Biometric Passport Photo: Requirements, Sizes by Country, and How to Get One Accepted (2026)
Understand biometric passport photo requirements, compare country sizes, and check lighting, head height and digital-file rules before you apply.

Quick answer: A biometric passport photo is an identity photo that meets the international face-image standards used for passports: ICAO Doc 9303, which relies on the technical standard ISO/IEC 19794-5. In practice that means a sharp, unedited, front-facing photo with your whole face visible, eyes open, a neutral expression, even lighting with no shadows, and a plain background, so that both a border officer and facial recognition software can match you to the picture. The standard sets the principles; each country then sets its own size and head height. A US photo is 2 × 2 inches with the head 1 to 1⅜ inches tall, a UK print is 45 × 35 mm with the head 29 to 34 mm, and an Australian photo is 35 to 40 mm wide and 45 to 50 mm high with a 32 to 36 mm face. A photo that is biometric-ready for one country can still be rejected by another, so always check the requirements of the authority that will issue your document.
Specifications in this guide come from official sources where I could verify them and from widely used summaries where I could not. Authorities change their rules, so confirm the current numbers on the official page for your document before you print or upload.
What Top Results for "Biometric Passport Photo" Leave Out
Search this keyword and you will mostly find photo-app vendors, photo studios, and generic guides. They usually agree on the basics (neutral expression, plain background, no glasses), but several practical gaps remain:
- Two meanings are blurred. A "biometric passport" is a passport with an embedded chip. A "biometric photo" is a photo that meets face-image quality rules. Many pages use the terms interchangeably, which confuses readers about what they actually need.
- One size is presented as universal. Many pages repeat 35 × 45 mm as if it applied everywhere. The US uses 2 × 2 inches, Canada uses 50 × 70 mm, and head-height ranges differ between countries.
- "Biometric" is treated as a guarantee. Some pages imply that a biometric photo is accepted anywhere. It is not: each authority applies its own size, background, and recency rules.
- The technical standard is rarely explained. Few pages say what the standard measures, such as a minimum of 90 pixels between the centres of the eyes, or how small the allowed head rotation is.
- Paper and digital rules are mixed together. Print size, pixel dimensions, file size, and print quality are different requirements. Some authorities specify paper type and printing method.
- Limits of online tools go unmentioned. Vendors rarely say that no tool can guarantee acceptance, or that some authorities advise against online services or apps.
This guide covers those points and gives you a checklist you can apply to any country.
What Is a Biometric Passport Photo?
A biometric passport photo is a photo prepared so that software can measure your face reliably. The word describes the photo, not the passport:
- Biometric photo: an image that meets face-image standards (pose, lighting, sharpness, resolution, background).
- Biometric passport, or e-passport: a passport with a chip that stores your data and your photo.
The two are linked, because the photo on an e-passport is read by machines. But you can need a biometric-quality photo for a passport, a visa, a residence permit, or an ID card. For the passport-chip side of the topic, see our guide to e-passport photos and the difference between biometric and digital passport photos.
What the International Standard Requires
ICAO's passport specification (Doc 9303) refers to ISO/IEC 19794-5 for the technical details of the face image. The practical requirements are:
| Requirement | What it means for your photo |
|---|---|
| Frontal pose | Face the camera directly. Head tilt and rotation are held to a few degrees; the ISO best-practice figure often cited is within ±5° |
| Eyes open and visible | No hair, glare, or frames covering the eyes. Both eyes on the same horizontal line |
| Face fully visible | No hair across the face; the edges of the face are clear |
| Resolution | For the image stored in the passport chip, ICAO guidance gives at least 90 pixels between the centres of the eyes, with 120 recommended; this is not a universal applicant-upload specification |
| Sharp and well exposed | In focus, natural skin tone, not too dark or too bright, no red-eye |
| Even lighting | No shadows on the face or background and no reflections |
| Plain background | Uniform, without patterns or objects. The exact colour is set by the country |
| No editing | No retouching, filters, or reshaping |
| Neutral expression | Mouth closed and a neutral look in many countries; check your authority |
The standard describes quality and geometry. It does not fix the print size or the exact head height in millimetres. Those come from the issuing country.
