How to Measure a Finished Picture Frame for Shipping
The print size on a frame label is not enough to choose its shipping box. Measure the finished frame, then measure the complete protective assembly. Those two records let you distinguish the object you are shipping from the space its packaging needs.
Use this worksheet before opening the picture frame box size guide. It is especially useful when two frames hold the same print but use different mouldings, mats, backing, or hanging hardware.
Keep three sets of dimensions separate
| Record | Measure | Use it for |
|---|---|---|
| Print or artwork size | The artwork dimensions, as a reference identifier. | Identifying the order; this does not establish shipping fit. |
| Finished frame size | The furthest outside edges and the full front-to-back depth. | Documenting the assembled object before protective materials. |
| Protected assembly size | The maximum dimensions after the chosen wrap, corner pieces, and face protection are fitted. | Shortlisting box inside dimensions for a packing trial. |
Measure the finished object at its widest points
Lay the frame where you can measure it without putting pressure on the glazing or artwork. Record the longest outside edge and the other outside edge. For an irregular or decorative frame, find the furthest protrusions rather than measuring only the straight inner rails.
Measure depth from the foremost part to the rearmost part. Include hardware, an easel back, or other components that remain attached for shipment. Describe any removable component separately, and record where it will be packed if removed. Do not let a loose accessory disappear from the package plan simply because it is no longer attached.
Label your measurements clearly: for example, “finished frame, outside, long edge × short edge × depth, inches.” This avoids a common handoff error in which a colleague treats the artwork dimensions as the frame dimensions.
Worked example: one print size, two different frames
In this hypothetical example, two frames both hold an 11 × 14-inch print. Frame A measures 13 × 16 × 1 inch outside. Frame B, with a different mat and moulding, measures 16 × 19 × 1.75 inches outside. The shared print size does not make their shipping requirements interchangeable.
After the packer fits the selected protective materials to Frame B, the complete assembly measures 18 × 21 × 3.25 inches. A hypothetical box with 20 × 18 × 4-inch usable inside dimensions cannot hold that assembly lying flat in the intended orientation: its 20-inch side is shorter than the assembly's 21-inch side.
A larger candidate can move to a physical packing trial, where opening access, closure, and the chosen protection arrangement are checked. The extra space in these measurements is illustrative. It is not a cushioning prescription or proof that the package protects a particular frame.
Measure protection as installed
Corner pieces can extend beyond both the face and the edges. Wrap seams can create a thicker section on the back. A face panel can add depth even if it shares the frame's footprint. Measure the maximum assembled dimensions rather than adding a guessed allowance to the bare frame.
Keep the protective materials in their intended shape during the measurement. A box that fits only when a corner piece is crushed or the lid presses against the glazing is not a successful fit check. Record the source and dimensions of the protection components so the assembly can be reproduced.
Give purchasing a usable specification
Send purchasing the three measurement records, the unit of measure, a photograph showing orientation, the packed component list, and any box opening or assembly constraints. For adjustable or telescoping formats, check the supplier's assembly requirements and the usable space in the assembled sample.
After selecting and testing the complete package, measure its outside shipping dimensions separately. Box inside dimensions answer whether the protected frame fits; outside dimensions describe the closed parcel. Keep both records attached to the same packaging specification.
Review frame box formats and reference sizes using your measured protected assembly, then confirm the exact box specifications before ordering.
