Editorial methodology
How we compile, verify, and update the Fast Passport Photo Online spec database.
Last reviewed: · First published
Why methodology matters
A passport or visa photo is a small object with strict tolerances: a few millimetres of head height, a few kilobytes over the file ceiling, or a tinted background can all cause rejection. The cost of getting it wrong is a new appointment, a re-print, and (for visas) a delayed application. Our job is to remove the spec-research step so you only worry about the capture.
Our six-step editorial process
- Primary source first. We do not aggregate competitor data. Every spec starts at the authority's published page (passport office, ministry of foreign affairs, or visa application centre).
- ICAO Doc 9303 alignment. Face geometry and head-coverage percentages reference Part 4 of ICAO Doc 9303 (Machine Readable Travel Documents) wherever the issuing authority adopts it.
- Independent re-derivation. An editor independently re-derives the dimensions and DPI from the published rules. Mismatches between the spec database and the source page block release until reconciled.
- Pixel envelope validation. We compute the minimum and maximum pixel ranges from the millimetre size + the authority's DPI floor. Files outside this envelope are rejected by our processing pipeline before download.
- Rejection-reason cross-check. We mirror the authority's published rejection reasons on every country page so applicants see the same checklist the reviewer will use.
- Quarterly review cadence. Country templates are reviewed at least once per quarter, and immediately when a reader reports a spec drift or we detect a published change.
References we rely on
The umbrella biometric standard is ICAO Doc 9303 (Machine Readable Travel Documents), which most national authorities adopt for the "biometric portrait" envelope (head coverage, eye line, lighting). Country-specific overrides — for example China's 33×48 mm visa size or India's 51×51 mm passport — come straight from the issuing authority and override the ICAO defaults.
The exact reference URLs we used for each country are linked on the corresponding country page under "Where we sourced these specifications."If you ever find a mismatch between an authority's current page and our template, please report it via contact support — we revise within one business day for any spec correction.
What we automate vs. what you control
Our tool automatically handles cropping, head-coverage, background recolour, DPI/pixel resizing, file-size compression, and print-sheet layout. You control the capture: lighting, expression, glasses-off, posture, and consent for any minor in the photo. Both halves matter — see our country-specific rejection reasons blocks for what to watch for on your end.
Corrections & transparency
We publish a last-reviewed dateon every country and document page, plus a methodology version on this page. If a reader reports a spec correction we publish the change with the new review date — we don't silently amend.
