Label Formats and Sizes

ShipEngine provides labels in three formats:

Label FormatDescription
pdfAdobe PDF Format
pngA PNG (portable network graphics) image file
zplZebra Programming Language format, which is useful for printing with a Zebra Printer

By default, all labels are 4x6 (4 inches x 6 inches). You can optionally specify label_layout: "letter" to create labels in US Letter size (8.5 inches x 11 inches).

Example

The following example demonstrates setting the label_layout when creating a label.

Notice that the label_download object in the response includes links to download the label as pdf, png, and/or zpl. There is also an href field, which exists for backward compatibility purposes. We recommend that you use the other fields instead.
