Dymo 30334 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 2¼ × 1¼ in Dymo 30334 is the workhorse product label of the LabelWriter world: big enough for a retail barcode, small enough to fit anything in the store. Here is its exact size, what scans on it, and how to print it from Shopify.

Exact size, in mm and inches

Each label measures 57.2 × 31.8 mm (2.25 × 1.25 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?

EAN-13 / UPC-A: scan comfortably. The preset's barcode box is 54.2 mm wide against a 28.3 mm minimum at 203 dpi - 25.9 mm of headroom.
Code 128 (SKU barcodes): a worst-case value up to 14 characters stays scannable in this box - that is tight, so shorter SKUs scan with more margin.

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

A Dymo roll size: it runs on the LabelWriter family - LabelWriter 450, LabelWriter 550, LabelWriter 4XL, LabelWriter 5XL, LabelWriter Wireless, all 300 dpi native. LabelCraft checks the template's DPI against your printer and warns before a roll is wasted when the bars would land off the dot grid - the rule is explained in 203 vs 300 DPI.

Printing this format from Shopify

In LabelCraft, pick Dymo 30334 (2¼ × 1¼ in) 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.
