Defining look-book format

Re-visiting the format I came across a problem with my idea in that the descriptions I originally want to implement will impede on the space for the images in the look book. Another problem with the format is that the pages are harder to bind and I would have to come up with a way of efficiently binding it together but don't have enough time to do this as time is running out.

I have had a couple of ideas for the format and sizing of the look book. I want to keep it small but at the same time maximise the space in the double page spreads to showcase the typeface.

 C5 (229mm x 162) with a double page spread size of 324mm x 229mm.

 I want to either have the look book wrapped in a belly band or have a sleeve wrap on it.

 B6

C6

I think that the formats B6 and C6 are to small for what I want to produce and will be going for the C5 format.
