Passport photo size in pixels, inches, mm and cm
A US passport photo is 2 x 2 inches, which is 51 x 51 mm, 5.1 x 5.1 cm, and 600 x 600 pixels at 300 DPI (up to 1200 x 1200 px). A UK/Schengen photo is 35 x 45 mm (about 413 x 531 px at 300 DPI), and a Canadian photo is 50 x 70 mm (about 591 x 827 px at 300 DPI). Pixel size depends on the DPI: pixels = inches x DPI.
How pixel size is calculated
Pixels = physical size (in inches) x resolution (DPI). At the standard 300 DPI, a 2 x 2 inch US photo is 600 x 600 pixels; at 600 DPI it is 1200 x 1200. To convert mm to inches, divide by 25.4.
This tool outputs the exact pixel size each country's online portal requires, so you don't have to resize anything yourself.
