Example of a Bloch and Capezio sizing equivalency? - capezio size chart

Who knows of any size equivalence between these two brands? I Bloch Serenade 6, signed Bloch 6.5 and wondered what would be the size of Capezio. Size charts give me another number! I'm looking for experience and knowledge, thank you!
