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.
