Fanfold stacks, rolls and small stock labels compared by size, printer fit and cost per label, for sellers printing their own postage.
Almost every UK postage label you buy online comes out at 100 × 150 mm, often called 4 × 6 inches. A thermal printer burns that onto heat-sensitive paper, so you buy no ink or toner.
Pick by format. Fanfold stacks hold 500 labels for about £12 to £18, rolls hold 250 for about £8 to £13, and a roll of small 40 × 30 mm labels covers shelf codes and bag notes.

Each step in the order you'll need it.
Fanfold labels come as a flat zigzag stack that sits behind the printer and feeds through a slot. You get more labels per pack and fewer swaps in a busy week.
Rolls sit on a holder inside or on top of the printer. They suit a small desk, or a printer with no rear slot, and cost a little more per label.
Buy 100 × 150 mm for postage. Royal Mail Click & Drop, eBay, Vinted and Evri all offer a label layout at that size, so the address and barcode print at full scale.
Avoid smaller shipping labels unless your printer can only take narrow rolls. A shrunk barcode can fail to scan at the depot.
Kit for this step
Most desktop thermal printers take generic labels up to about 108 mm wide, on rolls or fanfold. Check two numbers in your printer's manual: maximum label width and maximum roll diameter.
Some compact printers only accept the maker's own chipped rolls. If yours does, generic labels will not feed, so factor that cost in before you buy the printer.
Home printers are direct thermal: no ribbon, and the label darkens where the head heats it. Buy labels marked direct thermal.
Thermal transfer labels need a ribbon and print blank on a direct thermal printer. They are easy to buy by mistake from bulk listings.

100 × 150 mm, sometimes sold as 4 × 6 inch. Click & Drop has a layout for that size.
Usually, per label. Our typical bands put 500 fanfold at £12 to £18 and 250 on a roll at £8 to £13.
Most desktop thermal printers take them. A few compact models need the maker's own rolls, so check the manual first.
You may have thermal transfer labels, which need a ribbon. Scratch the label with a fingernail: direct thermal paper turns dark.
Heat and sunlight darken or fade them over months. That is fine for postage, but store spare stock somewhere cool.
