How to convert passport photo measurements
- Inches to millimeters: multiply by 25.4 (2 in × 25.4 = 51 mm).
- Millimeters to pixels at 300 DPI: multiply by 11.81 (45 mm × 11.81 ≈ 531 px).
- Inches to pixels at 300 DPI: multiply by 300 (2 in × 300 = 600 px).
Head size is part of the measurement
The outer dimensions are only half of it — your head must also be the right size within the frame. For the US, the head (chin to crown) must be 1 to 1⅜ inches (25–35 mm). For 35×45 mm countries it is usually 32–36 mm. A photo that is the correct outer size but has the head too small or too large is still rejected.
