Pixel dimensions by resolution

Pixels are not a property of the paper — they depend on the resolution you print at. Build the document at the size you will actually output.

ResolutionPixels (W × H)Use for
72 DPI 1,417 × 2,004 Screen and web only
96 DPI 1,890 × 2,672 Windows screen default
150 DPI 2,953 × 4,175 Draft and home printing
300 DPI 5,906 × 8,350 Standard for commercial print and print-on-demand
600 DPI 11,811 × 16,701 Fine art and high-detail line work

300 DPI is the number you want in almost every case. Print-on-demand services, Etsy printables and commercial printers all expect it. Exporting at 72 DPI and enlarging does not add detail — it just prints the same pixels bigger and softer.

Posters.

Why does B2 have that unusual aspect ratio?

Every ISO size has a 1:√2 ratio (about 1:1.414). Halving the long side gives the next size down with the same proportions, so artwork scales between sizes without leaving a margin or needing to be cropped.
