Why passport photos get rejected

The faults that send a photo back

Seven things account for almost every returned photo: the head is the wrong size in the frame, there are shadows behind the head or under the chin, the background is not plain, the picture is soft, the expression is wrong, glasses throw glare, or the file shows signs of editing. The first three are geometry and light, settled before you press the shutter, and they are the ones people misjudge: a photo can look fine on a phone screen and still be four millimetres out.

No authority publishes a breakdown of why photos fail. GOV.UK, the US State Department and Immigration, Refugees and Citizenship Canada publish the rules, not the statistics. Read the order below as the order in which a fault is hard to spot in your own photo, not as a league table someone has counted.

1. Head size in the frame

What it means. Every authority that publishes a head measurement gives it as a chin-to-crown distance in millimetres inside a photo of a stated size. A photo can be sharp, well lit and nicely composed and still fail because the face fills more of the frame than the millimetre range allows.

How to tell. Crop to the finished shape, measure chin to crown as a fraction of the frame height, and convert that into real millimetres. On a UK photo the 29–34 mm range is roughly two thirds to three quarters of the height, but the published rule is the millimetres; the percentage is arithmetic on it. Judging it by eye is where people go wrong; the photo checker does it in millimetres.

The ranges do not all overlap: 29 mm satisfies the UK and misses France, Germany and the Netherlands at once, so re-measure anything reused from an earlier application. Head size and the eye line covers how the crown is defined.

The one fix. Shoot from further back and crop in. A phone at arm's length enlarges the nose and oversizes the head at once; a metre and a half away, cropped afterwards, fixes both.

2. Shadows behind the head and under the chin

What it means. GOV.UK asks that a photo "not have any shadows on your face or behind you". A shadow behind the head breaks the plain background; one under the chin or in the eye sockets hides the features being matched.

How to tell. Look at the wall beside both ears rather than at your face: if one side is darker, there is a shadow on it. Then look under the nose and jaw, where two dark wedges mean the light is above you, as a ceiling light is.

The one fix. Step away from the wall. A metre of gap lets the shadow fall out of frame. Face a window, with the window behind the camera, ceiling light off. The lighting guide covers the harder cases, including darker skin tones, where automatic exposure underexposes.

3. A background that is not plain

What it means. Two rules hide here. The background must be plain, with no pattern, doorframe or skirting board, and it must be the colour that authority names. Those colours disagree. The UK asks for plain cream or light grey and does not accept white; France forbids white and asks for light grey or light blue; the Netherlands allows grey, light blue or white; the United States asks for white or off-white, and Mexico for white.

How to tell. Check the top edge and upper corners, where a ceiling line or picture rail appears without anyone noticing. Then check the colour on the background guide rather than from memory.

The one fix. Find a blanker wall, or move further from the one you have so it falls evenly out of focus. Not a background-removal filter, for the reason below.

4. Softness, focus and resolution

What it means. The UK asks that the photo be "clear and in focus". Softness comes from low light, where the shutter slows and an outstretched arm smears the frame, from digital zoom, or from a front camera. Resolution fails separately: the UK asks for at least 600 × 750 px, a US visa upload for a square 600 × 600 to 1200 × 1200 px, a Canadian digital photo for 1800 × 1200 px.

How to tell. Open the image at 100% and look at the eyelashes and the edge of the iris. Lashes as a grey smudge rather than separate lines mean the photo is soft.

The one fix. Rear camera, held by someone else, in daylight: that fixes the sensor, the shake and the light at once. Mechanics in taking the photo with a phone, arithmetic in pixels and DPI and file size limits.

5. Expression

What it means. The UK wants "a plain expression and your mouth closed", as do Canada, France, Germany, the Netherlands, Ireland, Italy, Mexico and the Schengen standard. The United States is the only one here that allows a smile, and only with the mouth closed.

How to tell. Photos fail on a half-smile the person did not know they were making, rarely on a grin. Look at the corners of the mouth and whether any teeth show.

The one fix. Use a three-second timer rather than tapping the shutter, and let your face settle between frames. Babies are treated separately: UK children under six need not look at the camera or hold a neutral expression, and under-ones need not open their eyes, though no toy, dummy or supporting hand may appear. See baby photos and smiling.

6. Glasses

What it means. The United States has not accepted glasses in passport or visa photos since November 2016. The UK's wording is stricter than people expect: "Do not wear glasses in your photo unless you have to do so", and if you must, they cannot be tinted, and your eyes must not be covered by the frames or by any glare, reflection or shadow. Ireland, Canada, Italy, France, Germany and the Netherlands allow clear glasses on those conditions.

How to tell. Zoom into each lens. A white blob over the iris is glare, and a thick arm crossing the outer corner counts as the frame covering the eye, even where the pupil is visible.

The one fix. Take them off, unless there is a medical reason not to. Otherwise tilt the head slightly down and raise the light so the reflection falls below the eye. More in glasses in passport photos.

7. Signs of editing

What it means. Cropping and resizing to the published dimensions are what the application asks of you. Retouching is a different act: smoothed skin, whitened teeth, a replaced background, an "enhance" slider, a face cut out and pasted onto grey. Phones do some of it by default, in portrait mode and in beauty filters that ship switched on.

How to tell. Look at the outline of the hair against the background. A replaced background leaves a hard edge with strands missing and a halo of the old colour in the gaps. Then the skin: no pores anywhere is a filter.

The one fix. Shoot in plain photo mode with portrait mode and every beauty or "smart" enhancement off, and do not run the result through a background remover. It is why the tool here crops, measures and checks but never retouches your face, and why the background tool reports whether your wall is plain enough instead of replacing it. The rest is in the rules on AI and edited photos.

Where a machine decides

Some checks are no longer made by a person who can exercise judgement. Italy's passport office software rejects a non-compliant photo automatically, with no operator override, so a borderline head height there is a rejection, not a conversation. Several authorities have also closed the home-photo route: Germany has accepted only digital photos since 1 May 2025, taken at the authority or sent by the photographer; France requires a professional or an approved ePhoto booth; Canada requires a commercial photographer, with the studio's details stamped on the back, which no home print can satisfy. Check your country's page before spending an afternoon on a retake that is not eligible.

Setting up the retake

1. Daylight from a window in front of you, ceiling lights off, a metre between your shoulders and a plain wall.
2. Rear camera held by someone else, a metre and a half away, no zoom, plain photo mode, filters off.
3. Shoulders square, eyes on the lens, mouth closed, hair off the face, glasses off.
4. Plain clothing that contrasts with the background. Ireland bans uniforms, civil and military, including insignia; the US bans uniform-like clothing and camouflage. See what to wear and head coverings, allowed for religious or medical reasons with the face visible chin to forehead.
5. Crop to the country's format and measure the head in millimetres before you print or upload.

If you are printing at a shop, measure again on the paper: six 2 × 2 in photos fit a 4 × 6 in sheet exactly, 24 square inches into 24, so a borderless trim of a millimetre changes every head height on it. The sheet builder writes the real density into the file so the lab does not assume 72 DPI.

The checker, the UK and US crops and the DS-160 upload run in the browser tab, with no upload and no cap on attempts; the iOS app is free to download and gives one free export before asking for Pro, so use the web tool for repeated retakes. None of them can tell you a photo will be accepted, because that belongs to the issuing authority. They can tell you which of the seven faults your photo still has, in millimetres.
