Print Mercari Shipping Labels: 4 × 6 Settings & PDF Help
Start with Mercari’s label size setting. A thermal-ready download is simpler than repairing a Letter-size page after the fact.
For a thermal printer, choose 4 × 6 in Mercari. For an office printer, use 8.5 × 11. PaperReady can prepare an existing PDF; it does not buy postage or create a Mercari shipment.
Step-by-step instructions
- Open the sold item’s Order Status page in Mercari, then find Shipping Information → Label.
- Choose Set paper size, select 4 × 6 for thermal stock or 8.5 × 11 for an office printer, and save.
- Download the label and inspect the preview. Set your printer to the matching paper, then print a thermal label at Actual size / 100%.
- To find the label again in the app, go to Profile → Selling → In Progress, select the item and choose View Label.
When to crop a label PDF
If your preview shows a small label surrounded by an entire Letter page, changing the printer's paper size alone will shrink that whole page. First isolate the label. If the PDF page is already 4 × 6 inches, skip cropping.
- Open Print a label file and select the PDF. File preparation happens in your browser; downloading the result needs no account.
- Select the correct page, rotate if necessary, and drag a crop around the complete label. Include all barcodes and their surrounding white space.
- Choose 4 × 6 inches only for a label intended for that stock. Check that the preview is upright and the proportions look right.
- Choose Download PDF, select matching paper in your PDF viewer and printer driver, and print at Actual size / 100%.
Never recreate a shipment barcode as typed text or stretch the artwork to fill the page. If a barcode is already blurred, download the original label again.
Fix the symptom you see
| Symptom | Likely cause | Try this |
|---|---|---|
| Tiny label in a corner | A Letter-size PDF is being fit onto a label | Crop the label region, then export to the intended label size. |
| Correct shape, wrong size | Viewer or driver scaling | Set both the PDF print dialog and driver to the same stock. Use Actual size and measure a calibration PDF. |
| Sideways or clipped | Orientation or crop mismatch | Rotate in the preview; make sure the complete label fits before exporting. |
| White lines or blank output | Printer, media or head issue | Try the manufacturer’s own test page. If that also fails, check media loading and cleaning instructions. |

Eligible USPS and UPS prepaid labels offer a QR code that a staffed USPS Post Office or The UPS Store can scan to print your label. Check the QR instructions on your order; an unattended drop box cannot print it.
