This is a unit conversion
It does not tell you what your document requires. Each authority sets its own size, and some publish a pixel size instead of a print size.
“5 × 5 cm” and “2 × 2 in”
These are the rounded forms people usually search for, and they are close — but they are not the same number. 5 cm is 50 mm. 2 in is 50.8 mm. PhotoSpec holds 51 × 51 mm for United States passport and visa photos. Use the size your authority publishes, not the rounded name.

About DPI
Authorities rarely publish a DPI. Where an authority publishes both a print size and a pixel size, the resolution implied in PhotoSpec's data ranges from about 70 to 900 dpi. If your application publishes a pixel size, use that figure — it is on the document's own page — rather than converting to one.
Questions
- How many pixels is a 35 × 45 mm photo?
- At 300 DPI it is 413 × 531 pixels. The arithmetic is 35 ÷ 25.4 × 300 for the width and 45 ÷ 25.4 × 300 for the height. Change the DPI above and the pixel figure changes with it.
- What size is a 5 × 5 cm visa photo in inches?
- 5 × 5 cm is 1.97 × 1.97 inches. People often write it as “2 × 2 in”, which is 50.8 mm — close, but not the same number. Check the size your authority publishes.
- What DPI should I use for a passport photo?
- Most authorities do not publish one. If yours publishes a pixel size, use that pixel size directly. If it publishes only a print size and your application asks for a DPI, use the DPI the application asks for.
