Passport photo size in centimetres
Millimetre specs convert directly to centimetres by dividing by 10. The most searched cm sizes map to catalog documents: 5.1×5.1 cm (US square), 3.5×4.5 cm (European standard), 5×7 cm (Canada), 3×4 cm (Brazil/Spain), and 3.3×4.8 cm (China visa).

cm vs mm on forms
Government PDFs mix units. 35×45 mm and 3.5×4.5 cm are identical. Always verify whether the form means face crop or print paper (see 4×6 cm print page).
Convert cm to pixels
Use catalog DPI: cm → mm (×10) → inches (÷25.4) → pixels (×DPI). PicsForm stores the result so you do not manual-calculate.
