How to post clothes cheaply in the UK: packing, weight and parcel size

Fold small, weigh at home, pick the right parcel size and pack neatly. How to keep postage low for buyers when you sell second-hand clothes in the UK.

The cheapest way to post clothes in the UK is to send them in the smallest, lightest parcel that protects them: fold tightly, use a mailing bag rather than a box for soft items, weigh the packed parcel on kitchen scales, and choose the parcel size that matches. Most single garments are light, so it is usually the size and weight band you pick, not the piece itself, that decides the postage.

When you sell on Rewear, the buyer pays for delivery at checkout and you print a prepaid label from the app, so you never buy your own postage. But the parcel size you choose still matters, because it decides what the buyer pays, and a lower postage price makes your piece more tempting.

Rewear's four parcel sizes

When you list a piece on Rewear you choose one of four parcel sizes. Each has a weight limit and a rough guide to what fits.

The buyer chooses a delivery option at checkout from the ones available for that size, so a smaller size usually means cheaper delivery for them.

Weigh before you list

Guessing is where most sellers end up overpaying or underpaying.

  1. Fold the piece as you will post it, with the packaging you plan to use.
  2. Weigh it on kitchen scales or bathroom scales. For bathroom scales, weigh yourself holding the parcel, then without it, and take the difference.
  3. Pick the smallest parcel size whose weight limit is comfortably above the figure.

Leave a little margin. A parcel that is only just under a limit on your scales may not be under it on a carrier's.

Fold small, pack light

Most clothes do not need a box. A box adds weight and size, and soft garments travel perfectly well in a bag.

Shoes, boots and bags

Footwear is heavier and needs to keep its shape.

Posting several pieces together

On Rewear a buyer can buy several pieces from the same seller as a bundle. A bundle travels as one parcel, so postage is charged once rather than for each piece, and the parcel size is worked out from the sizes of everything in it. That is one more reason to choose each piece's parcel size accurately when you list.

Label and drop-off

Once a piece sells, the prepaid label comes from the app. Where you take the parcel depends on the delivery option the buyer chose. Some options go from lockers or parcel shops and some from a Post Office, and the order tells you which. Post within five days of the sale, and keep your proof of posting until the buyer confirms the piece has arrived.

If you cannot post in time, cancel the order in the app so the buyer is refunded straight away rather than left waiting.

Packing that prevents problems

A careful parcel is also your best protection.

A tracked parcel that goes missing in transit is dealt with by Rewear with the carrier, and the seller is not out of pocket as long as they used the Rewear label and posted on time. Our guide to buying second-hand safely explains more.

The short version
