Face size in passport photos
Why face size matters, how it is estimated in-browser, and how to think about preferred head-height ranges in document photos.
Aim for the center of the allowed head-height range, not the edge, and keep enough top space so the crop feels stable.
Head size is one of the most important measurable signals in a document photo because it directly affects recognizability and consistency.
How it works
Measure head height
The checker estimates how much of the frame the head occupies.
Compare against range
Each requirement profile defines a minimum, maximum, and preferred head-height percentage.
Adjust the crop carefully
Increase or decrease zoom before making riskier edits.
Review top space too
Correct head size still fails if the head is too close to the top edge.
Common issues
Head too small
Head too large
Good head size but poor top margin
Face shifted off-center
Need a clean background first?
Use a separate background-removal tool first, then come back here to match the crop, size, and final export.
Background cleanup opens on a third-party site. Clean the background there first, then come back here to crop and export.

Use auto crop and then fine-tune alignment while watching the face-size metrics update live.

How precise is browser-based head-size detection?
It is useful but not perfect. The tool uses browser-available detection and cautious heuristics, then labels uncertainty clearly.
Can I trust a pass on head size alone?
No. Head size is only one part of the overall document-photo review.
