A0 pixel dimensions at each DPI
Calculated from the defining millimeter dimensions, rounded to the nearest whole pixel unless stated. “DPI” here means image pixels per inch (PPI), the way most print briefs use it.

|---|---|---|---|---|
| 72 DPI | 2384 × 3370 | 3370 × 2384 | 2384 × 3371 | 8 |

Nearest-pixel rounding can fall slightly below the target on one axis. Use Round up when the target is a strict minimum.
This is the canvas size. Changing a file’s PPI metadata alone does not create these pixels.

About A0
A0 is the base of the A series: 841 × 1189 mm, an area of about one square meter. It is used for large posters and technical drawings. At 300 PPI its canvas exceeds 100 megapixels, so check the density your printer actually asks for at that size.
| Unit | Width × height |
|---|---|
| Millimeters | 841 × 1,189 |
| Centimeters | 84.1 × 118.9 |
| Inches | 33.11 × 46.811 |
Rounding the canvas
At 300 PPI the exact width is 9,933.071 pixels and the height 14,043.307 pixels, so a whole-pixel canvas must round. Nearest rounding gives 9933 × 14043; rounding up gives 9934 × 14044, which keeps both axes at or above 300 PPI.
The aspect ratio is 1 : 1.4138, the √2 proportion shared by every A size, so A sizes scale into each other without cropping. Bleed is not included: add your provider’s bleed to each edge before calculating the file size.
Questions about this conversion
What is A0 in pixels at 300 DPI?
9933 × 14043 pixels portrait, or 14043 × 9933 landscape, about 139.5 megapixels.
What is A0 in pixels at 72 or 96 DPI?
At 72 DPI: 2384 × 3370 px. At 96 DPI: 3179 × 4494 px. These low densities suit on-screen previews and document templates rather than photo printing.
Does the page size include bleed or printer margins?
No. These are the nominal finished sheet dimensions. Bleed, safe areas and a printer’s unprintable margins are separate and depend on your provider and device.
