How to Choose the Right Size and Lining for a Padded Envelope
Match your product to the right padded envelope size and cushioning type.
Standard sizes
Quick answer
Choose the smallest size that fits your product with 10-20mm clearance per side. For lining, paper-padded is best for recyclability, bubble-lined for maximum cushioning, and foam-lined for electronics. The envelope should fit snugly around the product - too loose allows movement damage, too tight prevents the seal from closing properly. Check total packed dimensions against postal size bands.
Lining types
Traditional choice for fragile items. Not recyclable through kerbside.
Corrugated or tissue paper lining. Comparable protection for most items.
Specialist option for electronics and static-sensitive components.
Excessive padding adds postage weight and cost without proportional protection gains.

Postage considerations
Padded envelopes add thickness and weight. A size D (180x265mm) may fit within large letter dimensions but the padding pushes thickness close to the 25mm limit. Always measure the packed, sealed envelope to confirm it fits your intended postal category.
