How to Measure for a Custom Acrylic Display Case

Separate inside fit, outside limits and access

Write down these three checks separately. A case can have enough room around an object once closed while its doorway is too small to get that object inside.

Usable inside dimensions

The clear width, depth and height available to the contents in the assembled case. Identify the supporting surface from which height is measured, and any inward-projecting lip, divider or hardware.

Maximum outside dimensions

The space the finished case may occupy at your location, including its base and projecting fittings. Mark the shelf edge, nearby wall and any overhead limit. This is a constraint from your site.

Clear opening and operating space

The narrowest unobstructed opening on the insertion route, plus space outside the closed case for the door, removable cover and your hands during handling.

Use one labelled viewing direction: W is left to right across the chosen front, D runs front to back, and H runs upward from the stated support surface. Put the units beside every set of measurements and mark the front on a sketch.

Measure the complete contents in display position

Record the largest occupied width, depth and height with every component that will stay inside the case. Measure the assembled arrangement, including an object's own stand, mounting board or insert.

A model may extend beyond its wheels at the mirrors or antenna. A pair of shoes occupies a different envelope when angled on a stand. For several items, arrange the full group and measure its outermost points. Photograph the arrangement from the front, side and above, with the measurement points marked.

Distinguish the object's stand from a base supplied as part of the case. State whether an insert sits on top of that case base or within a recess. Ask the supplier to show the resulting support surface and usable height on the assembly drawing.

Keep measured contents and requested inside space in different fields. Agree room for appearance, projections and handling for the actual design; there is no single clearance to add to every acrylic display case.

Once the dimensions are recorded, compare the hinged, lift-off and open-face access options. If gifts sit in fitted pockets, add the gift set and insert layout to the same drawing review.

Check the measurement points for your reference format

A removable cover, hinged case and open box need different access checks. Use the catalog references below to explain the intended format, then confirm the proposed construction on a drawing.

These are appearance and format references. Their photographs do not establish dimensions, base materials, load capacity or a standard allowance. An open box used upside down as a support needs a separate load and stability review.

A filled record can show what still needs confirmation

This fictional example records an object and a location constraint without guessing the case size. It is a worksheet demonstration, with no connection to a customer order or catalog specification.

The difference between these two measured envelopes is not an approved wall thickness or clearance. The base, joints, hardware and access path still need space. If the contents and location cannot accommodate the proposed construction, revise the layout or format before approval.

Copy this dimension brief for your supplier

Fill in what you have measured and mark uncertain entries To confirm. Keep photographs and sketches under the same revision so the supplier can distinguish facts from requests.

Confirm the assembly drawing, then trial-fit the sample

Approve a drawing that labels usable inside dimensions, complete outside dimensions and the clear opening. Agree the tolerances and how each dimension will be checked before production.

1. Check the front, units, revision and height datum against your measurement record. Identify the base, inward projections and opening direction.
2. Have the supplier show the proposed opening movement and removal route. Check those against the shelf, wall and overhead space at the location.
3. Fit the actual contents and inserts in a representative assembled sample. Open, close, insert and remove them in the intended sequence; record the result and any revisions.

Dimensions are one input to thickness and support selection. Review box seams and fit separately, then record the agreed checks in your sample approval.
