Crown Molding Anatomy

Attached is a picture of the basic frame work for crown molding including meaning and placement of the following :

Note : Measurements will always reflect an installed piece of crown. ( i.e. How it sits ).

Height : Measurement from the ceiling to the bottom of the crown end.

Projection : Measurement from the wall to the edge of the crown end.

Face : Measurement of the crown molding from top to bottom  (Note : do not confuse with how the crown molding will sit as that would be the Height and Projection. ).

Length : Measurement of the entire crown molding stick.
