Having a Brain Fart on Snap on Combs.

I totally know this but my mind has left me. What are the common lengths of snap on comb? I know there is a 1, 1.5, and 2 (lots more but I am talking Teddy Bear lengths) and what is the exact length they leave the hair. Is a 1 blade a 1 inch blade or what. Man my brain is stupid right now. Thanks guys.

1 comb leaves about 3/4 inch. #1.5 leaves about 5/8 of an inch, and a #2 leaves about 3/8 of an inch. the longer comb sets are more varied by who makes them. for example, a Romani C comb leaves about 13/16 of an inch, while a Laube C comb leaves 1 1/2 inches. but the 1, 1.5, and 2 combs are all about the same for all companies
