Why Shopify Barcode Labels Get Cut Off — and How LabelCraft Stops It

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

EN · FR · DE · ES

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

Modules snap to your printer's dots, so codes stay crisp and scan first time.

Your barcodes, untouched

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

The worst label problem is the one you do not find until the till: a barcode that printed a little too big for its template, so a bar got clipped, the price ran off the edge, or the whole code shrank below the size a scanner can read. The labels look roughly right on the roll, and you only learn they are wrong when one will not scan in front of a customer. This guide explains what causes that overflow, why most label tools let it happen silently, and how LabelCraft is built so it can never reach the printer unseen.

What “overflow” actually means on a label

Overflow is simply content that needs more room than the label gives it. A 3-line product title, a long SKU, a price plus a compare-at price, and a barcode all have to fit inside a fixed physical area — say a 25 × 15 mm unit label. When the design asks for more space than exists, something has to give, and it shows up in one of three ways:

Bars clipped at the edge — the barcode runs past the label boundary and the last bars (or the quiet zone) are cut off, so the symbol is incomplete and will not decode.
Text truncated — a product title or SKU is chopped mid-word, or a digit of the human-readable number is lost, so the label is ambiguous or simply wrong.
The whole barcode shrunk too small — to make everything fit, the barcode is scaled below its minimum X-dimension, and a code that looks fine to the eye no longer scans.

Why the silent version costs you a sale — and a review

The damage is not the overflow itself — it is that it happens without telling you. Shopify's official Retail Barcode Labels app and most ad-hoc PDF templates will happily render an oversized design, clip whatever does not fit, and hand you a PDF that looks plausible. You print a roll of 200, shelve the stock, and discover the failure one customer at a time. “Labels won't scale / get cut off / won't scan” is the single most common theme in one-star reviews of barcode-label apps — not because overflow is rare, but because it is invisible until it is expensive.

LabelCraft's guarantee: never-silent overflow

LabelCraft is a precise rendering engine first. It draws every element at an exact physical size and treats “this does not fit” as a problem to surface, never to paper over. Three guarantees back that up, and they are enforced by the test suite, not just promised in marketing:

Exact dimensions (±0.1 mm). Every label, barcode, and element renders at the size you specified — no “fit to page” surprise, no driver rescaling. What you design is what prints.
Never-silent overflow. If any element would run past the label edge, or a barcode would print too small to scan at your printer's resolution, the print step raises a warning on screen — and nothing is quietly clipped behind your back.
Whole-dot barcode modules. Bars are aligned to the printer's dot grid for crisp, scannable edges, so a label that passes the size check also prints clean instead of fuzzy.

What you see before anything prints

On the print and location-label screens, LabelCraft runs a scan-readiness pre-flight against your actual codes and your chosen template — not a generic sample. A label that would overflow, or a barcode that would be too small to read, is flagged in a banner you have to see before the PDF is generated. The check looks at the real data going onto the roll, so the warning you get is about the exact labels you are about to print.

The problem-report CSV: every flagged label, in writing

When a batch has issues, LabelCraft does not just colour a banner red — it gives you a downloadable problem-report CSV listing each affected row and the reason: too small to scan, runs off the label, missing or invalid barcode, and so on. You can hand that file to whoever fixes the data or the template, work through it line by line, and re-run the batch knowing exactly what changed. Never-silent does not stop at the screen; it follows you into a file you can act on.

How to fix an overflow warning

Use a larger template, or move to a label stock with more room — a 3.5" or 4" template carries a long title and a full-size barcode comfortably where a small unit label cannot.
Remove or shorten elements you do not need on that size — a compare-at price or a long static line is often what tips a small label over.
Set the element's overflow mode to shrink to scale the text down automatically, or truncate to shorten it with an ellipsis on purpose — either way it is your choice, made on screen, never a silent guess.
Always print at 100% / actual size so the driver does not shrink the sheet — see the print-at-actual-size guide for the exact dialog settings.

If a label still will not read after it fits, the cause is usually elsewhere — walk through the barcode-not-scanning guide. To see how the never-silent approach compares with the official app, read LabelCraft vs Retail Barcode Labels, or start with the complete barcode-label guide.
