How to Choose Mailer Sizes for Framed Prints (2026)
If you've ever opened a package to find a framed print scuffed, bent, or shifted, you know how frustrating returns and refunds can be. This guide is for artists, small-shop sellers, photographers, and office managers who need mailers that prevent shifting and protect framed prints in transit. You'll learn a simple step-by-step method to size mailers correctly and which mailer types solve specific problems (flat prints vs. long posters). Products here were selected for build quality, ability to stop movement, and real customer feedback on sturdiness and sealability.
Quick Answer
Choose a snug, rigid solution: for flat framed prints under 11x14" the Juvale 100-Pack Stay Flat Rigid Mailers 9x11.5 (B08BFB8FT5) is the best overall choice because its 450 gsm board prevents bending and keeps prints from moving. For long posters use a square mailing tube like BOX USA's 25" or 37" tubes; for the tightest budgets pick the Aviditi 25" tube.

Frequently Asked Questions
How much extra space should I allow inside the mailer to prevent shifting?
Allow about 1/4 to 1/2 inch of extra space on each side of a flat framed print so you can add corner protectors and thin foam sheets; for tubes, aim for a snug roll that fills the tube lengthwise with minimal empty space at the ends to stop movement.
Should I use a flat rigid mailer or a tube for framed prints?
Use a flat rigid mailer or a box for framed prints—these prevent bending and protect frame corners. Tubes are best for unframed posters and prints that can be rolled; never roll framed pieces.
What extra packing stops prints from sliding inside a tube?
Use end caps, tightly wrap the roll in kraft paper, add paper filler or crumpled kraft at both ends, and consider a small internal spacer or foam disk so the roll sits firmly against both end caps and doesn't slide.
