I have 10' ceilings and took the hood all the way to the ceiling. I have 1' crown moulding, so tiled all the way up to crown (if we hadn't done the crown moulding, I would have taken the tile all the way up to the celing as well because my range wall was always intended to be the "feature" wall).
Sorry for posting the same, old tired picture of my kitchen!
