ZPL Label Sizes Guide: 4x6, 4x4 & 100x150

23-09-2026 · Quick Cropper

ZPL labels come in a handful of standard sizes. Knowing which one you have helps you print them correctly with the ZPL to PDF converter.

Common Label Sizes

  • 4 × 6 in (101.6 × 152.4 mm) :

    The standard shipping label used by Amazon and most couriers.

  • 100 × 150 mm :

    The metric version of the shipping label, almost the same size.

  • 4 × 4 in and 4 × 3 in :

    Smaller shipping and product labels.

  • 2 × 1 in and 3 × 2 in :

    Barcode and product stickers.

Print Density Matters Too

The same ZPL looks different at 152, 203, 300 or 600 dpi. Shipping labels are usually written for 203 dpi printers.

Not Sure? Let the Tool Detect It

The converter reads the size from the ZPL commands when they are present, or estimates it from the label content, and you can change it any time.

Conclusion

Most shipping ZPL is 4 × 6 inches at 203 dpi. For anything else, pick the size from the list or enter a custom size in the ZPL to PDF converter.
