FAQ
What are the dimensions of A4 (or any paper size)?
210 × 297 mm, or 2480 × 3508 pixels at 300 DPI. Search any size on this page and its dimensions in both mm and print pixels appear instantly, offline — the full A-series plus US Letter, Legal and Tabloid.
What pixel size should I design at for print?
Multiply the mm size by the DPI: A4 at 300 DPI is 2480 × 3508 px. The table gives the 300-DPI pixel dimensions directly, so you can set up an artboard without doing the maths.
Is anything uploaded?
No — the table is bundled and searched on your device; it works offline.
What is the ratio of A-series paper?
Every A-series sheet has a 1:√2 ratio, so folding it in half gives the next size down (A4 → A5).
Limits
Covers ISO 216 A-series and common US sizes at 300 DPI. Other resolutions scale linearly.
