Solving Shipping Label Printing Problems

4 × 6 inches (101.6 × 152.4 mm) is a widely supported thermal shipping-label format used by major carriers and e-commerce workflows.While USPS, UPS, FedEx, and DHL commonly support this format, carriers may also accept alternative sizes such as 4 × 4 inches or standard sheet layouts. Problems arise when the printer driver settings don't match the loaded label stock.

Why Labels Print at the Wrong Size

The most common issue is "Fit to Page" scaling. When your printer driver is set to Letter or A4 paper but you're sending a 4 × 6 layout, the driver may shrink the label to fit the larger sheet. To fix this:

  • Set print scaling to 100% (Actual Size).
  • Set the paper size in the driver to match the physical paper loaded.
  • Disable "Fit to Page," "Shrink to Printable Area," and similar options.

Printing 4 × 6 Labels on A4 or Letter Paper

If you don't have 4 × 6 label stock, you can print on standard A4 or Letter paper and cut the label to size. Set the paper size in the driver to A4 or Letter (not 4 × 6) and print at 100% scale. The label will appear at its actual size in one area of the sheet.

Shipping Label FAQ

What size is a standard shipping label?
4 × 6 inches (101.6 × 152.4 mm) is a widely supported thermal shipping-label format used by major carriers and e-commerce workflows. Some carriers also accept 4 × 4 inch labels or full-sheet formats for specific services.
Is my shipping label 4 × 6?
A 4 × 6 label measures 101.6 × 152.4 mm or exactly 4 × 6 inches. If your label stock has different dimensions, it is not a standard 4 × 6. Use the checker above to verify the fit.
Why is my shipping label printing too small?
The most common cause is the "Fit to Page" or "Shrink to Fit" option in your printer settings. This scales the 4 × 6 label down to fit a larger sheet like A4 or Letter. Set scaling to 100% (Actual Size) and select the correct paper size in your printer driver.
Why is my shipping label being cropped?
Cropping happens when the label dimensions are larger than the paper loaded in the printer, or when the printer cannot print borderless. Check that the paper size in the driver matches the physical paper, and that the label fits within the printable area.
Can I print a shipping label on A4 paper?
Yes. A 4 × 6 label fits on A4 paper, but you should set scaling to 100% and print at actual size. The label will print in one area of the sheet, and you can cut it to size. Alternatively, use adhesive label stock in 4 × 6 format for direct printing.
Can I print a 4 × 6 label on Letter paper?
Yes. Letter paper (8.5 × 11 in) is larger than a 4 × 6 label. Print at 100% scale without "Fit to Page." The label will appear at its actual size, and you can trim the excess paper.
