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 1,224 × 1,584 Screen and web only
96 DPI 1,632 × 2,112 Windows screen default
150 DPI 2,550 × 3,300 Draft and home printing
300 DPI 5,100 × 6,600 Standard for commercial print and print-on-demand
600 DPI 10,200 × 13,200 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.
