Shoot for the checks that come afterwards

A photo booth earns its fee by knowing the rules, not by taking better pictures. All it takes is a phone, a bare wall, daylight from a window and about ten minutes, and the result can meet the rules of most countries. This guide is built around what happens next: once you drop the photo into the checker, it measures five things — the crop’s proportions, the pixel count, the head height, the background and the file — and most steps below set one of them up. Expression, glare and the photo’s age remain your job. To see right and wrong side by side, open the examples gallery.

1. The wall, for the background check

The checker samples the wall in the photo’s top corners and along its upper side edges, and flags one that is dark, tinted, patterned or unevenly lit. It does not read the wall right around your head. Every authority wants the same thing — plain, light and featureless — so choose, in this order:

1. a bare wall in smooth white or off-white;
2. a white bedsheet or a big piece of white paper fixed flat with tape, large enough to reach below your shoulders (smooth it first, because creases and texture show up);
3. a pale grey or cream wall, which suits the UK but is risky for the US, China and India, where white is required; the checker looks for white or off-white, so it may still warn on cream or light grey for a UK photo, and fail a grey that photographs darker.

Then step 0.5–1 m away from it rather than leaning on it. The gap stops your head casting a shadow on the wall, one of the most common reasons home photos fail. The checker can’t see a shadow directly behind your head, so look for one yourself.

2. The light, for the wall and for your face

Face a window and use daylight only, out of direct sun. Soft daylight from the front is ideal passport light: even, gentle and free of shadows, and an overcast midday is best of all. Three set-ups to avoid: ceiling lights, which leave the eye sockets dark; light from one side, which brightens one cheek and darkens the other (validators measure that as luminance variance); and a flash aimed straight at your face, which adds red-eye and a bright hotspot. Get light onto the wall as well as onto you, because an unevenly lit wall is one of the things the background check reports.

3. The camera, for the head-size check

• Shoot with the rear camera rather than the front one: its sensor is better, and a front lens at close range distorts your face.
• Keep the lens level with your eyes and roughly 1.5 m from your face. A phone held lower than your eyes is the framing mistake seen most often.
• Hand the phone to a helper, or stand it against something steady and set a 3-second timer; never shoot at arm’s length.
• Leave plenty of room around your head and shoulders. Cropping to the exact ratio comes later, and a frame that is too tight can’t be rescued.

Distance protects the head-size check rather than setting it: shoot too close and your head can fill more of the frame than the band allows, with no margin left to crop wider. The band itself is set when you crop (step 6).

4. The pose, which no check can measure

Turn your shoulders square to the lens and keep your head straight, with no tilt or turn. Eyes open and on the lens, mouth closed, expression neutral. Tuck your hair behind your ears so it stays clear of your eyes. Take your glasses off: the US bans them, the Chinese visa centre in Macau and India’s ICAO guideline both say to remove them, and everywhere else they risk glare. A religious head covering must leave your whole face visible, from chin to forehead and edge to edge, with no shadow across it. The checker can’t judge any of this, so get it right while you shoot.

5. A burst, not a single frame

Take ten shots, not two. Small faults — a blink starting, a slight tilt, a stray shadow — stand out when you compare frames and hide when you look at one alone. Choose at full zoom: sharp eyes, both lit the same, no shadow on the wall behind, a clean background.

6. The crop, for the proportion and head-size checks

Crop for the document you are applying for; the requirements tables list every preset. A US photo is a 2×2 in square, a Schengen photo 35×45 mm and a Chinese visa photo 33×48 mm — three different shapes. Place the crop so the crown-to-chin height falls inside the band (25–35 mm of 51 mm for the US, 32–36 mm of 45 mm for Schengen), with a little space above the crown and the shoulders still in the frame.

7. Run the checker, then check what it can’t

Drop the cropped file into the checker and pick the matching preset. It compares the proportions, pixel count, head height (two clicks on the preview) and file size with that document’s limits, checks the background the same way for every preset, and names any rule the photo misses. It can’t judge expression, glare or how recent the photo is, so finish with an honest look of your own: is it a true likeness of you as you look today, with even light and a clean wall behind? If so, print it on photo paper — matte or glossy, whichever your authority asks for — or upload the file as it is. Leave out filters and retouching entirely. Applying to the US? Make one last pass through the State Department requirements checklist — it covers the rules a file can’t reveal, like the six-month recency limit and the glasses ban.

Frequently asked questions

Can I take a passport photo with my phone?

You can. Any recent phone camera captures far more detail than the rules need; 600×600 px already covers the US requirement. Use the camera on the back rather than the selfie camera: its sensor is sharper, and the wider front lens held at arm's length distorts your proportions. Ask someone to take the shot, or stand the phone up and let the timer fire it.

Why shouldn't I use a selfie?

The front lens is a wide-angle made for arm's length. At that distance it makes the nose look bigger and the ears smaller, a small change in the geometry of your face that biometric matching can flag. Selfies are also usually taken from below, with the camera tilted up at you, which is a classic reason for refusal. The rear camera on a timer, propped up at eye level, avoids both problems.

What wall works as a background?

Choose the barest white or off-white wall in your home, with no texture, hooks or light switches inside the frame. A slightly grey wall is acceptable for the UK, which accepts cream or light grey, but is borderline where white is required: the US, China and India. If no wall qualifies, tape a smooth white sheet flat against one and iron it first, because every crease shows up as a line.

How far should the camera be from my face?

Roughly 1.5 metres (5 feet). Any closer and the lens exaggerates your nose and the head-size percentage gets hard to control; much further away and your head ends up too small in the frame. Keep 0.5–1 m between you and the wall so your shadow drops out of the shot, and include your head and shoulders with a margin above the top of your head; the crop to the right ratio happens afterwards.

What should I wear?

Ordinary clothes in a colour that stands out from the wall; a white top against a white wall blurs your outline. Leave out uniforms and camouflage (a US rule) and hats, and take your glasses off if you can. A religious head covering is fine where the rules permit it, as long as your face stays fully visible and free of shadow from chin to forehead.

The photo looks fine but the checker still flags it — why?

Nearly always the head size or the background tone, which are the two things people misjudge most by eye. A head percentage outside the band means cropping tighter or looser. A background flagged as dark or uneven means lighting the wall itself more brightly, not just your face, and shooting again. Each check's detail line tells you what it measured and which limit the photo missed.
