Australian sellers often group 100 x 150mm labels under the terms 4x6 shipping labels or A6 shipping labels. The sizes are close, but they are not mathematically identical: 4 x 6 inches is 101.6 x 152.4mm, while ISO A6 is 105 x 148mm. This product is the 100 x 150mm format stated on the listing. Check the page size selected in your printer driver or shipping platform before ordering.

| Pack option | Labels per roll | Total labels | Best suited to |

Will These 4x6 Label Rolls Fit My Printer?
Use these labels with a direct thermal printer that accepts 100mm-wide roll media. Printer brand alone does not confirm fit. Check the printer's supported media width, maximum roll diameter, core or external-holder requirements, label sensor and driver settings.
For a verified option in the Boxy Packaging range, pair the rolls with our thermal shipping label printer. It supports media widths from 30 to 110mm and includes an external label-roll holder. Set the page size to 100 x 150mm and calibrate the printer before the first batch.
Roll Labels or Fanfold Labels?
Roll labels keep the media contained and can suit compact packing stations with a compatible holder. Fanfold labels feed from a stack behind the printer and can make the remaining quantity easier to see. If a stacked format better suits your bench, compare these rolls with our 100 x 150mm fanfold thermal labels.

Common Shipping and Dispatch Uses
The 100 x 150mm format is commonly selected for ecommerce address labels, courier consignment labels, returns labels and warehouse dispatch. It provides room for recipient details, routing information and barcodes when the source file is designed for this page size.
Carrier and platform templates vary. Confirm that your shipping software outputs a 100 x 150mm layout, print one test label at actual size and check that every barcode and address field remains inside the label edges. Avoid using "fit to page" if it changes the intended scale.
How to Get a Clean First Print
- Load the roll with the printable thermal side facing the print head.
- Select 100 x 150mm in the printer driver and shipping platform.
- Run the printer's media calibration so it detects each label gap.
- Print one test label at actual size before starting a batch.
- Apply labels to a clean, dry and reasonably flat surface.

Frequently Asked Questions
Are 100 x 150mm labels exactly 4 x 6 inches?
No. Exact 4 x 6 inches is 101.6 x 152.4mm. The term 4x6 is often used as a shipping-label category, but this product's stated dimensions are 100 x 150mm.
Are these labels exact ISO A6 size?
No. ISO A6 is 105 x 148mm. Sellers sometimes use A6 as a shorthand for the wider shipping-label family, so always use the exact 100 x 150mm dimensions when checking your printer and template.
How many labels are in each pack?
Each roll contains 350 labels. The 3-roll option contains 1,050 labels in total, and the 24-roll carton contains 8,400.
Do these thermal labels need ink or ribbon?
No. They are direct thermal labels and print with heat from a compatible direct thermal printer.
Will they work with every courier platform?
They can be used when the platform or downloaded label file supports a 100 x 150mm page size. Check the carrier template and run a test print because layouts differ between services.
What surfaces can I apply them to?
The permanent adhesive is intended for common shipping packaging such as clean cardboard cartons and satchels. Dust, moisture, coatings and heavily textured surfaces can affect adhesion, so test unusual packaging first.
How should I store unopened rolls?
Keep thermal rolls in a cool, dry place away from direct sunlight, excessive heat and moisture. This helps protect the thermal coating and adhesive before use.
