When printing with PDF-XChange Editor, selecting “Fit to Printer Margins” as the type and enabling the “Select Paper Size by Document's Page Size” option will choose the largest paper size available that matches the document's aspect ratio.
The following verification uses a sample file set to a width of 264 mm and a height of 297 mm. This page size was intentionally designed to achieve an 8:9 width-to-height ratio based on the height of A4 paper (297 mm). This ratio allows the pages to be displayed without gaps when viewed in full-screen mode with two pages display mode on a 16:9 aspect ratio display.
Case A: When a paper size with the same aspect ratio as the page size exists
- First, register multiple custom forms with an aspect ratio of 8:9 in PDF-XChange Printer, as shown in the figure below.
Printing with this configuration selects the paper size closest to the page dimensions, #7 (280 x 315 mm), delivering the result the user expects.Code: Select all

Case B: When no paper size with the same aspect ratio as the page size exists
- Next, register multiple custom forms with an aspect ratio of 1:1 in PDF-XChange Printer, as shown in the figure below.
Although the aspect ratio of each custom form has changed from 8:9 to 1:1, they still retain the aspect ratio closest to the aspect ratio of the document's page size, so one of these custom forms will be automatically selected. However, when printing with this setting, for some reason the smallest size, #1 (40 x 40 mm), is selected. Even when limited to paper sizes with an aspect ratio of 1:1, there are other paper sizes closer to the page size, yet for some reason the smallest size, #1 (40 × 40 mm), is selected. Incidentally, if you print from Adobe Acrobat with the custom forms in this state and the same settings, a predictable paper size like A3 (297 x 420 mm) is selected.Code: Select all

Final Note
- I am by no means claiming that it is a problem that the same paper size as Adobe Acrobat is not selected. It's only natural that different applications handle “Fit to Printer Margins" and "Select Paper Size by Document's Page Size” options differently, as they each have their own methods for adjusting page size to fit the paper size. However, as mentioned in the verification of the latter Case B, it feels odd that the smallest paper size of 40 x 40 mm is selected when the page size is 264 x 297 mm.
Thank you so much for your continued support.
Best regards,
