PDF Page Size Checker
Check whether your printable is US Letter, A4, or a custom size.
Getting your printable ready for buyers everywhere
The safest approach is to offer both US Letter and A4 versions in your listing. If you only make one, design at US Letter and tell buyers to choose “Fit to page” when printing on A4 — it scales cleanly with a small border. This tool confirms exactly which size your file is.
Frequently asked questions
Why does US Letter vs A4 matter for printables?
US buyers print on Letter (8.5 × 11 in); most of the rest of the world uses A4 (210 × 297 mm). If your printable is only one size, buyers on the other standard get cut-off edges or white borders. Many top sellers include both.
My PDF size could not be read — why?
Some PDFs store their page size in a compressed structure this in-browser checker cannot see. Try re-exporting or “printing to PDF” from your design tool, which usually writes a readable page size.
