eBay shipping labels: printing 4×6 from an iPhone

eBay can produce 4×6 labels for some postage services, but not all of them. Here’s how to get a clean 4×6 label either way, using just your phone.

How eBay postage labels work

When you sell on eBay in the UK, you can buy postage through eBay and print the label from your orders. eBay’s help explains how to buy and print labels, and mentions that you can fit labels onto a single sheet of A4 to save paper.

Whether you can also pick a 4×6 format depends on the postage service and the way you’re buying it. Sellers on eBay’s community forums report that a 4×6 option is available for some services and not for others, and that the setting has moved around over time.

Use eBay’s 4×6 option if you have one

Before you buy the label, look for a label size or print format choice on the postage page or in your postage label preferences. If 4×6 is offered for the service you’re using, choose it. You’ll get a label that’s already the right shape for a thermal printer, and you won’t need to crop anything.

Because eBay changes its pages from time to time, we won’t list exact menu names here. eBay’s own help pages and community board are the best places to check the current steps.

When the label only comes as A4

If you’re only offered A4, or the 4×6 setting has reset itself, you can still print to a thermal printer. The label is on part of the A4 page, so you just need to cut it out digitally.

  1. Buy and download the label as normal. On iPhone, when the PDF opens, use the share option to save it to Files. If you’ve emailed it to yourself, save the attachment to Files.
  2. Open Label Fixer and import the eBay label from Files, or choose a screenshot or photo from Photos.
  3. If the PDF has more than one page, pick the page with the label on it.
  4. Label Fixer finds the label and crops it to a portrait 4×6 inch PDF. Check the preview: the address, barcode and any QR code should all be inside the crop.
  5. If the crop has picked up too much, such as printed instructions beside the label, tap Edit Label. Move or resize the crop so it sits around the label, and rotate it if the label is sideways.
  6. Share the finished PDF to your printer’s own app, or save it to Files, send it by Mail or AirDrop it to a computer that’s connected to the printer.

Some label pages include a packing slip, or two labels side by side. If the automatic crop takes in more than one label, or the slip as well, tap Edit Label and resize the crop around the one you need.

  • Choose 4×6 inch (sometimes listed as 6×4, or 100 × 150 mm) as the paper or label size in your printer’s app.
  • Print at actual size or 100%. Avoid “fit” or “scale” options unless your printer’s instructions say otherwise.
  • Do one test print when you set up a new printer or a new roll, and check the barcode is sharp, complete and not cut off at the edges.

If you print from a computer, AirDrop or save the PDF across and print it from there. Some sellers report that labels come out sideways or on the wrong page size when the computer’s printer settings don’t match the label stock, so set the paper size to 4×6 in your printer settings too.

International parcels and customs forms

Labels for international parcels can include customs paperwork, and these may come as separate pages. Pick the page you need when Label Fixer asks, and check that anything that has to travel with the parcel is printed and attached. If in doubt, follow eBay’s instructions for that service.

Keep a copy handy

Every label you finish is saved in Label Fixer’s History on your device, with no account and no uploads. Reopen it if a print fails. With Pro, a one-time purchase, you get unlimited labels, full history and bulk export from History.
