Frequently Asked Questions About InPost Shipping Labels
What size label does InPost require for home and locker shipping?
The official standard size used across InPost’s shipping platforms and APIs is the universal A6 format (approximately 100x150mm). For standard Zebra or Brother direct thermal printers, select our 102 x 150 mm rolls. If you are using a wide-format Dymo printer, the correct match is the 104 x 159 mm (S0904980) model. Both sizes display all necessary address and routing data perfectly.
Can I print InPost parcel labels on a standard office printer using A4 sheets?
Yes, this is an excellent option for managing occasional shipments or starting your online store without investing in a dedicated label printer. You can download your InPost labels as PDFs from your Parcel Manager and print them using a traditional laser printer. To avoid wasting paper and time spent cutting sheets with scissors, we recommend our specialized A4 sheet templates. For standard compact layouts, our A4 sheet labels in 210 x 99 mm (3 stickers per page) provide a clean, professional solution that eliminates the need to use loose sheets or clear packing tape.
Why is the courier or InPost Locker scanner unable to read my barcode?
If an InPost locker screen or a courier's handheld scanner fails to flash your label, it is usually caused by fine, vertical white lines running through the printed bars. This occurs when paper dust or burnt adhesive residue builds up on your printer's thermal head, blocking the heat. Because automated sorting sensors require exact spatial intervals to route packages correctly, clean your printhead regularly with an alcohol wipe. Additionally, ensure the label is applied completely flat on a center surface and never wrapped over a fold or edge.
