Book Shape and size

After a lot of thought as to what shape and size I should make my book, I looked at a lot of ideas such as shapes of Family Albums or Wedding Albums.
Jake’s nan often refers to herself as a hopeless romantic, and she has been engaged twice as well as being married to her ex-husband whom she still has very strong feelings for, I felt it could be interested to have the book in a similar format to a wedding album, which in my experience, they have almost always been square so I will be making my book in this format, I decided to go with a simple 16x16 cm sizing as I feel this is a good size to be able to enjoy the visuals and details in the imagery.

I am slightly concerned about the length of the book as I feel it may be too long and drag on a little bit, but the reason I wanted it to belong is that Jake’s nan has had a long and very interesting life and so I feel the book should reflect on this and should most of the important parts, which there are many.
