Why 4x6 is the standard
Most Indian sellers now work with thermal roll printers that use 4x6-inch sticker labels. This size is compact, readable, and much easier to print in bulk than full A4 shipping sheets.
It also helps you reduce paper waste, avoid cutting labels manually, and keep each parcel ready for courier pickup without extra formatting work.
What happens when the size is wrong
If the shipping label is too large, part of the barcode or address may be lost after the crop. If the print is too small, the courier scanner may struggle to read it.
This is why the label format should be standardized before sending to the thermal printer.
How to prepare the right format
- Download the order label PDF from the marketplace.
- Remove invoice content and extra sheet margins.
- Keep only the shipping label area.
- Resize to the standard 4x6 thermal label size.
- Print in one merged PDF batch.
Ideal use case for CropLabels
CropLabels helps with this automatically. It detects label boundaries, trims invoice pages or invoice sections, and outputs the final label in the correct thermal roll format.
This makes it especially useful for sellers who handle orders from multiple marketplaces in the same daily batch.