Biometric Passport Photo Requirements by Country
| Country or region | Print size | Head or face height | Digital submission | Other notes |
|---|---|---|---|---|
| United States | 2 × 2 in (51 × 51 mm) | 1 to 1⅜ in (25 to 35 mm) | For online passport renewal: original photo, JPG/JPEG/PNG/HEIC/HEIF, 54 KB to 10 MB; crop in the application | White or off-white background; taken within the last 6 months |
| United Kingdom | 45 mm high × 35 mm wide | 29 to 34 mm | At least 600 × 750 px, 50 KB to 10 MB, JPEG | Plain light-coloured background; taken within the last month; no digital alteration |
| Australia | 35 to 40 mm wide × 45 to 50 mm high | 32 to 36 mm (chin to crown) | Paper application with prints; check current rules | Less than 6 months old; dye-sublimation colour print on heavy glossy paper of at least 200 gsm; plain white or light background |
| EU and Schengen-style | 35 × 45 mm | Commonly 32 to 36 mm | Varies by country | For example, Finnish police guidance gives 32 to 36 mm; German visa guidance uses 35 × 45 mm |
| Canada | 50 × 70 mm | Check the official page | Check the official page | Larger than most countries; verify before printing |
Use this table as a comparison, not a final spec. The official page for your document is the authority, and rules for children, glasses, head coverings, and printing can differ.
One photo, many countries?
Not safely. A 35 × 45 mm photo will not meet the US 2 × 2 inch format, and a US square photo will not meet a 45 × 35 mm requirement. Even where sizes match, head height, background colour, and recency can differ. Take or prepare a photo for each document.
Printed vs. Digital: What Changes
Printed and digital photos follow different technical rules:
- Printed photos are judged on physical size, paper, print quality, and head height in millimetres. Some authorities specify the printing method and paper weight, as Australia does.
- Digital photos are judged on pixel dimensions, file format, file size, and compression. The UK, for example, sets a minimum of 600 × 750 pixels and a 50 KB to 10 MB range, while US online passport renewal requires an original photo in an accepted format, 54 KB to 10 MB, with cropping available in the application. The 600–1200 pixel square and 240 KB limit belong to US visa uploads, not a universal US passport requirement.
- Both must pass the same face-image rules: pose, expression, lighting, and background.
Do not submit a scan or photo of a printed photo for an online application unless the authority allows it. Upload a clean, original digital image.
How to Take a Biometric Passport Photo at Home
- Read the official requirements for your document. Note size, head height, background, and recency.
- Choose a plain background. Use a plain wall in the colour your authority requires, and stand a short distance in front of it to avoid shadows.
- Use even, diffuse light. Face a window or use two lights at equal angles. Avoid direct sun and overhead light that casts shadows under the eyes.
- Place the camera at eye level. Use a tripod or a stable surface, and have someone else take the photo if you can.
- Stand square to the camera. Keep your head upright and level, shoulders square, and look straight into the lens.
- Keep a neutral expression. Mouth closed, eyes open, no tilt.
- Remove what you should not wear. Take off glasses unless an exception applies, and keep hair and accessories off your face.
- Take several shots. Choose the sharpest one.
- Crop and size it correctly where permitted. Match the dimensions and head height, and avoid retouching. For UK online applications using your own device, do not crop the photo yourself; for US online passport renewal, crop within the application.
- Check the result against the requirements before you print or upload.
For children and infants, rules are often relaxed, but the photo still has to meet the main requirements. Australian guidance, for example, allows an open mouth for children under three but does not allow anyone else to be visible.
Biometric Passport Photo Checklist
Before you submit, confirm that:
- The size matches your authority's requirement.
- Head height falls in the allowed range.
- The face is centred and looks straight at the camera.
- Both eyes are open and clearly visible.
- The expression is neutral, as your authority requires.
- Hair does not cover the face, eyes, or the edges of the face.
- The background is plain, uniform, and the right colour.
