Whilst I can't give you the numbers you want, I hope the following is useful: I'm 188 cm tall and can lie comfortably in the centre section 4 seats of a 747. I can't do that in the 3 side seats of the 747 or the centre 3 of a 767 (feet or head hang into the aisle which isn't a good thing!). Oh the days when that WAS possible (ie <50% load factors).
