How to Design a Custom Mailer Box
Design around the product, then around the opening.
Define the fit
Start with contents, orientation, protective material and internal dimensions. Confirm the structure before placing artwork.
Plan each surface
Use the outside for recognition and shipping needs. Keep inside messages concise and avoid putting critical text across folds or glue areas.
Review a physical sample
Check fit, assembly, readability and color together. Confirm the sample type and how closely it represents the final production specification.
