Frequently Asked Questions
What board thickness (gsm) is best for shipping flat framed prints?
For single flat prints, aim for 350–450gsm for reliable stiffness; smaller postcard-type items can use 300–350gsm. For framed or heavy pieces, choose double-wall or add additional stiffeners (cardboard backing, corner protectors) to prevent bending.
Should I use self-seal mailers or reinforce with tape?
Self-seal mailers are quick and usually secure, but adhesive quality varies. For valuable prints or longer transit, reinforce the flap with a strip of packing tape or use a tab-lock closure for reusability and added security.
How can I keep postage costs reasonable while protecting my prints?
Pick the lightest mailer that still provides adequate protection—expandable or crush-resistant designs can avoid heavy double-boxing. For larger or bulkier items, optimize by removing unnecessary padding, adding just enough stiffeners, and comparing regional mailing rates for flat vs. parcel pricing.
