A4, A3, A2 and A5 Print Sizes in Pixels
ISO A sizes are the paper standard outside North America: A4 is the office sheet, A3 the poster, A2 and A1 the large formats, A5 the card. All share one shape (1:√2), so one file covers them all. A4 at 300 DPI is 2,480 × 3,508 pixels.

Pixels = inches × DPI, rounded to the nearest whole pixel. 300 DPI is the print-shop standard for prints seen up close; 200 is fine on a wall; 150 is the floor. Etsy itself sets no DPI rule.
What sellers use this ratio for
- Printables for buyers in Europe, the UK, Turkey and Australia who print at home on A4.
- Planners, worksheets and checklists sold as A4 and A5 PDFs.
- Posters sold as A3 and A2 for print shops that stock ISO paper.

Print Size & DPI CalculatorFrequently asked questions
What is A4 in pixels?
At 300 DPI, 2,480 × 3,508 pixels (210 × 297 mm). At 200 DPI it is 1,654 × 2,339 and at 150 DPI 1,240 × 1,754.
Does one file cover A5, A4, A3, A2 and A1?
Yes. Every A size has the same 1:√2 shape, so a single file prints at all of them without cropping. An A1 master at 300 DPI is 7,016 × 9,933 pixels and covers the rest at higher DPI.
Will a US letter or 8×10 file fit A4?
Not exactly. US letter (8.5×11) is slightly wider and shorter than A4, and 8×10 is squarer still. Both print on A4 with a small margin or crop; a dedicated A file avoids it.
Need 300 DPI files for every ratio?
Wall Art Studio upscales one artwork and exports print-ready files in 2:3, 3:4, 4:5, 11×14, square and A sizes, ready to upload to Etsy.
