4 × 6 in Thermal labels for Shopify

LabelCraft - barcode labels for Shopify that print at exactly the size you set.

The guarantees behind every label
Exact to ±0.1 mm

Every label prints at the size you set - measured, not approximate.

Never a silent failure

Overflow or a missing barcode always raises a visible warning before you print.

Whole-dot barcodes

Every bar lands on whole printer dots, so codes stay crisp and scan first time.

Your barcodes, untouched

We never overwrite or reassign a product's existing barcode.

The 4 × 6 in thermal label is the shipping size - and in a stockroom it doubles as a carton and pallet label with barcode room to spare. Exact size and scan verdicts below.

Exact size, in mm and inches

Each label measures 101.6 × 152.4 mm (4.00 × 6.00 in). LabelCraft's built-in preset uses those exact dimensions - the engine renders at the label's true size, so what you approve on screen is what lands on the roll.

Will a barcode scan at this size?

These verdicts come from the same pre-flight engine the app runs before every print: a barcode's narrow bars must land on whole printer dots (at least 2 dots per module), so the floor is exact, not a rule of thumb. Longer explanation in minimum barcode size and why a barcode won't scan.

What prints it

This is a generic thermal size, not any one brand's: the same rolls are sold for Zebra (ZD410 (203 dpi), ZD420 (203 dpi), ZD420-300 (300 dpi), GK420d (203 dpi), GX420d (203 dpi), ZD620 (203 dpi)), Rollo (Rollo X1040, Rollo Wireless X1038), Munbyn (Munbyn ITPP941), Phomemo (Phomemo PM-241) and most other desktop thermals. The full model list with native DPIs is in the printer compatibility guide.

Printing this format from Shopify

In LabelCraft, pick Zebra 4 × 6 in (shipping) in the template picker: the barcode box, the text autofit and the pre-flight checks above are already sized for this exact label. The free plan prints 200 labels a month - enough to validate the format on your own printer before it costs anything.
