How to Choose the Right Shadow Box Depth | SBF

Choosing the right depth for your shadow box is one of the most important decisions you will make, and it is often the one people overlook. Too shallow and your items press against the glass. Too deep and everything looks lost inside the frame. This guide walks you through each depth option with real measurements so you can pick the one that fits your keepsake naturally.

Standard Depth: 0.75 Inches

Standard depth shadow boxes accommodate flat or nearly flat items. Think pressed flowers, photographs, postcards, patches, lapel pins, and paper memorabilia like concert tickets or wedding invitations. At three-quarters of an inch, you have enough room for items that sit close to the backing without touching the glazing. This depth works beautifully when you want a sleek, low-profile look on the wall. It is also the lightest option, which makes hanging simple. If your keepsake lies flat and does not have any real thickness to it, standard depth is all you need.

Medium Depth: 1 Inch

One inch of depth opens the door to slightly bulkier items. Military medals with ribbon bars, stacked coins, small seashells, dried flower bouquets that have a little volume, and thin fabric items like baby booties or a christening bonnet all fit comfortably here. The extra quarter inch might not sound like much, but it gives your items breathing room and creates a subtle sense of dimension when light catches them from the side. Medium depth is our most popular option because it handles the widest range of keepsakes without adding unnecessary bulk to the frame.

Deep: 1.25 Inches

When your items start to have real dimension, deep shadow boxes step in. This depth works well for thicker medal sets, small figurines, pocket watches, dog tags on chains, and items like a folded handkerchief or a small piece of jewelry in its box. At one and a quarter inches, you get enough clearance that nothing feels cramped, and you can start layering items at slightly different depths for a more dynamic look. If you are unsure whether medium or deep is right, deep is usually the safer choice because the extra space is always welcome.

Extra Deep: 1.75 to 2 Inches

Extra deep shadow boxes are built for items with genuine heft. Folded flags, baby shoes, small sports equipment like a baseball or hockey puck, thick medals, and chunky keepsakes all need this kind of room. At nearly two inches of depth, you can also arrange items on small risers or platforms inside the box to create visual layers. This is the depth we recommend most often for military retirement shadow boxes, where you might combine medals, rank insignia, patches, and challenge coins in a single display that tells the story of an entire career.

Ultra Deep: 2.5 Inches and Beyond

Some keepsakes simply need more space. A folded jersey, a pair of ballet slippers, a large seashell, a football, or a thick sculpture all call for ultra deep shadow boxes at two and a half inches or more. At this depth, the shadow box becomes almost like a display case, and the visual effect is dramatic. Items appear to float inside the frame, surrounded by space that draws the eye inward. We handcraft ultra deep frames with reinforced construction to handle the extra weight, so the finished piece hangs securely and looks stunning on the wall.

How to Measure Your Items

The simplest way to choose your depth is to measure the thickest item you plan to display. Lay it on a flat surface and measure from the base to the highest point. Then add at least a quarter inch of clearance so nothing presses against the glass. If you are combining multiple items at different thicknesses, measure the bulkiest one and use that as your guide. And if you are still not sure, our team is always happy to help. Send us a photo of your keepsake and we will recommend the right depth for your project.

Frequently Asked Questions

What happens if my shadow box is too shallow for my items?

If the depth is too shallow, your items may press against the glazing, which can cause damage over time and looks cramped. It also creates pressure on the glass or acrylic, which is not ideal for long-term display. We always recommend at least a quarter inch of clearance between your tallest item and the glazing.

Can I mix items of different thicknesses in one shadow box?

Absolutely. Choose your depth based on the thickest item, and the thinner pieces will sit naturally against the backing. You can also use small risers or mounting techniques to bring thinner items forward and create a layered, dimensional look.

Do deeper shadow boxes weigh significantly more?

Deeper frames do add some weight because of the additional moulding material, but the difference is modest. A standard depth shadow box and an extra deep one in the same outer dimensions typically differ by less than a pound. We include sturdy hanging hardware with every frame to ensure secure mounting regardless of depth.
