The UK visa photo: what the upload wants, not what the print wants
UKVI publishes a separate rule set for the digital photo you upload, and it is not the 35 × 45 mm print specification that travel guides quote. The upload is judged in pixels and kilobytes; the print is judged in millimetres on paper.
The published digital rules
| Property | Rule as published | What goes wrong |
|---|---|---|
| Format | jpg or jpeg | PNG, HEIC and PDF fail before anything else is checked |
| Minimum pixels | At least 600 pixels wide and 750 pixels tall | Not a square. A file cropped to 1:1 is the wrong shape for this form |
| File size | At least 50 KB and no more than 6 MB | Both ends are enforced. An aggressively compressed 30 KB file fails on the floor |
| Orientation | Vertical, and not mirrored or flipped | Selfie cameras mirror by default; a mirrored file is rejected outright |
| Background | Plain, light-coloured, in clear contrast to the subject | Grey walls, door frames and shadows fail |
| Content | Head, shoulders and upper body; no other people or objects | A tight face-only crop is too little; a waist-up portrait is too much |
| Processing | Not altered by software or by any filter | Beauty filters and background removal are excluded by the same sentence |
| Glasses | Only if you have to wear them; no tinted or sunglasses lenses; no glare over the eyes | Glare across the pupil is the most common glasses failure |
| Source | Not a scan or photograph of another photograph; not the photo already in your passport or ID card | Reusing the passport image is explicitly barred |
Why the 35 × 45 mm figure keeps appearing
35 × 45 mm is the frame used for UK passport photographs and for a printed photo attached to a paper application. It is a real specification, published by HM Passport Office, and it is correct in that context. It is simply not the specification the digital upload enforces.
The two are checked against different artefacts. A print is measured with a ruler against a millimetre frame; an upload is measured in pixels and bytes by a form. A file that satisfies "35 × 45 mm at 300 DPI" is 413 × 531 pixels, which is below the 600 × 750 pixel floor — so a perfectly correct print export can be rejected by the upload for being too small. That is the failure people report as "my photo is the right size but the site will not take it".
Children and babies
- Children must be alone in the photo, with no toys or dummies.
- Under six: they do not have to look directly at the camera or hold a plain expression.
- Under one: eyes need not be open, and a supporting hand may hold the head — but the hand must not appear in the frame.
- Under one: lie the baby on a plain light-coloured sheet and photograph from above.
These relaxations apply to the digital upload. They do not relax the byte floor: a photo that has been resized down for a messaging app often lands under 50 KB.
Where this sits among the UK's other photo rules
The UK is the clearest example of a country whose official pages do not agree on every ceiling: passport photos, visa uploads and third-party collection systems each publish their own. Rather than average them, portal upload limits lists each ceiling with the page it came from. The print specifications, including the 35 × 45 mm frame and the head-size rule, are on the UK page.
