Picture Frame Rabbets: The Essential Guide to a Perfect Fit
The picture frame rabbet is the recessed channel or inner lip on the back inside edge of a frame's molding. It is perhaps the most critical structural element for ensuring a secure, stable, and professional fit for your artwork. The rabbet's dimensions—specifically its depth and width—determine how the "art package" (the artwork, glazing, and backing) sits inside the frame. Understanding the rabbet is essential for any artist or collector seeking a flawless presentation.
The Anatomy of a Frame: The Rabbet's Role
Think of the rabbet as the functional ledge that holds everything in place. In a traditional frame, this L-shaped recess is designed to house the complete art package. The "rabbet depth" (or height) must be deep enough to accommodate the thickness of all your components combined: the glazing (glass or acrylic), any matting or spacers, the artwork itself, and the backing board. The "rabbet width" refers to the width of the lip that will cover the front edges of your artwork.
Measuring for Success: Why Rabbet Depth is Crucial
To ensure a proper fit, the frame's rabbet depth must be slightly deeper than the combined thickness of your artwork package. If the rabbet is too shallow, the backing board will not sit flush with the back of the frame, making it impossible to secure properly. For example, if you are framing a 1/8" thick art panel with a 1/8" thick backing board, you will need a frame with a rabbet depth of at least 1/4". For stretched canvases, it's crucial to measure the exact thickness of your stretcher bars (e.g., 3/4", 1.5") to select a frame with a corresponding rabbet depth.
Rabbets in Different Frame Styles
The concept of the rabbet varies slightly between frame styles. In Traditional and Contemporary frames, it is the classic L-shaped channel. In Floater Frames, which are designed for canvases, there is no front-facing lip or rabbet width. Instead, the "rabbet" refers to the total interior depth of the frame itself. This depth must be sufficient to house the canvas, which is then secured from the back, creating the signature "floating" illusion.
Why Getting the Rabbet Right Matters
Selecting the correct rabbet dimensions is non-negotiable for a high-quality presentation. A proper fit ensures the artwork is held securely, preventing it from shifting or potentially being damaged. Aesthetically, it guarantees that all components sit flush within the frame, resulting in a clean, professional look from all angles.
