How to choose

  • Measure your item and add room for fold, padding, or label.
  • If both fit, the smaller/thinner option ships cheaper; size or gauge up for thick, heavy, or sharp contents.
  • Use the bulk quote path for recurring or mixed-SKU orders.

Should I choose 9x12 or 7.5x10.5 Poly Mailers?
Pick the smallest size / lightest gauge your item fits without forcing the seal. Both are stocked above with live pricing.
What should I do when a field is not listed?
