troubleshooting guide
Fix shipstation label prints too small or too large. Check scale, paper size, margins, orientation and barcode whitespace before reprinting.
Best next step
Start with the tool or template that matches this guide before printing paid postage again.

Start in ShipStation's Label Document Options, not with an arbitrary scale percentage. Choose the label layout that matches the physical printer—4 × 6 for a thermal workflow—then align the operating-system driver and print one test at 100% / Actual Size.
Symptom-led fix
Follow the symptom that best matches your bad print. Each step points to the safest next tool before you buy postage again.
A full Letter or A4 page is being fitted onto one 4×6 thermal label.
Inspect the PDF page box. Get the issuer's 4×6 format or extract only a complete label area; do not enlarge the miniature output.
Inspect the PDF pageA true 4×6 source prints proportionally smaller on matching 4×6 media.
Confirm 4×6 in the driver, disable Fit, print one blank template, then calculate a correction only if the media path already matches.
Measure the scale errorThe label boundary is correct, but fine lines are fuzzy, gray or broken.
Treat this as print quality, not page scale. Test density, speed, media and printhead condition before another live label.
Run a print-quality testShipStation's current help directs users to Settings > Printing > Printing Setup > Label Document Options. Choose the document format that matches the printer before troubleshooting browser or driver scale.
ShipStation identifies 4 × 6 as the option for thermal label printers. If the source layout is a larger sheet, do not shrink the entire page onto one thermal label; switch the document option and regenerate or reopen the label.
After ShipStation's layout is correct, set the printer driver to the same physical media and use 100% / Actual Size. Conflicting app and driver sizes can make output too small, too large, sideways or clipped.
Use a blank template or one non-production test to confirm size, alignment and barcode sharpness. Do not save a new default or print a batch until the page boundary fits one label without crop or automatic scaling.
This page is a practical print-setting checklist, not official carrier policy or a promise that a label will be accepted.
Confirm the current format in your platform or carrier account, keep the original PDF, and stop if a test print is cropped, blurred or incorrectly scaled.
Troubleshooting advice is general. Record the printer model, paper size, PDF viewer and scale setting so you can verify each change.
ShipStation documents them under Settings > Printing > Printing Setup > Label Document Options.
ShipStation currently identifies 4 × 6 as the thermal-label option.
Choose the correct ShipStation document option and driver media first. Use 100% / Actual Size after they match.
The operating-system driver, browser print dialog or saved printer preset may still use a different paper size.
Only after one test fits the physical label and the barcode is sharp, complete and unscaled.
