Trim and molding are the frames that define room edges — the transitions between surfaces that either make a room feel finished or show where the work stopped short.
Crown Molding
Crown molding adds visual height to a room and frames the ceiling line. Standard crown sizes range from 3 to 6 inches.
Baseboard
Taller baseboards — 4 to 6 inches — make rooms feel more substantial. The profile should be proportional to room size.
