Beyond the scope of a discussion IMO.

I have some PDFs in my personal laptop. I can find it for you when I am home. In general you can find some very good information in the PDF here.

Fantastic details on many types of fits.
Check this link too. The fits are thought out for 3D Printing but you can learn quite a lot from here too.
