Passport photo rules look fussy until you understand why they exist: modern passports use your photo for automated facial-recognition checks at e-gates and border control, and a photo that's too dark, off-centre, smiling, or wearing glasses with glare can fail that automated match years later at a border, not just at the application stage. The rules below are the common standards across most countries — always confirm the exact specification with your own country's passport authority before submitting, since sizes and details do vary.
Size and framing
Most countries specify a fairly precise photo size (commonly around 35mm x 45mm for many countries, though the US and a number of others use a 2x2 inch / 51mm square format) along with rules for how much of the frame your head and face must fill — typically requiring your face to take up a specific proportion of the photo's height, measured from chin to crown, with defined margins above your head and below your chin. A photo taken too close, too far away, or off-centre is one of the most common reasons applications are rejected or delayed, so precise framing matters more than photo quality alone.
Background
A plain, light-coloured background — usually white, off-white or light grey — is close to universal, with no patterns, shadows, other people, or objects visible behind you. Shadows cast onto the background from overhead lighting are a common, avoidable failure: even lighting from the front, without a strong single light source above or to one side, avoids this. Photos taken against a patterned wall, a car interior, or outdoors with visible background clutter are routinely rejected.
Expression and eyes
A neutral expression is the standard requirement — mouth closed, no smiling, and both eyes open and clearly visible, looking directly at the camera with your head facing forward, not tilted or turned. This exists specifically because facial-recognition systems used at automated border gates are calibrated against a neutral, forward-facing reference, and a strong smile or an angled head measurably reduces match accuracy in some systems. Glasses are increasingly discouraged or banned outright in many countries' current rules, largely because of glare and reflections interfering with the same recognition systems — check your specific country's current rule on glasses before your appointment, since this has tightened in a number of places in recent years.
Babies and young children
Passport photos for babies and young children follow the same neutral-expression and framing principles, which is exactly why they're notoriously difficult — a baby who won't hold still, keep their eyes open and stay expressionless on demand makes an already fussy standard harder to meet. Common practical approaches include laying the baby on a plain white sheet or blanket and photographing from directly above, or having another person hold the baby against a plain background just out of frame, cropping them out afterwards. Other people, including a supporting hand, must not be visible in the final photo, and the baby's eyes need to be open and looking roughly at the camera — patience and several attempts are normal here, not a sign you're doing it wrong. See our guide to do babies and children need a passport? for the wider documentation requirements around infant travel.
Digital vs printed photos
Many countries now accept or require a digital photo uploaded directly during an online application, alongside or instead of a printed photo for in-person applications, and the technical specification (file format, resolution, file size limits) for digital submissions is usually stricter and more specific than for a printed photo, since it feeds directly into the passport's chip and any automated verification system. If you're applying online, use your country's official photo-checking tool if one is offered — many passport authorities provide a free automated check that flags framing, lighting or expression issues before you submit, catching problems a human reviewer might not until weeks later.
Where to get a compliant photo
Pharmacies, photo shops, post offices and dedicated passport photo booths in many countries offer photos taken specifically to the current national specification, and this is generally the most reliable option if you're not confident doing it yourself — most will redo the photo on the spot if it doesn't meet the standard. Phone apps that guide you through taking a compliant photo at home exist and can work well, but they rely on you following the guidance precisely (background, lighting, distance) and a photo rejected after submission costs more time than getting it right with professional help the first time, particularly if you're on a deadline. If time is tight, our guide to how to renew a passport fast covers what else affects turnaround beyond just the photo.
Common reasons photos get rejected
- Smiling, an open mouth, or a tilted head instead of a neutral, forward-facing expression.
- Shadows on the background or on the face from uneven lighting.
- Glasses causing glare, or being worn where the current rule now discourages or bans them.
- Incorrect framing — head too large, too small, or off-centre in the photo.
- A background that isn't plain and light-coloured, including visible furniture, patterns or other people.
- A photo that's too old — most countries require the photo to have been taken within the last six months.
A wrong or non-compliant photo is a paperwork problem, easily fixed by retaking it — a different category of issue from your passport itself being damaged, which is covered in our guide to travelling with a damaged passport. And if the name on your existing documents doesn't match a new booking or visa, that's a separate issue again — see name on ticket doesn't match your passport.
Frequently asked questions
Can I smile in a passport photo?
No, almost universally. A neutral expression with a closed mouth is required, largely because facial-recognition systems used at automated border gates are calibrated against a neutral reference and a smile can reduce match accuracy.
Can I wear glasses in my passport photo?
Increasingly discouraged or banned outright in many countries' current rules, mainly due to glare interfering with facial recognition. Check your specific country's current guidance before your appointment.
How do I get a compliant photo of a baby?
Lay the baby on a plain white sheet and photograph from above, or have someone hold them against a plain background and crop them out — the same neutral-expression and open-eyes rules apply, and several attempts are normal.
How old can a passport photo be when I submit my application?
Most countries require the photo to have been taken within roughly the last six months, reflecting how quickly appearance can change, particularly for children. Check your specific country's rule, as this does vary.
