Finding the right packaging for your products doesn’t just make shipping more efficient, it can also reduce damage, cut down on costs, and help you deliver a great unboxing experience. If you’re shipping soft goods like apparel or lightweight accessories, poly mailers are one of the most efficient and affordable solutions.
But with so many sizes available, how do you know which poly mailer size is right for your hoodies, sweatshirts, clothing, or jewelry?
This guide breaks down the best poly mailer sizes by product type to help you streamline your shipping process.
Why Poly Mailers Are Ideal for Apparel and Accessories
Poly mailers are lightweight, waterproof, and tear-resistant, making them a top choice for shipping soft items like clothing and small accessories. Unlike boxes, they don’t add bulk or require filler material. They’re also more cost-effective when it comes to postage and storage.
Poly Mailers for Hoodies
Hoodies are thicker and bulkier than T-shirts or tanks, so they require a slightly larger mailer. For most adult-size hoodies (folded neatly), a 14.5” x 19” poly mailer works well. If the hoodie is oversized or being shipped with other items, consider sizing up to 19” x 24”.
Best size:
14.5” x 19”
19” x 24” (for bulk or multi-item orders)
These sizes allow room for folding while keeping the package tight and professional. For multi-brand sellers or resellers, using poly mailers for hoodies also helps maintain a clean presentation while keeping shipping costs down.
Poly Mailer for Sweatshirt
Like hoodies, sweatshirts are slightly bulky but compressible. A folded medium to large sweatshirt fits snugly into a 12” x 15.5” or 14.5” x 19” mailer, depending on the fabric thickness.
Best size:
12” x 15.5”
14.5” x 19” (for thick or oversized sweatshirts)
If you're shipping a zip-up sweatshirt or fleece, it’s better to go up a size to ensure you’re not overstretching the mailer, which could lead to tearing in transit.
Poly Mailers for Clothing
For general poly mailers for clothing, sizing depends on the garment type:
T-shirts, tanks, or single baby clothes: 9” x 12”
Jeans or dresses: 10” x 13” or 12” x 15.5”
Jackets or multiple items: 14.5” x 19” or 19” x 24”
Clothing is one of the most versatile categories when it comes to poly mailer use. The flexible material makes it easy to pack without adding unnecessary weight or bulk.

Best Mailer Sizes for Jewelry
Jewelry items are small, delicate, and often packaged in small pouches or boxes. For these, consider:
4” x 8” or 6” x 9” poly mailers (ideal for pouches)
9” x 12” mailers (for boxed or gift-wrapped jewelry)
If shipping fragile pieces, insert the jewelry into a bubble-lined pouch or padded mailer for extra protection.

Final Tips for Sizing
Always measure your items after folding or packaging, not flat out.
Leave some wiggle room to avoid stretching or overpacking.
For layered orders, size up to prevent damage during transit.
Use self-sealing mailers with strong adhesive to secure contents.
