Princeton mouldings are given more profiling or curves than the ranch styles. They often incorporate an "ogee" shape on the nosing or edge of the pattern. The shape defines a "colonial" look and feel. Keep in mind, when selecting your mouldings, that larger homes should use larger mouldings to maintain their proportion.
