Quick answer
A FedEx shipping label prints sideways when orientation, auto-rotate, media size or source layout is mismatched. Keep the label at Actual Size, match the paper, and turn off automatic rotation that sends a portrait label across the roll.

Printed from browser preview
The browser added margins or shrank the PDF to fit the sheet.
Download the label PDF and print from a PDF viewer at 100% before changing marketplace settings.

New printer or roll
Every label from this printer is slightly small.
Run a calibration sheet so you know whether the printer driver or the label file is causing the shrink.
Print calibration sheetPreflight checklist
- Identify whether the symptom is scale, paper size, offset or scan quality.
- Run a blank template before buying new postage.
- Reprint the original PDF after settings are corrected when the platform allows it.
Identify whether the source is sheet or 4×6
Open the FedEx label PDF and confirm the page size. A Letter page sent to a thermal roll can rotate or shrink unless the 4×6 label area is extracted correctly.
Control orientation explicitly
Choose portrait for standard 4×6 label output and disable auto-rotate if it turns the label sideways. If the preview changes orientation after choosing the printer, recheck media size.
Use Actual Size after matching paper
Once the printer media and PDF layout match, use 100% / Actual Size. Do not use Fit to Page to compensate for a sideways preview.
Print one test before drop-off
Confirm tracking barcode, service text and address blocks are upright, sharp and complete before attaching the FedEx label.
Source notes
This guide is based on recurring seller-support patterns: labels printed from browser previews, PDF viewers resizing files, thermal rolls loaded off-center, and barcodes losing quiet-zone whitespace.
When a platform or carrier offers a specific label-format setting, follow that official setting first, then use the checker and templates here to confirm print scale, paper size, orientation, and barcode quiet zone before shipping.
For troubleshooting, prioritize fixes that include printer model, paper size, PDF viewer, and scale setting before reprinting paid postage.
FAQ
Should I re-buy postage?
Usually no. First fix the print settings and reprint the original PDF if your platform allows it.
Why does Actual Size matter?
Barcode scanners expect the bars and quiet zone to remain within tolerance. Shrinking can make scans fail.
Can tape cause scanning problems?
Yes. Glossy tape over a barcode can reflect light and reduce scan reliability.
What should I try first if I am in a hurry?
Download the label PDF, print from a PDF viewer at 100% / Actual Size and make sure the selected paper size matches the paper in the printer.
How do I know whether the printer or the label file is the problem?
Print a blank template at 100%. If the template is also wrong, fix printer settings before changing the label file or buying new postage.
