I think 200 bytes is a reasonable lower limit. Under 200 bytes gets you a message about needing more substance (or some more tactful word) before an article can be created, along with a link to the sandbox for those who want to practice editing.
Why not have the software add {{autostub}} or [[Category:Wikipedia:Automatic stub]] to every new article below, say, 500 bytes? That would keep track of those and give stubhunters a list of what to look at. If it is a "legimate stub", replace the automated message with {{stub}}.
