Document properties : pdf document size

Many pdf documents are generated using office tools like Word etc. as an alternative to printing a document. The size of the document will resemble the format of the page (A4, Letter etc.) e.g. 210 x 297 mm .

In a professional environment, e.g. newspaper industry, the document size of a pdf (e.g. advertisement, photo) is very important because it is an indication how the contents of the pdf will show up on a newspaper page. It is no problem if it’s too large, then you can shrink it. It may be a problem if it’s too small because you cannot blow it up without distorting the contents.

The Documents Properties shows the “file size” but in a graphical oriented environment we must know the “document size”.
Is it possible to show that value as part of Document Properties ?
