Overview

Padded mailers are bubble-lined and cushion-lined envelopes for shipping small, semi-fragile items without a box: white self-seal bubble mailers in the standard #000 through #7 sizes, plus puncture-resistant padded mailers, in 25-packs and 50 or 100 count cases. They protect against scuffs and light impacts while keeping the package thin and light, which is the whole point of skipping a carton. For a worked example, how to ship trading cards shows when a bubble mailer is enough and when the card needs a rigid holder inside.

Standard sizes, decoded

Mailer numbers are an industry shorthand for envelope dimensions. Interior room is smaller than the listed size because the bubble lining and seal flap take up space, so size to your item plus about half an inch each way.

Size Dimensions Typical contents
#000 8x4 in Small accessories, cables, cosmetics
#00 5x10 in Jewelry boxes, small electronics
#0 6x10 in Phone cases, small parts
#1 7.25x12 in DVDs, paperbacks, folded apparel
#2 8.5x12 in Books, tablets in their retail box
#3 8.5x14.5 in Larger books, document stacks
#4 9.5x14.5 in Apparel, boxed goods; also available as a puncture-resistant padded mailer
#5 10.5x16 in Multiple items, bulkier soft goods
#6 19x12.5 in Large apparel, throw pillow covers
#7 14.25x20 in The largest common mailer format

When a padded mailer is the wrong call

  • Rigid flats: photos, prints, and collectibles need a stayflats mailer, not padding. See rigid mailers for shipping comic books.
  • Crush-sensitive items: bubble lining absorbs scuffs and light impacts, not stacking pressure. Anything that cannot take weight on top belongs in a corrugated box from shipping boxes.
  • Non-fragile soft goods: if the item needs no cushioning at all, a plain poly mailer from poly mailers is lighter and cheaper to run.

Freight is part of the price

Mailers are one of the more freight-efficient things we sell because cases pack flat, but the honest math still holds: on a small order, freight can rival the product cost. The fix is the same as everywhere else in packaging. Buy the case count instead of the 25-pack once a size proves out, and combine mailers with your tape and label order. The packaging cost and cube index shows how each format converts to billable cube.

Buying path

Buy Padded Mailers by the specs that change the order

Use filters, product titles, and product pages to compare size, material, pack count, case quantity, and fit before ordering.

Compare

Use filters and product titles to narrow by the specs that affect fit.

Confirm

Open the product page before ordering a case so you can check quantity, unit, and limits.

Reorder

Save the SKU or product link for repeat purchasing and support questions.

Larger orders

For pallet, recurring, or mixed-SKU needs, send support the details before placing a large order.

What to check first

  • Usable inside size
  • Padding or material
  • Closure type
  • Case quantity
Common wrong-order risk: Forgetting item thickness. A mailer that fits flat dimensions can still be too tight once the product is packed.
