Michael,
The 60th Ala.'s 2nd National was 47" x 72-5/8" (Chicago Historical Museum data sheet obtained through Gregg Biggs), The 44th Ga.'s was 40" x 50-1/2", the 60th Ga.'s was 48" x 69-1/4" (both of these came from "Confederate Flags in the Georgia State Capitol Collection," Paul Ellingson, ed., 1994) and the 12th Ala.'s was 27" x 45" (from "Civil War Flags of Alabama", Glen Dedmondt, 2001)
Hope this was what you were looking for.
Charles
P.S. I have digital photos of the 60th Alabama's 2nd National if you're interested.
