The 3×4 cm document photo
In countries like Brazil, Vietnam, Indonesia, and across Eastern Europe, 3×4 cm is a default photo size for national ID cards, student records, exam registrations, and job applications. It is compact enough to fit several to a printed sheet.
Converting 3×4 cm at 300 DPI gives 354×472 pixels, since 3 cm is about 1.181 inches and 4 cm about 1.575 inches. The image is resized on your device, so an ID photo for an official form stays private.
Preparing an acceptable ID photo
Most systems want a plain white or light background, a centered front-facing head, and a neutral expression. Because 3×4 cm is a portrait rectangle, leave a little headroom above the hair and keep the shoulders in frame.
If you need several prints, a 3×4 cm photo tiles neatly onto a 10×15 cm sheet, letting you cut out multiple copies. Confirm your institution's exact head-size rule, as some specify it in millimeters.
