Because it was asked - let me answer :)
Tagger sized papers are generally 600x600 (sometimes a little bigger), and 72 dpi. They are used by those of us who make signature tags, and are not suitable for printing out and scrapbooking with. I think they could be used for smaller scale digital scrapbooking, but since I don't digi-scrap, I can't stay for sure.
I tried making the larger papers, but it makes my program run sooooooooooo slowly, I just gave up. :(
Hope that helps!
