Traditional overlay's smaller doors overlay the cabinet frame 1/2" on each side, leaving a 1" reveal at the top, bottom and sides of the face frame.
Modified doors and drawer fronts overlay the face frame 1/2" on the top and bottom and 1-1/4" on each side, leaving a 1" reveal at the top and bottom and a 1/4" reveal on each side.
Inset doors and drawer fronts fit between the stiles and rails of the face frame, with a 3/32" gap between doors or fronts and the face frame.
The Beaded Inset option includes a narrow groove routed into the face frame that outlines door and drawer front openings.
