Mailer box size calculator
Inside size for an e-commerce mailer box around your product and padding.
How it works
Inside size = product size + padding on both sides of every dimension. Outside size adds the board thickness.
Tip
Keep mailers shallow: height drives dimensional weight on wide, flat boxes.
Questions
Which board for mailers?
E-flute is the usual choice: thin, strong and printable. B-flute for heavier products.
Do mailers need tape?
Self-locking (roll end tuck front) mailers close without tape; a tear strip or sticker adds tamper evidence.
