Can You Smile in a Passport Photo? (2026 Rules by Country)
Short answer: no — most countries require a neutral expression with your mouth closed. A natural, very slight smile is sometimes tolerated, but a neutral face is always the safe choice and never gets rejected.
Why a neutral expression is required
Modern passports are read by facial-recognition systems at borders. These systems match a neutral face most reliably — a big smile distorts the distance between facial features and can trigger a mismatch. That's why authorities ask for a relaxed, neutral expression with both eyes open and the mouth closed.
What counts as "too much"
- Showing teeth — not allowed; a frequent rejection reason.
- A wide, open-mouth smile — not allowed.
- A faint, closed-mouth smile — often borderline; neutral is safer.
Rules vary slightly by country
The neutral-expression rule is near-universal. For exact size and background requirements, check your destination:
