How the Custom Frame Builder Works
1. Choose your moulding
Browse thousands of profiles across wood, metal, and ValuCore. Every profile in our catalog can be built to any size — nothing is limited to stock dimensions.
2. Enter your exact size
Type your artwork’s width and height in 1/16" increments. If you’re framing to a mat, enter the outside dimensions of the mat board instead.
3. Add mats, backing, and glazing
Layer up to three custom-cut mats, choose a backing board, and add plexiglass or acrylic glazing. Each is cut to match the frame you’ve specified.
4. Order and assemble
Your frame arrives cut to size with all assembly hardware included. Corners join squarely in a few minutes — no tools, no trimming, no trip to the frame shop.
What You Can Customize
Size — any dimension in 1/16" increments, with no size premiums or stock-size rounding.
Matting — one, two, or three layers, in your choice of colors and reveal widths, cut to your opening.
Multi-opening mats — display several photos in a single frame with a custom collage mat. Design your own opening layout, sizes, and spacing in our multi-opening mat designer, then order it with a matching frame.
Glazing — plexiglass or acrylic, cut to size, with the option to skip glazing entirely for canvas or floater builds.
Backing — foam board or acid-free backing sized to your frame.
Prints — upload an image and we’ll print it to your specified size, then frame it in the same order. See Print & Frame.

Custom Frame Builder FAQs
What sizes can I build a custom picture frame in?
Any size, in 1/16" increments. There are no stock sizes and no upcharge for unusual dimensions — the moulding is cut to whatever you enter.
How do I measure for a custom picture frame?
Measuring your art correctly ensures a perfect fit every time. We build our frames based on the inside dimensions of the frame’s lip, which is called the rabbet. Do not measure the outside edges of the frame.
Framing without a mat: Simply measure the exact width and height of your artwork. Your art size matches your frame size.
Framing with a mat: Your frame size will match the outside dimensions (OD) of your mat board. The inside window opening of the mat will be cut to the exact size you enter. Whether you measure to the edge of the paper or the edge of the image, we highly recommend adding a 1/8-inch overlap. This overlap is very important because it holds your paper securely in place and keeps it from falling through the window opening of the bottom mat. It also ensures your image looks perfectly even all around. If you add a second or third mat layer, their openings will automatically be calculated based on the size of this first mat’s opening.
Always double-check your numbers to the nearest 1/16-inch before placing your custom picture frame order!
Does the frame arrive assembled?
Frames ship disassembled with all hardware included, which protects the corners in transit and keeps shipping costs down. Assembly takes a few minutes with no special tools.
Can I order just the frame without mats or glazing?
Yes. Every component is optional. Build a bare frame, or add only the pieces you need.
What’s the largest frame I can order?
Maximum size varies by moulding profile, since wider mouldings support longer spans. The builder will flag it if your dimensions exceed what a given profile can support.
