Just trying to find out if anyone has knowledge of why this Page size discrepency is so.
In the first image, the Page Size shows 300 odd pixel width, yet, in Document Settings it shows 12,000 px width.Thankyou for all replies.
That's because you're working on pixels. If you start a new document, at 300 dpi and choose 3840x2160 pixels, the file informations and the document properties will match. but is you change the resolution of the document to 96 dpi, the document size will change. If you input again 3840x2160 pixels at 96 dpi, the document properties will show 12000 pixels. It's justa mathematical issue:
300/96= 3,125,
12000/3840=3,125,
6750/2160=3,125
