Hong Kong SAR passport photo requirements 2026: what the IMMD requires
HKSAR passport photos are governed by the Immigration Department (入境事務處, IMMD) and differ from most other markets in two important ways: the format is 40×50mm rather than the international ICAO standard of 35×45mm, and clear prescription glasses are permitted — as long as there is no tint and no glare on the lenses. These two differences mean that standard passport photo advice written for the US, UK, or Australian markets will give incorrect specifications for a Hong Kong application. Getting the size and the glasses rule right before shooting prevents the most common rejection causes.
Key takeaways
- “hong kong passport photo requirements” combines physical size, head-percentage, background, expression, file format, and recency rules.
- Confusing physical (mm) and digital (px) size is a common mistake.
- Head-percentage is the rule that catches the most photos.
- Background expectations vary by authority, not just “white”.
- Glasses are banned for most major authorities.
- Six-month recency is the default unless appearance has not changed.
The practical answer
HKSAR passport photos must be 40mm wide × 50mm high. The face from chin to crown must measure 32–36mm, with appropriate headroom above the crown. The background must be white. The photo must be a colour close-up showing the full face clearly. For digital applications via the IMMD's online portal or mobile app, the file must be a JPEG of 5MB or below, at a digital image size of 1200 × 1600 pixels (from a digital camera) or equivalent from a 600dpi scanner. Prescription glasses are permitted if the lenses are completely clear (no tint, no colour, no photochromic tint that appears light indoors), and there is absolutely no glare on the lenses. Clothing should not be pure white (to contrast with the white background) and should not be too dark or too light. There is no explicit rule against a natural smile, but an exaggerated or unusual expression may be rejected.
Where people get surprised
Three things catch applicants. First, the size: 40×50mm is unique to Hong Kong SAR. The US uses 51×51mm (square), the UK and Australia use 35×45mm, and Canada uses 50×70mm. Using any other country's format for an HKSAR application will result in immediate rejection. Second, the glasses rule: unlike the US, Australia, and New Zealand — which all prohibit glasses entirely — Hong Kong permits clear prescription glasses. But "clear" means genuinely clear: photochromic lenses that appear transparent indoors still fail because they have a residual tint under certain lighting. Blue-light-blocking coatings with a visible yellow or orange tint also fail. Third, clothing: IMMD explicitly advises against wearing pure white clothing (it blends with the white background) and against very dark or very light colours generally. A solid medium-tone colour with a proper collar is the standard recommendation.
How PassSnap fits
PassSnap 2.0 supports the HKSAR Passport photo type with the correct 40×50mm crop and 1200×1600px digital export. The app's guided capture includes framing guidance for the 32–36mm face height requirement. The optional AI verify step checks for lens glare and tint — a specific check for the Hong Kong market where glasses are permitted but must meet exact optical conditions.
In-depth notes
Why “hong kong passport photo requirements” is harder than it looks
The complexity behind “hong kong passport photo requirements” is that the rules look simple individually but combine into a tight target. Get framing right, lighting wrong, and the result fails. Get lighting right, miss head-percentage, and it fails. The compound probability of getting every rule right in a single shot is what makes most first attempts fail. The fix is not better luck; it is a capture process that controls each rule before the shutter, not after.
- Each rule is easy in isolation but compounds quickly
- First-attempt failure is the rule, not the exception
- Process-based capture beats trial-and-error
- Reviewing the export file (not preview) catches most issues
What automated review actually checks for “hong kong passport photo requirements”
Modern automated review for “hong kong passport photo requirements” uses biometric facial landmark detection plus background uniformity analysis. The system measures head height in pixels, eye-line position, mouth state, eye openness, glasses presence, and background colour variance. Photos that pass automated review still face human review for expression and visual quirks that the algorithm misses. Passing both rounds requires a photo that is technically compliant and visually clean.
