The guide
Each step in the order you'll need it.
Who uses small thermal labels
Small labels suit you once you keep more stock than you can remember: rails of tagged vintage clothing, boxes of graded slabs, or a storage-unit haul sorted into bins.
A 1,000 roll lasts a home seller a long time. Labelling twenty new items a day, you get around seven weeks of use, and stock bins and shelf codes barely dent it.
Label size, core and printer fit
Each label is 40 by 30 mm, big enough for a stock code, a short title and a barcode or QR code. See whether your printer software lists 40 by 30 mm as a preset or lets you set a custom size.
Choose direct thermal labels, which need no ribbon, on the core size your printer takes. Many 4 inch shipping printers have an adjustable guide that closes in for narrow rolls, but the manual gives the minimum label width.
Permanent adhesive suits stock boxes and bins. Choose removable adhesive for anything you stick straight onto an item, a sleeve or a garment tag.
Setting up a stock code system
Pick a short code pattern, such as a letter for the shelf and a number for the bin, and print it once on the bin and again on each item inside. Put the same code in your listing's SKU field, so each sale shows you where to look.
Load the roll, run the printer's calibration so it finds the gaps, then print one test label. Adjust the darkness until barcodes scan cleanly from your phone.
Keep the roll away from heat and direct sun near your bench. Direct thermal labels darken in heat, so anything stored for months belongs in a cool cupboard.
Shipping-size labels, a narrow-roll printer or an app
100 x 150 mm thermal labels, 250 roll, are the fallback and the size for shipping labels. You can print stock codes on them, though most of the label goes to waste.
100 x 150 mm thermal labels, 500 fanfold, suit busy shipping days and feed from a box behind the printer. If your main printer won't take narrow stock, run this roll in a narrow-roll label printer such as the Phomemo thermal label printer.
Sortly can generate the codes and QR labels for you if you would rather manage stock in an app.
Under a penny a label, reprinted yearly
At £8 to £12 for 1,000, each label costs about a penny, so you can label every item, bin and shelf without counting.
Direct thermal print fades over months, faster in sunlight. Reprint bin labels once a year or when a scan fails, and use a printed paper label for anything that must last for years.
Common mistakes
Each one costs you money or reviews, and each has a fix.
- Close the printer's guides against the roll edges; without them a narrow roll wanders and prints off the label.
- Without gap calibration the printer splits codes across two labels. Run it each time you change size.
- Permanent labels leave residue on items and card sleeves, so buy removable adhesive for anything a buyer receives.
- Raise the darkness and test one label: barcodes printed too light won't scan on a phone.
- A hot loft or a sunny window fades the print on labelled stock; keep it somewhere cool and shaded.

Questions
Will a 40 x 30 mm roll fit my shipping label printer?
Many 4 inch printers accept narrow rolls with adjustable guides, but some have a minimum label width. Your printer's manual lists its supported sizes.
Do I need ink or a ribbon?
No. These are direct thermal labels, so the printer's heated head darkens the coating. Ribbons are for thermal transfer stock.
Can I print shipping labels on these?
Carrier labels are designed for 100 by 150 mm. Keep this roll for stock codes, bin labels and notes.
How long does the print last?
Months indoors, less in heat or sunlight. Reprint any code that fades or will not scan.
Can I stick these on clothing?
Put them on a swing tag or a bag. Labels stuck straight onto fabric can leave adhesive behind.
