2 × 2 inch is 50.8 × 50.8 mm, or 600 × 600 px at 300 dpi.
Crop and resize a photo to 2 × 2 inch below. 6 documents in this library use this print size; each still has its own background, file and head-size rules.
A phone photo is fine. Face the camera, use even light and keep your full head and shoulders in frame.
Reading the background…
Some items still do not meet this rule after the automatic checks. AI can rebuild the background and gently correct pose while preserving your identity.
AI generation starts only when you press the button. The browser-optimized photo is then uploaded for processing — compare the generated face with the original before use. Privacy policy
Print at Actual Size / 100%. Turn off “Fit to page” and borderless fill — both rescale the photo silently, and the millimetres come out wrong.
2 × 2 inch is only the size. Background, file limits and head height are set per document — open yours to check the rest.
Unit conversion only. None of these numbers is an extra requirement.
The difference is rounding: 2 × 2 inch is exactly 50.8 mm. This is one physical size, but the authorities do not all write it the same way, so both forms appear exactly as published. Use the number your own authority publishes — the page for each document shows its own.
Each links to its own page with that authority's full published rule and its official source. The print size is shared; nothing else is.
