Given the size of the shelf itself, are there ratios that are used
to come up with the size of the back piece that extends below
the shelf? I'm thinking about two thirds the depth of the shelf.

I picked two thirds because it seems to be a ratio that is used
alot - at least in the stuff that I have read.

Were it that simple ... good design has few rules, most of which are broken
constantly and to good effect.

IOW, please your own eye ... in this case there is no structural reason for
the ratio you've picked.
