Labels & Tags
Pick the right label for your printer, surface, and workflow
Choosing labels is about three things: the printer you have, the size and stock the workflow needs, and the surface or condition the label has to survive. Get any of those wrong and you get smeared barcodes, peeling adhesive, jammed printers, or labels that don't scan at the carrier.
Use this guide to route between thermal shipping labels, address and barcode labels, fragile and hazmat warning labels, and blank vs printed stock by size and printer.
Thermal Shipping Labels
The common format for ecommerce shipping. 4 x 6 in labels work with many shipping platforms and thermal label printers.
Address & Barcode Labels
Sheet-fed and roll labels for office printers, inventory tagging, and warehouse barcoding. Common sizes include 1x2-5/8, 2x1, and 2x4.
Fragile, Hazmat & Warning
Pre-printed safety and handling labels: Fragile, This Side Up, Glass, Heavy, limited quantity, ORM-D, and lithium battery labels. Match any hazmat label to the exact shipment and applicable carrier rules before use.
Direct thermal vs thermal transfer
| Attribute | Direct Thermal | Thermal Transfer |
|---|---|---|
| How it prints | Heat darkens chemically treated label face. No ribbon. | Heat melts a wax or resin ribbon onto the label. |
| Print durability | Fades with heat, sunlight, and friction over months. | Long-lasting, scratch and chemical resistant. |
| Best for | Shipping labels used within a few months. | Asset tags, cold storage, outdoor, long-life barcodes. |
| Cost per label | Lower (no ribbon). | Higher (ribbon consumable). |
| Common printers | Zebra ZD230/ZD420, Rollo, Munbyn, Dymo LabelWriter. | Zebra ZT230, Zebra ZD621, industrial Datamax. |
Sizes that matter
4 x 6 in - Common shipping-label size for thermal printers. Ships on rolls or fanfold.
2-5/16 x 4 in - Dymo LabelWriter shipping size (1744907 / 30256 compatible).
1 x 2-5/8 in - Avery 5160 / 8160 address label, 30 per US Letter sheet.
2 x 1 in & 1 x 2 in - Inventory and barcode labels for shelf and bin tagging.
2 x 4 in - Pallet, case, and shipping label for larger SSCC barcodes.
Roll vs fanfold
Rolls are the default for desktop thermal printers (Rollo, Munbyn, Zebra ZD230). They sit on a holder behind the printer or load on an internal spindle.
Fanfold stacks behind the printer in a folded block, feeds without a roll holder, and is faster to swap on high-volume benches. Most desktop thermal printers accept fanfold through a back slot.
If you ship more than ~200 labels a day, fanfold usually pays back in fewer reload stops.

Labels FAQ
What size shipping label should I check first?
Start with 4 x 6 in for thermal shipping labels unless your shipping platform, printer, or carrier workflow requires another size. Both rolls and fanfold work when the printer accepts the stock format.
Direct thermal or thermal transfer for shipping?
Direct thermal is fine for shipping labels you'll ship within a few months. Pick thermal transfer if labels need to survive heat, sunlight, cold storage, or chemicals - asset tags, drum labels, outdoor barcodes.
Will Zebra labels work in a Rollo or Dymo?
Generic 4 x 6 in direct thermal labels work in Rollo and most Zebra desktop printers. Dymo LabelWriters use Dymo-specific stock (1744907, 30256, 30252) - generic 4 x 6 rolls won't load.
Do I need fanfold or roll?
Roll is the default for low-volume desktops. Fanfold is faster to reload and feeds more cleanly at higher volumes. Most modern thermal printers accept both.
