Shadow Box Frames: What They Are and How to Choose the Right One

Updated

A shadow box frame is a picture frame with extra depth, so it can hold three-dimensional objects instead of just a flat print. Choose one when you want to display items like medals, ticket stubs, small collectibles, or clothing that a standard frame can't contain. The key decisions are interior depth, outer size, backing and mounting method, and how the frame will hang.

How a shadow box differs from a regular frame

A standard picture frame holds a flat print against glass or acrylic. A shadow box adds space between the glazing and the backing, creating a cavity where objects sit. That depth is what lets you display a medal on a ribbon, a folded shirt, or a group of small souvenirs without crushing them.

On ArtToFrame, Shadow Box Frames appear as a distinct product category alongside Picture Frames, Matted Frames, Collage Frames, and Acrylic Floating Frames. The site also lists related display options such as Diploma Frames, Gallery Walls, and Custom Cut Mats, which can be combined with a shadow box layout.

What you can display

Shadow boxes suit items that have some thickness or that you want to present as a small scene. Common uses include:

  • Medals, pins, and ribbons
  • Ticket stubs, programs, and maps
  • Small 3D objects such as shells, keys, or figurines
  • Clothing or fabric, like a baby onesie or a jersey section
  • Grouped photos and keepsakes arranged together

If your item is completely flat, a standard or matted frame is usually simpler and less expensive. A shadow box earns its cost when the object needs room to sit forward of the backing.

Choosing the right size and depth

Measure the object first, then add margin. You need two numbers: the interior depth (how far the object projects from the backing) and the outer frame size.

Decision What to check
Interior depth Must exceed the object's thickest point, with a little clearance so it doesn't touch the glazing
Outer size Large enough to leave visual breathing room around the object
Orientation Portrait or landscape, based on how the object reads best
Glazing Glass or acrylic; acrylic is lighter and safer for large or wall-mounted pieces

ArtToFrame's upload tool notes a minimum selectable area of 4" x 6" and a maximum of 56" x 56", which gives a sense of the size range the platform works with. For a shadow box, confirm the depth separately, since overall size alone doesn't tell you how much room is inside.

Planning the interior layout

A shadow box is a small composition, so decide placement before you mount anything.

  1. Lay the object and any accompanying items on the backing and move them around until the arrangement looks balanced.
  2. Mark where each piece will sit, leaving even margins.
  3. Choose a mounting method that won't damage the item: pins, adhesive dots, or a fitted mat with a cut opening.
  4. For fabric or clothing, consider a backing board that supports the shape rather than stretching it.
  5. Check that nothing touches the glazing once the frame is closed.

A Custom Cut Mat can create a window that holds a flat photo while leaving a deeper area for a 3D object, combining two display styles in one frame.

What to confirm when ordering a custom shadow box

Because shadow boxes are often custom, ask the seller about these points before you buy:

  • Frame color and material
  • Available interior depths
  • Backing type and whether it accepts pins or adhesive
  • Glazing material (glass vs. acrylic)
  • Hanging hardware and weight limits
  • Production and delivery time

ArtToFrame's site shows a photo upload flow that accepts JPG and JPEG files up to 150MB, with RGB recommended for accurate color, and notes that larger files can be sent via WeTransfer or Dropbox. If your shadow box includes a printed background or photo, that upload process is where you'd supply it. The site also states that you must own or have permission to print any image you upload.

A quick decision guide

Choose a shadow box if your item has depth or you want a layered, dimensional display. Choose a standard or matted frame if everything is flat and you want a simpler, lower-cost option. For mixed displays, a shadow box with a custom-cut mat lets you combine a flat photo and a 3D keepsake in one piece.

Before ordering, measure your object's thickness, pick a frame size with margin to spare, plan the layout, and confirm depth, backing, glazing, and hanging method with the seller.
