Sizes are not the hard part
Requirements vary by country, and the common ones are easy to look up:
- United States: 2 × 2 inches (51 × 51 mm), head between 25 and 35 mm from chin to crown.
- United Kingdom, Schengen countries, Australia: 35 × 45 mm, head between 29 and 34 mm.
- Canada: 50 × 70 mm, head between 31 and 36 mm.
- India: 51 × 51 mm for passports, with other sizes for other documents.
- China: 33 × 48 mm.
Getting the dimensions right is arithmetic, and the passport photo maker handles it for more than twenty countries, including the head-height proportion that goes with each size. The rejections happen elsewhere.
The head proportion, which people get wrong constantly
Every specification governs not just the photo's size but how much of it your head occupies. A picture cropped from a holiday snapshot usually fails because the head is too small; a selfie held at arm's length often fails because it is too large, or because the nearest features are distorted by proximity.
The rule of thumb that works: the head should fill roughly 70 to 80 percent of the frame's height, with a small margin above the hair. Photograph from about two metres away and crop in, rather than holding the camera close.
Background
Most countries require a plain, light, uniform background — white or off-white for the US and UK, light grey accepted in several others. What fails is not usually colour but unevenness: a shadow cast on the wall behind you, a visible corner where two walls meet, a doorframe, or texture in the paint.
Stand about a metre away from the wall rather than against it. That single change removes most shadow problems, because the shadow falls behind you and out of frame.
Lighting and expression
Even, diffuse light is the goal. Face a window on an overcast day and you have close to ideal conditions. Direct sun creates hard shadows under the brow and nose; a camera flash creates red-eye and a bright hotspot on the forehead.
Expression must be neutral, with the mouth closed and both eyes open and clearly visible. A slight smile is grounds for rejection in most countries — a rule that catches people out precisely because smiling for a camera is instinctive.
The details that quietly fail applications
- Glasses. The UK and several other countries now require them removed entirely. Where they are permitted, frames must not obscure the eyes and there must be no glare on the lenses. Removing them is simply safer.
- Hair across the face. The full face from chin to hairline must be visible. Hair over an eyebrow can be enough.
- Head coverings. Permitted for religious or medical reasons, but the full face from chin to forehead must remain visible, and no shadow may fall across it.
- Uniform. Rejected in many countries. Ordinary clothing that contrasts with the background is what you want — avoid white shirts against white walls.
- Age of the photo. Usually must be taken within the last six months.
- Digital editing. Removing a blemish is generally tolerated; altering facial features, skin tone or eye colour is not, and increasingly gets detected.
Photographs of babies and small children
The rules relax somewhat — a neutral expression is not required for infants, and eyes may be closed for newborns in some countries — but the background rule does not. The usual approach is to lay the child on a plain white sheet and photograph from directly above, which gives an even background and no shadow.
Nobody else may appear in the frame, including a supporting hand, which is the most common reason a baby's photo comes back rejected.
Digital submissions have separate rules. Online applications typically specify a minimum pixel size and a maximum file size, and the two pull against each other. If your photo is above the file limit, reduce it with the image compressor rather than shrinking the dimensions, which would take you below the resolution requirement.
A workflow that generally passes
- Stand a metre from a plain, evenly lit wall, facing a window.
- Have someone photograph you from about two metres away, at eye level.
- Neutral expression, mouth closed, no glasses, hair clear of the face.
- Crop to your country's size and head proportion.
- Check the file size against the application's limit before uploading.
Getting it right the first time is worth the ten minutes. A rejected photo does not just cost a reprint — it restarts a queue.
Frequently asked questions
Can I smile in a passport photo?
No. Most countries require a neutral expression with the mouth closed. A visible smile is one of the more common reasons for rejection.
Can I wear glasses in a passport photo?
The UK and several other countries require them removed. Where they are allowed, frames must not obscure the eyes and there must be no glare. Removing them avoids the risk.
What background does a passport photo need?
A plain, light, uniform background, usually white or off-white. Standing about a metre from the wall prevents the shadows that cause most background rejections.
