Selecting the Right Rabbet for Your DIY Frames

Every frame has a rabbet, also known in our system as the R measurement, which is also the inside depth of the frame. This is where your materials go. When choosing DIY frames , color and style are important, but the rabbet is equally as important. This is because the rabbet needs to be deep enough to hold all the materials being framed. For wood mouldings, the rabbet is the area from under the lip of the frame to the bottom of the frame.

The rabbet for metal frames is slightly different from that of the wood frames. See illustration below:

To show you how to use the select the proper sized wood frame rabbet, see the following example:

If we choose frame 227516, Basics- Cherry, the R measurement is 15/16.”

Example of where to find the R measurement in our catalogue (paper or online).

For the frame to conceal your materials properly, the thickness measurements of acrylic, mat, artwork, and mounting board must add up to less than 15/16.” Here are the thicknesses for the following common materials:

Standard acrylic = 3/32” (0.09375)

Standard mounting board = 1/8” (0.125)

4-ply mat = 1/16” (0.0625)

This “sandwich” adds up to a total thickness of: 9/32” (0.28125)

Now add the thickness of your art. If the total of all items in the “stack” adds up to less than the frames R depth, you are good to go!

Remember: if you are going to double or triple mat your artwork, you must add the thickness of every mat to the “stack.” If you happen to choose a different ply of mat (6ply, 8 ply), or different type of acrylic or mounting board for your DIY frames, the thickness may not be the same as the above example, so be sure to take note of that.

We provide the rabbet depth (seen like this R: 9/16”) for each frame profile on our website or in our paper catalogue to help you make the correct selection for your project.
