Definition: The moulding profile is the two-dimensional shape of a picture frame moulding as viewed from the end of the moulding stick. It determines the contour, depth, and visual character of the frame, influencing both the aesthetic appeal and the structural fit for artwork, glazing, mats, and backing.

Overview

The profile of a moulding is a critical consideration in picture framing. It affects how the artwork is seated, the shadow lines created, and the overall visual impact. Profiles can be simple and flat or highly decorative with carved, rounded, or beveled features.

Components and Features

Rabbet: The recessed area where artwork, matting, and glazing sit. Its depth and width are integral to the moulding profile.
Lip: The inner flange that supports and secures artwork within the rabbet.
Decorative Contours: Includes grooves, bevels, fillets, and other surface features that add aesthetic detail.
Structural Considerations: The profile contributes to the frame's ability to hold heavy or layered materials securely.

Materials

Moulding profiles can be created in a variety of materials:

Wood (hardwoods like oak, cherry, mahogany)
Metal (aluminum, brass, or other alloys)
Composite or synthetic mouldings (MDF, polyurethane)

Function in Framing

Defines the visual style and character of the frame.
Determines how artwork, mats, and glazing sit within the frame.
Contributes to the overall structural stability of the frame.