- Biometric facial landmark detection
- Background colour variance analysis
- Eye openness and gaze direction
- Glasses, head covering, and mouth detection
- Human review for visual quirks after automated pass
Recovery if the first “hong kong passport photo requirements” attempt fails
If a “hong kong passport photo requirements” submission was rejected, the fastest recovery is to identify which specific rule failed. The rejection notice usually says “head too small”, “background not uniform”, “glasses detected”, or similar. Each maps to a specific capture adjustment. Re-shooting with a targeted fix takes minutes. Resubmitting the same photo with a different file format almost never succeeds.
- Read the rejection notice for the specific rule
- Map the rule to a capture adjustment
- Re-shoot rather than re-export
- Use AI verify to catch the same rule before resubmission
- Keep the original capture for comparison
Authority spec comparison for “hong kong passport photo requirements”
Key spec differences across the five most common authorities.
| Authority | Print size | Digital | Head size | Background |
|---|---|---|---|---|
| United States | 51×51mm | 600-1200 px square | 50-69% of image | Plain white to off-white |
| United Kingdom | 35×45mm | 600×750 px | 29-34mm face | Plain light grey / cream |
| Canada | 50×70mm | 715-2000×1000-2800 px | 31-36mm face | Plain white |
| Schengen | 35×45mm | 413×531 px @ 300dpi | 29-34mm face | Uniform light |
| Australia | 35×45mm | Varies | 32-36mm face | Plain light |
Before you take your HKSAR passport photo
- Wear a solid-coloured top with a proper collar in a medium tone. Avoid pure white (blends into the background), very dark, and very light colours. IMMD explicitly advises against all three.
- If wearing glasses, confirm the lenses are completely clear with zero tint. Photochromic lenses that look clear indoors, blue-light coatings with any colour cast, and lightly tinted lenses all fail the requirement. Test in the actual shooting light before you start.
- Ensure there is no glare anywhere on the lenses before pressing the shutter. Adjust the light source position — even a small rotation of the head can eliminate glare without changing the face-on requirement.
- For digital upload via the IMMD online portal or app, export a JPEG at 1200×1600 pixels, 5MB or below. The portal checks file size on upload — oversized files will be rejected immediately.
- Do not fold the photo, attach it with a staple or paperclip, or write on the back. IMMD uses laser engraving to transfer the photo to the passport; any physical damage to the print affects the final passport quality.
Glossary
- Head-percentage
- The ratio of the face from chin to crown to the total image height. US wants 50-69%; UK and Schengen want 29-34mm face within a 45mm image; Canada wants 31-36mm.
- Biometric placement
- Automated facial landmark detection that measures eye-line position, head height, and face orientation. Used by digital application portals to validate uploads.
- Upload JPEG
- The digital photo file submitted to an application portal, at the exact pixel dimensions and file size required by the authority.
- 4×6 print sheet
- A standard photo paper layout that packs multiple copies of the document-sized photo onto a 4×6 inch sheet for home or lab printing.
- AI verify
- An optional risk review that checks the final photo against spec rules (glasses, expression, ears, background) before submission. Does not guarantee acceptance.
FAQ
Can I wear glasses in a Hong Kong SAR passport photo?
Yes — but with strict conditions. The lenses must be completely clear (no tint of any kind, including photochromic, blue-light, or UV coatings that have a visible colour cast), the frames must not obstruct the eyes, and there must be absolutely no glare on the lenses. If any of these conditions cannot be met, removing the glasses is simpler than risking a rejection. The US, Australia, and New Zealand all prohibit glasses entirely — Hong Kong SAR is one of the few markets where they remain permitted.
What size is a Hong Kong SAR passport photo?
40mm wide × 50mm high — a unique format not shared by any other major passport-issuing country or territory. The face from chin to crown must be 32–36mm within that frame. For digital submissions, the image size is 1200 × 1600 pixels as a JPEG file of 5MB or below.
Does PassSnap support the Hong Kong SAR passport photo format?
Yes. PassSnap 2.0 includes a dedicated HKSAR Passport photo type with the correct 40×50mm crop, 1200×1600px digital export, and AI verify that includes a lens glare and tint check specific to the Hong Kong market. Visit passsnap.app/supported-photo-types for full details.
