Picture Frame vs Shadow Box
One difference, and it is entirely practical: how much space there is between the backing board and the glazing.
By Janet H. · Published
If the thing you are framing has any depth to it — a medal, a jersey, a pressed flower, a set of keys — you need a shadow box. Everything flat goes in a picture frame.
A picture frame holds artwork against a backing board with a couple of millimeters of clearance. A shadow box has an inch or more, so an object can be mounted without being crushed against the glazing.

The difference, precisely
| Picture frame | Shadow box | |
|---|---|---|
| Internal depth | A few millimeters | Typically 1 to 2 in, sometimes more |
| Holds | Flat paper, photographs, prints | Objects with dimension |
| Mounting | Held flat by the backing board | Pinned, stitched or adhered to a fabric-covered board |
| Glazing distance | Touching or nearly touching the art | Well clear of the object |
| Weight | Light — mostly the glazing | Heavier — deeper molding plus the object itself |
| Hanging | Usually adhesive strips are fine | Often needs a hook; check the total weight |
| Cost | Low at standard sizes | Higher — more material, deeper molding |
What actually needs a shadow box
- Medals, coins, badges and pins. Anything that stands proud of a backing board.
- Jerseys and textiles. Folded fabric has real depth, and a jersey pressed flat against glass looks wrong and creases permanently.
- Pressed flowers and botanicals. These are borderline. Genuinely flat pressings work in a float frame; anything with remaining thickness needs the clearance. Floating frames covers the flat case.
- Keepsakes and collections. Ticket stubs plus a photograph plus a small object — the composition needs depth to sit at different levels.
Mounting inside a shadow box
This is the part people underestimate. The object has to be held against a vertical surface, permanently, without damaging it.
- Pins into a fabric-covered board — the conservation standard. Reversible and holds nothing with adhesive.
- Stitching — for textiles. Thread through the backing board, invisible from the front, and entirely reversible.
- Archival adhesive — for lightweight paper items only. Never ordinary tape or a glue stick; both yellow and both stain.
Whatever the method, keep the object clear of the glazing. Anything touching the glass will eventually stick to it in a humid room, which is the same failure a mat prevents in an ordinary frame.
Hanging a shadow box
A shadow box is heavier than a picture frame of the same face size — more molding, plus the object. Weigh it rather than assuming, then match it to a method rated above that figure.
Depth also changes the mechanics: a deep box sits further off the wall, so it pivots more easily on a single fixing. Use two fixings spaced across the width, always, regardless of what the weight rating alone would allow. The weight ladder and no-drill kits.
The picks in full
Each entry states what it is for, the specification that decides it, and who should skip it.
1. Best for near-flat keepsakes
Americanflat Floating Frame
Americanflat
A double-glazed float frame handles pressed flowers, tickets and thin textiles without the cost or bulk of a shadow box.
- Construction
- Print sits between two glazing panes — edges stay visible
- Sizes
- Standard sizes from small formats up
- Best for
- Deckle-edge prints, pressed botanicals, odd-size art
- Orientation
- Wall or tabletop
The spec that decides it: Two glazing panes with the item floated between them.
Skip it if: The object has real depth. Two panes of glazing will crush it.
2. Best deep-profile frames
Craig Frames Picture Frame
Craig Frames
The widest choice of deep moldings here, including profiles with enough rebate to approach shadow-box territory.
- Sizes
- Very wide size range, including oversize and non-standard
- Glazing
- Lightweight shatter-resistant acrylic front
- Profiles
- Contemporary through ornate; wide molding choice
- Origin
- Made in the USA
The spec that decides it: Deep molding profiles available across a very wide size range.
Skip it if: You need a full inch or more of internal depth — buy a purpose-built shadow box.
3. Best for flat memorabilia
Golden State Art Matted Picture Frame
Golden State Art
Acid-free matting in standard step-downs, which is the right treatment for a certificate, a program or a photograph with no depth to it.
- Common openings
- 11x14 frame matted to 8x10; 16x20 matted to 11x14
- Mat
- Acid-free on the archival lines
- Glazing
- Glass or acrylic by line
- Packs
- Often sold in multi-packs
The spec that decides it: Acid-free matting with standard step-down openings.
Skip it if: The item is three-dimensional. A mat holds it off the glazing but does not give it room.
4. Best fixing for a deep box
OOK Monkey Hook Drywall Picture Hanger
OOK
A shadow box is heavier and pivots more easily than a flat frame. Two of these, spaced across the width, hold it flat and level.
- Rated weight
- 35 lb on 1/2 in residential drywall; 50 lb on 5/8 in commercial drywall
- Wall types
- Hollow drywall only — not studs, not plaster over lath, not masonry
- Tools
- None — push and twist by hand
- Wall damage
- One pin-sized hole
The spec that decides it: 35 lb each on 1/2 in drywall — use two, spaced, and stay well under the combined rating.
Skip it if: The box is light and flat-backed — adhesive strips would leave no mark at all.
Common questions
What is the difference between a picture frame and a shadow box?
Depth. A picture frame holds flat artwork against a backing board with a couple of millimeters of clearance. A shadow box has an inch or more of internal depth, so a three-dimensional object can be mounted without being crushed against the glazing.
Do I need a shadow box for a pressed flower?
Usually not. A genuinely flat pressing works in a double-glazed float frame, which is cheaper and less bulky. If the pressing still has visible thickness, or you want it to cast a shadow, use a shadow box.
How do you mount something in a shadow box?
Pins into a fabric-covered backing board for most objects, stitching for textiles, and archival adhesive for lightweight paper only. Never ordinary tape or a glue stick — both yellow and both stain. Keep the object clear of the glazing so it cannot stick to it.
Are shadow boxes heavier than picture frames?
Yes — more molding material plus the object inside. They also sit further off the wall, which makes them pivot more easily on a single fixing. Weigh yours and use two fixings spaced across the width, regardless of what the rating alone allows.
Can you use a shadow box for a flat print?
You can, and the deep recess creates a dramatic shadow around the artwork. It costs more and adds weight for a purely aesthetic effect, so it is a style choice rather than a requirement — a deep-profile picture frame gets you most of the way for less.
