How to Make a 10×10 Frame | Square Build Secrets

Building your own 10×10 frame is a straightforward weekend project that lets you skip retail markups and custom-size the molding to your exact taste. The entire process boils down to cutting four 45-degree miters, creating a groove to hold the artwork, and joining the corners with glue and mechanical fasteners.

Whether you need to frame a square art print or a photo, the same core woodworking sequence applies. You can tackle this with a miter saw, a router, and a few clamps—no elaborate workshop required.

What Exactly Is A 10×10 Frame?

A 10×10 frame means the inside opening—the visible window where the picture sits—measures exactly 10 inches by 10 inches. The exterior dimensions will always be larger, because the molding’s width adds to the overall footprint. A frame built for a bare 10 x 10 print may not fit if you plan to add a mat, glass, or thick backing, since those layers consume depth inside the rabbet (the recessed groove holding everything).

Decide upfront what the frame must hold. This choice determines your molding width and the rabbet depth required.

How To Cut And Join The Frame Pieces

The quality of a square frame lives or dies in the corner joints. Start by cutting all four pieces to length with 45-degree miters at each end, so the corners meet at perfect right angles. Kreg’s frame guide confirms the 45-degree cut is standard.

Before any glue touches wood, dry-fit the four pieces and check every corner with a carpenter square. Home Depot’s DIY frame guide emphasizes this step: clamp the frame, confirm it’s square, then fasten. Misaligned corners only compound once glue sets.

• Cut all four miters at 45 degrees.
• Dry-fit and clamp with a carpenter square to verify right angles.
• Apply wood glue to each mitered face.
• Join with 1 1/4-inch pocket-hole screws (Kreg’s recommended method) or finishing nails from Home Depot’s approach.

Rabbet, Backing, And Assembly

The depth matters: it must accommodate the combined thickness of your mounting board, the print, any mat board, and the glass. If the rabbet is too shallow, the frame won’t close flush, and the glass can bow or crack.

Once the frame is assembled and the glue dries, insert the artwork stack from the back. Home Depot’s method uses layered hardboard pieces to create an offset so the glass, picture, and backing sit flush with the frame’s rear edge—a simple shim system that prevents rattling and keeps everything compressed. Secure the backing with brads or glazier points to hold tension on the stack.

Finishing And Hanging Hardware

Fill any visible gaps or screw holes with wood filler, let it dry completely, then sand the entire frame smooth. Start with 120-grit and move to 220-grit for a polished surface before applying stain or paint.

For wall display, Kreg’s guide suggests routing a keyhole groove on the back of the frame after assembly—a clean, low-profile hanging method that keeps the hardware invisible from the front. Place it slightly above center so the frame’s weight hangs naturally. If you’d rather buy a ready-made option that’s already finished and sized, see our tested choices for the full breakdown.
