4x6 Label

4x6 is the size platforms ask for when you print a shipping label. Pirate Ship's troubleshooting page says to choose 4x6 or 100 x 150 mm in the print dialog, and Etsy's help page is summarized as asking for 4 in x 6 in. If labels come out too big or too small, the paper size is the first thing to check.
