Bubble Mailer Size Chart (#000 - #7)
Direct answer: choose a bubble mailer by measuring the finished item, then leaving room for padded seams and closure. Use the smallest mailer that loads cleanly without crushing the item or letting it slide around inside the mailer.
Bubble Mailer Size Chart Framework
| Mailer family | Common outside size signal | Best starting use case |
|---|---|---|
| #000 | About 4 x 8 | Cards, jewelry boxes, small accessories, and light parts. |
| #0 | About 6 x 10 | Small ecommerce items, cosmetics, compact kits, and soft accessories. |
| #1 | About 7.25 x 12 | Small books, compact boxed goods, and folded soft goods. |
| #2 | About 8.5 x 12 | Larger accessories, documents with padding, and common marketplace orders. |
| #7 | About 14.25 x 20 | Larger padded shipments, folded apparel, catalogs, and bigger soft goods. |
How To Choose A Bubble Mailer Size
- Measure the finished item: include sleeves, bags, inserts, retail packaging, and any rigid backing.
- Allow for padded seams: usable inside space is smaller than the outside mailer size.
- Check closure room: leave enough space for peel-seal, tear strip, tape, or label workflow.
- Test flex risk: switch to a box when the item is rigid, crush-sensitive, sharp-edged, or heavy.
- Compare one size up: if loading is tight, compare the next mailer size before making it a repeat route.

Material And Protection Checks
- Kraft bubble mailers: useful for common padded ecommerce shipments and simple presentation.
- Poly or metallic bubble mailers: compare when moisture resistance, color, or presentation matters.
- Insulated bubble mailers: inspect when the job has thermal or perishable handling requirements.
- Boxes: use corrugated boxes instead of mailers for rigid, sharp, crush-sensitive, or high-value goods.
