A1 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.

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.

Rounding the canvas
At 300 PPI the exact width is 7,015.748 pixels and the height 9,933.071 pixels, so a whole-pixel canvas must round. Nearest rounding gives 7016 × 9933; rounding up gives 7016 × 9934, which keeps both axes at or above 300 PPI.
The aspect ratio is 1 : 1.4158, 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 A1 in pixels at 300 DPI?
7016 × 9933 pixels portrait, or 9933 × 7016 landscape, about 69.7 megapixels.
What is A1 in pixels at 72 or 96 DPI?
At 72 DPI: 1684 × 2384 px. At 96 DPI: 2245 × 3179 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.
