Barcode Label Generator for A4 Sheets

What is A4 Barcode Label Sheets?

A label sheet is a page of self-adhesive labels laid out in a grid. To print on it, every barcode must land exactly inside its label, which is why the layout is defined in millimetres: page size, label width and height, horizontal and vertical gap, and top and left margin. The presets cover the common A4 divisions from 4 up to 40 labels per page, and the custom mode lets you type the measurements printed on your sheet's packaging.

The output is a real vector PDF, not a screenshot. Bars stay perfectly sharp, text remains selectable, and the page is sized to print at 100 % scale. The start position setting lets you begin on the first free label of a partly used sheet, so no labels are wasted.

Each label can carry the barcode with a product name, SKU, price or free text and an optional border. The data can be a simple pasted list or a CSV file, so a whole catalogue can be turned into labels in one pass.

When should you use it?

• You need product labels with barcode, name and price for a small shop or a market stall.
• You want inventory or asset stickers for boxes, shelves and equipment.
• You are printing shelf-edge tags for a store using EAN or Code 128.
• You have half a sheet of labels left and want to continue from the first free position.
• You need a barcode label PDF that a print shop can print at exactly 100 %.

Printing tips for barcode labels

Print at 100 % or Actual size. In the print dialog, turn off Fit to page and Scale to fit; any scaling shifts the labels out of their cells and changes the size of the bars.

Test on plain paper first. Print one page on ordinary paper, hold it against the label sheet in front of a light, and check that every barcode sits inside its label. If not, adjust the margins or gaps and print again.

Check the sheet's compatibility. Layouts differ between manufacturers even for the same number of labels per page, so compare the label size, gaps and margins on your sheet with the layout, or enter them in the custom mode. Feed the sheet in the orientation your printer expects.

Keep the quiet zones. Leave a blank margin of several millimetres on both sides of each barcode, and do not put text or borders touching the bars.

Mind the minimum bar width. For EAN-13, the nominal narrowest bar is about 0.33 mm and it should not drop below roughly 80 % of that. Very small labels with long values give thin bars that cheap printers blur; use a shorter value or a bigger label.

Then test-scan a printed label with the scanner you will actually use before printing the full run.
