How we calculate this
Methodology and source handling
We convert physical sizes to inches, multiply by the selected DPI/PPI value, and round to whole pixels.
Quick answer
Copy-ready answer
A US passport photo is 2 x 2 in, about 51 x 51 mm. At 300 PPI that is 600 x 600 px, but official digital submissions also have separate pixel and composition rules.

Formula
How to calculate this size
50.8 mm x 300 PPI = 600 px wide.
Use this when the artwork stops at the finished edge.
Add 0 mm per side before calculating pixels when artwork reaches the edge.
Common mistakes
Avoid these photo sizing mistakes
A file can be the right pixel size and still fail official head-size, background, lighting, expression, or recency rules.
Passport authorities usually specify head placement and face size separately from the image canvas.
Passport photo rules can change and vary by authority, so verify the official source before submission.