- There are no shadows on the face or background.
- There are no reflections on glasses, jewellery, or skin.
- The photo is sharp, well exposed, and has natural skin tone.
- The photo is recent enough for your authority.
- The image has not been retouched, filtered, or reshaped.
- For digital files, pixel size, format, and file size are within the limits.
- For prints, the paper and print quality meet the rules.
Common Reasons Biometric Photos Are Rejected
| Problem | Why it fails | How to fix it |
|---|---|---|
| Shadows on the face or background | Shadows hide facial features and background uniformity | Use even, frontal light and move away from the wall |
| Head tilted or turned | Pose is outside the allowed tolerance | Square your shoulders and level your chin |
| Eyes not fully open or hidden | Eyes must be visible for matching | Open your eyes naturally, remove glare, move hair |
| Wrong size or head height | The crop does not match the specification | Use the official size and measure the head |
| Blurry or low resolution | Software cannot measure the face reliably | Focus carefully and use a higher-quality image |
| Non-plain or wrong-colour background | Background must be uniform and the specified colour | Use a plain wall or sheet and check the colour |
| Retouching or filters | Images must be unaltered | Retake the photo without editing |
| Glasses with glare or frames over the eyes | Eyes are obscured | Remove glasses unless an exception applies |
| Photo too old | Appearance may differ from now | Take a new photo within the allowed period |
Professional, DIY, or Online Service?
| Option | Good for | Watch out for |
|---|---|---|
| Professional studio or post office | Paper applications and authorities that recommend professionals | Cost and travel; confirm they use your country's specification |
| Photo booth | Quick prints | Booth settings may not match the specification, and some systems reject booth photos |
| DIY with a phone | Digital applications where you can control light and framing | Lighting and cropping errors; no independent check |
| Online passport photo service | Digital photos with a compliance check | No service can guarantee acceptance; the authority decides, and some, like Australia, recommend against online services or apps for paper applications |
Match the option to your document. If your authority accepts digital photos, a service that checks size, background, and face-image rules can save a rejected application. If it requires professionally printed photos, use a professional provider.
Frequently Asked Questions
What is a biometric passport photo?
It is a passport-style photo that meets face-image standards so that people and software can match your face to the picture: front-facing, neutral expression, plain background, even lighting, and the correct size for your country.
Is a biometric passport photo different from a regular passport photo?
In most countries, a regular passport photo has to meet the biometric standards, so the two are effectively the same. The practical difference is that "biometric" emphasises technical quality, such as pose, lighting, and resolution.
What size is a biometric passport photo?
It depends on the country. The US uses 2 × 2 inches, the UK uses 45 × 35 mm, and EU and Schengen-style photos are commonly 35 × 45 mm. Check the official page for your document.
Can I take a biometric passport photo at home?
Many authorities accept home-taken digital photos if they meet the requirements, but some recommend professional photographers for paper photos. Check your authority's guidance first.
Can I smile in a biometric passport photo?
Many authorities require a neutral expression with the mouth closed, including the UK and Australia. Check your authority's rules.
Do I have to take off my glasses?
Often yes. Australian guidance, for example, does not allow glasses unless they cannot be removed for medical reasons. Check your country's rules.
How recent must the photo be?
It depends. Australia requires photos less than 6 months old and the US requires a photo taken within the last 6 months, while UK guidance requires a photo taken within the last month. Check the exact period.
Can I use the same photo for my passport and my visa?
Not always. Passport and visa photos can have different sizes and rules, so use the specification for each document.
Can I edit or retouch my passport photo?
No. Authorities reject photos that are retouched or filtered. Crop and resize only where the application instructions allow it; UK online applicants using their own device should not crop the photo themselves. Do not alter your appearance.
The Bottom Line
A biometric passport photo is less about a special kind of photo and more about meeting a strict set of face-image rules and then your country's specific size and format. Learn the rules for your authority, take the photo in even light against a plain background, and check size, head height, and file requirements before you submit. If you want a second pair of eyes before you apply, check your photo against the requirements for your document first.
