2x2 picture size in cm, mm and pixels
A 2x2 picture is 2 inches on each side: 5.08 × 5.08 cm, usually rounded to 51 × 51 mm, as the US State Department writes it. It is square, unlike the upright 35 × 45 mm photo many countries call passport size.
In pixels, 2 inches at 300 dpi is 600 × 600, the size this page saves. The US visa photo rules accept a square digital image from 600 × 600 up to 1200 × 1200 pixels.
