In the “Print Mode”, under “Printer”, I specified US Letter size under page setup. However, when I go to “Graphics” and export, I get a document that is sized A4. I would like my PDF to be in US letter size. Does anyone know how this can be fixed?
Welcome to the forum, Almond.
When exporting “normal” jobs (as opposed to booklet/spreads etc.) the page size in the right panel of Print mode is greyed out - this page size is not used. You need to set the appropriate page size in Layout Options > Page Setup. One of the reasons for this is that the list of paper sizes in Print mode is pulled from your connected printer; it may be that sometimes you want to export a PDF at a larger size than your printer can actually handle.
