The finished photo is 40 × 50 mm, which is 472 × 591 pixels at 300 DPI.
From the bottom of the chin to the top of the hair, the head is 30–37.5 mm (60–75% of the height).
The background is plain and even: white or light, with no pattern, texture or shadow behind the head.
Face the camera straight on, with a neutral expression, mouth closed and both eyes open.
Take glasses off. A few offices still accept clear lenses, but most biometric checks reject reflections and frames, so removing them is the safe choice.
Light the face evenly, with no shadow across it and no bright spot on the forehead.
Keep hair away from the eyes. Religious head coverings are accepted if the face from chin to forehead stays visible.
Use a recent picture - most authorities say within the last six months - and do not retouch or filter the face.
These figures follow the issuing authority's published specification. Confirm with the Hong Kong authority before you apply.
