Mailing Bags for Clothes: Which Size for T-Shirts, Hoodies and Coats

Mailing bags for clothes are opaque polythene bags with a self-seal strip, and the right size depends on how thick the garment is once folded as well as its width and length. The garment sizes in this article are approximate starting points, so measure your own folded item before you order.

Pack Solution stocks grey, white and hot pink bags for clothing, plus clear OPP bags to keep a garment clean inside the parcel. The bags are lightweight, which helps keep postage costs down, and the opaque film keeps lingerie, swimwear and gifts private.

Clothing Mailing Bags: Which Size for Which Garment

As an approximate guide, a folded T-shirt or dress starts at 10 x 14" (250 x 350mm), knitwear and trousers at 12 x 16" (305 x 405mm), and jackets at 14 x 20" (355 x 510mm). Coats and multi-garment orders need 17 x 22" (430 x 560mm).

Smaller Garments and Accessories

The 9 x 12" (230 x 300mm) size is the smallest in the white and hot pink ranges. It suits lingerie sets, swimwear, makeup bags and hair accessories, and it also takes an A4 sheet (210 x 297mm) flat. Grey goes smaller, down to 4 x 6" (100 x 150mm), for accessories.

T-Shirts, Dresses and Jumpers

A folded shirt, dress, top or pair of pyjamas is an approximate fit for the 10 x 14" (250 x 350mm) bag. Knitwear and trousers are bulkier when folded, so they start one size up at 12 x 16" (305 x 405mm). Grey also has 13 x 19" (330 x 485mm) and 14 x 21" (350 x 525mm) if a thick fold needs more room.

Hoodies, Jackets and Coats

Bulkier garments need the larger sizes. Hoodies and loungewear sets sit in the 12 x 16" (305 x 405mm) bag, while jackets, heavier knitwear and bulky jumpers move up to 14 x 20" (355 x 510mm). For coats, throws and orders with several garments, the 17 x 22" (430 x 560mm) bag is the largest in the white and hot pink ranges. Grey goes further, to 34 x 42" (850 x 1050mm).

Postage Bags for Clothes: Grey, White or Hot Pink

Grey is the discreet choice. The grey mailing bags use opaque grey polythene, so nobody can see what is inside the parcel, and they come in the most sizes. The white mailing bags have a clean white finish that works with any logo, sticker or label, and a white surface shows a handwritten address clearly. The hot pink mailing bags are a loud, vivid shade that suits fashion and beauty brands.

The white and hot pink bags share a self-seal strip with a 50mm lip and a tamper evident seal that is difficult to open once closed. Clothing postage bags in either colour are sold in packs of 100 for each of the five sizes.

Sellers on eBay, Etsy and Vinted use these bags to send clothing, and a recognisable colour helps a small brand stand out. White and grey keep the look plain. Hot pink makes the parcel easy to spot on the doormat and suits lingerie, beauty, fashion and gift orders.

How to Bag a Garment Step by Step

Fold the garment, check it against the bag, then seal and label it.

1. Fold the garment to the shape it will travel in, and flatten any bulk such as a hood.
2. Measure the folded width and length, and allow a little extra for thickness so the seal lies flat.
3. Pick the bag size just above those measurements. Sizes are width x length.
4. If the garment needs to arrive clean and presentable, slide it into a clear OPP bag first.
5. Place the garment in the mailing bag, peel the backing off the adhesive strip and press it down along its full length.
6. Add the address label to the outside of the bag.

Our guide to how to package clothes for online orders has more on folding and presentation. If you are unsure between two sizes, order a single pack of each and test them with your own stock.

Keeping Clothes Private and Dry

Opaque mailing bags hide the garment, and the outer is water resistant, so contents are protected from rain in transit. Water resistant is not waterproof, so press the whole strip down before posting.

That matters most for lingerie, swimwear and gifts, where nobody should be able to see inside. The white and hot pink bags also have a tamper evident seal, which is difficult to open without leaving a sign.

Clear OPP Bags as Inner Garment Bags

Clear OPP bags are crystal clear polypropylene bags that keep a folded garment clean and dust free inside a mailing bag or box. The garment arrives neatly presented when the parcel is opened.

The transparent OPP bags come in 10 sizes. The 10 x 14" (254 x 355mm) to 14 x 17" (355 x 432mm) sizes suit folded T-shirts and light garments, and the 15 x 20" (381 x 508mm) and 18 x 22" (458 x 560mm) sizes suit bulkier folded clothing and soft goods. OPP stands for oriented polypropylene.

