Choosing the right Vinted shipping bags is the secret to getting 5-star reviews and keeping your postage costs low.
If you’ve started selling on Vinted or Depop, you quickly realize the hardest part isn’t the “drop” — it’s the shipping. Using a bin bag and a roll of sellotape might work once, but if you want those 5-star reviews and repeat buyers, professional packaging is a must.
But what size do you actually need? At Packaging365, we’ve narrowed it down to the three “Essential” sizes that cover 99% of everything sold on Depop and Vinted.
1. The Best Vinted Shipping Bags for Single Items (9″ x 12″)
Perfect for: Summer Drops & Thin Layers
The 9×12″ A4 large letter sized bag. Ideal for: Single T-shirts, summer dresses, and jewelry.”
This is the “Bread and Butter” bag for any casual reseller. If it’s light and thin, this is your go-to for:
- Vinted/Depop Staples:
- T-shirts, vests,
- summer dresses,
- skirts, thin leggings,
- a single pair of shorts,
- jewellery and accessories
💡 MONEY SAVER: These 9×12 bags often qualify for Royal Mail Large Letter rates.
The “Pro” Hack: If you fold your item flat, this bag usually stays under 2.5cm thick. This means you can ship via Royal Mail Large Letter instead of a full parcel—saving you (or your buyer) a couple of quid!
Check the Royal Mail Large Letter dimensions to ensure your parcel qualifies.
2. The “Hoodie & Jeans” Bag: 12″ x 16″
Perfect for: The Standard “Small Parcel”
The 12×16″ is the most versatile bag for Depop & Vinted sellers. Fits hoodies, jeans, and most trainers.
This is the most essential bag in the game. Most things sold on Depop fit in here. If you are only going to buy one pack of bags to start your shop, make it this one.
- Vinted/Depop Staples: Hoodies, sweatshirts, jeans, cargo pants, chunky knitwear, or a standard pair of trainers (out of the box).
- Why it’s the GOAT: It fits perfectly within the “Small Parcel” dimensions for Evri, Yodel, and Royal Mail. No surcharges, no stress.
3. The “Bundle” Bag: 16″ x 21″
Perfect for: Big Winter Sales & Multi-Buys
Don’t cram it! Use the 16×21″ bag for heavy winter coats and multi-item bundles.
Vinted buyers love a bundle discount. When someone buys 5 items from your shop at once, you’re going to need something bigger than a standard mailer.
- Vinted/Depop Staples: Puffer jackets, heavy overcoats, boots (in the box), or bundles of 3-5 items.
- The “Review” Saver: Don’t try to cram a huge coat into a medium bag. It stretches the plastic, makes the parcel look messy, and can lead to the seal popping open. Use the 16×21 for a professional look that gets you that “Great Packaging” feedback tag.
Quick Reference Cheat Sheet
| If you’re selling… | Use this bag size: |
| A vintage T-shirt or Crop Top | 9″ x 12″ |
| Baggy Jeans or a Hoodie | 12″ x 16″ |
| A Shoebox or Trainers | 12″ x 16″ |

Don’t Forget the Tape!
Nothing ruins a “professional” vibe like masking tape or clear tape that peels off. If you’re shipping heavy jeans or bundles, use our Heavy Duty Clear Tape to ensure that “Peel and Seal” strip is extra secure.
The Clear tape is also good for ensuring that your address label stays firmly fixed to your parcel.
Final Wrap-Up: Ship Smarter, Not Harder
Choosing the right packaging isn’t just about logistics—it’s about protecting your seller reputation and keeping your shipping costs low. By matching your items to the correct bag size, you avoid split seams, messy parcels, and unexpected courier surcharges.
- 9″ x 12″: Your go-to for light layers and Large Letter savings.
- 12″ x 16″: The versatile “must-have” for hoodies, jeans, and trainers.
