sizes made easier?

[CoreyD]

Wheres or what is a good tool.
With all the different brand sizes and rings etc. wheres a good place to find a measurement graph so when I look at a purchase or if i have a blind cigar in front of me to look up what it is or what to expect.
This would help in many ways for the answers for the not having to much time to smoke, to Am I really getting a deal going small size, to how big is this darn thing, to hmm wonder what this size is called.
