Poly mailer size guide
Picking the right poly mailer (courier bag) size keeps packages neat and can lower your shipping fee, since couriers often charge by size and weight. Here's what fits in each of our six sizes.

|---|---|---|---|
| XS | 20 × 30 cm | 7.9 × 11.8 in | Jewelry, accessories, cosmetics, phone cases |
| S | 25 × 35 cm | 9.8 × 13.8 in | A folded t-shirt, scarves, small items |
| M | 28 × 42 cm | 11 × 16.5 in | Tops, leggings, light apparel, two shirts |
| L | 32 × 45 cm | 12.6 × 17.7 in | Sweaters, dresses, small bundles |
| XL | 38 × 52 cm | 15 × 20.5 in | Hoodies, jeans, multi-item orders |
| JUMBO | 45 × 60 cm | 17.7 × 23.6 in | Jackets, bedding, bulky or bundled items |
How to measure your item
- Fold or pack the item the way you'll ship it, and lay it flat.
- Measure its width and length in centimeters.
- Add a few centimeters to each side for the item's thickness, so the bag closes without stretching.
- Pick the smallest size that fits. If you're between two sizes, or the item is thick, go one size up.
Tips for online sellers
- Don't oversize. A snug mailer looks neater, protects better, and keeps courier fees down.
- Stock two or three sizes. Most clothing shops do well with S, M and XL.
- Use color for your brand. A consistent mailer color makes unboxing photos instantly recognizable.
- Seal properly. Peel the liner, fold the flap, and press firmly along the whole adhesive strip.

What size poly mailer fits a hoodie?
A folded hoodie or pair of jeans usually needs XL (38×52 cm). Use JUMBO (45×60 cm) for jackets or bundles.
Is the size measured with the flap?
Sizes are width × length of the usable pouch. Measure your item flat and leave a few centimeters of room for its thickness.
