No, not a wide smile. GOV.UK asks for a plain expression with your mouth closed (GOV.UK: Get a passport photo). HM Passport Office's examiner guidance rejects photos where you're smiling widely, pouting or frowning, because that changes the shape of your face, but accepts a relaxed mouth with teeth showing slightly, as long as your features aren't distorted (GOV.UK: HM Passport Office photo standards (examiner guidance, March 2026)).
GOV.UK's photo rules and HM Passport Office's photo standards checked on 3 November 2026. Fees and rules change, so check the linked GOV.UK page before you pay.

| Expression | UK passport photo |
|---|---|
| Plain expression, mouth closed | Accepted |
| Relaxed mouth, lips slightly open or teeth just visible | Accepted, if your face isn't distorted |
| A slight, closed-mouth smile that doesn't change your face | May be accepted; a plain expression is safer |
| Wide smile, grin, pout or frown | Rejected |
| Mouth open because of a medical condition | Accepted |
| Children under 6 | Don't need a plain expression or to look at the camera |

Your photo is read by face-matching systems at borders. An expression that changes the shape of your face can stop the system capturing accurate measurements (GOV.UK: HM Passport Office photo standards (examiner guidance, March 2026)).
