Hong Kong ID card photo requirements 2026: what the Smart Identity Card needs and why it is not the same as a passport photo

The practical answer

The Hong Kong Smart Identity Card requires a printed colour photograph measuring 29mm wide by 35mm tall. The photo must have been taken within the last six months and must show a full frontal view of your face from the top of the head to the chin. The head height from chin to crown should be at least 27mm, with at least 2mm of clear space between the top of the head and the top edge of the photo. The background must be plain white or near-white. The expression must be neutral with both eyes open, facing directly at the camera. Glasses are not permitted. Religious head coverings are permitted; other headwear is not. The photo must be printed on good quality photo paper, whether glossy or matte, and must be a colour photograph — not black and white, not a printout on plain paper. For digital submissions through the ImmD's online services or mobile app, the file must be a JPEG with a minimum resolution of 1200×1600 pixels at the same proportional crop as the printed photo. The maximum file size is 5MB. The same composition rules apply to digital submissions as to printed photos: white background, head height filling the majority of the frame, neutral expression, no glasses.

Where people get surprised

The single biggest source of confusion is the size difference. Many Hong Kong residents who have recently renewed their passport arrive at the Registration of Persons Office with the 40×50mm passport-format photographs they had taken at the same time, assuming one session would cover both documents. It does not. The HKID card uses a noticeably smaller 29×35mm format, and the aspect ratio is slightly different from a passport photo as well — passport photos are roughly 4:5, while the HKID photo is closer to 29:35 or approximately 5:6. A photo printed at 40×50mm and trimmed to 29×35mm will not have the correct composition, because the face will be incorrectly positioned relative to the frame edges. You need a photo prepared specifically for the HKID dimensions. The second thing that surprises people is the glasses rule. Hong Kong passport photos banned glasses some years ago, and most people who regularly update their documents are aware of this. But applicants who have not gone through the process recently, or who are applying for their first HKID card as a young adult, sometimes arrive wearing glasses. The rule is the same as for the passport: glasses must be removed. Clear frames with no tint and no visible lenses are still not permitted. The photo must be taken with no glasses at all, unless a signed medical statement from a licensed medical professional confirms that the glasses cannot be removed for a specific documented medical reason. In practice this exception is very rarely used. The third issue is background tone. The ImmD specifies plain white, and unlike the New Zealand requirement which explicitly recommends off-white or light grey for biometric contrast, Hong Kong's standard is plain white or very near white. A beige or cream background that might pass for New Zealand or Australian requirements could create contrast issues at the ImmD officer's desk. If you are taking the photo at home, use the whitest wall you have, or hang a piece of white card or fabric behind you. Soft, even lighting from a natural window source works well — what you want to avoid is a shadow falling on the white background from the subject or from the lighting angle, which will make the background appear grey or uneven.

Why 40×50mm passport photos cannot simply be trimmed

A frequent question that arises among applicants who already have extra HKSAR passport photos is whether they can take a ruler and paper cutter to trim a 40×50mm photograph down to 29×35mm. While this might seem like a simple mathematical crop, it almost invariably results in an immediate rejection at the Registration of Persons Office counter. The primary reason trimming fails is biometric centering. On a standard 40×50mm HKSAR passport photograph, the face from chin to crown occupies between 32mm and 36mm, leaving substantial vertical margin above the hair and below the neckline to accommodate the passport page layout. In contrast, the HKID Smart Identity Card requires a 29×35mm frame where the chin-to-crown distance must be at least 27mm. If you take scissors or a trimmer to a 40×50mm print and slice off 11mm in width and 15mm in height, you will either sever the top of the crown, cut into the chin, or leave the facial features severely decentered with zero margin. The ImmD specification strictly mandates a minimum of 2mm of clean white space above the crown. Trimming down an existing passport photo inevitably eliminates this mandatory headroom. Furthermore, registration officers at the RPO utilize calibrated plastic templates and digital overlay calipers during counter verification. Hand-cut edges rarely maintain perfect 90-degree right angles or exact millimeter tolerances. When an officer places a hand-trimmed photograph into the verification overlay, jagged cuts or uneven borders are immediately evident, prompting the officer to reject the print and instruct the applicant to obtain a newly framed photograph before processing can continue.

