For those of you familiar with hall and parlour style of TF homes are there guidelines for the various proportions?

4 bent, 3 bay, 2 story and maybe a 3rd floor loft with a 12:12 roof.

Would the middle bay be 10 - 12 ' wide? depth? two outer bays?

I realize this depends alot on the size of the house, but am curious from some historic examples some of you may have seen.
