The default size of Links that includes the .cgi scripts, lib files, and templates is 500K. In terms of the pages that are built...that varies depending on the following factors:
1) # of categories
2) # of modifications you add
3) # of links
I think that I have seen ranges between 20 MGs and 60 MGs.
My directory is 20 MGs with the following elements:
1) 2,409 Links
2) 396 Categories
3) 40 Mods installed
