How to Choose the Right Art Shipping Boxes | Sizing And Protection

Choosing the right art shipping boxes depends on the artwork’s size, fragility, and value, with snug cushioning and rigid walls as the baseline standard.

Choosing the right art shipping boxes can feel like a minefield, especially when a single wrong choice could damage a piece you’ve poured weeks into. Whether you’re mailing a small framed print or a large canvas, the correct box prevents costly returns and heartbreak on delivery. Here is how to match the box to the art.

The first step is understanding that there is no universal solution. Your choice hinges on the artwork’s form factor—flat panel, framed glazing, rolled print, or sculpture—not the art’s genre. A watercolor and an oil painting ship differently if one is framed and the other is not.

What Size Box Do You Need For Your Artwork?

Size is the most frequent source of packing errors, and getting it wrong means the cushioning can’t do its job. As a rule, allow about 2 to 3 inches of clearance on every side of the artwork for padding. Some guides go further, recommending the outer box be at least 3 inches larger on all sides than the inner box when double-boxing.

Common box sizes for framed paintings include 28 x 4 x 24 inches, 37 x 4 x 36 inches, and 36 x 6 x 42 inches.

The exact size you need depends on the piece itself, so measure first and never guess. A snug fit that leaves room for foam or paper cushioning—but not so much that the art slides around—is the goal.

Which Box Material And Structure Is Best?

The box’s structure must match the art’s fragility. For unframed flat works and smaller framed pieces, a rigid corrugated box is the standard choice. For anything with glass or a delicate frame, step up to a double-walled, full-overlap slotted box, which provides significantly more crush resistance.

For larger or high-value works, wooden crating is the recommended route. One gallery guide suggests moving to crates for framed art larger than 18 x 24 inches and for large unframed works exceeding 48 x 48 inches. A custom wooden crate offers the rigidity needed to absorb impacts that even double-walled cardboard cannot withstand.

Inside the box, the materials that touch the artwork matter as much as the box itself. Use acid-free or archival materials in direct contact with the surface. Avoid letting bubble wrap touch painted surfaces directly—it can leave impressions or react with the paint. Instead, wrap the art in glassine or acid-free tissue first, then add a protective layer.

How Do You Pack And Protect The Artwork?

Proper packing is a layered process that protects the art from both impact and shifting. For framed pieces with glass, tape an X across the glass with painter’s tape before wrapping. This holds the glass together if it cracks during transit, preventing shards from damaging the frame or the artwork itself. Corner protectors should also be fitted onto the frame’s corners, as these absorb the most impact.

When you are ready to box, use the double-boxing method for valuable works. Wrap the art, place it in a snug inner box with cushioning, then put that box inside a larger outer box. Fill the space between them with at least 3 inches of cushioning on all six sides. This two-layer system is the industry standard for good reason—it isolates the art from the outer box’s direct shocks.

For rolled prints, wrap the tube in padding and secure it inside the box so it cannot roll or slide. With flat pieces, always cushion the bottom of the box, place the wrapped art inside, then fill the remaining space and cover the top before sealing.

How Do You Seal The Box Securely?

The seal is your final line of defense, and it gets skipped too often. Use heavy-duty packing tape and seal all seams along the top and bottom. Saatchi Art recommends the H-taping method for box flaps—run a strip along the center seam and two more strips across the top and bottom edges to form the shape of a capital H. This distributes stress across the flap and resists splitting during rough handling.

If you are sending a framed piece and do not have a suitable box at home, shipping carriers sell specialized options. FedEx offers a framed art box with an Airfloat system in several sizes. The Extra Small fits frames up to 14 x 19 x 2 inches, the Small fits 19 x 24 x 2 inches, the Medium fits 25 x 33 x 4 inches, and the Large fits up to 40 x 50 x 3 inches.

If the artwork is exceptionally fragile or valuable, custom crating is worth the cost. A crate built to the piece’s exact dimensions eliminates shifting entirely and provides unmatched protection against drops and stacking.