Clothing, hair, and facial appearance guidelines

Ensuring your attire and hairstyle conform to ImmD expectations avoids unexpected friction during your appointment. Because the Smart Identity Card features an advanced polycarbonate substrate with laser engraving technology, the initial colour capture must exhibit clean tonal separation between the applicant and the white backdrop. **Clothing selection:** The Immigration Department explicitly advises applicants to avoid wearing pure white or extremely pale tops. A white shirt or blouse merges into the white background, causing your shoulders and neckline to visually disappear, which corrupts edge-detection biometrics during card engraving. Conversely, tops with excessively deep V-necks or low cuts can make the applicant appear unclothed in the tight 29×35mm frame. The optimal choice is a solid, medium-to-dark-toned collared shirt, polo, or crew-neck top. Avoid complex geometric patterns, prominent brand logos, or reflective metallic fabrics that could bounce flash and cause glare. **Hairstyle and facial visibility:** Your full face must be unobstructed from chin to forehead. Bangs or fringes should be neatly swept aside so that both eyebrows are clearly delineated. While ears do not necessarily need to be fully visible if covered by natural long hair, your facial contours — including the outer edges of your cheeks, temples, and jawline — must remain visible without hair casting dark shadows across your features. Ponytails or hair ties should remain unobtrusive behind the head. Hair accessories such as wide headbands, decorative clips, or ribbons are prohibited. **Makeup and cosmetic appearance:** Everyday natural makeup is acceptable, provided it does not alter your authentic facial structure. Avoid heavy contouring that simulates non-existent bone shadows, dramatic eyeliner that obscures eye shape, or excessively glossy lipsticks that produce specular highlights under photographic lighting. Matte foundations that match your natural skin tone produce the cleanest result under registration office scanners.

In-person Registration of Persons Office (RPO) photo handling

When attending an appointment at one of the Registration of Persons Offices — whether at the Immigration Tower in Wan Chai, Kowloon Office in Sham Shui Po, Kwun Tong, Fo Tan, or Tuen Mun — knowing how your physical photo is handled will help you prepare. When you arrive for a first-time registration, replacement for lost or damaged card, or amendment of registered particulars, you will typically be guided to an interview booth or a self-service registration kiosk. At the counter, the registration officer will ask for your printed photographs. You should bring two identical, unmounted 29×35mm prints produced on high-resolution photographic paper. The prints must be clean, uncreased, and completely free from staple marks, paperclip indentations, or ink smudges. Do not write your name, HKID number, or date on the back of the prints using a ballpoint pen, as the pressure can emboss through the paper and create visible ridges across your face on the front surface. For certain Smart Identity Card renewal categories where automated photo capture booths are provided on-site, having your own compliant 29×35mm prints ready remains essential in case on-site kiosks are unavailable, experience technical difficulties, or fail to produce an image you find satisfactory. Bringing compliant pre-printed photos gives you full control over your appearance and ensures your registration appointment proceeds smoothly without unnecessary delays.

Before you take the photo

Use a plain white wall as your background, or hang a sheet of white card or fabric if the walls in your space are off-white or cream. The ImmD standard is white — not near-white, not light grey — so the closer to pure white your background is, the less risk of a background colour rejection at the registration desk. Remove your glasses before you open the camera. HKID photo rules do not permit glasses of any kind, including clear prescription frames. If you forget and only notice after reviewing the shot, the fix is simply to take off the glasses and shoot again rather than trying to reframe or crop around the issue. The whole point of catching this before you print or upload is that reshooting at home costs nothing, whereas discovering it at the ImmD office or after uploading means starting over. Take the photo from roughly 1 to 1.5 metres away using the rear camera on a phone or a compact digital camera. At this distance, the perspective is relatively flat and avoids the facial distortion you get from a close-up shot. A selfie taken with the front camera at arm's length will introduce some barrel distortion at the edges of the face — usually subtle, but it can affect the apparent proportions when the image is cropped to 29×35mm. If there is someone in the household who can operate the camera while you stand against the background, use them. Check the lighting carefully before you finalise the shot. What you want is soft, even illumination from the front — ideally from a window to your side, or two light sources on either side of your face to eliminate shadows. Avoid shooting with a single light source directly above you, which will cast a shadow under your chin and nose. Avoid shooting with a window directly behind you, which will make your face appear dark against a bright background. If you are using the PassSnap guided capture, the head size indicator will confirm the framing, but the lighting check is on you before you press the shutter. Check the photo on a full-size screen before deciding it is ready. On a phone preview, a slightly uneven background or a small shadow under the chin can look perfectly fine. On a laptop or tablet at full size, the same issues become much more visible. The ImmD officer will review the printed photo under good lighting, so if you can see a problem on a larger screen, they will too. A reshot at home costs nothing; a rejected photo at the registration office means another appointment. If you are preparing a digital submission through the ImmD's online services or mobile application, verify the JPEG file size before uploading. The maximum accepted file size is 5MB and the minimum resolution is 1200×1600 pixels. A photo taken on a modern smartphone in standard camera mode will typically meet these requirements without additional resizing, but if you have applied any compression or format conversion, check the file properties before submitting.

How PassSnap fits

PassSnap 2.0 includes a Hong Kong photo type that applies ImmD-compliant crop dimensions and face-size guidance. The HKID Smart Identity Card template uses the 29×35mm format with the correct head height targets and margin requirements built in, so the guided capture shows you whether the framing meets the specification before you commit to a shot. The optional AI verify step checks for glasses, expression, and background compliance before export. The exported JPEG meets the digital submission resolution requirements for the ImmD online and mobile services, and the print layout produces correctly sized prints on a standard photo sheet. By guiding you through lighting, framing, and head proportion in real time, PassSnap eliminates the guesswork of navigating ImmD's unique card dimensions. The exported print layout allows you to print multiple 29×35mm copies onto standard 4×6 photo paper at any local photo lab or convenience store, complete with precise cutting guides that ensure your physical prints meet counter requirements flawlessly.
