PDFs: How big is too big?

[Jon Harvey]

Hi all,



We would like to place some of our larger manuals online for download
but don't know whether the PDFs will be too big. Is there a general
guideline limit (1MB, 10MB, 25MB?) for the size of a PDF for download?
Most of  our users are corporate, so we anticipate each will have a
high-speed connection. However, we certainly can't guarantee all of them
will be. 



Any thoughts?...............Jon
