Shipping Label Size Guide & How to Make a Shipping Label

Choosing the right shipping label size helps you print clear labels and prepare packages correctly.

For many US online sellers, 4 × 6 inches is the standard shipping label size used for everyday parcel shipping. However, other sizes and formats are available. This guide explains common shipping label sizes, carrier requirements, how to choose the right label, and how to create and print shipping labels.

What Size is a Shipping Label?

Here are several common sizes and the situations in which they may be used.

4 × 6 inches — Standard shipping label size

4 × 6 inches is one of the most common answers. This size provides room for the shipping address, barcode, and tracking information. It is widely used by e-commerce platforms and major carriers. A thermal label printer 4x6 is a practical option if you regularly print this format.

2 × 3 inches — Smaller shipping labels

This smaller format may suit small parcels, jewelry boxes, and packages that need less label space. Before using it, check that the required address and barcode remain clear and readable.

2 × 4 inches — Smaller shipping labels

A 2 × 4-inch label may work for small parcels or certain return-label formats. Check your shipping platform's requirements before choosing it. Not every carrier or service supports every size.

4 × 5 inches — Alternative thermal label format

Some shipping systems support 4 × 5-inch labels. For example, this size for certain ZPL and EPL2 label outputs. Its availability depends on the carrier and label format.

4 × 7 inches and 4 × 8 inches — Alternative label formats

Some shipping systems support these sizes. Certain UPS labels generated in 4 × 7 or 4 × 8 formats may contain a 4 × 6 label with extra blank space. DHL Express also supports these sizes. Check the exact output format before printing.

8.5 × 11 inches — US letter-size sheet

This is the size of a standard US letter sheet, not necessarily the size of the shipping label itself. It is useful when printing through an inkjet or laser printer. The sheet may contain one label, multiple labels, or a smaller label positioned on the page. 

The Common Shipping Label Requirements by Carriers

The right shipping label size depends on your carrier and shipping service. UPS, USPS, and FedEx commonly support 4 × 6-inch labels, but their other formats and printing options can differ. Check the instructions provided by your carrier or shipping platform before printing.

UPS Shipping Label

A 4 × 6-inch shipping label is a common format for UPS shipments. It supports thermal printers that print 4 × 6-inch labels. UPS WorldShip also supports 4 × 8-inch labels and several letter-size laser label layouts.

If you use a thermal printer, make sure it supports the label size selected in your UPS shipping software. If you use an inkjet or laser printer, select the correct page layout. Check the print preview to make sure the address and barcode are complete.

USPS Shipping Label

A 4 × 6-inch shipping label is a common format for USPS shipments. USPS Click-N-Ship states that online shipping labels should print at approximately 4 × 6 inches.

You can print labels on self-adhesive label paper or plain white paper. Make sure the label is large enough to read. Do not cover the barcode or the postal-use area with tape.

Always check the print preview and confirm that the address and barcode are clear before attaching the label.

FedEx Shipping Label

A 4 × 6-inch label is a common format for FedEx shipments. FedEx's bulk label service offers 4 × 6-inch labels and 4 × 6.75-inch labels with a detachable document tab.

The available label format depends on your shipping service and printing setup. Follow the format provided by your FedEx shipping system and make sure your printer supports it.

Before attaching the label, check that the address and barcode are complete and readable.

DHL Shipping Label

DHL Express generates shipping labels through its online shipping platform. The required format depends on the label and document files provided for your shipment.

After creating your shipment, print the label using the instructions provided by DHL. Make sure the label prints at the intended size and that all required information is visible.

For international shipments, check whether your shipment also requires customs forms or other supporting documents. Keep the shipping label and any required documents ready for pickup or drop-off.

How to Choose the Right Shipping Label Size

Choosing the right shipping label size comes down to four main factors: carrier requirements, package size, printing volume, and printer compatibility.

Check the Carrier Requirements

Start by checking the format provided by UPS, USPS, FedEx, or your shipping platform. A size that works for one shipping workflow may not be available for another.

If you use an online marketplace, check its label instructions before buying labels in bulk.

Consider the Package Size

Choose a label that fits the available space without covering folds or edges. A 4 × 6-inch label works for many boxes and poly mailers, but it may look too large on a small envelope.

Do not choose a smaller format unless it is supported and keeps all required information readable.

Think About Your Printing Volume

Your daily shipping volume can affect which label format and supply type work best.

If you print many labels each day, fan-fold labels may be convenient because they are stacked flat. Roll labels can be a practical choice for smaller operations and compact workspaces.

Check Printer Compatibility

Not every printer supports every label size. A thermal label printer usually works with specific label widths and formats. A standard inkjet or laser printer uses compatible sheets or paper.

Before buying labels, confirm that your printer supports the size and format you plan to use. This can help prevent incorrect scaling and misaligned prints.
