JiaroPack’s Bubble Mailer & Poly Mailer Size Chart

9 mar 2026

At JiaroPack, we make it easy to pick the right mailer size for your orders. Use the charts below to match your product to the correct outer size and, for bubble mailers, the correct usable size.

How to Choose the Right Size?

  • Measure your item’s width and length at the widest points.

  • Add room for thickness (folded apparel, multi item bundles, boxed items).

  • For bubble mailers, choose based on usable size (the padded lining reduces interior space).

Bubble Mailers Size Chart

Bubble mailers are designed for orders that need extra cushioning (cosmetics, small electronics, books, fragile accessories). Each option below includes an outer size and a usable size.

FAQs

What does “usable size” mean for bubble mailers?

Usable size is the interior space available for your item. Because bubble lining takes up space, the usable size is smaller than the outer size.

Why doesn’t the poly mailer chart include usable size?

Poly mailer is organized by outer size and case pack. If you are shipping thicker bundles, size up to allow room for bulk.