Transparent OPP Bags

Crystal clear polypropylene bags in 10 sizes that keep folded clothing clean and dust free inside a mailing bag or box.

• 10 sizes, 6.5 x 9" (165 x 230mm) to 18 x 22" (458 x 560mm)
• Pack of 100 per size
• Glossy, high clarity finish

Choose a mailing bag at least one size up from the OPP bag so the strip closes cleanly over it. The comparison of polythene bags and OPP bags compares the two.

Mailing Bags or Boxes for Clothes?

Clothes are soft and non-fragile, so postal bags for clothes are usually enough. Boxes earn their place when a garment must keep a shape or sits alongside breakable items.

Mailing bags add very little weight to a parcel. They suit clothing, textiles and other soft goods, and sellers on eBay, Etsy and Vinted use them for exactly that. A bag gives no crush protection, so a boxed or rigid item inside needs its own care. If a parcel combines clothing with something breakable, the box is the safer choice. The parcel bags guide covers the wider size range, including the large mailing bags used for bedding.

Ordering Mailing Bags for a Clothing Business

Bags are priced per pack, ex VAT, and the price per pack falls as you add more packs. Volume pricing is shown on each product page.

A clothing range rarely needs one size. Add packs of different sizes to the same order, for example 10 x 14" (250 x 350mm) for tops and dresses and 12 x 16" (305 x 405mm) for knitwear and hoodies, so each garment gets a bag that closes without strain. If a size turns out wrong for a new line, order a single pack of the next size to test it before committing to more.

Pack counts differ by product: grey comes in packs of 100 up to 17 x 24", 50 from 20 x 26" to 28 x 34", and 25 at 34 x 42". White, hot pink and OPP bags are all packs of 100 per size. Orders placed by 2pm Monday to Friday are dispatched the same working day, and Royal Mail Tracked 48 is free on every order with no minimum. The shipping policy lists the Express and DPD options, and unused items can be returned within 30 days of delivery under the refund policy.

Clothing Bag Checklist

• Fold the garment the way it will be posted.
• Measure the folded width and length, and treat the garment sizes in this article as approximate.
• Pick the bag size just above the measurement.
• Choose grey for discretion, white for a neutral look or hot pink for a branded parcel.
• Add a clear OPP bag if the garment must arrive clean.
• Use a box if the parcel includes anything fragile.

Choosing Your Clothing Mailing Bags

Work from the folded garment: 10 x 14" for a shirt or dress, 12 x 16" for knitwear, 14 x 20" for a jacket and 17 x 22" for a coat, then check the fit against your own stock. All the bags, in every colour and size, are in the bags collection.

Frequently Asked Questions

What size mailing bags for clothes should I use for a T-shirt?

As an approximate guide, a folded T-shirt or shirt starts at 10 x 14" (250 x 350mm), available in grey, white and hot pink. Fabric thickness and folding change what fits, so measure your folded garment and pick the bag just above it.

Which postage bags for clothes suit a hoodie?

A folded hoodie or loungewear set is an approximate fit for the 12 x 16" (305 x 405mm) size in White Mailing Bags or Hot Pink Mailing Bags. Grey Mailing Bags also come in 12 x 16". Thick hoods can push you up to 14 x 20" (355 x 510mm).

Are clothing mailing bags see-through?

No. Grey, white and hot pink mailing bags are opaque polythene, so nobody can see the garment inside, which matters for lingerie, swimwear and gifts. Clear OPP bags are transparent, so they are used as inner bags inside a mailing bag rather than on the outside.

What is the biggest bag for a coat?

Hot Pink Mailing Bags and White Mailing Bags go up to 17 x 22" (430 x 560mm), which suits coats, throws and orders with several garments. Grey Mailing Bags go larger, to 17 x 24" (425 x 600mm) in packs of 100 and up to 34 x 42" (850 x 1050mm) in packs of 25.

How many clothing postage bags come in a pack?

White and Hot Pink Mailing Bags come in packs of 100 for every size. Grey Mailing Bags come in packs of 100 up to 17 x 24" (425 x 600mm), 50 from 20 x 26" to 28 x 34", and 25 at 34 x 42". Prices are per pack, ex VAT.

Can I put a clear OPP bag inside a mailing bag?

Yes. Transparent OPP Bags keep clothing clean and dust free inside a mailing bag. The 10 x 14" (254 x 355mm) to 14 x 17" (355 x 432mm) sizes suit folded T-shirts and light garments. Choose a mailing bag at least one size larger so the strip closes cleanly.
