List of average page number per journal
There is no certain rule of thumb for determining the number of pages in a journal article. If you are asking for a sheet with all the information about it, then I think nobody here is going to be able to help you out. If you need information on a specific journal, however, then you may look into the journal's "Author Information/Instruction" page or "Paper Submission Page".

However, you should also note that there are often three different types of paper welcomed by many journals:


Short paper (least number of pages) E.g. 8 pages for IEEE
Regular paper (more pages) e.g. typically 12 double column pages
Review papers (most pages). e.g. I don't know.


However, everything depends again on publishers, including whether it is a double column or a single column format. Typically single column formats have higher page numbers than the examples given above.
