35×45 mm Photo
35×45 mm (about 1.4 × 1.8 inches) is the most common passport photo size in the world. It's used for UK and many European passports and visas, and it's the size most schools, nurseries and membership cards in the UK and Europe ask for.

Don't let your photo get rejected
These are the most common rejection reasons — SnapID checks for them before you pay.
Wrong background color
Using white when cream is required, or off-white when pure white is needed. Our AI detects and flags background issues instantly.
Shadows on face
Overhead or side lighting creates shadows that cause rejection. SnapID checks for even lighting on both sides of your face.
Incorrect head position
Head tilted, turned to the side, or not centered in the frame. Our AI measures exact positioning against official rules.
Eyes not visible
Closed eyes, hair covering eyes, or glare from glasses. Especially common with babies — our AI checks for this.
Wrong dimensions
Each country has exact size requirements. SnapID auto-crops to the precise dimensions needed for your destination country.
Blurry or low-resolution photo
Out-of-focus or heavily compressed photos get rejected. SnapID checks sharpness and resolution before you pay.
