Analysis
Outside vs usable size (approximate)
Padded mailers lose space to seams, the flap and the bubble lining. As a rule of thumb, subtract about 1 in from width and 1.5–2 in from length, then subtract item thickness from both. A #2 mailer (8.5 × 11 in outside) comfortably fits a flat item around 7 × 9 in; a 1 in thick item closer to 6 × 8 in. See our mailer sizing guide.
Compatibility notes and common mistakes
A 4 × 6 in label fits on the face of a #2 mailer.
- Buying by outside size for a thick item.
Alternatives
Scotch Flex & Seal Shipping Roll (15 in × 20 ft, FS-1520)
Custom-length wrap for odd shapes.
Final recommendation
A practical default padded mailer size.
