Parametric Picture Frame Generator

Parametric Picture Frame Generator

Make a picture frame that actually fits the picture you have — wild concept, I know.

This generator lets you create a clean two-piece picture frame with adjustable sizing, multiple frame profiles, a matching back plate, alignment pegs, and a hidden rear keyhole mount. Choose a standard photo size or enter your own custom dimensions, tune the frame style, and generate a printable frame without starting from scratch every time.

Perfect for family photos, pet pictures, artwork, memorial frames, holiday gifts, desk decor, wall displays, and custom home decor projects.

Key Features

Standard or Custom Picture Sizes

Choose from common US photo sizes or enter your own custom width and height.

Built-in standard sizes include:

• Wallet 2×3
• 3.5×5
• 4×4
• 4×6
• 5×5
• 5×7
• 6×8
• 8×8
• 8×10
• 8.5×11 Letter
• 11×14
• 12×12
• 12×18
• 16×20
• 18×24
• 20×30

Portrait and landscape modes are included, so you do not need separate files for each orientation.

Real Front Overlap

The frame opening is smaller than the picture size, so the front frame overlaps the picture edge and holds it against the back plate.

This is controlled by the picture overlap setting.

Smaller overlap shows more of the picture. Larger overlap gives a stronger hold.

Matching Back Plate

The back plate matches the outside shape of the frame and holds the picture from behind.

It also has a shallow picture recess so the photo or artwork sits centered instead of sliding around like it has somewhere better to be.

Alignment Pegs

The back plate has four corner pegs that line up with matching holes in the frame.

The sockets include adjustable tolerance, with 0.2 mm as the default starting point.

This helps the frame and back plate line up cleanly during assembly.

Hidden Rear Keyhole

The keyhole mount is built into the back plate and cut from the rear only.

That means it does not show through the front of the frame.

You can turn the keyhole on or off and choose the mount side.

Frame Profile Styles

Choose between several frame looks:

• Modern Flat
• Soft Bevel
• Stepped Gallery
• Deep Shadow Box
• Rounded Chunky

Each profile changes the style without needing a separate model file.

Adjustable Frame Controls

Tune the frame to match your print, photo, or display style:

• Frame width
• Frame depth
• Front lip height
• Corner radius
• Opening corner radius
• Picture overlap
• Picture clearance
• Back plate thickness
• Peg diameter
• Peg tolerance
• Keyhole size and placement

Built-In View Modes

Use different views for previewing and exporting:

• Assembled
• Frame Only
• Back Plate Only
• Exploded View

This makes it easier to check the fit, inspect the parts, and export only what you need.

Why I Made This

A frame should not need to be remodeled every time the picture size changes.

This generator gives you a reusable frame tool for photos, prints, artwork, gifts, and home decor. Pick the size, choose the style, adjust the fit, and print the frame you actually need.

Simple. Useful. Customizable.

Exactly how parametric tools should be.

Assembly Notes

Place the picture into the back plate recess, then press the frame and back plate together using the four alignment pegs.

Printer tolerances vary, so adjust peg tolerance or back plate clearance if your fit is too tight or too loose.

The default 0.2 mm peg tolerance is a good starting point for most tuned printers.
