When ordering a custom acrylic display case, one of the most common questions is how much extra room to leave around the item. The case should fit cleanly, but it should not be so tight that the collectible scrapes the sides or becomes difficult to place inside.
A little clearance can make the difference between a display case that feels easy to use and one that feels frustrating.
What Does Clearance Mean?
Clearance is the extra space between your collectible and the inside walls of the acrylic display case.
For example, if your collectible measures 7 inches wide and you order a case with an inside width slightly larger than 7 inches, that extra space is the clearance.
Clearance helps make sure the item can sit inside the case without being forced into place.

Why Clearance Matters
Collectibles are not always perfectly square. Boxes can have shrink wrap, folded edges, slight bulges, corner wear, or uneven packaging. Even a small difference can affect how the item fits inside a case.
If the case is too tight, you may have to push the item in, which is not ideal for sealed packaging or display pieces. A little extra room helps protect the edges and makes the case easier to use.
How Much Extra Room Should You Add?
For most boxed collectibles, adding a small amount of extra room is usually a good idea.
A simple starting point is to add a little clearance to each measurement:
- Height: add a small amount above the tallest point
- Width: add a small amount beyond the widest point
- Depth: add a small amount beyond the deepest point
The exact amount depends on the item. A smooth, square box may only need a small amount of clearance. An item with loose wrap, uneven packaging, or delicate corners may need more room.
When You May Want More Clearance
You may want to add more clearance if your collectible has:
- Loose or raised shrink wrap
- Rounded or uneven edges
- A box that is not perfectly square
- Corners you do not want touching the acrylic
- Packaging that has slight bulging
- Extra pieces that stick out from the main shape
If you are unsure, it is usually better to leave a little more room than to make the case too tight. For sealed trading card products, you can also browse our Pokémon acrylic display cases to compare standard case options.
Do Not Measure Too Tight
A custom acrylic display case should not fit like a sleeve. The goal is display and protection, not pressure.
If your measurements are exactly the same as the item, the fit may be too close. This can make the item harder to place inside and may cause contact with the acrylic walls.
For collector items, especially sealed boxes, a slightly easier fit is usually better than a tight fit.
Double-Check Height, Width, and Depth
Before entering your custom case dimensions, check each number again:
- Height is bottom to top
- Width is left to right across the front
- Depth is front to back
Depth is the one people often mix up with width, so take a second look before ordering.
Use Clearance to Make the Case Easier to Display
Good clearance is not just about fit. It also helps the item look better on a shelf.
When the collectible has a little breathing room, it can sit cleanly inside the case without looking jammed in. That makes the overall display feel more intentional and polished.
FAQ
Should an acrylic display case fit tightly?
Usually, no. A display case should have enough room for the collectible to fit comfortably without needing to force it inside.
Should I add clearance to every measurement?
In most cases, yes. Height, width, and depth can all benefit from a small amount of extra space.
What if my collectible has shrink wrap?
Measure the item with the shrink wrap included. If the wrap is loose, raised, or uneven, consider adding extra clearance so the case is not too tight.
