Fanfold stacks, rolls and small stock labels compared by size, printer fit and cost per label, for sellers printing their own shipping labels.

About this ranking

Almost every US shipping label you buy online prints at 4 × 6 inches, from eBay, Pirate Ship, Poshmark, Mercari or USPS Click-N-Ship. 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 $20, rolls hold 250 for about $8 to $14, and a roll of small 1.5 × 1 inch labels covers shelf codes and bag notes.

The guide

Each step in the order you'll need it.

01

Fanfold or roll

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.

02

Getting the size right

Buy 4 × 6 inch labels for shipping. eBay, Pirate Ship, Etsy and the Poshmark and Mercari prepaid labels all print at that size, so the address and barcode come out at full scale.

Avoid smaller shipping labels unless your printer only takes narrow rolls. A shrunk barcode can fail to scan at the post office or sorting center.

03

Checking printer compatibility

Most desktop thermal printers take generic labels up to about 4.25 inches 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.

04

Direct thermal, not transfer

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.

Questions

Straight answers to what sellers ask about this.

What size thermal labels do I need for USPS?

4 × 6 inches. Pirate Ship, eBay and USPS Click-N-Ship all offer a 4 × 6 layout.

Are fanfold labels cheaper than rolls?

Usually, per label. As a rough guide, 500 fanfold run $12 to $20 and 250 on a roll $8 to $14.

Will generic labels work in my printer?

Most desktop thermal printers take them. A few compact models need the maker's own rolls, so check the manual first.

Why are my labels printing blank?

You may have thermal transfer labels, which need a ribbon. Scratch the label with a fingernail: direct thermal paper turns dark.

Do thermal labels fade?

Heat and sunlight darken or fade them over months. That is fine for a package in transit, but store spare stock somewhere cool.

Can I print Poshmark labels on a thermal printer?

Yes. The Poshmark prepaid label comes as a PDF you can print at 4 × 6 inches. Mercari and Depop labels work the same way.
