed in the right dimensions.
Specifically, consider this template. Is this 36" x 48". It sure looks like it to me but I don't know how to verify. Also, can I make the two middle columns into one column instead (so 3 columns instead of 4)? Thanks!
