Can You Smile in a Passport Photo? Expression Rules Explained
By Passport Photo Template Editorial Team | Published and reviewed June 29, 2026 | 8 minute read
Quick answer
The safest adult expression is neutral: face forward, eyes open, mouth closed and no smile or frown. The United States, United Kingdom, Australia and New Zealand all publish neutral-expression rules. Age-based exceptions exist, but the ages and exact wording are not identical.
Why expression matters
A passport image is used for identity comparison, not as a social portrait. A broad smile lifts the cheeks, narrows the eyes and changes the outline around the mouth. A frown also changes facial landmarks. A neutral expression gives human examiners and biometric systems a more stable reference.
Neutral does not mean looking angry. Relax the forehead and jaw, keep both lips together without pressing them tightly, and look at the camera lens. Take the picture after a normal breath so the shoulders and neck are not tense.
Rules differ in small but important ways
| Authority | Published adult rule | Child exception highlighted |
|---|---|---|
| United States | Neutral expression, both eyes open and visible, mouth closed | Check the current child examples and application guidance |
| United Kingdom | Plain expression, mouth closed | Under 6 need not have a plain expression; under 1 need not have eyes open |
| Australia | Neutral expression, eyes open, mouth closed for anyone over 3 | Under 3 may have the mouth open |
| New Zealand | Neutral expression, no smiling, mouth closed, eyes open | Baby instructions still require the full face and no other person |
This table is a comparison, not a substitute for the form you are submitting. Visa rules can also differ from passport rules issued by the same country.
Does a tiny smile count?
People often ask whether a closed-mouth half-smile is acceptable. The practical problem is that the answer depends on how the authority evaluates the specific image. If the published instruction says neutral, do not plan around the maximum smile an examiner might tolerate. Retake the frame with relaxed lips instead.
The UK's internal photo standards indicate that examiners consider whether an expression changes the shape of the face, but the public applicant instruction remains a plain expression with the mouth closed. Following the public rule is simpler and carries less risk than trying to predict discretion.
Teeth, open mouth and talking
Visible teeth usually mean the mouth is open or the person is smiling. Both conflict with the common adult rule. Talking during the shutter can also produce an asymmetric mouth. Ask the photographer to count down, then stay silent until the picture is taken.
Do not digitally close the mouth or reshape a smile. That creates an edited likeness and can produce unnatural edges. Capture a new frame instead.
Eyes and blinking
Both eyes should normally be open, visible and looking toward the camera. Take multiple frames in quick succession rather than trying to repair a blink. Reflections, heavy hair, tinted lenses and deep shadows can make an open eye appear hidden.
If a medical condition prevents compliance, follow the authority's medical-exception process. Do not invent a workaround with image editing. Supporting documents may be required depending on the country.
How to get a natural neutral expression
- Sit or stand comfortably with shoulders level.
- Look directly into the camera lens, not at your own preview.
- Relax the forehead and let the lower jaw rest naturally.
- Bring the lips together gently without pursing them.
- Keep the chin level and do not tilt the head.
- Have the photographer take several frames and select the clearest neutral one.
Children need patience, not digital correction
Use the child rule for the relevant country and age. The UK explicitly relaxes the plain-expression rule for children under 6. Australia allows an open mouth for children under 3. These are not universal permissions to use a laughing or crying photograph.
Remove toys, dummies and visible supporting hands when the authority requires the child to appear alone. Our baby and child passport photo guide compares the capture exceptions in more detail.
Expression checklist
- Face is straight toward the camera.
- Head is level, without rotation or tilt.
- Both eyes are open and clearly visible unless an official age or medical exception applies.
- Mouth is closed and teeth are not visible.
- No smile, frown, raised eyebrow or exaggerated expression changes the face.
- The expression was captured naturally, not edited afterward.
