Standard International Paper Sizes Explained (A1 to A5 for Print)

While North American buyers use inch-based frames (like 8x10" or 16x20"), buyers in Europe, Australia, and Asia use metric A-series frames. If you don't include an ISO file, you lose international sales.

A-series paper sizes scale proportionally. This means a single high-resolution file formatted to the ISO aspect ratio can print at A1, A2, A3, A4, and A5 sizes without distorting the composition.

By including an ISO file in your digital downloads bundle, you open your Etsy printable shop to a global market, maximizing conversions.

To ensure your international files look crisp when printed, export your master ISO file at A1 dimensions. The buyer can scale it down to smaller A-series sizes:

To check how ISO sizes compare to standard US aspect ratios, refer to our Etsy printable size guide.

  Ignoring international buyers. Failing to provide an ISO file means European and Australian buyers have to stretch standard US aspect ratio files to fit local frames, ruining print quality.
• 2.
  Low-resolution exports. Creating files at A4 size pixels instead of A1. Always export your master file at the largest scale so it can be sized down cleanly. Refer to what 300 DPI resolution means for printables.
• 3.
  Manual resizing math. Sizing crops manually is slow. Learn about bulk options in how to bulk resize images for Etsy printables.
